TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Fire fighters should wear complete protective clothing including self-contained breathing apparatus. Foam, dry powder.
EXPLOSION


EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
 •INHALATION Cough. Shortness of breath. Sore throat.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
 •SKIN Redness. Pain.
Protective gloves.
Rinse and then wash skin with water and soap.
 •EYES Redness. Pain.
Safety goggles or eye protection in combination with breathing protection.
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.
Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Chemical protection suit including self-contained breathing apparatus. Remove all ignition sources. Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place.
Fireproof. Well closed. Keep in a well-ventilated room.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH PUNGENT ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes including phosphorous oxides and phosphine . High concentration of the substance may ignite spontaneously on contact with air.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.05 ppm (Ceiling value) (ACGIH 2001).
OSHA PEL: none
NIOSH REL: C 0.05 ppm (0.25 mg/m3)
NIOSH IDLH: N.D. See: IDLH INDEX


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
See Notes.

EFFECTS OF SHORT-TERM EXPOSURE:
Exposure above the OEL may result in death. The substance is irritating to the respiratory tract , the eyes and the skin .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
PHYSICAL
PROPERTIES
Boiling point: 160C
Relative density (water = 1): 1.00
Solubility in water:
none
Relative vapour density (air = 1): 3.8
Relative density of the vapour/air-mixture at 20C (air = 1): 1.03
Flash point: see Notes
ENVIRONMENTAL
DATA

N O T E S
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. The substance is combustible but no flash point is available in literature. The occupational exposure limit value should not be exceeded during any part of the working exposure.
