Table 4:

Preventive measures to minimize occupational exposure to beryllium

Prevention category	Example of preventive measures
1. Elimination and substitution	Job retraining — to alternative role without beryllium exposure Metal substitution — replace metals containing higher levels of beryllium with those containing low or no beryllium
2. Engineering measures	Local exhaust ventilation: remove beryllium particles at the source before worker exposure
3. Administrative measures	Job assignment — alternative tasks that reduce exposure to beryllium Area restriction — restrict access and number of workers to areas with high beryllium exposure Education — on exposure risks and health hazard of beryllium, with mention of becoming sensitized
4. Personal protective equipment	Respirators^* — full-face air-purifying respirator with P100 filters Work clothes — coveralls, gloves, hoods, boots and helmets that protect the skin from exposure and secondary respiratory exposure^†
