INHALATION EXPOSURE If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen. DERMAL EXPOSURE In case of contact, immediately wash skin with soap and copious amounts of water. EYE EXPOSURE Contamination of the eyes should be treated by immediate and prolonged irrigation with copious amounts of water. Assure adequate flushing of the eyes by separating the eyelids with fingers. Section 5 - Fire Fighting Measures FLAMMABLE HAZARDS Flammable Hazards: Yes EXPLOSION HAZARDS May form explosive mixtures with air Container explosion may occur under fire conditions. FLASH POINT 269.6 °F 132 °C Method: closed cup EXPLOSION LIMITS Lower: 15 % Upper: 25 % AUTOIGNITION TEMP 651 °C FLAMMABILITY N/A EXTINGUISHING MEDIA Suitable: For small (incipient) fires, use media such as "alcohol" foam, dry chemical, or carbon dioxide. For large fires, apply water from as far as possible. Use very large quantities (flooding) of water applied as a mist or spray; solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. FIREFIGHTING Protective Equipment: Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes. Specific Hazard(s): Vapor may travel considerable distance to source of ignition and flash back. Emits toxic fumes under fire conditions. Flammable gas. Specific Method(s) of Fire Fighting: Do not extinguish burning gas if flow cannot be shut off immediately. Use water spray or fog nozzle to keep cylinder cool. Move cylinder away from fire if there is no risk. Section 6 - Accidental Release Measures PROCEDURE TO BE FOLLOWED IN CASE OF LEAK OR SPILL Evacuate area and keep personnel upwind. Shut off leak if there is no risk. Shut off all sources of ignition. PROCEDURE(S) OF PERSONAL PRECAUTION(S) <strong>ALDRICH</strong> - 294993 www.sigma-aldrich.com Page 2
Wear self-contained breathing apparatus, rubber boots, and heavy rubber gloves. METHODS FOR CLEANING UP Ventilate area and wash spill site after material pickup is complete. Section 7 - Handling and Storage HANDLING User Exposure: Do not breathe gas. Do not get in eyes, on skin, on clothing. Avoid prolonged or repeated exposure. STORAGE Suitable: Keep tightly closed. Use with equipment rated for cylinder pressure, and of compatible materials of construction. Close valve when not in use and when empty. Make sure cylinder is properly secured when in use or stored Cylinder temperature should not exceed 125°F (52°C). SPECIAL REQUIREMENTS Contents under pressure. Section 8 - Exposure Controls / PPE ENGINEERING CONTROLS Safety shower and eye bath. Warning: suck-back into cylinder may cause rupture. Use back-flow-preventive device in piping. 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 AXBEK - P3 (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. Other: Faceshield (8-inch minimum). GENERAL HYGIENE MEASURES Discard contaminated clothing and shoes. Wash thoroughly after handling.
