Process: Mixing various concentrations of aqueous acid
solutions.
Hazard: Contact hazard.
Protective
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.

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).
