GENERAL 
Petrol/gasoline vapour is highly  flammable  and in confined spaces is also  very  explosive  and toxic. 
When 
petrol/gasoline evaporates  it produces 150 times  its  own  volume in vapour,  which when  diluted  with air 
becomes  a readily 
ignitablc mixture.  The vapour  is heavier  than air and  will always  fall  to the  lowest  level. It  can 
readily  be distributed throughout  a workshop  by air  current,  consequently,  even a small  spillage 
of petrol/gasoline is 
potentially  very...
