(207 kPa) or injury to personnel may result.
Dry cleaning solvent (P-D-680, Type III) is used to clean parts and is potentially
dangerous to personnel and property. Extinguish all smoking materials and do not
allow sparks or open flames near the work area. Use skin and eye protection and
work in a well-ventilated area. Flash point of dry cleaning solvent is 200F (93C).
