Type B bags are constructed from insulating fabric but have a breakdown voltage less than 6 kV. This provision prevents the risk of energetic propagating brush discharges which can ignite dust-air mixtures and flammable gases and solvent vapors. Type B bags may be used in the presence of the combustible dusts with MIE of greater than 3mJ, but only in the absence of flammable vapors of gases. Type B bags are sometimes called antistatic bags, but it should be noted that Type B only provides limited protection against static electricity and they do not provide any mechanism for dissipating static charge.
