Section 6. Accidental Release Measures
Small Spill Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by
spreading water on the contaminated surface and dispose of according to local and regional authority
requirements.
Large Spill
Isolate spill area and provide ventilation. Vacuum up spill using a HEPA air filter or use a shovel to pick up the
spilled material and place material in a closed container for proper disposal. Take care not to raise dust. Finish
cleaning by spreading water on the contaminated surface and allow to evacuate through the sanitary system. Be
careful that the product is not present at a concentration level above TLV. Check TLV on the MSDS and with
local authorities.
