For general cleaning and inspection instructions, refer to WP 0013 00.
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.
