IV. FIRE AND EXPLOSION HAZARD DATA
FLASH POINT: 101 ˚F (for a 25% solution)
(METHOD USED): Closed Cup
FLAMMABLE LIMITS: LEL=6%
UEL=36%
EXTINGUISHING MEDIA: Alcohol foam, carbon dioxide, dry chemi-
cal, or water fog.
SPECIAL FIRE FIGHTING PROCEDURES: Fire fighters should
wear full protective clothing and self-contained breathing apparatus with
full facepiece. Use water to keep fire-exposed containers cool.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Vapor is heavier
than air and may travel along the ground. Never use a welding or cutting
torch near container (even empty). This material may burn with a flame
which is invisible in daylight.
V. HEALTH HAZARD INFORMATION
SYMPTOMS OF OVEREXPOSURE (for each potential route of expo-
sure):
INHALED: Excessive inhalation can cause nasal and respiratory irrita-
tion, visual disturbance, blurred vision, dizziness, giddiness, weakness,
fatigue, nausea, vomiting, headache, possible unconsciousness, and
asphyxiation.
