Risk assessment: 5 Vital steps to ensuring safety

Step 1. Hazard identification
 
  • Gather information about hazards in the laboratory.
  • Review the work and working practices. What hazardous substances are present or likely to be present in the laboratory ? How are they hazardous and what effects could they have? Who could  be exposed and how?
Step 2 : Risk assessment
 
  • Decide who might be harmed and how. Consider how laboratory practice could be changed. How close are people to the substances? How often is exposure likely to occur and how long for? What levels of exposure are there? Assign a risk rating.
Step 3: Decision making
 
  • If the hazard is a risk to health and safety, decide whether existing  precautions are adequate   or more should be done.
Step 4: Record keeping
 
  • Record what needs to be  done in terms of prevention  and or control of exposure
Step 5: Regular review .
 
  • If the risks are  serious and/or likely to change
    • Monitor whether precautions recommended in step 4 are in place. If this is not the case bring it to the attention of a health and safety officer
    • review frequently
    • If  circumstances changed significantly –review immediately (Go to step1)
    • Is the assessment still valid ? If not , amend it.

Risk rating and Risk levels (how to determine risk rating and risk levels)

Firstly you must assess the likelihood. What is the chance in the period of a year that an untoward incident or an injury will occur due to the hazard. This can be given a number rating in terms of likelihood:

Likelihood
Number
Rare 1
Unlikely 2
Possible 3
Likely 4
Almost Certain 5

 

Then you must assess the consequences associated with the risk. In the even of an untoward incident or an injury how severe would the consequences be? This can again be given a number rating in a similar way to the above:

Likelihood
Number
Insignificant 1
Minor 2
Moderate 3
Major 4
Catastrophic 5

 

Risk rating can be calculated by multiplying the likelihood and the consequences

Likelihood x Consequences

Risk level: If this number is, or is in excess of 10, the risk must be eliminated immediately

 

Risks associated with common hazards in the cytology laboratory
