The spilled acid should be contained and cautiously diluted to a minimum of 5 or 6 times its original volume with water. The water should be added gradually to the acid to minimize spattering.* During the dilution process, personnel should stand as far away as possible from the spill to avoid contact with the acid and with the corrosive fumes that will be emitted.
A qualified person should determine the degree of dilution and the need for neutralizing the acid before recovering it or discharging it to a wastewater treatment facility.
Care should be taken to ensure that acid leaks, spills, or drainage do not come in contact with sulphide materials, because of the danger of evolving toxic and flammable hydrogen sulphide gas.
Once the spilled acid has been cleaned up, the contaminated area should be thoroughly washed or saturated with water. When the wash water can be collected, it should be discharged to a wastewater treatment facility designed to neutralize acidic wastes.
