Change gloves immediately if a spill on gloves is
observed. Wash hands after use.
OTHER SAFETY INFORMATION
Transportation Follow guidance given in the laboratory safety manual
for transport of chemicals.
Storage
• Can be stored with other dry chemicals but in
a dedicated section for toxic chemicals.

Strong acids, strong bases, strong oxidizing agents
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 2 kg): Small spills may be
cleaned by sweeping up dry powder and placing them
in a container. If the spill is a liquid, cover with
absorbent material and then place the absorbent
material container. Clean area with soap and water
once spill is removed.
Large spills (greater than 2 kg): If the spill is in a
