Information Sheet #1

1.1 Kinds, Uses and Properties of Cleaning Solvents

™ Kinds of Cleaning Solvents

Solutions are homogeneous mixture of two or more components. They can be gaseous,
liquid or solid. When we speak of a solution, we usually think of a solid dissolved in water.
While water is the most common solvent, other liquids are frequently employed as solvents for
certain substances – for example wax maybe dissolved in gasoline. The dissolved material in a
solution is termed as solute (e.g. wax) while the dissolving medium is called solvent (e.g.
gasoline). However, the term can be interchanged depending on which substance is of greater
amount.

Solvent is a component of a solution that dissolves solute and is usually present in large
proportion or amount. It can be classified as polar or nonpolar. Polar solvents are solvents
which dissolve/are soluble in water; while nonpolar solvents are solvents which do not
dissolve/are insoluble in water.

Solvents usually used for cleaning in automotive shops are: water, gasoline, kerosene,
thinner and detergent soap.

The table below shows the kinds of cleaning solvents based on their solubility in water.

Cleaning Solvents Solubility in Water Polar Nonpolar
x
a. water soluble x
b. gasoline insoluble x x
c. kerosene insoluble x
d. thinner insoluble
e. detergent soap soluble

™ Properties of Cleaning Solvents

A useful generalization much quoted is that “Like dissolves like”. More specifically, high
solubility occurs when the molecules of the solute are similar in structure and electrical
properties to the molecules of the solvent.

When there is a similarity of electrical properties; e.g. high dipole element between solute
and solvent, the solute-solvent attractions are particularly strong. When there is dissimilarity,
solute-solvent attractions are weak. For this reason, a polar substance such as H2O usually is a
good solvent for a polar substance such as detergent soap but a poor solvent for a nonpolar
substance such as gasoline.

1. Gasoline
2. Diesoline - It is used to wash oil engine, transmission and other
parts of the vehicle.
3. Kerosene
4. Thinner - It is used to remove dust, grease oil, paint, etc.

5. Soap and water - It is used to remove spilled paint on the floor, walls and
tools.

- It is used to wash/clean upholstered furniture such as
seats, tables, cabinets, etc.

1.2 Occupational Health and Safety Practices in Handling Cleaning Solvents

A great percentage of eye injury and cuts results from a disregard for the simplest of rules
in handling cleaning solvents. You should never use compressed air to clean your clothes,
hands or body. The pressure could cause the cleaning solvents and dirt particles to penetrate
your skin, resulting in infection and /or blood poisoning. Do not use compressed air to clean an
object immediately after it has been removed from a hot cleaning tank. First, rinse the cleaning
solvents away with water. Do not use carbon tetrachloride as a cleaning solution. The fumes,
when inhaled can cause serious internal injury and possibly result in death. When steam-
cleaning, place the object to be cleaned on a pallet and wear a face shield and rubber gloves
for protection against loose debris.

If a job or cleaning task requires the use of gloves, use the appropriate gloves. Do not for
instance use welding gloves when removing an object from a hot tank, or rubber gloves when
welding. If you have cut, nicked, or burned yourself, or something has got into your eyes, report
immediately to the first-aid person.

Keep all inflammable cleaning solvents in closed tin containers and whenever possible,
store them in a separate area.

Information Sheet #2

2.1 System of Measurement and Conversion of Units

A general searching for new ways can be done without precise measurements. But the
reasoning and planning stages of the scientific method are effective only if observations are
measured accurately and results are recorded in a way that can be understood when they are
needed again.

Any measurements of quantity require systems of units. Measurements of the natural
world require units to describe length, volume, mass, time, temperature and a number of
properties that can be described by combinations of these units. We also need methods to tell
how many we have of the units and how accurate we have made the measurement.

™ Metric System and The System International (SI)

Most of the world now uses a system of measurement units called the metric system. It
avoids many of the problems in changing units by using decimal relationships between units.
The metric system has been the generally accepted system for scientific measurements with a
basic unit of length, the meter, a unit of volume, the liter, and a unit of mass, the gram.

In 1960, the recognized international authority on units adopted a variation of the metric
system intended to simplify conversions even more. This official system is called Systeme
International d’Unites (in French) or the International System of Units (in English). By
agreement, it is abbreviated SI in all languages. SI attempts to assign a single uniform unit for
each measurable quantity – such as distance, mass or volume.

™ Unit Conversion

One effective method of converting from one kind of unit to another is the unit factor
method. This method depends on two simple facts. First, any quantity can be multiplied by the
number 1 without changing the amount. Second, any number divided by itself. Anytime we can
write down an equality we can set up unit factors. We can write down the equality.

2.54 cm = 1 in

From it we can write either

2.54 cm = 1 in
11

2.54 cm = 1 or 1 in = 1
1 in 2.54 cm

Both of them are quality being divided by itself.

ALT723205
May 28, 2004 July 15, 2004 12

Table 1 lists some of the equalities we find very useful in relating English and Metric
System units. As long as we know the conversion from English to Metric for each type of unit
(length, volume and mass) we can multiply our original amount by a series of unit factors until
we reach the desired answer. Because each equality gives us two unit factors, we pick the
ones and cancel out the units we started with and lead us toward the answer.

Table 1

Length Volume Mass
12 in = 1 ft 16 oz = 1 lb
3 ft = 1 yd 2 pt = 1 qt 2000 lb = 1 ton
4 qt = 1 gal
2.54 cm = 1 in 454 g = 1 lb
1000 mm = 1 m Conversion between system 1000 mg = 1 g
100 cm = 1 m 1.06 qt = 1 liter 1000g = 1 kg
1000 m = 1 km 1000 ml = 1 liter
1 cm = 10 mm 1 cm3 = 1 ml

Example:

A four-cylinder spark-ignition engine is sliced into two so that the pistons and cylinders can
be seen. Each cylinder is about 4 inches in diameter. What is the diameter of cylinder in
millimeter (mm)?

Solution:

Step 1: What is the given information?
Diameter of each cylinder is 4 inches

Step 2: What units are needed?
Convert inches to millimeter (mm)

Step 3: Map the route from the given information to the answer
inches cm
cm mm

Step 4: Start from the beginning and put in the unit factors so units cancel out.

4 cm x 2.54 cm x 10 mm = 101.6 mm

Information Sheet #2

1.1 Types of Tools and Equipment

There are three main types of tools/equipment in the shop. One type is known as hand
tools because your hand supplies the energy to operate them. The other type is called machine
or power tools/equipment. Electricity, compressed air, or hydraulic pressure operates these
tools. The last type is referred to as measuring tools.

™ Hand tools
They include screwdrivers, hammers, pliers, wrenches and pullers.

1. Screwdrivers are used to drive, or turn screws. The most common type has a single flat
blade for driving screws with slotted heads.

2. Hammers are the ones you use most in the shop. They should be gripped on the end
of the handle.

3. Pliers are special types of adjustable wrenches. The two legs move on a pivot so that

Information Sheet #4

1.1 Why Maintain Inventory of Tools and Equipment

The most importance advice you can be given at the beginning of your career is to
purchase top-grade tools. These are made from high-quality steel and manufactured to
precision. Special care is necessary so that the tools/equipment can be properly maintained
thus preventing loses. Since you, the technician must work with your tools daily, regular
inventory of tools/equipment is very important.

The initial cost of even a minimum number of tools is high but the accompanying warranty
guarantees satisfaction and many years of service. It is better, in the long run, to start with a few
carefully selected tools that will take care of your most common needs and then gradually build-
up to a complete set. It is sometimes hard to identify and memorize the huge number of tools
and equipment in the workshop, hence maintaining the inventory record is of great value.
