Element 3: Work Equipment Hazards and Control

Additional precautions are necessary when storing and
handling petrol. It should be stored in an appropriate,
labelled metal container in a well ventilated secure area
away from ignition sources. It should be handled with
care in a well ventilated area (preferable outside) away
from ignition sources. Any spillages should be dealt with
immediately (see Element 5).

Additional precautions must be taken when using
electrical equipment. Battery-operated tools might be
used or low voltage supply (e.g. 110 v rather than
230 v). Damage to the electrical flex must be avoided.
The tool, flex and plug should be routinely inspected by
the operator prior to use. It should also be given a formal
electrical safety inspection and thorough examination
and test (see Element 4).

Revision Questions

3. (a) From what do the risks in the use of
hand tools arise?

(b) From what do the additional risks of
portable power tools arise?

4. Why might each power tool be marked?

(Suggested Answers are at the end of Unit IGC2.)

If one part of the course material proves difficult,
skip over that section and carry on with the

Element 3: Work Equipment Hazards and Control

• The mechanical hazards of machinery are: crushing, shearing, cutting or severing, entanglement, drawing in or
trapping, impact, stabbing or puncture, friction or abrasion, and high pressure fluid injection.

• The non-mechanical hazards of machinery are: electricity, noise, vibration, hazardous substances, radiation
(ionising and non-ionising), extreme temperatures, ergonomics, slips, trips and falls, and fire and explosion.

• Protection from machinery hazards can be achieved by using guards that physically enclose the hazard and
prevent contact. Fixed guards are most effective at preventing contact, but interlocked guards, adjustable guards
and self-adjusting guards may be required.

• If it is not possible to completely guard in a hazard then other forms of protection will have to be used such
as trip devices, two-hand controls, protective appliances, emergency stops, PPE, or information, instruction,
training and supervision.

• Guards and safety devices must meet relevant standards: be strong and robust; compatible with machine
operation; not easy to defeat; allow visibility and ventilation; take maintenance into account; and not increase
overall risk.

Machinery Hazards and Protection – Principles

Key Information

Mechanical and Non-Mechanical
Hazards
The hazards of machinery can be divided into:

• Mechanical hazards – mainly from contact with or
being caught by dangerous moving parts.

• Non-mechanical hazards – mainly from the power
source or things emitted by the machine.

This follows ISO 12100:2003 (Parts 1 and 2) “Safety of
Machinery”.

Mechanical Hazards
The mechanical hazards of machinery can be further
subdivided into the following classes:

Crushing – the body is trapped between two moving
parts or one moving part and a fixed object (e.g. a
hydraulic lift collapses crushing a person underneath it).

Shearing – a part of the body (usually fingers) is trapped
between two parts of the machine, one moving past the
other with some speed. The effect is like a guillotine,
shearing off the trapped body part.

Shearing – a finger put through the spokes of this wheel
will be sheared off

Crushing – the person is crushed between the moving
object and the wallR

Element 8: Chemical and Biological Health – Hazards and Risk Control

Summary
This element has dealt with some of the hazards and controls relevant to chemical and biological health hazards in the
construction environment.

In particular this element has:

• Outlined the different forms of chemicals (liquids, gases, vapours, mists, fumes and dusts) and biological agents (fungi,
bacteria and viruses).

• Identified the classification of chemicals (toxic, harmful, corrosive, irritant and carcinogenic) and the meaning of the
terms “acute” and “chronic” when used to describe their effects.

• Identified the main routes of entry into the body (inhalation, ingestion, absorption through the skin and injection
through the skin) and some of the body’s defence mechanisms.

• Explained the factors to be considered when undertaking an assessment of the health risks from substances
encountered in construction workplaces.

• Outlined the sources of information available about the substances, and the use of data sheets and product labels.

• Described some of the equipment that is used when undertaking basic surveys to assess concentrations of substances in
the workplace (e.g. stain tube detectors).

• Explained the purpose and principles of occupational exposure limits and their relevance in short-term and long-term
exposures.

• Outlined the control measures that should be used to reduce the risk of ill-health from exposure to hazardous
substances

• Described the Principles of Good Practice as regards to controlling exposure to hazardous substances: minimising
emissions; taking into account routes of exposure; exposure control to be proportional to risk; choosing effective
controls; using PPE; regular checks and reviews of controls in place; provision of information and training. Control
measures should not increase the overall risks.

• Described common measures to implement the Principles of Good Practice: eliminate or substitute; change the
process; reduce exposure time; enclose or segregate; LEV; dilution ventilation; RPE and PPE; personal hygiene; and
health surveillance.

• Outlined the hazards, risks and controls associated with specific hazardous agents.

• Described the generation and control of dusts on a construction site, in particular cement and wood dusts.

• Described the health risks and controls associated with asbestos and the duty to manage asbestos.

• Outlined the basic requirements related to the safe handling and storage of waste on construction sites.
