Safety Handbook for
Construction Site Workers
Introduction
Most accidents can be prevented by taking simple
measures or adopting proper working procedures. This
handbook is intended to outline important issues on safety
and health that should be paid attention to on construction
sites for easy reference by the workers. If we work carefully
and take appropriate safety measures, there will definitely
be fewer work injury cases, and our sites will become a safe
and secure place to work in.
The Occupational Safety and Health Ordinance, which
came into operation on 23 May 1997, covers most workplaces
in order to protect the safety and health of employees at
work. Other legislation applicable to construction sites
includes the Factories and Industrial Undertakings Ordinance
and its subsidiary legislation, particularly the Construction
Sites (Safety) Regulations.
Employees' Responsibilities
Employees should cooperate with their employers and
other persons in complying with the safety legislation and
guidelines, and should not do anything to endanger
themselves and other persons.

Basic Rules for Safety
Tidy up construction sites
■
■
■
■
■
■
Keep passages clear all the time.
Sort out materials and pile them up safely. The stacks should not be
too high.
Beware of floor openings and ensure that they are fenced or covered.
Remove refuse as soon as possible.
Provide sufficient lighting.
Familiarize with the location and the operation of fire-fighting equipment.
Safety measures
■
■
■
■
■
■
■
Before you operate a machine, ensure that the dangerous part of the
machine has been installed with a guard.
Avoid going to any area with insufficient lighting as there may be some
dangerous places which have not been provided with fencing.
Keep vigilant all the time and watch out for moving cranes, hooks or
other lifting equipment.
Before you use any electrical installation or tool, check the condition of
its electric cables.
Avoid dragging electric cables on the ground or allowing the cables to
come into contact with water.
Use electrical tools installed with an earth leakage circuit breaker.
Use and handle chemicals with care.
Personal Safety
■
■
■
■
■
Wear protective equipment.
Do not drink or take drugs while working.
Pay attention to personal hygiene.
Do not play in the workplace.
Report to your supervisor immediately if you notice any unsafe condition.
2
Emergency Response to Accidents
You should have a good understanding of your working environment
and the instructions given by your supervisor. When evacuation
is required in an emergency, you should keep calm and find out :
■
■
■
What dangerous situation the alarm refers to.
The routes for evacuation.
The safe place that you should go to as designated by the company.
When someone is found seriously injured, you should :
■ Keep calm.
■ Seek help immediately.
■ Accompany the injured person.
■ Assist in the immediate rescue work as far as possible.
■ Call the site safety staff.
■ Do not try to move the injured person unless it is really necessary
to do so.
■ Do not tamper with the accident scene while waiting for the arrival
of the investigation team.
When a fire breaks out, you should remember :
■ Put out the fire with a fire extinguisher if it is a small fire.
■ If the blaze is out of control, do not try to extinguish the fire on your
own. Call the Fire Services Department right away.
Emergency telephone numbers :
■ Always pay attention to the emergency telephone numbers posted
on the notice board in the site office.
