| Abstract |
Existing Chemicals Information Sheet. Epidemiological and experimental data suggest that sodium hydroxide (NaOH) is not a skin sensitizer or reproductive toxicant, and that it has no genotoxic or carcinogenic properties. NaOH is, however, is a potent corrosive and the observed acute toxicity and reported dermatitis following prolonged exposure appear to be a consequence of this corrosive potential. Thus, the primary health effect of NaOH is corrosivity, with local irritation observed at lower concentrations. Consequently, the risk of irritation or corrosion to humans from exposure to NaOH will depend on the amount of exposure to the chemical. NaOH use and exposure are well regulated in Australia: it is classified as corrosive, has an exposure standard set for the occupational environment (NOHSC 1995, 8h TWA and 15min STEL: 2mg/m3), and is included in the Schedule of Drugs and Poisons and the Australian Dangerous Goods Code. |
