Section VII - EMPLOYEE PROTECTION

CONTROL MEASURES: General room ventilation required. An eyewash and safety shower should be nearby and ready for use.

RESPIRATORY PROTECTION: If use conditions generate dusts, wear a NIOSH- approved respirator appropriate for those emission levels. Appropriate respirators may be a full face-piece or a half mask air-purifying cartridge respirator with particulate filters, a self- contained breathing apparatus in the pressure demand mode, or a supplied-air respirator.

PROTECTIVE CLOTHING: Long-sleeved shirt, trousers, safety shoes, rubber gloves, and rubber apron.
