Transcript of D Part 12 Flammables
Flashpoint of less than 32oC
Small quantities of liquid may be kept in ordinary workrooms which are either safe by position or are of a fire-resistant structure
Every tank, cylinder, store room etc used for storage of LPG to be marked “Highly Flammable -LPG”
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)
No smoking - the use of the stores for a “quick smoke” is a particular hazard
Heating equipment - no portable heaters
Incoming goods - especially baled materials, should be inspected for incipient fire or smouldering
Any repair or maintenance work carried out in the stores should be supervised. Blow lamps & cutting equipment are a particular hazard
Fire-fighting equipment should be suitable for the risk e.g. fire class, and be properly maintained. All staff should be instructed in its use and other emergency procedures e.g. evacuation, raising alarm and calling fire brigade
Limitation of damage - Should a fire occur, damage will result from the fire itself, from water & from smoke. These causes can be minimised by spacing, to limit spread and allow access between stacks. Keeping water sensitive goods off the floor and keeping drains clear will greatly reduce losses
Compartmented or separated store; up to 4 hour fire resistance
Not located where it could hinder escape in event of fire
Incorporate means to prevent liquid escapes
Located at ground level
All ignition sources (rubbish, vegetation) should be eliminated
Area should be ventilated to the open air
Store and containers should be marked
Stored outside on an impervious surface (concrete)
No container should be stored within 2m of any door, plain glazed window, or escape route
Small containers in work rooms may be stored, provided that:
The total quantity does not exceed 50 litres
When not being used they are kept in a store of non-combustible construction
Safe storage of small quantities of highly flammable
substances in fire-resisting cabinets
Quantities greater than 50 litres should be stored in a properly designated store,
either in the open air (on well ventilated, impervious ground, away from ignition
sources) or in a suitably constructed storeroom
Storage in the workroom
Safety containers with self-closing lids should be used for dispensing and applying small quantities of flammable liquids
Rags & cloths which have been used to mop up or apply flammable liquids should be disposed of in metal containers with well fitting lids and removed from the workplace at the end of each shift or working day
All stores & workrooms must be ventilated to reduce vapour concentrations.
All naked flames & smoking must be prohibited
Tools, spanners and wrenches used for opening drums must be of non-sparking alloy
Zoned electrical equipment
Trained competent staff
High levels of supervision
Fire fighting equipment
Emergency procedures
