4. FIRST AID MEASURES
If poisoning occurs, immediately contact a doctor or Poisons Information Centre (telephone 13 11 26),
and follow the advice given. Show this Material Safety Data Sheet to the doctor.
Inhalation If inhaled, remove to fresh air and keep at rest. Obtain medical advice. If breathing stops
or shows signs of failing, start artificial respiration. If advised by doctor or Poisons
Information Centre, atropine tablets may be administered.
Skin contact Immediately remove contaminated clothing. Wash skin with soap and water. Seek
medical attention if irritation develops or persists. If signs of poisoning occur get medical
attention immediately. Persons assisting the patient should protect themselves from
contamination. If advised by doctor or Poisons Information Centre, atropine tablets may
be administered.
Eye contact Rinse eyes immediately with clean water for at least 15 minutes and obtain medical aid,
preferably from an eye specialist.
Ingestion Wash out mouth with water. Keep patient at rest and seek urgent medical advice as
above. Transport patient to doctor or hospital quickly. If advised by doctor or Poisons
Information Centre, atropine tablets may be administered.
DO NOT attempt to give anything by mouth to a semi-conscious or unconscious person.
First Aid Facilities Provide eyewash and safety shower facilities in the workplace.
Obtain an emergency supply of atropine tablets 0.6 mg.
Medical attention Mesurol Snail and Slug Bait contains methiocarb, which is a carbamate insecticide, and
as such it is a cholinesterase inhibitor.
Symptoms of poisoning
Mild intoxication causes headache, blurred vision, weakness, sweating, mild chest pain,
nausea and vomiting. Severe intoxication causes cyanosis, muscular twitching, spasms,
miosis and respiratory paralysis.
Onset of symptoms may be delayed. Cholinesterase inhibition sometimes persists for
several weeks.
Treatment
Basic aid, decontamination, symptomatic treatment and if necessary administration of
antidote.
Antidote: Atropine sulphate. Atropine should not be given to a cyanosed patient.
Oximes are contraindicated. Monitor respiratory, cardiac and central nervous system
functions. Monitor red blood cell and plasma cholinesterase levels. Administer oxygen if
necessary. Watch for pulmonary oedema and delayed neurological symptoms.
Contraindications
Adrenergic derivatives. Never give patient morphine, theophylline or theophylline-
ethylenediamine. Large amounts of intravenous fluids are generally contraindicated
because of the threat of pulmonary oedema.
Veterinary Dogs find this bait attractive and if ingested it may kill them. If a dog eats pellets take it to
a veterinarian immediately. Do not give dogs Ipecac Syrup.

5. FIRE FIGHTING MEASURES
Extinguishing media Waterspray, foam, dry chemical, carbon dioxide, sand.
Hazards from In a fire, hydrogen cyanide, carbon monoxide, methyl isocyanate, sulphur dioxide and
combustion products nitrogen oxides may be formed.
Precautions for fire Fire fighters should wear full protective gear, including self-contained breathing
fighters apparatus (AS/NZS 1715/1716). Keep unnecessary people away and move all other
personnel to windward side of fire. Bund area with sand or earth to prevent
contamination of drains or waterways. Dispose of fire control water or other
extinguishing agent and spillage safely later.
Hazchem code Not applicable
6. ACCIDENTAL RELEASE MEASURES
Avoid contact with the spilled material or contaminated surfaces. Do not smoke, eat or drink during the cleanup
process. Personnel involved in cleanup should wear protective clothing and equipment as described in Section 8
?PERSONAL PROTECTION. Keep people and animals away. Prevent spilled material from entering drains or
watercourses. Contain spill and sweep up carefully. Avoid creating dust. Collect and store in recovery drums.
Clean floor with a damp cloth and place it in the recovery drum. Seal and label drums for safe disposal. Deal
with all spillages immediately. If contamination of drains, streams, watercourses, etc. is unavoidable, warn the
local water authority.
7. HANDLING AND STORAGE
Handling Keep out of reach of children. Product is poisonous if swallowed. Avoid contact with
eyes and skin. If product on skin immediately wash area with soap and water. After
use and before eating, drinking or smoking, wash hands, arms and face thoroughly with
soap and water.
After filling applicator, clean up spilled pellets so that they are not eaten by animals and
birds.
Storage Store in the closed, original container in a dry, cool, well-ventilated, secure area out of
direct sunlight. Lock in a safe place preventing access of children, animals, poultry or
ducks. Keep away from domestic pets.
Flammability Not readily combustible.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Exposure standards There is no NOHSC Exposure standard for methiocarb.
The National Occupational Health and Safety Commission (NOHSC) exposure
standards:
TWA calcium sulphate: 10 mg/m?(as inspirable dust)
TWA butylated hydroxy toluene: 10 mg/m3.
Definitions:
Exposure standard ?Time Weighted Average (TWA) means the average airborne
concentration of a particular substance when calculated over a normal eight-hour
working day, for a five-day working week.

11. TOXICOLOGICAL INFORMATION
POTENTIAL HEALTH EFFECTS
Methiocarb, the active ingredient in Mesurol Snail and Slug Bait, is a carbamate pesticide which is a
cholinesterase inhibitor. Symptoms typical of cholinesterase inhibition (for all routes of entry):
Mild cases
Headache, blurred vision, weakness, sweating, mild chest pain, nausea and vomiting.
Severe cases
Cyanosis (blueness of the skin, as from lack of oxygen), muscular twitching, spasms, miosis (pinpoint pupils) and
respiratory paralysis. These symptoms commence from one to three hours after excessive exposure.
Dogs find this bait attractive and if ingested it may kill them.
Inhalation Methiocarb is very poisonous by inhalation. Inhalation of the bait pellets containing 2%
methiocarb is unlikely, unless dust is created.
Skin contact Poisonous if absorbed by skin contact, but this route of exposure is unlikely. Not
expected to irritate the skin.
Eye contact May irritate the eyes.
Ingestion Harmful if swallowed.
ANIMAL TOXICITY DATA - PRODUCT
Acute:
Oral toxicity LD50 rat: > 500 to < 1000 mg/kg
Dermal toxicity LD50 rat: > 2000 mg/kg
Inhalation toxicity LC50 (4 h) rat: > 0.224 mg/L ?dustable powder ?highest producible concentration
Skin irritation Non irritant (rabbit)
Irritation to mucous Non irritant (rabbit)
membranes
Sensitisation Not a skin sensitiser.
Chronic:
The main health effects from repeated exposure would be toxic symptoms of cholinesterase inhibition as
described above. Methiocarb showed no evidence of oncogenic or carcinogenic potential in animal studies.
Methiocarb is not mutagenic, and has shown no teratogenic effects in animal studies. It does not cause delayed
neurotoxicity. In the USA methiocarb is considered to be a developmental toxicant.
12. ECOLOGICAL INFORMATION
Very toxic to aquatic organisms. This product is dangerous to game, wild birds and animals. Methiocarb has a
repellent effect on birds. DO NOT contaminate streams, rivers or waterways with Mesurol Snail and Slug Bait or
the used containers.
