Monitoring and health surveillance
The regular review of the health of employees exposed
to health risks. Purpose to:
● detect health effects early
● prevent further harm
● check the effectiveness of control measures
● check the accuracy of risk assessments
● identify and protect workers at increased risk
● evaluate data to reduce health risks.
31
31
Monitoring and health surveillance
Monitoring required:
● serious health risk on failure of controls
● there is a workplace exposure limit
● there is the chance that control measures
are not working properly
Retention of records
● Identifiable individual for 40 years
● General monitoring for 5 years.

Hazardous substance assessment
By the end of the session learners will be able to:
● define the terms ‘hazard’ ● outline the types of information that
and ‘risk’ should be referred to for the safe
● describe how risk assessments identification and use of hazardous
reduce accidents and ill health substances
at work ● describe the general procedures
● outline the 5 steps to risk that should be in place for dealing
assessment with an incident involving
hazardous substances
● outline the control hierarchy in
respect of safe use, handling, ● describe how risk assessments
transporting, storage and disposal reduce accidents and ill health
of substances hazardous to health at work.

Hazards and risks

The 5 steps to risk assessment
1 Identify the hazards
2 Determine who may be harmed and how it may occur
3 Undertake an evaluation of the risk
4 Record your findings and implement any actions identified
5 Review the assessment and update as necessary.

Bar Silica Tetanus
Garage Hair colourant Hepatitis B virus
Tattoo salon Legionella Asthma
Spa pool Ink toner Burns
Quarry Bloodborne virus Dermatitis
Bakery Bacteria Skin cancer

Evaluation of risk
Harmful Extremely harmful
Slightly harmful (resulting in time off (causing major injury or
(requiring first aid)
work) death)
Highly
unlikely Trivial risk Tolerable risk Moderate risk
Unlikely
(could occur Tolerable risk Moderate risk Substantial risk
sometime)
Likely
(not surprised Moderate risk Substantial risk Intolerable risk
if it did happen)

Evaluation of risk
Do we need to do more to reduce
risk?
Consider the hierarchy of controls
to reduce risk so far as is reasonably
practicable.
40
40
3 Hierarchy of control
Number the controls from 1 to 9 in order of effectiveness
Ensure general ventilation through open doors and windows
Eliminate the use of the hazardous substance altogether
Change the work process so less of the substance is produced
Use local exhaust ventilation at the point of source to extract the hazardous
substance
Replace the substance with a less hazardous one
Fully enclose the work process so no hazardous substance escapes
Change the form of a substance to a safer one
Reduce the number of workers exposed to the hazardous substance
Provide personal protective equipment (PPE).
41

Record and implement
What information would need
to be recorded?
How may the findings of the risk
assessment be implemented?
