EXPOSURE
STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
 •INHALATION Pupillary constriction, muscle cramp, excessive salivation. Blurred vision. Sweating. Nausea. Vomiting. Diarrhoea. Abdominal cramps. Dizziness. Convulsions. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention immediately. See Notes.
 •SKIN MAY BE ABSORBED! (Further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Wear protective gloves when administering first aid. Refer immediately for medical attention.
 •EYES Blurred vision.
Face shield, or eye protection in combination with breathing protection.
Rinse with plenty of water (remove contact lenses if easily possible).
 •INGESTION (See Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer immediately for medical attention. See Notes.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes including phosphoric acid and phosphorus oxides. Reacts violently with strong oxidants, causing fire and explosion hazard. Attacks iron, stainless steel, brass, some forms of plastic, rubber

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.01 mg/m as TWA, A4 (not classifiable as a human carcinogen); BEI issued (ACGIH 2008).
MAK: 0.093 mg/m
Peak limitation category: II(2)
(DFG 2008 ).
OSHA PEL: TWA 0.1 mg/m3 skin
NIOSH REL: TWA 0.01 ppm (0.1 mg/m3) ST 0.03 ppm (0.3 mg/m3) skin
NIOSH IDLH: 4 ppm See: 7786347


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
Cholinesterase inhibitor. The substance may cause effects on the nervous system , resulting in convulsions, respiratory failure. Exposure far above OEL may result in death. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
PHYSICAL
PROPERTIES
Decomposes at 300 C
Melting point: (trans) 6.9 C, (cis) 21 C
Relative density (water = 1): 1.25
Solubility in water: miscible
Vapour pressure, Pa at 21C: 0.38
Flash point: 175C o.c.
Octanol/water partition coefficient as log Pow: 1.2
ENVIRONMENTAL
DATA
Environmental Hazard placard The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to birds and This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal.
N O T E S
Depending on the degree of exposure, periodic medical examination is indicated. Consult national legislation. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home.
