Section 7 - Handling and Storage
ALDRICH - 663301 www.sigma-aldrich.com Page 2
HANDLING
User Exposure: Avoid contact with eyes, skin, and clothing.
Avoid breathing vapor. Avoid prolonged or repeated exposure.
STORAGE
Suitable: Keep tightly closed. Keep away from combustible
materials, heat, sparks, and open flame. Store in a cool dry
place. Handle and store under nitrogen.
Incompatible Materials: Do not allow contact with water
SPECIAL REQUIREMENTS
Handle and store under inert gas. Air sensitive.
Section 8 - Exposure Controls / PPE
ENGINEERING CONTROLS
Use only in a chemical fume hood. Safety shower and eye bath. Use
nonsparking tools.
PERSONAL PROTECTIVE EQUIPMENT
Respiratory: 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: Compatible chemical-resistant gloves.
Eye: Chemical safety goggles.
GENERAL HYGIENE MEASURES
Wash contaminated clothing before reuse. Discard contaminated
shoes. Wash thoroughly after handling.
