prevent small spills and leakage to avoid slip hazard. Material can accumulate static charges which may cause an electrical spark (ignition source). When the material is handled in bulk, an electrical spark could ignite any flammable vapors from liquids or residues that may be present (e.g.., during switch - loading operation). Use proper bonding and /of earthing procedures. However , bonding and earthing may not eliminate the hazard from static accumulation. Consult local applicable standards for guidance.
