HANDLING User Exposure: Do not breathe vapor. Do not get in eyes, on skin, on clothing. Avoid prolonged or repeated exposure. STORAGE Suitable: Keep tightly closed. Keep away from heat and open flame. Store at 2-8 C Section 8 - Exposure Controls / PPE ENGINEERING CONTROLS Safety shower and eye bath. Use only in a chemical fume hood. 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. Other: Wear appropriate government approved respirator, chemical-resistant gloves, safety goggles, other protective clothing. GENERAL HYGIENE MEASURES Wash thoroughly after handling.
