RISK ASSESSMENTS


Risk assessment is the process of analyzing a risk for its potential and its severity. Knowledge and
the assessment of risk provide the basis for deciding the priority and adequacy of control measures.
AL HABBAI CONTRACTING L.L.C, will remove risks associated with the execution of jobs or will
arrange to reduce them to acceptable levels. Identification, consequences, control and recovery
from the hazards posed by each work activity shall be covered by a risk assessment.

The risk assessment is part of job specific method statement and will be used to educate the
workers during toolbox talks regarding the health and safety hazards of the job on hand.

Assessing risks is also necessary to determine the relative importance of risks, deciding on the
severity of the hazard and the probability of occurrence. This will help in deciding methods of
control. This knowledge is necessary so as to identify where to place the major effort in prevention
and control and in order to make decisions on the adequacy of control measures.
a. The following procedures will be followed on this project:
1- For all major activities, the risk assessment will be prepared with the method
statement to ensure that all risk will be identified.
2- The Project Manager will consider and review the possible health and safety risks
refined from the method statement. This will then be documented by completion of
the health and safety risk assessment form.
3- The key elements will be listed and entered as risk-assessed i.e (H) high, (L) low,
(N/A) not applicable.
23.1 Low Risks:
Where a low risk is identified the details of that risk can be communicated to the workforce
at the relevant time as part of the induction or toolbox talk programmed.
23.2 Medium or High Risks:

For each or medium risk identified, the assessment will be done and the control measures
applied in conjunction with Engineers and Supervisors to reduce the assessed risk to an
acceptable standard i.e. to Low risk status.
The communication of the agreed methods and procedures defined in risk assessments
and method statements will take place to work commencing.
Site Engineer or Supervisor will brief to their respective workmen and this briefing will be
signed and documented in toolbox talk record.
For ensuring the control measures have been adequately implemented, competent
supervisors will monitor activities on a routine basis as commensurate with the risks
involved. Copies of all risk assessments and the method statements will be maintained.

H S E MANUAL










CONSTRUCTION INDUSTRY REGULATIONS

Subpart L – Scaffolds
29 CFR 1926.450 – 29 CFR 1926.454



INTRODUCTION
An estimated 2.3 million construction workers deal with scaffolding each year. More than 9.500 workers
are injured and 80 are killed in scaffolding – related accidents.
Both the OSHA General Industry Safety Standards and constructions safety standards include lenghtly
requirements for scaffolding.
DEFINITIONS:
Brace : A tie that holds one scaffold member in a fixed position with respect to
another member.
Coupler : A device for locking together the component parts of a tubular metal
scaffold which shall be designed and used to safety support the maximum
intended loads.

Light duty scaffold : A scaffold designed and constructed to carry a working load not to exceed
25 pounds per square foot.
Medium duty scaffold : A scaffold designed and constructed to carry a working load not to exceed
50 pounds per square foot.
Heavy duty scaffold : A scaffold designed and constructed to carry a working load not to exceed
75 pounds per square foot.
Guard-rail : A railed secured to uprights and erected along the exposed sides and ends
of platforms.
Maximum intended load: The total of all loads including the working load, the weight of the scaffold,
and such other loads as may be reasonably anticipated.
Toe board : A barrier secured along the sides and ends of a platform, to guard against
the falling of material.
TYPES OF SCAFFOLDING
A. Frame Scaffolding:
The primary steel scaffolding system. It is primarily for rectangular jobs where access is not too
restricted. Frame scaffolding is very popular with masons, plasterers, etc; and is also used
extensively as rolling towers for internal work (electricians, heating, air conditioning, painting,
etc.). frame scaffolding is relatively simple and fast to erect, provided the surface is level, and
the access is not restricted.
B. Tube and Clamp:
To accommodate jobs too difficult for frame scaffolding because of obstructions, limited access,
and the need to scaffold non-rectangular shapes. In many cases, tube and clamp is used together
with frames.

105
Main Cont. : AL HABBAI CONTRACTING LLC

H S E MANUAL

Tube and clamp is simply a steel version of the old access scaffold which historically were made
from lumber.
Tube and clamp requires much greater expertise to erect, and takes much longer to erect than
frames. Most popular in industrial applications such as oil refineries.
Confined Space
No person shall be required or allowed to enter any chamber, tank, vat, pit, pipe, flue or other
confined space in any construction site in which any gas, fume, vapour, dust or oxygen deficient
atmosphere is likely to be present as to involve risk to persons, unless:
a. Certified by complement person based on test carried out by himself that the space is
free from dangerous gas, vapours, fume, dust or oxygen deficient atmosphere.
B. Before an employee enters a street opening such as manhole or an unvented vault, it shall
be promptly protected with a barrier, temporary cover, or other suitable guard.
C. When work is to be performed in manhole
— No entry shall be permitted unless forced ventilation is provided or, the atmosphere is
found to be safe by testing for oxygen deficiency and the presence of explosive gases
or fumes;
— Where unsafe conditions are detected, by resting or other means, the work are shall be
ventilated and otherwise made safe before entry.
— Provisions shall be made for an adequate continuous supply of air.
Work in Manholes
A. While the work is being performed in manholes, an employee shall be available in the
immediate vicinity or render emergency assistance as may required.
B Before using open flames in a manhole or excavation in an area where combustible gases or
liquids may be present, the atmosphere of the manhole or excavation shall be tested and
found safe or cleared of the combustible gases of liquids.
Work Condition (on or over water)

A. Employees working over or near water where the danger of drowning exists shall be provided
with approved life jacket or buoyant work vests.
B. Ring buoys with at least 30 meters of line shall be provided and readily available for emergency
rescue operations. Distance between ring buoys shall not exceed 60 meters.
C. Al least one life saving sift (boat) shall immediately available at locations where employees
are working over or adjacent to water.
ILLUMINATION
1. General :- Construction areas, ramps, runways, corridors, offices, shops and storage areas
shall be lighted to not less than the minimum illumination intensities listed.

Modular System Scaffolds
Modular systems, like tube and clamp, are used for applications where frames cannot be used or
where it is not efficient to use frames (limited access, obstructions, uneven surface, non-
rectangular shapes). The advantage that modular systems have over tube and clamp is that they
do not require the high degree of expertise that tube and clamp does. With modular systems, the
locations of the connections are fixed. As such, once the base is set, the rector does not have to
worry about the location of connections (as he would with tube and clamp), and his erection time
speeds up significantly.


Mobile elevated working platform:

 Only trained and competent personnel will erect all mobile towers
 Mobile scaffold will only be used on firm and leveled ground
 Mobile scaffold will not be pushed or moved when men/ material on it

 While moving the scaffold from one location to another, ensure the route is clear from
obstructions above and below.

 Wheel s will be turned outwards to provide maximum base dimensions and wheel brakes
will be locked when being used.

 The maximum height for a mobile scaffold shall not exceed 3.5 times the minimum of its
base width.

 Where the height increases, it has to be properly tied to a permanent structure or base
weight or provided with adequate out riggers.

 All scaffold towers will have green scaffag to show they are safe for use. When the red sign
is visible, it is unsafe and will not be used until inspected and provided green tag.
