A Quick Guide to Risk Asssment
Part 1: Introduction
What is Risk Asssment?
It is the process of:
1.Identifying and analysing safety and health hazards
associated with work
2.Asssing the risks involved and
3.Prioritising measures to control the hazards and
reduce the risks
Why should we do Risk Asssment?
Risk asssment allows us identify the hazards at the workplace and implement effective risk control measures before they escalate into accidents and injuries.
Under the new Workplace Safety and Health (Risk Management) Regulations, every workplace, including factories, should conduct risk asssments for all routine and non-routine work undertaken.
How is Risk Asssment done?
Prior to conducting Risk Asssment, adequate preparation must be done. A risk asssment team
should be formed, preferably consisting personnel from the various levels of participation in the work activity. Relevant information should also be collated to facilitate better understanding of the work process.
Having completed the preparation work, workplace risks may then be assd in 3 simple steps:
1.Hazard Identification
2.Risk Evaluation
3.Risk Control

Hazard Identification involves identifying the hazards associated with the activity of each process and type of potential accidents or incidents. During this pha, the aim is to spot hazards, brainstorm on all the possible types of accidents and ill health that can happen due to the hazard, and identify the persons that can be victims of the accident or ill health.
STEP 1: Hazard Identification
Types of accident, incident and ill health may include: √Person falling from height
√Object falling from height
√Slips or falls on the same level
√Electrocution
√Asphyxiation
√Drowning
√Noi induced deafness
√Dermatitis
√Collap of structure
√Fire and explosion
√Struck by or against object
√Soft tissue damage (sprains, strains) Persons-at-risk may include:
√Persons directly involved in the operation
陈旧反义词√Persons not directly involved in the operation √Visitors to the workplace
√Members of the public You may wish to consider the following when trying to look for instances of hazardous work:
Method of repeated tasks and unsafe work practices
Electrical and mechanical hazards
Excessive manual material lifting, pulling and pushing
Excessive exposure to corrosive substances
unguarded machines
Temporary scaffolds
Environmental slippery surfaces, lighting, unstable soil conditions
Layout and location of equipment
A simple way of identifying hazards for a particular work activity is to divide the work activity into the major steps of carrying out the work and analy the steps individually for the prence of hazards. It is also important to differentiate between hazards and accidents or ill-health, which are events caud by inadequate control of hazards. The following chart illustrates the method of identifying hazards systematically and also gives examples for hazards leading up to certain events:
