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 a 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 affected areas with soap and water.
Seek medical aid. 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.
Ingestion Wash out mouth with water. Do NOT induce vomiting. Give a glass of water. Keep
patient at rest and seek medical advice immediately, 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 Baytex contains fenthion which is an organophosphorus compound, and as such it is a
cholinesterase inhibitor. It also contains xylene as the solvent.
Symptoms of poisoning
Mild intoxication causes headache, blurred vision, weakness, sweating, mild chest pain,
nausea and vomiting. Severe intoxication causes cyanosis (blueness of the skin, as from
lack of oxygen), muscular twitching, spasms, miosis (pinpoint pupils) and respiratory
paralysis.
Treatment
Basic aid, decontamination, symptomatic treatment and if necessary administration of
antidote.
Note for physicians
Antidote: Atropine sulphate, possibly in conjunction with Toxogonin or obidoxime (PAM).
As this product contains the hydrocarbon liquid, xylene, care should be taken to prevent
pulmonary aspiration. Small amounts of liquid aspirated into the respiratory system during
ingestion or from vomiting may cause bronchopneumonia or pulmonary oedema.
Monitor respiratory, cardiac and central nervous system function. Monitor red blood cell
and plasma cholinesterase levels. Administer oxygen if necessary. Watch for pulmonary
oedema and delayed neurological symptoms.
Contraindications: Adrenergic derivatives.
2 regimens for initial atropine treatment are currently suggested, in both cases the
cessation of the cholinergic symptoms salivation, bronchial secretion, sweating and
bradycardia indicates sufficient atropinization. The skin should be dry, the lungs should be
clear on auscultation and the heart rate should be in a range of 80 to 100/minute.
Overdoses of atropine have to be strictly avoided, as these can promote heart rhythm
disturbances.

MATERIAL SAFETY DATA SHEET
Baytex 550 Insecticide
Date of Issue: August 28th 2006
Regimen 1: (2-10 mg atropine i.v. , followed every 15 minutes by 2 mg atropine i.v. until
cessation of the symptoms.
Regimen 2:
- 2 mg atropine i.v., 5 minutes wait, if symptoms persist or reappear
- 4 mg atropine i.v., 5 minutes wait, if symptoms persist or reappear
- 8 mg atropine i.v., 5 minutes wait, if symptoms persist or reappear
- 16 mg atropine i.v., 5 minutes wait, if symptoms persist or reappear
- 32 mg atropine i.v.
No higher doses of atropine should be given nor are necessary.
It is mandatory to allow 5 minutes after each dose for atropine to become fully effective,
the next higher dose must not be given earlier and only if the above symptoms are
persisting. Regimen 2 currently is advisable. If further atropine treatment is required
(taking into account the relatively short effect of carbamates), it should be done by
continuous application of 1 鈥? 2 mg/hour. Atropine treatment can be stopped, when the
plasma cholinesterase level has returned to above 30% of normal.
Survival of patients after severe organophosphorous insecticide poisoning is strongly
dependent on effective intensive care treatment, as aspiration pneumonia and multi-organ
failure are typically the final causes of death in such cases. Thus in severe cases with
cardiorespiratory failure and resuscitation the above regimens, though doubtlessly
effective against the cholinesterase inhibition, may not improve the outcome, because
adequate ICU therapy is critical.
5. FIRE FIGHTING MEASURES
Extinguishing media:
Water fog, foam, carbon dioxide, extinguishing powder
Hazards from
combustion If involved in a fire: sulphur dioxide, phosphorus pentoxide may be emitted.
products:
Precautions for fire The product is a flammable liquid 鈥? flash point 38掳 C. Liquid and vapour of xylene are
fighters: flammable and the vapour will form explosive mixtures with air. The vapour is heavier
than air and may travel along the ground so that distant ignition is a possibility.
Firefighters should wear full protective gear, including self-contained breathing
apparatus (AS/NZS 1715/1716). Keep unnecessary people away and move all other
personnel to windward side of fire. Use water spray to cool fire-exposed containers.
Avoid spraying directly into containers due to danger of boilover. 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. Contamination of water bodies
should be avoided.

6. ACCIDENTAL RELEASE MEASURES
Avoid contact with the spilled material or contaminated surfaces. Extinguish or remove all possible sources of
ignition. 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 and upwind. Prevent spilled material from entering drains or watercourses. Contain spill and absorb with
earth, sand, clay, or other absorbent material. Collect and store in properly labelled drums for safe disposal. Clean
floor with a damp cloth and place cloth in drum. Cover and label drums for safe disposal. Thoroughly ventilate the
area after cleanup. Deal with all spillages immediately. If contamination of drains, streams, watercourses, etc. is
unavoidable, warn the local water authority. Decontaminate tools and equipment used in the cleanup.
