The difference between fire and explosion protection is the available response time to minimize the damage created. Comparison to Fire Protection Explosions The difference between fire and explosion protection is the available response time to minimize the damage created. A fire load in a dust extraction system can exist due to the following conditions. Filter elements consist of natural, synthetic or organic material (paper, cotton, needle felt, and plastic granulate) and are therefore classified as combustible. Basically, a fire load exists. The thermal value, e. g. for polyester is 6.3 kWh/kg. Secondary flammable sources such as oily air, aerosols or other foreign matter leave residues in the filters and ductwork, which easily ignite. The fire load increases by the dust accumulation in the filter if the material collected is also flammable. The combustion factor can vary between CF 1 and CF 6 depending on the type of dust (see table below).

A fire load in a dust extraction system can exist due to the following conditions. Filter elements consist of natural, synthetic or organic material (paper, cotton, needle felt, and plastic granulate) and are therefore classified as combustible. Basically, a fire load exists. The thermal value, e. g. for polyester is 6.3 kWh/kg. Secondary flammable sources such as oily air, aerosols or other foreign matter leave residues in the filters and ductwork, which easily ignite. The fire load increases by the dust accumulation in the filter if the material collected is also flammable. The combustion factor can vary between CF 1 and CF 6 depending on the type of dust (see table below).
