Hazardous procedure: Scientific Glassware Cleaning
Step 1. Identify hazards and hazardous jobs
Ref. #
Identify hazards by:
1
- Consulting with workers
2
- Reviewing incident and injury
3
reports

Examples:

List & describe the hazards and hazardous jobs
Priority
Glass breakage during cleaning operations, leading
to cuts or puncture wounds to skin
Poisoning or sensitization (allergic reaction) due to
exposure to strong chemical cleaning agents
Chemical burns due to contact with acids or alkalis
during cleaning of glassware with eg. nitric acid
High temperature burns due to contact with hot
glassware immediately after washing in dishwasher
Infection after exposure to glassware containing
biohazards that have not been decontaminated
Poisoning / sensitization / chemical burns after
exposure to glassware containing toxic/corrosive
chemicals that have not been removed by prior
rinsing and correct disposal

- Carrying heavy materials
- Trip hazard in walkway
- Repetitive action without break
- Driving a long distance
Step 2. Assign priority for each hazard and hazardous job
For each of the hazards and hazardous jobs listed in Step 1, record a priority rating in the column beside that
hazard/job after referring to the matrix below. The likelihood of injury will be reduced if effective risk control
measures are already in place eg., safe operating equipment and procedures, trained staff etc.
Found a hazard? Think about:
How severely could it hurt someone? 
How likely is it to hurt someone?

very likely ++
could happen regularly
!!! kill or disable
!! several days
off work
! first aid

likely +
could happen occasionally

The numbers show how important it is to do something:
1 do something immediately
6 do something when possible.
