Facilities at the Retford plant include a number of separate buildings involved in manufacture of polymer and composite products to suit an extensive client base.
Hazardous activities in the main process area were based around fabric preparation and application of rubber solutions within dedicated equipment. Routine dispensing of Toluene and general handling of flammable materials used in polymer formulations applied in this area plus subsequent oven-drying.
Fires or explosion hazards arise when flammable vapour is released into areas where there is an ignition source – for example dispensing materials close to unprotected electrics. Solvents such as MEK can even be ignited by a low energy static discharge where vapour is within the flammable explosive range. It is well above its flashpoint at normal ambient temperatures and it’s vapour is heavier than air.
