2. HAZARDS IDENTIFICATION


One of the ingredients, pirimiphos-methyl is an organophosphorous insecticide which inhibits cholinesterase
activity, producing both local and systemic effects by interference with nerve transmission. Onset ofsymptoms
may be delayed for several hours. Studies in animals show that repeated exposure produce no significant effects
except for cholinesterase inhibition.
Health Effects from Likely Routes of Exposure:
Ingestion: No adverse health effects are expected from swallowing.
Inhalation: Not harmful.
Test on rats indicate this product is not harmful due to the inhalation of the active ingredient.
Skin Contact: Not harmful.
Test on rats indicate this product is not harmful following skin contact with the active ingredient.
Eye Contact: May cause eye irritation.

_________________________________________________________________________________________
Extinguish small fires with carbon dioxide, dry powder, or alcohol-resistant foam. Contain water used for fire-
fighting for later disposal.
Fire fighting:
Remove spectators from surrounding area. Remove container from fire area if possible. Fight fire from maximum
distance.
Special Hazards:
Fire may produce irritating or poisonous mists (fumes including oxides of carbon, nitrogen and sulphur) or other
products of combustion.
Personal protective equipment:
Fire-fighters and others that may be exposed should wear full protective clothing and self-contained breathing
apparatus.
________________________________________________________________________________________
6. ACCIDENTAL RELEASE MEASURES

Personal precautions:
Ventilate area of spill or leak, especially confined areas. Avoid contact with skin, eyes or clothes. For personal
protection see Section 8.
Environmental precautions:
Do not allow entering drains or watercourses. When the product contaminates public waters, inform appropriate
authorities immediately in accordance with local regulations.
Occupational spill:
For small spills, soak up with sand or suitable non-combustible absorbent material, place into containers for
subsequent disposal. Thoroughly wash body areas, which come into contact with the product. Avoid runoff to
sewer as it may cause fire/explosion. Do not allow the product to come in contact with water systems. For large
spills contact the manufacturer. Contain spillage and contaminated water for subsequent disposal. Do not flush
spilled material into drains.
___________________________________________________________________________________________
7. HANDLING AND STORAGE

Handling:
