SPECIAL RISKS Specific Hazard(s): Emits toxic fumes under fire conditions. SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes. 6 - Accidental Release Measures PERSONAL PRECAUTION PROCEDURES TO BE FOLLOWED IN CASE OF LEAK OR SPILL Evacuate area. PROCEDURE(S) OF PERSONAL PRECAUTION(S) Wear self-contained breathing apparatus, rubber boots, and heavy rubber gloves. METHODS FOR CLEANING UP Absorb on sand or vermiculite and place in closed containers for disposal. Ventilate area and wash spill site after material pickup is complete. 7 - Handling and Storage HANDLING Directions for Safe Handling: Do not breathe vapor. Avoid contact with eyes, skin, and 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 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. 9 - Physical and Chemical Properties AppearancePhysical State: Liquid ALDRICHwww.molbase.com PropertyValueAt Temperature or Pressure pH N/A BP/BP RangeN/A MP/MP RangeN/A Flash PointN/A FlammabilityN/A Autoignition TempN/A Oxidizing Properties N/A Explosive Properties N/A Explosion LimitsN/A Vapor PressureN/A Partition Coefficient Log Kow: 0,015 ViscosityN/A Vapor DensityN/A Saturated Vapor Conc.
