Highly Flammable Liquids (HFL’s), including petroleum based adhesives, are used extensively throughout the construction industry and carry with them the risk of fire, serious accidents and injury.
Main points:
• Always look for the hazard symbol and wording on containers.
• Only ever have the minimum quantities at the place of work. Keep the remainder in suitable stores.
• Always keep the lid on containers when not is immediate use, and store correctly.
Discussion points:
• Always follow the manufacturer’s instructions.
• Keep away from open flames and sources of heat (HFL’s ignite at relatively low temperatures).
• Do not smoke in areas where HFL’s are used or stored, and do not use equipment which generates heat and/or sparks (including electrical sparks).
• HFL vapours are generally heavier than air and will accumulate at ground level if they cannot disperse. Beware of drains, excavations, pits, etc, both when using and storing HFL’s.
• HFL vapours can also be toxic, make you drowsy, etc. Only use in well ventilated areas, or, if this is not possible, respiratory protective equipment may have to be worn.
• HFL storage should comprise containers made of non-flammable material (don’t forget the vapour hazards – ensure there is ventilation).
• Clear up any spillage immediately and safely dispose of contaminated cleaning materials. If inside a building, consider assisting vapour dispersal by opening windows, doors, etc.
• Consider covering drains to protect against entry by substance or its vapour where necessary and practicable
