HEALTH & SAFETY IN THE SCIENCE LAB: RISK ASSESSMENT
For use in conjunction with the Lab Safety Manual.
Activity
Associated Hazards/Risks
Receipt of chemicals into the
laboratory
Unknown chemical properties and safe
handling/storage requirements
Handling and managing
toxic/dangerous chemicals
Chemicals that require special permits,
licensing requirements and so on
Inadequate and/or unavailable storage
facilities
Chemicals delivered to wrong area or
an area not appropriately set up for
receipt of chemicals
Temporary storage are inappropriate
location/facilities
Damaged packaging:

 Chemical risk assessments
 Rationalizing chemical supplies
to ensure:
o ordering minimum
quantities
o compatibility of chemicals
o adequate storage facilities
and space available
o all required signage and
PPE is available
 Substituting less toxic
chemicals where possible

areas.
For example corrosive chemicals
stored under a sink and not a purpose
built corrosives locker
Toxic fumes
Chemical spills and leaks
