All HFLs must be stored in one of the following:  Fixed storage tanks in a safe position   Suitable closed vessels in a safe position in the open air, where necessary being protected against direct sunlight  Suitable closed vessels kept in a store room, either safe by position or of fire-resisting structure  In the case of a workroom where the aggregate quantity does not exceed 50 litres, in suitable closed vessels in a suitably placed cupboard or bin that is a fire-resisting structure

All LPGs to be stored in one of the following ways:  Suitable underground reservoirs or in suitable fixed storage  tanks, in a safe position, either underground or in the open air In suitable movable storage tanks/vessels kept in a safe  position in the open air In pipelines or pumps forming part of an enclosed system  In suitable cylinders kept in safe positions in the open air or,  where not reasonably practicable, in a store room constructed of non-combustible material, with adequate ventilation, in a safe position, of fire-resisting structure and solely used for storage of LPG and/or acetylene cylinders

Separate from manufacturing,  accommodation, public access, garages & equipment which may produce a fire hazard At least 2 access points to allow escape  Doors & gates should be shut when not  required to allow passage of goods. Locked when not in use Segregation of different types of good (e.g.  packets, drums, cylinders etc.) in different areas

Stacked goods:  Keep stacks as small as is practical   Keep stacks away from walls and off floor by using pallets  Stacks should not be close to lights, alarm points, fire- fighting equipment or sprinklers  Stack should not block drains Housekeeping:  Inspect stores regularly   Waste & debris should not be allowed to accumulate for fear of fire All electrical equipment within the area should be of  a standard related to the risk (zoned)
