7 - Handling and Storage

---

HANDLING
Directions for Safe Handling: Do not breathe vapor. Do not get
in eyes, on skin, on clothing. Avoid prolonged or repeated
exposure.
STORAGE
Conditions of Storage: Keep tightly closed.

---

8 - Exposure Controls / Personal Protection

---

ENGINEERING CONTROLS
Use only in a chemical fume hood. Safety shower and eye bath.
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 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.
Hand Protection: Compatible chemical-resistant gloves.
Eye Protection: Chemical safety goggles.
