OTHER SAFETY INFORMATION
Transportation Follow guidance given in the laboratory safety manual
for transport of chemicals.
Storage
• Can be stored with flammable materials

Incompatible materials include:
Strong oxidizing agent, strong bases, amines, alkali
metals, metal powders
Spill/Accident Procedures
For all spills:
• Wear two pairs of nitrile gloves
• 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 in a hood or 50 mL
outside a fume hood): 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 in a hood or 50 mL
outside a fume hood): If the spill is in a chemical fume
hood, contact the EHS director (864-710-2933). If he
cannot be reached (does not answer phone, do not
leave voicemail), then call 911, pull the fire alarm and
exit the building. If the spill is outside of a hood, then
call 911, pull the fire alarm and exit the building.
