Tool Kit, General Mechanics (Appendix B, Section III, item 2).
Materials
Rags, Wiping (Appendix E, Section II, item 3)
Cleaning Solvent (Appendix E, Section II, item 1 )
Clean parts in a well ventilated area. Avoid inhalation of solvent fumes and pro-
longed exposure of skin to cleaning solvent. Wash exposed skin thoroughly. Dry
cleaning solvent used to clean parts is potentially dangerous to personnel and
property. Do not use near open flame or excessive heat. Flash point of solvent
is 100°F. (38°C. to 50°C.). Wear eye protection when blowing solvent from parts.
Compressed air used for cleaning purposes should not exceed 30 PSI (2.1 kg/
cm).
Entry into the tank is prohibited unless the tank has been thoroughly purged,
and the atmosphere has been tested for air contaminants and oxygen deficiency
by technically qualified personnel.
