OTHER SAFETY INFORMATION Transportation Follow guidance given in the laboratory safety manual for transport of chemicals. Storage • Store in a flammables materials storage cabinet. • Keep away from heat or sources of ignition • Keep tightly sealed • Monitor for formation of explosive peroxides Incompatible materials include: Oxygen, oxidizing agents, halogens, reducing agents, perchlorates, trimethylaluminum Spill/Accident Procedures For all spills: • Wear two pairs of nitrile gloves • Turn off sources of ignition (if safe) • Evacuate the immediate area Exposure: • If anyone exposed requires emergency medical attention, dial 911 (or 9-911 from landline). • Follow procedures outlined in laboratory safety manual. Small spills (less than 500 mL): Cover the spill with absorbent materials. Place absorbent materials in bag or bucket for collection by EHS. Clean area with soap and water once spill is removed. Large spills (greater than 500 mL): If the spill is in a chemical fume hood, contact the EHS director (864- 710-2933).
