CLEANING AND INSPECTION
WARNING
• Skysol 100 solvent is combustible; DO NOT use or store near
heat, sparks, flame, or other ignition sources. Use mechanical
ventilation whenever product is used in a confined space,
heated above ambient temperatures, or agitated. Keep
container sealed when not in use.
Contact with Skysol 100 may cause skin irritation. Use
chemical-resistant gloves. In case of skin contact, remove any
contaminated clothing and wash skin thoroughly with soap
and water. Wash contaminated clothing before reuse. Eye
contact may cause irritation, tearing, or blurring of vision. Use
face shield or goggles when eye contact may occur. In case of
eye contact, flush eyes with large amounts of water for at
least 15 minutes or until irritation subsides. Inhalation may
cause irritation to upper respiratory passages. DO NOT have
food or drink in the vicinity. Failure to comply may result in
injury to personnel.

When cleaning with compressed air, eyeshields must be worn.
Failure to wear eyeshields may result in injury to personnel.
