Emergency Overview This product is of low oral toxicity and under normal conditions of use should present no significant health hazards. However, handling precautions should be strictly observed.
Health Rating: 1 – slight
Flammability Rating: 1 – slight
Reactivity Rating: 1 – slight (Incompatible with strong oxidizers)
Environment Rating: 3 – none

Skin Contact: Immediately wash contaminated skin with plenty of water followed by soap and water. Remove contaminated clothing and wash before reuse.
If redness, itching, or a burning sensation develops, get medical attention. Seek medical attention if irritation develops or persists.
Eye Contact: Rinse immediately with plenty of water until irritation subsides. After initial flushing, remove any contact lenses and continue flushing for at least 15 minutes. If irritation persists, obtain medical advice. Have eyes examined and treated by medical personnel.
Ingestion: Rinse mouth with water. If swallowed, do not induce vomiting since it is important that no amount of the material should enter the lungs (aspiration). Contact physician, Poison Center or emergency clinic
before inducing vomiting. Keep at rest. Do not induce vomiting or give anything by mouth to an unconscious person. Get prompt medical attention.
Inhalation: Remove victim from exposure. Provide fresh air. Remove contaminated clothing and loosen remaining clothing. Allow patient to assume most comfortable position and keep warm. Seek medical advice.
Notice to physician: Treat symptomatically. For the active constituent metaldehyde: Effects may be delayed. Remove metaldehyde by gastric lavage with a 2-5% sodium bicarbonate solution and activated charcoal, effective up to 12-24 hours after swallowing if necessary administration of antidote - Atropine sulphate (contra-indication: oxime therapy). The ingestion of large quantities may present anti-cholinesterase effects.

Extinguishing media: Foam, dry chemical powder, carbon dioxide, water fog. (Water runoff should be contained)
Special firefighting procedures: Combustible solid. On burning will emit toxic fumes. Respiratory and eye protection required for fire fighting personnel exposed to products of combustion or decomposition.
Fire and Explosion Hazards: Combustible solid. In common with many organic chemicals, may form flammable dust clouds in air.
Hazardous Combustion Products: Smoke, carbon monoxide, carbon dioxide, oxides of nitrogen, methylamine, and small amounts of methyl isocyanate.

Spill: Make sure all personnel involved in the spill cleanup follow good industrial hygiene practices. A small spill can be handled routinely. Use adequate ventilation and wear respirator to prevent inhalation. Wear suitable protective clothing and eye protection to prevent skin and eye contact. Use the following procedure:

  1. Sweep up or vacuum, with an appropriate vacuum cleaner, spilled material, being careful not to create dust, and shovel sweepings into an open drum.
  2. Generously cover the contaminated areas with common, household detergent. Using a stiff brush and small amounts of water, work the detergent into the remaining spilled material forming a slurry. Brush the slurry into cracks and crevices and allow to stand for 2-3 minutes. Be careful to completely avoid skin and eye contact. Do not splatter on oneself or bystanders.
  3. Spread absorbents on the slurry liquid and shovel mixture into the  open drum.
  4. Repeat #2 and 3 if necessary.
  5. If practical, flush the area with water to a sewer serviced by a wastewater treatment facility.
  6. Seal drum and dispose of contaminated waste in a landfill permitted for hazardous waste.
  7. Large spills should be handled according to a spill plan. In emergency contact the manufacturer.
  8. If contamination of waterways has occurred, advise emergency services.

Precautions to be taken in handling and storage:
Storage: Store the product in locked, cool, dry, well-ventilated surroundings, well away from sources of ignition. Keep away from children and away from foodstuffs, oxidizing agents and strong bases, or stockfeed. Toxic to fish and wildlife. Keep container closed when not in use. Take extreme care to avoid contamination by other products and materials.
Suitable container materials: LDPE (low density polyethylene).

Occupational Exposure Limit: 5mg/m3 (TWA, 8hr – workday)
Personal Protection: In open systems where contact is likely, wear safety goggles, chemical resistant overalls and chemically impervious gloves.
Where only incidental contact is likely, wear safety glasses with side shields. No other special precautions are necessary provided skin/eye contact is avoided. When concentrations in air may exceed the occupational exposure limit and where engineering, work practices or other means of exposure reduction are not adequate, local exhaust ventilation is recommended although approved respirators may be used.
Personal Protective Equipment: Overalls, safety shoes, safety glasses and glove(s). Always follow good industrial hygiene practices. Wash hands before smoking, eating, drinking or using the toilet. If risk of inhalation of dust, wear suitable respirator to prevent inhalation.

Appearance and odour: Blue pellets.
Solubility in water: Medium
pH Not: applicable
Boiling point: Unknown
Density at 15 Deg. C: Unknown

Stability: Stable
Incompatibility: Avoid contact with strong oxidants, strong bases and concentrated oxygen.
Hazardous Decomposition Products: Product does not decompose at ambient temperature.
Conditions to Avoid: Keep away from heat sources, open flames and other sources of ignition.

Effects of Overexposure: Inhalation: Avoid breathing dusts. Negligible hazard at ambient/normal handling temperatures, when using personal protective equipment. Mechanical action may form dust, which may be irritating to the eyes, nose, throat and lungs.
Skin: Prolonged or repeated contact may lead to skin irritation and poisoning.
Eye: Irritating, and may injure eye tissue.
Ingestion: Swallowing can result in nausea, abdominal pain and in severe cases of poisoning, convulsions.
Minute amounts aspirated into the lungs during ingestion or vomiting may cause medical problems.
Chronic: No LD50 data available for this product. The components in the proportions present are not considered to represent a hazard under conditions of good occupational work practice.
For the active constituent Metaldehyde:
Oral: LD50 (rat): 283mg/kg.
Dermal: LD50 (rat) 2275mg/kg.
Inhalation: LC50 (rat): 203mg/m3/4hrs.
Skin: (rabbit): Non-irritant.
Eye: (rabbit): Slight irritant.
For the active constituent Methiocarb:
Oral LD50 (rat): >4000mg/kg.
Dermal LD50 (rabbit) >4000mg/kg.
Acute Effects: No test data are available for this product. The potential health hazards were therefore derived from what is known of the toxicity of the ingredients in general.
Chronic Effects - Methiocarb: No effect level rat (24 months) 200 mg/kg, dog (12 months) 60mg/kg (methiocarb).

Aquatic toxicity – fish:
LC50 (methiocarb): 0,44-4,7 mg/l (96 h) rainbow trout.
(Oncorhynchus mykiss); 3,8 mg/l (96 h) golden orfe (leuciscus idus).
0,75 mg/l (96 h) bluegill (Lepomis macrochirus).
Metaldehyde: rainbow trout 75 mg/l.
Aquatic toxicity – Daphnia:
LC50 : 0,019 mg/l (48 h); Water flea (Daphnia magna) – methiocarb. >90 mg/l (48 h) – metaldehyde.
Aquatic toxicity – Algae:
IC50 : 1,15 mg/l (96 h) (Scenedesmus subspicatus) – methiocarb; 73,5mg/l - metaldehyde.
Biodegradability: Rapidly degraded in the soil. In dogs and mice methiocarb is rapidly absorbed and excreted, principally in the urine and a small proportion in the faeces.
Bio-accumulation: None.
