O-ethyl-S,S-dipropyl phosphorodithioate Phosphorodithioic acid, O-ethyl S,S-dipropyl ester Ethoprop

CAS #: 13194-48-4

UN #: 3018

EC Number: 236-152-1

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	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.	Use water spray, dry powder, carbon dioxide, alcohol-resistant foam. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.

PREVENT GENERATION OF MISTS! STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Dizziness. Nausea. Sweating. Muscle twitching. Pupillary constriction, muscle cramp, excessive salivation. Laboured breathing. Convulsions. Unconsciousness.	Use 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.	Wear 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 refer for medical attention.
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.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: complete protective clothing including self-contained breathing apparatus. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment.	According to UN GHS Criteria Fatal if swallowed, in contact with skin or if inhaled Causes damage to nervous system Very toxic to aquatic life Transportation UN Classification UN Hazard Class: 6.1; UN Pack Group: I
STORAGE
Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs. Store in an area without drain or sewer access. Ventilation along the floor.
PACKAGING
Do not transport with food and feedstuffs. Marine pollutant.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance PALE YELLOW LIQUID WITH CHARACTERISTIC ODOUR. Physical dangers Chemical dangers Decomposes at room temperature. This produces flammable n-propylmercaptan (see ICSC 1492). Decomposes on heating. This produces toxic fumes including phosphorus oxides and sulfur oxides.	Formula: C₈H₁₉O₂PS₂ Molecular mass: 242.3 Boiling point at 0.03kPa: 86-91°C Melting point: -13°C Relative density (water = 1): 1.09 Solubility in water, g/100ml 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 See Notes. Octanol/water partition coefficient as log Pow: 3.6

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body in hazardous amounts by inhalation, through the skin, through the eyes and by ingestion. Effects of short-term exposure Cholinesterase inhibition. The substance may cause effects on the nervous system. This may result in convulsions and respiratory depression. Exposure could cause death. The effects may be delayed. Medical observation is indicated.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. Effects of long-term or repeated exposure Cholinesterase inhibition. Cumulative effects are possible. See Acute Hazards/Symptoms.

Effects of short-term exposure
Cholinesterase inhibition. The substance may cause effects on the nervous system. This may result in convulsions and respiratory depression. Exposure could cause death. The effects may be delayed. Medical observation is indicated.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

Effects of long-term or repeated exposure
Cholinesterase inhibition. Cumulative effects are possible. See Acute Hazards/Symptoms.

OCCUPATIONAL EXPOSURE LIMITS
TLV BEI issued

ENVIRONMENT
The substance is very toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example 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.
