TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.

Foam, powder, carbon dioxide.
EXPLOSION


EXPOSURE
PREVENT GENERATION OF MISTS! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
 •INHALATION Pupillary constriction, muscle cramp, excessive salivation. Sweating. Nausea. Dizziness. Laboured breathing. Convulsions. Unconsciousness.
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 Liquid or aerosol may be absorbed. Redness. Pain. 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 Weakness. Abdominal cramps. Vomiting. Diarrhoea. (Further see Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
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. Personal protection: complete protective clothing including self-contained breathing apparatus.
Separated from food and feedstuffs . Keep in a well-ventilated room.
Do not transport with food and feedstuffs.
Severe marine pollutant.

PHYSICAL STATE; APPEARANCE:
CLEAR COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
Substance is hydrolyzed in contact with strong acids and alkalis.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 mg/m as TWA; (skin); A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2004).
MAK not established.
OSHA PEL: none
NIOSH REL: TWA 0.1 mg/m3 skin
NIOSH IDLH: N.D. See: IDLH INDEX


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

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

EFFECTS OF SHORT-TERM EXPOSURE:
Cholinesterase inhibitor. Exposure above the OEL 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.

ENVIRONMENTAL
DATA
Environmental Hazard placard This substance may be hazardous in the environment; special attention should be given to honey bees and 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.
N O T E S
Depending on the degree of exposure, periodic medical examination is suggested. The symptoms of acute intoxication do not become manifest until some hours have passed. 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. Difonate, Dyfonate 2G, and Stauffer N 2790 are trade names. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response.
