Abstract Study on pickling and acid vat hazards submitted to the Regional Technical Committee for the Metal Trades (Comité technique régional de la métallurgie), Lille, France. Required specifications for acid storage premises and tanks, and precautions to be taken in filling tanks (especially by the compressed-air method); hazards of pickling processes (splashes when preparing acid vats or dipping metal parts, acid fumes during hot pickling processes); preventive measures (fixing of metal part to prevent slipping, limitation of height of pickling vats, drainage of overspill towards neutralising baths, safe distances for workers, rim of pickling vats sufficiently high to prevent workers from falling in, fume exhaust (rim exhaust plus push-pull ventilation on vat lip). The hazards involved in the regeneration of sulfuric acid baths are mentioned.
