Process: Mixing various concentrations of aqueous acid solutions.
Hazard: Contact hazard.
Equipment: Safety goggles, nitrile, PVC, or neoprene gloves. Avoid skin contact; serious burns may result. Gloves made of nitrile, neoprene, or PVC can provide effective skin protection. Wear safety glasses or chemical safety goggles with face shield when using large quantities. Wear rubber, neoprene, or PVC apron when using large quantities and splash potential exists.
Ventilation: Use concentrated acids in fume hood. A safety shower and eyewash must be available and accessible when working with corrosive liquids.
Procedures: Store mineral acids together, separate from oxidizing agents and organic materials. Store acetic acid and other organic acids with the combustible organic liquids.
Procedures: Skin contact: Rinse affected skin with plenty of water while removing contaminated clothing and shoes. Rinse for at least 15 minutes. Seek medical attention.
Eye contact: Splashes may cause tissue destruction. Wash eyes for at least 15 minutes, lifting the upper and lower eyelids occasionally. Seek medical attention immediately.
FOLLOW SPILL PROCEDURE FOR SPILL CLEANUP
Disposal: All waste shall be placed in closed containers, properly labeled and moved to the Hazardous Waste Accumulation area (a brick structure by the SGM).
Labeling: Whenever acid solutions are mixed and kept for storage, they must be clearly marked with the concentration and a description of its hazards. Always use full chemical name on label (not chemical formula).
