Protective equipment: Standard fire-fighting equipment should be worn along with
self-contained breathing apparatus, and full (impervious)
Emergency measures in case of spillage: Protective clothing should be worn including rubber or
plastic gloves, safety spectacles/goggles and an appropriate
respirator. Vacuum or sweep up powder, minimising dust and
transfer solid waste to a suitable, sealable container. The
spillage site should then be washed with water.
Handling: Care should be taken to avoid skin and eye contact and
gloves and safety goggles or spectacles should be worn. A
high efficiency particulate filter respirator (approved to
EN136 standard) should also be worn as SQ 26999 is a fine
