8 - Exposure Controls / Personal Protection

---

ENGINEERING CONTROLS
Safety shower and eye bath. Use only in a chemical fume hood.
GENERAL HYGIENE MEASURES
Wash contaminated clothing before reuse. Wash thoroughly after
handling.
PERSONAL PROTECTIVE EQUIPMENT
Respiratory Protection: 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 particle respirator type N100 (US)
or type P3 (EN 143) respirator cartridges as a backup to
engineering controls. If the respirator is the sole means of
protection, use a full-face supplied air respirator.
Hand Protection: Compatible chemical-resistant gloves.
Eye Protection: Chemical safety goggles.
