EXPOSURE
AVOID ALL CONTACT! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Sweating. Pupillary constriction, muscle cramp, excessive salivation. Dizziness. Laboured breathing. Nausea. Vomiting. Convulsions. Unconsciousness.
Ventilation (not if powder), local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. See Notes.
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. See Notes.
Eyes

ALDICARB ICSC: 0094
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS.

CHEMICAL DANGERS:
On combustion, forms toxic fumes including nitrogen oxides, sulfur oxides.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established. MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, 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, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the nervous system, resulting in convulsions and respiratory depression. Cholinesterase inhibitor. Exposure may result in death. The effects may be delayed. Medical observation is indicated.

PHYSICAL PROPERTIES
Decomposes below boiling point: see Notes
Melting point: 100°C
Solubility in water, g/100 ml at 25°C: 0.6
Vapour pressure, Pa at 25°C: 0.01
Octanol/water partition coefficient as log Pow: 1.36
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to birds, honey bees, mammals, soil organisms, water quality. 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
Temperature of decomposition unknown in literature. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Do NOT take working clothes home.
