SODIUM HYPOCHLORITE MATERIAL SAFETY DATA SHEET BLEACH, 10-16% /wt Page 2 of 2 Emergency and First Aid Procedures: Inhalation: Remove to fresh air. If breathing is difficult, call a physician. Chemical Stability: Sodium hypochlorite solutions decompose slowly at normal temperatures releasing low concentrations of corrosive chlorine gas. Decomposition is influenced by temperature, concentration, pH, ionic strength, exposure to light and the presence of metals. Household bleach is, in general, a solution containing 3–8% sodium hypochlorite, by weight, and 0.01–0.05% sodium hydroxide; the sodium hydroxide is used to slow the decomposition of sodium hypochlorite into sodium chloride and sodium chlorate. Cleaning. Sodium hypochlorite has destaining properties.
