Ingredients                                                                                                   

This is a commercial product whose exact ratio of components may vary. Trace quantities of impurities are also likely.

Health Effects:

Regular exposure may result in the lowering of cholinesterase activity. No other adverse effects have been noted in populations regularly using the product. No data for this formulation. At doses toxic to maternal animals, carbaryl has been shown to produce developmental toxicity in a number of species. No such effects have been observed in the absence of maternal toxicity. The balance of evidence supports the conclusion that carbaryl and its metabolites do not present a quantifiable mutagenic risk to humans. Carcinogenicity studies in animals have been shown to be negative.

Acute Effects:

Symptoms of acute over-exposure to large quantities of product: rapid onset of nausea, vomiting, abdominal pains , diarrhoea, pinpoint pupils, blurred vision, profuse sweating, salivation, muscle twitching and temporary paralysis. More severe poisoning may depress respiration and convulsions may occur. Usually recovery is rapid.
Swallowed: Unlikely route of exposure of the solid product. The product is toxic if swallowed and will present a moderate to severe hazard. Swallowing of large quantities could lead to respiratory depression and possibly convulsions. Depending on quantity swallowed death could occur. The concentrate is considered harmful by swallowing, when classified according to the Worksafe criteria.
Eye: This product may irritate eyes. However, it is unlikely to cause any more than mild transient discomfort. It is also unlikely to cause any significant lasting effects.
Skin: Data suggests that this product may be absorbed through the skin and be harmful by skin absorption. Major skin exposure may lead to health problems.
Inhalation: Data suggests that this product is harmful if inhaled. Minor or short term exposure may lead to short term health problems, although long term exposure may lead to permanent health problems.
LD₅₀ Oral (Rat) = 850mg/kg (G), 500mg/kg (E)                    LD₅₀ Dermal (Rat) = 4000mg/kg
LC₅₀ Inhalation (Rat) = 2.5mg/L/4hr                                  
In 2 years feeding trials, rats receiving 200 mg/Kg diet suffered no ill effects. No occupational deaths have been recorded for Carbaryl in many years of use, nor have there been any reported accidental deaths. There has been only one reported death to our knowledge - a suicide.
Toxicity to fish: LC₅₀ to fish is 5- 13 mg/L; moderately toxic. Carbaryl is toxic to bees.

First Aid:

Ipecac Syrup APF should be available in the area where product is used, or in a nearby unlocked medicine cabinet.
Atropine tablets 0.6mg should be available in the area where this product is used, or in a nearby unlocked medicine cabinet. Safety deluge showers should be provided where this product is being used.
If poisoning occurs, contact a Doctor or Poisons Information Centre. Phone 13 1126 from anywhere in Australia.
If swallowed, give one atropine tablet every 5 minutes until dryness of the mouth occurs - if poisoned by skin absorption or through lungs, remove any contaminated clothing, wash skin thoroughly and give atropine tablets as above. Get to a doctor or hospital quickly.
Eyes: If product gets in eyes, wash material from them with running water. If they begin watering or reddening, take special care in washing thoroughly.
Skin: If product gets on skin, immediately remove contaminated clothing and wash skin thoroughly with soap and water to remove material. If you begin to feel unwell, seek medical attention.
Inhalation: If vapours of dusts have been inhaled, and irritation or unusual symptoms have developed, remove to fresh air and observe until recovered. If irritation or symptoms persists more than 30 minutes, seek medical advice.
Advice to Doctor: The product is a carbamate, a cholinesterase inhibitor. The effects of overexposure are reversible. Treat symptomatically. Atropine treatment may be required, or treat with up to 10 mg diazepam; curare therapy is contra-indicated. Do not give adrenergic amines, aminophylline, succinylcholine, phenothiazines or reserpine alkaloids or oils. Caution should be maintained to prevent over-atropinisation. Persons regularly exposed to this product should have a pre-exposure and periodic red blood cell cholinesterase level check. (Check appropriate State regulations).

Risk Phrases are: R20, R21, R25. Harmful by inhalation. Harmful in contact with skin. Toxic if swallowed.

Exposure Standards:

A time weighted average (TWA) has been established for Carbaryl, present in significant quantities in this product. This value is 5mg/m³. The corresponding STEL level is "not set". The STEL (Short Term Exposure Limit) is an exposure value that should not be exceeded for more than 15 minutes and should not be repeated for more than 4 times per day. There should be at least 60 minutes between successive exposures at the STEL. The exposure value at the TWA is the average airborne concentration of a particular substance when calculated over a normal 8 hour working day for a 5 day working week. See ingredients section on page 1 of this data sheet. The ADI (Acceptable Daily Intake) for Carbaryl is set at 0.01mg/kg/day. The corresponding NOEL (No-observable-effect-level) is set at 2mg/kg/day. Values taken from Australian ADI List, May 1995.

Engineering Controls:

In industrial situations, concentration values below the TWA value should be maintained. Values may be reduced by process modification, use of local exhaust ventilation, capturing substances at the source, or other methods. If you believe air borne concentrations of mists, dusts or vapours are high, you are advised to modify the process or environment to reduce the problem.

Personal Protection:

Avoid exposure by inhalation. Do not swallow product. Avoid getting product on skin, in eyes or on clothing. Wear long sleeved body covering clothing buttoned at the neck and at the wrists. When handling the product, wear elbow length PVC gloves and eye protection. Avoid generating dusts. Wear an approved air purifying dust respirator suitable for pesticides when handling the dry product. If product gets on skin, wash off immediately with water and soap. Remove contaminated clothing. Wash clothing before re-use. After handling and using the product and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water. After each day's use wash gloves, safety gear and protective clothing.

Safety Phrases are: S20, S24, S38. When using, do not eat or drink. Avoid contact with skin. In case of insufficient ventilation, wear suitable respiratory equipment.
