Risk Management

Risk Management

Definitions:

Hazard

Something with the potential to cause harm.

 Risk

8The likelihood that the harm will be realised.

When assessing risks the potential severity of the consequences is also considered.

Laws requiring risk assessment

  Section 2(1) HASAWA 1974
 The Control of Substances Hazardous to Health Regulations (COSHH) 1999  
 The Control of Lead at Work Regulations 1998
 The Construction (Health Safety and Welfare) Regulations 1996
 The Display Screen Equipment (Health and Safety) Regulations 1992 

5 Steps to Risk Assessment

 Look for the Hazards
 Decide who might be harmed and in what circumstances
 Evaluate the risks, and the adequacy of existing controls
 Record the significant findings
 Review the assessment

Step 1 - Identify the hazards

A Hazard is something with the potential to cause harm
Physical
Chemical
Biological
Ergonomic
Psychological

Hazard Identification Techniques

Inspections
HAZOP
Job Safety Analysis
Hazard Books and Contact Schemes
Fault Tree Analysis

Step 2 - Decide who might be harmed & how?

 Consider groups who may be especially at risk
  the disabled, pregnant workers, children  and young workers

Step 3 - Evaluate the risks

 Consider the likelihood and severity
 Are existing controls adequate?
 Is there anything else that can be done to make it safer (SFAIRP)?
 Are legal standards met and best practice followed?

General Principles of Prevention

avoiding risks;  
evaluating the risks which cannot be avoided;  
combating the risks at source;  
adapting the work to the individual
adapting to technical progress;  
replacing the dangerous by the non-dangerous or less dangerous;  
developing a coherent prevention policy, relating to the working environment;  
giving collective protective measures priority over individual protective measures;   
giving appropriate instructions to employees. 

Step 4 - Record significant findings

 You must decide what the significant findings are, they may include;
the significant hazards
the existing control measures
identification of workers affected
reference to other guidance

Step 5 - Review the assessment

The assessment must be reviewed when:
You believe it is no longer valid
There has been a significant change in the matters to which it relates.
the workplace
new work rates
new process or plant
competency of individuals 
new legal requirements

A safe system of work

“A safe system of work is a formal procedure which results from a systematic examination of the task in order to identify all the hazards. It defines safe methods to ensure that hazards are eliminated or risks minimised.”
Nothing is absolutely safe
Nilsson v. Redditch Borough Council

Develop a safe system of work

Analyse the task

Implement the system
Monitor the system
Materials,Equipment, Environment and People(MEEP)
Environment
Temperature,Lighting,Noise,Ventilation etc.

People
Systems,Training,Skills,Motivation,etc.

Materials
Use,Handling,Storage,Transportation,Disposal etc.

Equipment
Design,Ergonomics,Maintenance,Inspections,etc.

  1. HAZOP is perfect for large and elaborate systems. So far as HAZOP is concerned, it's a HAZard and Operability Study. Lastly though hazop is well-known as a risk assessment technique, it's also useful from an operability viewpoint.
