| 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. |
NO open
flames. |
Powder,
water spray, foam, carbon dioxide. |
| EXPLOSION | Risk of fire
and explosion if formulations contain flammable/explosive solvents.
|
| 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.
Vomiting. Abdominal cramps. Diarrhoea. Unconsciousness. Dizziness.
Laboured breathing. Weakness. |
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 | Pupillary
constriction. 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 | Convulsions.
(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. Induce vomiting
(ONLY IN CONSCIOUS PERSONS!). Rest. Refer for medical attention.
|
| SPILLAGE DISPOSAL | 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: chemical
protection suit including self-contained breathing apparatus).

| IMPORTANT DATA | |||
| PHYSICAL
STATE; APPEARANCE: COLOURLESS TO PALE YELLOW OILY LIQUID, WITH CHARACTERISTIC ODOUR. CHEMICAL DANGERS: The substance decomposes on heating and on burning producing toxic fumes including phosphorous oxides, sulfur oxides. |
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 will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing much faster. EFFECTS OF SHORT-TERM EXPOSURE: The substance may cause effects on the nervous system, resulting in convulsions, respiratory failure and death. Cholinesterase inhibitor. 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 | |||
| The substance is toxic to aquatic organisms. This substance may be
hazardous to the environment; special attention should be given to honey
bees, mammals, birds. Avoid release to the environment in circumstances
different to normal use. | |||
| NOTES | |||
| Depending on the degree of exposure, periodic medical examination
is indicated. Specific treatment is necessary in case of poisoning with
this substance; the appropriate means with instructions must be available.
If the substance is formulated with solvent(s) also consult the card(s)
(ICSC) of the solvent(s). Carrier solvents used in commercial formulations
may change physical and toxicological properties. Do NOT take working
clothes home. Azotox, Demetox, Duratox, Metasystox i, Metasystox 55,
Mifatox, Persyst are trade names. Also consult ICSC # 0429
(Demeton-O-methyl). | |||
