Exposure Controls/Personal Protection

Personal Protection

Compatible chemical-resistant gloves. Chemical safety goggles. Protective clothing.

Respirators

Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator.
