INFORMATION SHEET 7.5-2
Lifting Procedures of Timber Truss

Learning Objectives:

At the end of this Information Sheet, the trainee/student must be able to:

1. Know proper timber truss lifting procedure; and
2. Lift timber truss following correct process.

Introduction:

Although most builders do handle trusses with care, some have never been
properly instructed. This is a summary of the basic requirements for the proper
handling of trusses during installation. Workplace, health and safety requirements
is another subject on its own that builders should take into consideration.

Lifting Points
Trusses should never be lifted using a single lifting point and certainly not from
the apex joint. There should be at least two lifting points for each truss located
between one third to one half of the truss span apart. These lifting points should
always be at, or very close to, web panel joints and not a mid- panel point or off.

System 63

Slings or Spreader Bars

For spans of less than 9m, trusses may be lifted with slings. Each leg of the sling
should make an angle no more than 60° apart at the top. For spans greater than
9m, spreader bars should be used. As an alternative, a strong back can be
attached to multiple points along a truss to spread the load and stiffen the truss.

Orientation during Lifting

Chains should be attached at points above the center of gravity of the truss and
equidistant from it so they are level during lifting and land squarely on their
supports. They should also be lifted upright rather than on their side, as flexing
them on their side will put great strain on both timber and nail plated joints. Some
trusses are not as symmetrical as they may appear. For example, they may be
cantilevered on one side or rely on internal supports. Additional care must be
taken to ensure that they are located on their supports the right way around so
that support points marked on the truss actually rest above their supports.

Temporary Bracing

In the process of standing trusses on their supports, it is important to ensure that
adequate temporary bracing is in place to secure them against buckling and
collapse. Adequately secured temporary bracing is necessary to ensure the
assembly is stable before leaving the roof unattended.

Manual Lifting

Short trusses are sometimes lifted by hand rather than by crane. They may be
placed on top of the walls by pulling up on skids no more than 3m apart, taking
similar precautions as above.

Handling your trusses with care will ensure they are in the best condition to carry
the design load and assure a safe and trouble free roof for the life of the building. A

INFORMATION SHEET 7.6-1
Proper Methods of Lifting and Moving Panels

Learning Objectives:
At the end of this Information Sheet, the trainee/student must be able to:
1. Adhere correct proper lifting and moving panels

Introduction:

When handling individual metal roof panels, handling practices differ from one
product to another. There are several reasons for this difference. Non-structural
panels tend to be more fragile due to their smaller rib dimensions.

Structural panels with larger trapezoidal rib profiles are also fragile until installed
into place and interlocked with the rest of the roof system. Softer metals, like
copper, zinc, and annealed stainless steel, are easily damaged in comparison to
carbon steel or a high tensile aluminum alloy.

Metal roofs are strong and lightweight, the individual roof panels are fragile and
awkward to handle. Roof panels are long, some up to 30 feet or more in length.
Panels should not be handled by one individual, but by two or more persons,
depending on the panel style and size.

The usual method for handling longer panels is to lift and carry them from a seam
edge in front of the chest. Both proper and improper methods of handling are
illustrated in Figure.

To prevent panel damage, always use as many workers as necessary, lift and lower
in unison, and properly place the panels. When laid down on the ground or roof,
long panels require multiple points of support beneath them.

Installation Procedures of Roofing Sheets and Accessories

Learning Objectives:
At the end of this Information Sheet, the trainee/student must be able to:
1. Know proper roofing sheet installation; and
2. Install roofing sheet following correct procedure and methods

Introduction:

Image taken from google

Pierce-fixing uses fasteners to attach the sheet to the roof frame. Screws should be
fixed perpendicular to the sheeting or cladding in the middle of the rib, and always
at the top of the crest for maximum water tightness. Screws can be fixed through
the pan/ valley or crest for walling applications.
Concealed fixing uses fasteners and clips and this method means that the screws
will be hidden underneath the exterior of the roof sheets. Clips are affixed using
double sided facings and at regular intervals along the sheeting according to site
requirements.
Please note that these two types of fixing are used for different types of metal
roofing. If you’re not sure which is best for your type of roofing, ask us.

Before you start

Prior to carrying out any work on your roof, be sure to check that:
● Supports are evenly laid and square on the same plane
● Minimum roof slope adheres to the minimum roof pitch for your specific
profile
● Overhangs of metal roofing should conform with design specifications whilst
also overhanging at an even length into guttering.

DO NOT lay further sheets if any sheeting is uneven or crooked (This will save you
a lot of remedial work, which can be very hard work indeed).
Orient sheets before lifting

For best weatherproofing, begin installing your sheeting on the side opposite the
prevailing wind.

Position your sheets on the ground before raising to the roof for laying. Sheets
should be checked to ensure that the top side faces upwards. The overlapping
sheet edges should be raised facing the direction of installation, i.e., positioned the
same way as the other sheets.

DO NOT place sheeting in a position where it isn’t fully supported, to avoid
bending.

Laying the first sheet of roofing

Make absolutely sure the first sheet laid is properly positioned.

Ensure that:
● Sheeting is properly aligned
● Both ends are properly positioned in accordance with the roof plan.

Proceed to the next sheet only when you’re sure your sheeting is 100% accurately
laid.

Position your next sheets

After fixing the first sheet in position, align the following sheets using:
● The long edge of the previous sheet; and

System 63

● A measurement from the end of the sheet to the fascia or purlin at the
gutter.

It is important that you keep the gutter-end of all sheets in a straight line. Fix the
sheet by either:

● Fixing each sheet completely, before laying the next; or
● Fix the sheet sufficiently to ensure it can’t move, complete laying all sheets,

then return to place all the intermediate fasteners later.

Check roofing alignment regularly

Be sure to keep an eye on each metal roofing sheet to ensure they are properly
aligned in relation to the first sheet.
Take two measurements across the wide face of the sheeting and compare. They
should be the same.

Image taken from google

Errors and alignment problems?

At intervals during the job, perform a similar check. Measure from the finishing

line. The last sheet should be aligned in direct parallel with the end of the roof. If
sheeting is slightly misaligned, lay subsequent sheets accordingly to correct the
alignment:

● Properly align and fix the sheet.
● Fix the opposite edge of the sheeting, with fasteners or clips nearer or

farther from the position they would be on the correct alignment.

Progressively fix alignment so sheets are brought back in to the proper
position.

Working with side-laps and pierce-fixed sheets
To avoid moisture entering laps by water action, metal sheets are slightly modified

to manage this problem. All profiles are designed for only one rib to be overlapped
to ensure the water tightness. Sheets must be properly affixed according to the
type of sheeting you’re using.

Five Rib Roof Sheets

Span Roofing Roof Sheets

Place the first sheet and following sheets with their side-lap fitting closely over the
sheet laid before it. Ensure that sheets are fitting well at each stage of laying until
the final end of the sheet has been laid.
This is actually pretty easy:

● Position the bottom end of the sheet by measuring from the end of the sheet
to the fascia or purlin;

● Secure the sheeting with vice grips/clamp;
● The upper end of the sheet: should meet the side-lap very closely; check

positioning, and fasten the sheet when you’re happy with its position.

Crest fixing

Pierce fixing on crests is always recommended when using the following roof
profiles for roofing applications:

● Corrugated roofing

● Curving Quality
● Five Rib roofing

● Span roofing
Crest fixing may also be used on the above products when these are used for
walling applications, however valley fixing is more common for walling.

Pierce fixing on valleys is recommended when using the following profiles for
walling applications:

▪ Corrugated roofing
▪ Curving Quality
▪ Five Rib roofing
▪ Span roofing
▪ Mini Corrugated
▪ Mini Rib

Fasteners are used placed in the valleys of wall cladding due to the following:
▪ They are less visible and don’t break up the aesthetic lines of the sheets
▪ There is no risk of the profile being deformed as it will rest flat against its
support
▪ Water penetration will not occur

Although when valley fixing you will always require a side-lap fastener in all laps
at each support. It works out to be more economical to with labour, time and with
the cost of fasteners to use a crest fastener at each side-lap in place of the lap
fastener and adjacent valley fastener.

INFORMATION SHEET 7.7-1
Dismantling Procedures

Learning Objectives:

At the end of this Information Sheet, the trainee/student must be able to:

1. Know correct process in dismantling scaffoldings; and
2. Dismantle erected/constructed scaffoldings.

Introduction:

Scaffolding creates a safe and secure platform for people working at elevated
levels. They're often used at construction sites or on remodeling projects to provide
easy access to ceilings and building facades. Once the job is complete and it's time
to remove the scaffolding, special care must be taken in order to ensure that the
job's done safely.

Image taken from google

Things You'll Need
● Safety harness
● Appropriate safety gear

● Scaffolding tools
● Extra scaffolding components

Instructions:

Step 1
Clear a nearby space to set the dismantled pieces of scaffolding down. As a
scaffold is dismantled, the components should immediately be removed from the

structure and set aside for later inspection. There should also be room enough to
provide truck access to transport the scaffolding parts to a loading area.

Step 2
Examine the entire scaffold structure. Starting with the base, make sure that the

structure is sound and that there are no visible hazards. Any ties that have been

System 63

removed at an earlier time must now be put back in place. Check each individual
platform to ensure that the wood hasn't been damaged during construction. Wood
that has been damaged should be removed and replaced.

Step 3
Put on all necessary safety gear. Safety shoes, hard hats and gloves should be
worn along with any other gear required by the site conditions. Safety harnesses
should also be worn when on the scaffold structure.

Step 4
Begin the dismantling project at the top of the scaffold. Remove the guardrail and
posts first using the necessary tools. Pass the components down from person to
person in a daisy chain formation. Make sure not to stand in a location where
pieces can be dropped on you.

Step 5
Remove the remainder of the platform from the section below. The ties holding the
structure secure to the building should only be removed once the entire platform
they support has been removed. The dismantling process works exactly the same
as the construction process only in reverse.

Step 6
Examine all of the scaffolding components once they've been removed. Parts that
cannot be repaired should be set aside for later disposal as faulty equipment can
lead to injury. All of the undamaged and repairable pieces should be safely stored
away for transport off site.

Tip
Avoid handing loose coupling/stacking pins by attaching them to the top of the
frame below. Keeping them fastened to the structure lessens the risk of them
falling on workers below.

Warning
A safety harness should be worn at all times. The force necessary to remove
components such as ties can cause a person to lose their balance.

Ways of Improving Productivity

Learning Objectives:

At the end of this Information Sheet, the trainee/student must be able to:

1. Know principle of improving productivity in the workplace; and
2. Adapt applicable principle for the enhancement of the

organization/compony

Introduction:

Construction is an extremely important job for accuracy. However, clients usually
want their buildings and projects done as quickly as possible. This is why it’s
important to stress productivity with your construction workers. This article will
give you 10 tips to improving productivity at work.

1. Communicate Clearly

Communication is the most important productivity booster in any job. No one will
get the job done well if they have no idea what’s going on. It’s important you
clearly communicate your goals to your crew before you start a new project and
continue keeping them updated throughout the project.

Send out frequent emails and memos if there are any changes that might affect
your workers. Be considerate and never leave your employees in the dark about
what’s happening in a project.

2. Set Realistic Goals

Rome wasn’t built in a day and your new building won’t be either.
Construction takes time so it’s important you set realistic goals. Make sure the
entire crew understands the goal for each day, each week, each month, and even
each year. It’s important that people have goals to strive towards each and every
day. Setting small goals makes a big project seem easier to accomplish.

3. Reward Regularly

Construction is often hot and tiring work. Your workers are putting in hour after
hour of manual labor. In order to increase productivity, offer incentives in the form
of rewards. Whenever your crew meets a goal, treat them to pizza and beer at a
local restaurant. This will make your workers feel appreciated and eager to push
forward.

4. Train Your Troops

One thing that will quickly squash productivity is inadequate training.
If you want a work site the runs efficiently, you have to train your workers. Make
sure they’re all trained before you begin a project.

Yes, this will often cost extra money but it will be worth it. Training also reduces
the number of injuries on a job which will, in turn, increase productivity.

5. Listen Well

To be a good leader, you have to listen well to those you’re employing. It’s not
enough to communicate with people if you’re not open to hearing their responses.
Your workers will have a firsthand idea of what does and doesn’t work on site.
They will sometimes come to you and tell you that a goal isn’t realistic, or that
they need new tools. Don’t brush these things off. Instead, take them into
consideration and try to find a solution for your crew.

6. Plan with Purpose

Before starting a construction project, you need to have a detailed plan laid out for
how you’re going to accomplish the job. This includes schedules for workers,
materials needed, and countless other logistics. The more thoroughly you plan
your project beforehand, the better it will turn out. You also need to keep this plan
updated to reflect on how the project is moving.

7. Hire Good Management

Hiring good management is one of the key ways to increase productivity on site. If
you have managers who are respectful yet firm in their leadership, your team will
respond. Managers help keep workers focused and working towards your goals.
Managers also work as middlemen between construction workers and upper
management in order to relay problems.

8. Keep Track of Your Materials

There’s nothing worse than thinking you have enough construction materials to
finish a project only to run out at the last minute. You should be regularly
checking inventory in order to prevent this. You need to make sure you have the
materials to complete at least one week’s worth of work.

Mr. Frazier N. Lunag
System 63

If you don’t, you need to order new materials well in advance to give them enough
time to come in. You don’t want your whole project to screech to a halt because
you didn’t take the time to take proper inventory.

9. Give Your Workers Time Off

As mentioned above, construction is hot and tiring work. It requires a ton of
manual labor that puts stress on the body. In order to increase productivity, it is
important to give you workers adequate time off. If you’ve been working them hard
for a few weeks in a row, give them a long weekend to recover.

This will demonstrate that you care about your workers and they will be happier
for it. When they return to work they’ll be eager to get back to the project after
being well rested.

10. Convey The End Goal

It always helps people stay on task if they’re reminded of what they’re working
towards. Put up pictures of the end result around the site to remind the workers
why they’re working. Maybe they’re building a hospital for the sick or a school for
the young. Construction work is so important as it develops communities and
creates secure spaces for people to live and grow.
Remind your workers of the end result of all their hard work. Show them what an
impact they’re going to make in their community.

Follow This Guide to Improve Productivity at Work
Remember that construction workers want to feel valued as human beings just
like anyone else. If you want to increase productivity at work you need to
incentivize and listen to your workers. Set reasonable goals and reward them for
meeting them.

Once you start communicating well with your construction crew you’ll be thrilled
to see how proactive the job site becomes.

Implementing 3R and 5S

Learning Objectives:

At the end of this Information Sheet, the trainee/student must be able to:

1. Identify the effects of ecology to people; and
2. Comply with ecosystem protection concepts.

Introduction:

Caring for the natural environment and understanding the hierarchy of resource
management. Below are ways you can do just that. Have ideas, thoughts, or want
to share a way you've accomplished one of the 7 Rs

Rethink

Rethink how you view natural resources. Understanding that natural resources
are limited can greatly influence the choices you make in your everyday life. When
purchasing items, remember the words of L.N. Smith, "Every dollar you spend or
don't spend is a vote you cast for the world you want to live in." It is critical to
realize that every choice you make is very important to the health of the planet.

One way to rethink about the choices you make is to conduct an at-home waste
audit. This will allow you to see areas of your life that cause the most waste. Click
here for a template on conducting an at-home waste audit created by The

Conscious Desi. The waste audit might show you that you go through a large

number of plastic water bottles. To reduce this, consider using the same water
bottle over and over again. For a more durable option, consider purchasing a
reusable water bottle that will last, such as stainless steel or glass. You will find
that not only are you saving the environment by not purchasing bottled water, but
you're also saving your wallet

Refuse

Sustainability defines refuse as refusing to accept or support products or
companies that harm the environment. One way to do this is to refuse items that
are over-packaged or packaged in plastic. While it is difficult to refuse all plastic
items, being more conscious can help change your habits.

A great way to refuse over-packaged items is to start your grocery shopping in the
produce section. Not only is this a healthier option, but also the more
environmentally conscious option. Avoid produce wrapped in plastic. Once you
find the package-free produce, use a reusable produce bag instead of the plastic
produce bags offered in the market.

Reduce

Reducing the number of resources used in your everyday life is the next step in
the resource management hierarchy. Start with small ways you can reduce your
energy usage, water usage along with reducing your garbage, food waste, plastic,
and transportation. The room in your home that usually creates the most waste is
the kitchen, therefore you can focus on reducing waste here first to make the
biggest impact. Below is a list of 55 ways to reduce kitchen waste:

9 Tips For Living With Less Plastic
1. Bring your own shopping bag
2. Carry a reusable water bottle
3. Bring your own cup
4. Pack your lunch in reusable containers
5. Say no to disposable straws & cutlery
6. Skip the plastic produce bags
7. Slow down and dine in
8. Store leftovers in glass jars
9. Share these tips with your friends

Another way to reduce is to find items in your home that cause lots of waste and
swap them for more environmentally conscious products. Take paper towels, for

example. Think about the number of resources it takes to grow the trees, chop
down the trees, transport them, refine them into the desired product, package the

paper towels in plastic, transport them home, and then dispose of them in the
garbage. Note, paper towels cannot be currently recycled in Dunedin! Instead of
going through these resources so quickly, consider making your kitchen paperless.

Items to swap for creating a paperless kitchen:
● Swap paper towels for cloth towels

● Swap paper napkins for cloth napkins
● Swap paper plates for reusable plates
● Swap paper cups for reusable cups

Reuse

When you purchase an item, say a can of tomato sauce, think about how you are
paying for the sauce AND the jar or container it comes in. Look around your home
to find the various ways the products you purchase are packaged. Since you are
paying for this packaging - why not make the most of it? There are endless ideas
online. If you cannot reuse an item, share it with someone else; this is called re-
homing. You can donate to a local thrift store or share with your neighbor next
door.
Below are a few examples of ways to reuse the items right in your home.

Repairing items is another way to reduce the consumption of materials and
natural resources. By placing value in the item you have and repairing when
needed, you are sustaining the products you own and reducing waste. There are
many resources online for learning how to repair household items.

Recycle

There are various local recycling programs that you can partake in. Note these are
all separate programs and must be sorted separately.

● Single stream or mixed recycling
o Solid Waste & Recycling offers single-stream recycling to all single-family
homeowners. Residents are encouraged to recycle right in their curbside
program. This means only recycling cans, office paper, newspaper,
cardboard, glass bottles and jars, plastic bottles, jugs, and containers,
and food and beverage cartons.
o Common Contaminants:

TESDA-CAR- CARPENTRY NC II Date Developed: 3-20-20 Revision No.2
PTC-IFUGAO Issued by: FN LUNAG 2nd 3-20-20
Fabricating and

Mr. Frazier N. Lunag
System 63

o Nothing smaller than your fist! Small items including bottle caps,

shredded paper, small yogurt cups, sticky notes, and K-cups are too
small to go through the sorting plant. They become lodged in equipment
and create cross-contamination issues. Either twist the cap on your

bottle so it can be "one item" or throw the cap in the garbage.
o DO NOT BAG YOUR RECYCLING! Make sure all recyclable items are

loose in your cart and no plastic bags are in the cart.

Recycling Program accepts:
● Aluminum, tin, and steel cans

● Paper and cardboard
● All colors glass bottles and jars

● Plastic bottles and containers (#1-7)
● Food and beverage cartons

Make sure to rinse out containers before placing them in your recycling cart.
Items that are common contaminates in Dunedin’s Recycling Program include:

● Plastic bags, wrap, food, packaging or film

● Paper towels, paper plates, paper cups, tissue, and wax paper
● Cords, wires, clothing hangers, garden hose, appliances, string lights, light

bulbs, and clothing – these items become entangled in equipment causing
damage and safety issues.
● Broken cups and dishes

● Styrofoam, foam containers and foam packaging
● Scrap metal, construction and yard debris

● Diapers, hazardous and medical materials, electronics and batteries

Where does your recycling go once you place it in the bin?
Dunedin currently has a recycling contract with Waste Pro. This company picks
up the residential curbside program and transports the materials to a Materials
Recovery Facility (MRF) or sorting plant in Sarasota, Florida. Once the materials
are sorted and bailed, they go out to market. Waste Pro states that they almost
exclusively sell their materials to domestic markets.

Condos, Apartments, and Townhomes
All commercial and multi-family buildings in Dunedin are entitled to the open
market for recycling services. This allows for businesses and multi-family
buildings to have a program that best suits their needs.
Do you live in a condo or apartment that doesn’t have recycling? Speak with your
management to set an appointment with a staff member of Dunedin Solid Waste.
The City’s staff can explain the various recycling options commercial buildings
have and assist them with starting or revamping a recycling program.

● Textile and clothing recycling
o Did you know the City of Dunedin partners with Suncoast Textile
Recycling in Clearwater to offer residents a way to correctly recycle
clothing and textiles? Residents can place clothing, shoes, purses, belts,
and other fabric materials into the drop off bins located at:
▪ Lake Haven Recycling Center – 810 Lake Haven Road, Dunedin
▪ Highlander Pool Recycling Center – 1941 Ed Eckert Drive, Dunedin

● Cooking oil recycling
o Residents can bring used cooking oil to the Dunedin Solid Waste &

Recycling office at 1070 Virginia St, Dunedin. Simply fill a container
with used cooking oil and stop by the office! Let staff know if you'd like
the container back and they will assist you.

o REMEMBER: Never dump cooking oil down drains as this can cause
serious damage! Fat, oil, and grease clog Dunedin's sanitary sewer

system when poured down drains and can cause unsanitary back-
ups, overflows onto streets, foul-smelling odors, and costly damage to
our sewer system. You can help by recycling your cooking oil!

Do:
Use a personal container for transport (wide mouth jugs work great). Recycle beef

and pork grease/margarine, shortening, any fat, grease or oil from food.

Don't:
Put motor oil in containers.

Rot

Rot, also known as composting, is the act of turning food waste and other organics
back into nutrient-rich soil.

According to Paul Hawken's Project Drawdown book, Reducing Food Waste is
Priority #3 for fighting against climate change. This can be accomplished by
understanding the Food Waste Hierarchy demonstrated below.

Food Recovery Hierarchy
1. Source Reduction - cooking using fresh ingredients in small batches.
Trayless dining and taking only what you're going to eat is important.
2. Feed Hungry People - donating to food banks
3. Feed Animals - using food scraps as animal feed
4. Industrial Uses - recycling used cooking oil for biofuels and biodigesters
5. Composting - composting food scraps and coffee grounds
6. Landfill and Incineration - last resort for disposal

INFORMATION SHEET 7.8-2
Organizing Materials to Be Stored

Learning Objectives:

At the end of this Information Sheet, the trainee/student must be able to:

1. Identify proper procedure in organizing materials to store; and
2. Understand principle of material storing.

Introduction:

Site storage involves the provision of adequate space, protection and control
for materials, components and equipment that are to be kept on a construction

site during the building process.

There are several factors to be considered when deciding on the amount and

nature of storage required.
● Physical properties: The size, shape, weight and mode of delivery.
● Organization: The planning process to ensure unloading is available

and storage space has been allocated.
● Control: Processes for checking the quality and quantity of materials on

delivery, and monitoring stock holdings.
● Protection: The necessary protection for durable and non-

durable materials and components from damage.

● Security: Guarding against theft and vandalism.
● Costs: Costs associated with handling, transporting and stacking

requirements, the workforce required, heating and/or lighting that may be

required, facilities to be provided for subcontractors, and so on.
● Processing: What needs to be done to materials before they can be used. Is

there packaging that needs to be removed or returned?
● Programme: When are items required, what is the risk to the project of them

not being available, how long in advance are they ordered and how long they

will be on site.
● Ownership: Who is legally responsible for items, who will be using them and

who owns them? See Materials on site for more information.

Site allocation

The location and size of space to be allocated should be planned carefully as part
of an overall site layout plan and each site will present its own
problems. Failure to adequately plan for storage space can result in congestion, or

having more materials on site than storage space allows for.

The most appropriate position on site in terms of handling, storage and
convenience should be determined. Unloading deliveries should take place in a
clearly marked designated area, away from other site operations, supervised by

a competent person.

The distance between storage areas and the area materials are to be used should
be reduced as much as possible to keep the time and cost required
to transport them from place to place at a minimum.
Alternatively, storage areas could be positioned within the reach of a tower
crane which can then be used to move materials as required.

Theft
Materials and equipment may need protection from theft and vandalism,
particularly when left out in the open where they have the potential to be removed
late at night by opportunistic thieves. Tradespeople often have heavy duty lockable
compartments or vans for storing tools, but where it is more practical to
leave equipment and materials on site, security may need to be provided. This can
be in the form of a lockable fenced compound on site, perhaps
with CCTV, alarms and patrols.

Close boarded fences are often used which are similar to hoarding, or chain
link fencing with precast concrete posts, sometimes incorporating a 45° crank
which faces out.

Health and safety
There are certain health and safety issues to consider when storing items on site.
Items which are stacked must be stable to ensure they will not fall
onto workers. Workers should not climb or walk on top of materials which are
stacked as they could shift and cause them to fall.

Stored items should not block or obstruct escape routes.
The type of material being stored also needs to be taken into account. If it is
hazardous, it may require specific precautions and control measures such
as bunds for toxic substances or it may need to be kept separate from other
substances to prevent a reaction.

To reduce the risk of an accident, special containers are required
to store hazardous chemicals and dangerous goods. These types of containers may
have special provisions for things like natural ventilation, special
compartments, electrical earthing, and warning signs.

Materials storage
Different types of material will have different storage requirements, in particular
depending on whether they are durable or non-durable.

Bricks
Bricks may be delivered to site loose or strapped in unit loads and stored
on timber pallets to be transported using a forklift. Bricks should be stacked on
edge in rows to a maximum height of 2.4 m. It is important that they are stored
on level, well-drained ground and covered with a polythene sheet to protect
against efflorescence and other issues. When calculating the area required
for storage, allowance of around 5 m should be given for the forklift approach.

Blocks
Blocks may be delivered to site loose or strapped in unit loads on timber pallets.

They should be stacked in columns, to a maximum height of 8 courses, and
covered with a protective sheet.

Roofing tiles
Tiles may be delivered to site loose, in plastic-wrapped packs or

in unit loads on timber pallets. They should be stacked vertically in rows, to a
maximum of 6 in height. The tiles at the end of the row should be laid flat and
staggered. Ridge tiles should be stored vertically on end.

Drainage pipes

These are usually supplied loose or strapped together on timber pallets. They
should be stacked horizontally with ends reversed in alternate rows. A driven-
in timber stack or column of loose bricks can be used to form end restraints.

Corrugated and similar sheet materials

These should be stored flat on a level surface and covered with a
protective polythene sheet.

Timber
Timber and other joinery items should be stored horizontally and covered in
a scaffold rack, although provision should be made for free air flow, usually by the

rack having open ends and sides, while having a top that is covered. It is advisable
for different timber sizes to be kept separate.

Cement
Since any contact with direct or airborne moisture can cause cement to set, it

must be kept dry. In terms of organization, it is advisable for a rotational system to
be used, whereby the first batch of cement delivered is the first to be used.

Small quantities of bagged cement should be stacked to a height no more than 1
m, on a raised dry platform such as a timber pallet. A polythene sheet should be

used as cover, with care being made to ensure that it is weighted down around the
edges.

Medium quantities of bagged cement may need to be stored in a watertight and
fireproof shed, with galvanized steel sides and adjustable legs on bearing plates.

Large quantities of loose cement should be stored in a cement storage silo.

Aggregates
It is essential for different aggregate types and sizes to be kept separate. They
should be stored on a clean, hard, free-draining surface, surrounded by retaining

and separating walls of bulk timbers. Stored aggregates should be regularly
monitored for moisture content.
