Evaluation of mutagenicity and other adverse effects of occupational exposure to sodium azide.
The ubiquitous use of sodium azide has resulted in widespread occupational exposure to it in both laboratory and industrial settings, despite a lack of knowledge of the risks which may be involved. Explosive, toxic, and mutagenic hazards have been shown at even low-dose exposures. These effects occur in many species, from cellular damage through pathology of whole systems, and human fatalities have been reported. The advantages to its availability for applicable uses precludes reaching a "no exposure" level, but efforts to decrease unnecessary exposure can reduce its risk; therefore a quantitative procedure for determining human exposure is necessary. However, for various reasons present methods for this type of evaluation of azide are unsatisfactory, and minimizing hazard is dependent upon good laboratory hygiene and motivated personnel. The increasing use of azide and proportionally increasing occupational and accidental exposure in the future warrants the undertaking of chronic exposure studies, which hopefully will result in more explicit guidelines for human protection.
