This is blog will help you develop an inspection checklist for your Class 3 Flammable Liquids cabinets and storage areas. Safety cabinets — like all hazard control measures — must be regularly inspected, reviewed and maintained to meet the requirements of 37 Maintenance of control measures and Section 38 Review of control measures of the WHS Regulations.
- Chemical containers are approved for the storage of Class 3 Flammable liquids.
- Labels are intact, legible and have not been altered or defaced in any way.
- Portable chemical containers are properly labelled and bear the appropriate warning signs/hazard statements.
- Containers have lids and are fully closed when not in use.
- Containers are not leaking and have no visible signs of cracks, puncture marks, breaks, dents, or other damage.
- Containers and drums are clean with no chemical residue or spillage on the top, cap seal, or running down the sides.
- Empty flammable liquids containers have been disposed of properly and safely.

- Containers and drums are completely enclosed inside the cabinet and not blocking the closing mechanisms.
- Doors close automatically in sequence and are held shut automatically (without jamming).

- Cabinet is no taller than 2 metres above floor level.
- Chemical storage area has appropriate warning signs and placards eg, HAZCHEM.
- There is no evidence of smoking, hot work, or other restricted activities within 3 metres of the cabinet.
- Ignition sources, incompatible chemicals, gas cylinders, electronic gadgets and heavy machinery are not located within 3-5 metres of the flammable liquids storage area.
- First aid equipment, emergency showers, and eyewash equipment can be safely accessed within 10 seconds of the cabinet.
- There is a clear path between the cabinet and the emergency shower and eyewash unit — there are no obstructions or barriers in the way.
- Incompatible medical equipment (eg, defibrillators, O2) is not brought (or used) within 3-5 metres of the cabinet.
- Register of Hazardous Chemicals is attached to the cabinet and contains the most recent Safety Data Sheet (SDS) for each chemical inside the cabinet.

- Aggregate quantities are at least 10 metres apart and are not exceeded.
- Ground floor — maximum of 850 litres of flammable liquids per 250 square metres.
- Other floors — maximum of 250 litres of flammable liquids per 250 square metres.
- Lighting in the storage area is sufficient, fully functional, and there are no discharging sockets or switches.
- There is no maintenance or construction work being conducted near (or above) the flammable liquids cabinet.
- Cabinets are protected from impact from forklifts, vehicles, dropped tools and flying debris.
- External contractors and maintenance workers from other departments have received an appropriate safety induction and are monitored (and properly supervised) while in the flammable liquids store.
- Class B Fire Extinguishers and a chemical spill kit (with instructions) are on-hand.
- There are no chemical containers lying around the storage area or sitting next to the cabinet.
- Decanting and transferring of chemicals into portable containers is not being conducted in the storage area.
Ventilation and air quality
- There are no indicators that the air surrounding flammable liquids cabinets is contaminated with flammable vapours. Eg, strong smell around cabinet, visible indicators.
- There are no indicators that chemical concentration levels are above workplace exposure standards. Eg, workers coughing or complaining of stinging eyes.
- Mechanical ventilation system is fully functional.
Other checklist essentials
Your inspection checklist should have blank spaces for the following:
- Date and time of inspection.
- Name and signature/initials of inspectors/auditors.
- Checkbox or compliance indicator next to each item [YES - NO - N/A]
- Details of corrective actions.
- Date the corrective action was implemented.
- Signature/Initials of operator who implemented corrective action.
