SECTION 2 - COMPOSITION, INFORMATION ON INGREDIENTS
SECTION 3 - IDENTIFICATION OF HAZARDS
- Cholinesterase inhibitor.
- Harmful if swallowed.
- Harmful if absorbed through skin or inhaled.
- Causes slight eye irritation.
- Avoid breathing product vapors or spray mist.
- Avoid contact with eyes, skin or clothing.
- Keep out of reach of children.
Symptoms of over exposure are headaches, nausea, vomiting, cramps, weakness, blurred
vision, pin point pupils, tightness in chest, labored breathing, nervousness, sweating, watering
of eyes, drooling, muscle spasms and coma.
Potential Health Hazards:
EYE CONTACT: May cause eye injury.
SKIN CONTACT: Irritation may occur. The most likely rout of entry.
INGESTION: Contact a physician if material is ingested.
INHALATION: Contact a physician if material is inhaled and breathing is difficult.
Signs and symptoms of short-term (acute) exposure:
INHALATION: Malathion is a cholinesterase inhibitor of low mammalian toxicity. However
storage at too high temperatures may induce formation of the much more toxic and synergistic
contaminant isomalathion. Malathion and isomalathion can affect you when breathed in and
can cause organophosphorous poisoning. Symptoms of poisoning may include headache,
nausea, vomiting, blurred vision, tightness in chest, drooling, frothing of mouth and nose,
convulsions, coma and death.
SKIN CONTACT: Direct skin contact may causes irritation. Malathion and isomalathion can
be rapidly absorbed through all skin surfaces. Causes symptoms similar to those listed for
EYE CONTACT: Direct eye contact causes irritation. Malathion and isomalathion can be
rapidly absorbed through all skin and eye surfaces. Causes symptoms similar to those listed for
INGESTION: Malathion and isomalathion are poisons through ingestion. Causes symptoms
similar to those listed for inhalation.
Effects of long-term (chronic) exposure: Prolonged or repeated overexposure may cause
behavioural changes. Carcinogcnicity: See TOX1COLOGICAL INFORMATION.
SECTION 4- FIRST AID MEASURES
INHALATION: Immediately remove victim to fresh air. If breathing has stopped, begin
artificial respiration immediately. Transport to a clinic or hospital immediately.
SKIN: Immediately flush skin with running water for at least 15 minutes, while removing
contaminated clothing and shoes. Obtain medical attention immediately. Thoroughly clean
contaminated clothing before re-use.
EYES: Immediately flush eyes with running water for at least 15 minutes. Get medical attention
INGESTION: If ingested, have victims drunk 6 to 8 ounces of water. Induce vomiting
immediately only under the direct supervision of qualified medical personnel. Never give
anything by mouth if victim is unconscious or convulsing. Transport to a clinic or hospital
NOTE TO PHYSICIAN: Malathion is a cholinesterase inhibitor affecting the central and
peripheral nervous systems and producing respiratory and cardiac depression. Decontamination
procedures such as whole body washing, gastric lavage and administration of activated charcoal
are often required. If symptoms are present, administer atropine sulphate in large doses. Two to
four mg intravenously or intramuscularly as soon as possible. Repeat at 5 to 10 minute’s
intervals until signs of atropinization appear and maintain full atropinization until all
organophosphorous is metabolised. Obidoxime chloride (Toxogonin), alternatively pralidoxime
chloride (2-PAM), is a pharmacological antidote and may be administered as an adjunct to, but
not a substitute for atropine, which is a symptomatic and often life-saving antidote. At first sign
of pulmonary edema, the patient should be given supplemental oxygen and treated
symptomatically. Continued absorption of Malathion may occur and relapse may occiu" after
initial improvement. VERY CLOSE SUPERVISION OF THE PATIENT IS INDICATED FOR
AT LEAST 48 HOURS.
SECTION 5 - FIRE FIGHTING MEASURES
FLASHPOINT: 163 oC (Pensky-Martens closed cup)
FLAMMABLE LIMITS: lower -1, upper -7
FIRE AND EXPLOSION HAZARD: Alert medical personnel to be ready to treat for
pesticide poisoning, should treatment be necessary
EXTINGUISHING MEDIA: Dry chemical or carbon dioxide for small fires. Water spray or
foam for large fires.
Special fire fighting procedure: wear self-contained breathing apparatus and full fire fighting
clothing. Use as little water as possible. Dike area to prevent pesticide runoff. Use spray or fog.

SECTION 6 - ACCIDENTAL RELEASE MEASURES
PERSONAL PRECAUTIONS: Restrict access to area until completion of clean up. Ensure
clean-trained personnel conduct up only. All persons dealing with clean up should wear the
appropriate chemically protective equipment. Refer to Section 8, EXPOSURE CONTROLS
AND PERSONAL PROTECTION, for additional information on acceptable personal
ENVIRONMENTAL PRECAUTIONS: Ensure spilled product does not enter drains, sewers,
waterways, or confined spaces.
Dike far ahead of the spill for later recovery or disposal. Washings must be prevented from
entering surface water drains. Uncontrolled discharge into watercourses must be alerted to the
appropriate regulatory body.
SPILL RESPONSE/CLEANUP: Eliminate all sources of heat, sparks and flame. Ventilate
area of release. Stop leak if you can do so without risk. Notify the appropriate authorities. For
spills on the floor or other impervious surfaces, absorb spill with inert, non-combustible
absorbent material, such as hydrated lime. Fuller's earth or other absorbent clays. Scoop up and
place contaminated absorbent material into suitable containers for later disposal. Rinse spills
area with soda lye. Do not flush to sewer or allow entering confined spaces. Large spills that
soak into the ground should be dug up, placed in suitable containers and disposed of
appropriately. Notify the appropriate authorities.
PROHIBITED MATERIALS: None known.
SECTION 7 - HANDLING AND STORAGE
HANDLING: keep out of reach of children. Very dangerous. Poisonous if absorbed by skin
contact, inhaled or swallowed. Avoid contact with eyes and skin. Do not touch or rub eyes, nose
or mouth with hand when handling granules. Wear protective clothing and equipment as above.
Keep away from volatile chemicals and sources of ignition.
If product on skin, immediately wash area with soap and water. After use and before eating,
drinking or smoking washes hands, arms and face thoroughly with soap and water. After each
day’s use, wash gloves respirator and contaminated clothing with detergent and warm water.
