13.35 Requirements for stores other than indoor storage cabinets


A hazardous substance location that is a store, other than an indoor storage cabinet, for a class 6 or 8 substance referred to in regulation 13.34(1) must comply with the following requirements:


unless otherwise approved by WorkSafe, the store must be located on a floor that has immediate access for emergency service workers; and


the store can be appropriately secured from access by persons other than those permitted by the PCBU to access the store; and


at least 2 means of access must be provided to a store that has a floor area exceeding 25 m2; and


a store that was built or materially changed after the commencement of this regulation must have wall and roof sheeting and main structural members constructed from materials that are non-combustible and resistant to attack by the substances stored; and


where a toxic substance is likely to present an inhalation hazard (of dusts, mists, or vapours) in a store, adequate natural or mechanical ventilation must be provided that is sufficient to—


maintain the ambient concentration of any dusts, mists, or vapours in the store as low as reasonably practicable; and


where applicable, maintain exposure levels in the store below prescribed exposure standards; and


the store must have a means of either containing a spill or diverting it to a secondary containment system within the boundary of the premises that complies with regulation 13.30; and


all areas used for decanting substances must have floors that are capable of containing a spill or of diverting it to a suitable secondary containment system within the boundary of the premises; and


where provided, and except where they are designed as spill trays, any racks or shelves in the store must be designed and constructed in such a manner as to prevent the accumulation of pooling liquid; and


containers of class 6 or 8 substances must be kept away from sources of heat, be securely closed while not in use, and be kept in such a manner as to avoid spillage; and


containers of class 6 or 8 substances must not be kept near hazardous substances with which they are incompatible or with which they may react dangerously; and


where containers are kept in stacks, the stacks must be arranged in a manner that minimises the possibility of stack collapse and prevents damage to containers in lower layers from loadings exerted by the upper layers; and


in relation to a store where containers are opened, the following items must be provided:


a safety shower:


eye-wash facilities:


water for hand-washing; and


in relation to a store where containers remain closed at all times, water for hand-washing must be provided.


However, a relevant safe work instrument may modify the requirements of subclause (1) for a substance referred to in regulation 13.34(1)(f).
