EXPLOSION The explosion hazard will depend on the solvent used in the formulation.


 
EXPOSURE
STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
INHALATION Convulsions. Dizziness. Laboured breathing. Nausea. Unconsciousness. Vomiting. Pupillary constriction, muscle cramp, excessive salivation.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
SKIN MAY BE ABSORBED! (Further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
EYES Blurred vision.
Face shield, 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 Abdominal cramps. Diarrhoea. Laboured breathing. Nausea. Unconsciousness. Vomiting. Pupillary constriction, muscle cramps, excessive salivation.
Do not eat, drink, or smoke during work.
Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
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. Do NOT wash away into sewer. (extra personal protection: complete protective clothing including self-contained breathing apparatus).
Separated from food and feedstuffs, strong oxidants, strong bases. Dry. Keep in a well-ventilated room.
Do not transport with food and feedstuffs.

PHYSICAL STATE; APPEARANCE:
VISCOUS BROWN LIQUID

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating and on burning producing toxic fumes including phosphorous oxides and sulfur oxides. Hydrolysed by alkalies. Not stable on contact with iron and tin.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: ppm; 0.2 mg/m3 (skin) (ACGIH 1991-1992).


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

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C on spraying.

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Cholinesterase inhibitor; cumulative effect is possible: see acute hazards/symptoms.
PHYSICAL
PROPERTIES
 Melting point: -20°C
Relative density (water = 1): 1.26 at 26°C		 Solubility in water: None
ENVIRONMENTAL
DATA
 This substance may be hazardous to the environment; special attention should be given to crustaceas and fish.
NOTES
Depending on the degree of exposure, periodic medical examination is indicated. The symptoms of acute intoxication do not become manifest until 30 minutes to 2 hours. 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. Delnav, Deltic and Hercules 528 are trade names.
