| IMPORTANT DATA | |||
| PHYSICAL
STATE; APPEARANCE: YELLOW TO BROWN CRYSTALLINE POWDER, WITH CHARACTERISTIC ODOUR. CHEMICAL DANGERS: The substance decomposes on heating producing toxic and corrosive fumes including nitrogen oxides, phosphorous oxides, sulfur oxides. Reacts with oxidants. The substance decomposes under influence of alkalies (hydrolysis) forming p-nitrophenol (see ICSC 0066). OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.1 mg/m^3 (as TWA) (skin) (ACGIH 1997). MAK: 0.5 mg/m^3; III, H (1996). |
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 be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. EFFECTS OF SHORT-TERM EXPOSURE: The substance may cause effects on the nervous system, resulting in convulsions, respiratory failure. Cholinesterase inhibitor. Exposure may result in unconsciousness or 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 | |||
| The substance is very toxic to aquatic organisms. This substance
may be hazardous to the environment; special attention should be given to
honey bees. Avoid release to the environment in circumstances different to
normal use. | |||
| 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 1-2 hours. 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. | |||
