TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Extremely flammable.
NO open flames, NO sparks, and NO smoking.
Powder, AFFF, foam, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

Inhalation
Ventilation.
Fresh air, rest.
Skin Dry skin. Redness.
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Evacuate danger area! Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Personal protection: filter respirator for organic gases and vapours.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (Octanes) 300 ppm as TWA; (ACGIH 2005).
MAK: (Octanes) 500 ppm, 2400 mg/m; Peak limitation category: II(2); Pregnancy risk group: IIc; (DFG 2005).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the skin.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin.
