| 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. Heating will cause rise in pressure with risk of bursting.
|
NO open flames.
|
Water spray, dry powder, carbon dioxide, alcohol-resistant foam.
|
| EXPLOSION |
|
|
In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water.
|
| EXPOSURE |
|
PREVENT GENERATION OF MISTS! STRICT HYGIENE!
|
IN ALL CASES CONSULT A DOCTOR!
|
| Inhalation |
Dizziness. Nausea. Sweating. Muscle twitching. Pupillary constriction, muscle cramp, excessive salivation. Laboured breathing. Convulsions. Unconsciousness.
|
Local exhaust or breathing protection.
|
Fresh air, rest. Artificial respiration may be needed. Refer immediately for medical attention.
|
| Skin |
MAY BE ABSORBED! (See Inhalation).
|
Protective gloves. Protective clothing.
|
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer immediately for medical attention. Wear protective gloves when administering first aid.
|
| Eyes |
MAY BE ABSORBED! 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. Vomiting. (Further 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.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: PALE YELLOW LIQUID, WITH CHARACTERISTIC ODOUR. CHEMICAL DANGERS: The substance decomposes at room temperature producing flammable n-Propylmercaptan (see ICSC 1492), and on heating producing toxic fumes including phosphorus oxides and sulfur oxides. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. |
ROUTES OF EXPOSURE: The substance can be absorbed into the body in hazardous amounts by inhalation, through the skin, eyes and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: Cholinesterase inhibition. The substance may cause effects on the nervous system , resulting in convulsions and respiratory depression. Exposure may result in death. The effects may be delayed. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Cholinesterase inhibitor; cumulative effect is possible: see acute hazards/symptoms. | ||

Boiling point at 0.03kPa: 86-91°C Melting point: -13°C Relative density (water = 1): 1.09 Solubility in water, g/100 ml at 20°C: 0.075 Vapour pressure, Pa at 20-25°C: 0.05 Relative vapour density (air = 1): 8.4 |
Flash point: see Notes Octanol/water partition coefficient as log Pow: 3.6 | ||
| ENVIRONMENTAL DATA | |||
|
The substance is very toxic to aquatic organisms. 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.
| |||
| NOTES | |||
|
Do NOT take working clothes home. The substance is combustible but no flash point is available in literature. Depending on the degree of exposure, periodic medical examination is suggested. 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.
