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 symptoms are
experienced. If breathing stops or shows signs of failing, start artificial respiration. Call for
prompt medical attention.
Skin contact Carefully remove contaminated clothing. Wash affected areas with soap and water. Seek
medical aid if at all worried.
Eye contact Rinse eyes immediately with clean water for at least 15 minutes and obtain medical aid.
Seek eye treatment from an ophthalmologist.
Ingestion Wash out mouth with water. Do NOT induce vomiting. Give a glass of water. Keep patient at
rest and seek medical advice as above. 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.
Medical attention Local: Irritation of eyes and respiratory tract. Skin dryness or cracking from repeated exposure.
Potential skin sensitisation.
Systemic: Headache, dizziness, drowsiness, nausea, confusion, anaesthesia and other central
nervous system effects. May cause lung damage if swallowed, with symptoms including cough,
tachypnoea (rapid breathing), breathlessness, cyanosis (blueness of the skin) and fever.
Treatment
For local contamination treatment should be symptomatic after decontamination. In case of
skin or eye contamination, treat as above under First Aid Measures.
Note for physicians
As this product contains a hydrocarbon liquid, 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.
Due to the low oral toxicity, and the risk of aspiration into the lung, gastric lavage is not
recommended. In case of ingestion of large amounts, it may be considered after adequate
airway protection (intubation with block), as the risk of spontaneous vomiting with aspiration
might be higher. Activated charcoal and cathartics (magnesium or sodium) should be given.
Treatment should be supportive and symptomatic. In case of acute respiratory distress
syndrome, the use of PEEP-ventilation has been suggested. Monitor kidney, liver and pancreas
function.
Contraindications: Catecholamines should be avoided due to an increased risk of ventricular
fibrillation.

5. FIRE FIGHTING MEASURES
Extinguishing media Water spray, foam, carbon dioxide, dry agent.
Hazards from In a fire, formation of hydrogen chloride, cyanides, and oxides of carbon, nitrogen and sulphur
combustion products can be expected.
Precautions for fire The product is a Class 1 Combustible Liquid. Firefighters should wear full protective gear,
fighters including self-contained breathing apparatus (AS/NZS 1715/1716). If possible and without risk,
remove intact containers from exposure to fire. Otherwise, spray unopened containers with
water to keep cool. Avoid spraying directly into containers due to danger of boilover. Contain
fire-fighting water by bunding area with sand or earth to prevent it entering any bodies of water.
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. Extinguish all possible sources of ignition. When dealing
with spills do not eat, drink or smoke and wear personal protective clothing and equipment as described in Section 8 -
PERSONAL PROTECTION. 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, sealed 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.
7. HANDLING AND STORAGE
Handling Keep out of reach of children. Will damage the eyes. Will irritate the skin. Avoid contact with
eyes and skin. Do not inhale vapour. If product on skin, immediately wash area with soap and
water. If product in eyes, wash it out immediately with water. After handling and before eating,
drinking or smoking, wash hands, arms and face thoroughly with soap and water. After each
day's use, wash gloves, goggles or face-shield and contaminated clothing. Keep product away
from sources of ignition.
Storage Store in the closed, original container in a cool, well-ventilated area. Do not store for prolonged
periods in direct sunlight. Keep away from ignition sources and protect from extreme heat.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Exposure standards The manufacturer of the solvent recommends an Occupational Exposure Limit for solvent
naphtha (petroleum), heavy aromatic: TWA: 100 mg/m?(15 ppm).
For the small amount of naphthalene present in the solvent the NOHSC Occupational Exposure
Limits are: TWA: 10 ppm (52 mg/m?, STEL: 15 ppm (79 mg/m?.
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.
Exposure standard ?Short term exposure limit (STEL) means a 15 minute TWA exposure which
should not be exceeded at any time during the working day.
Biological limit None allocated
values
Engineering controls Control process conditions to avoid contact. Use in a well-ventilated area only.
Personal Protective Eyes: Goggles or face-shield
Equipment Clothing: Cotton overalls buttoned to the neck and wrist (or equivalent clothing).
Gloves: Elbow-length PVC or nitrile gloves.
Respiratory: If airborne concentrations are likely to exceed the exposure
standards above or if inhalation of vapour is likely, an AS/NZS 1715/1716
approved respirator should be worn.

11. TOXICOLOGICAL INFORMATION
POTENTIAL HEALTH EFFECTS
Inhalation Product is expected to have low toxicity by the inhalation route. High vapour concentrations
may be irritating to the respiratory tract, may cause headaches, drowsiness and dizziness,
could be anaesthetic and may have other central nervous system effects.
Skin contact Will irritate the skin. May cause sensitisation by skin contact. The product is expected to have
low acute dermal toxicity. Repeated exposure may cause skin dryness or cracking.
Eye contact Will damage the eyes.
Ingestion May be harmful if swallowed. Small amounts of liquid aspirated into the respiratory system
during ingestion or from vomiting may cause bronchopneumonia or pulmonary oedema.
ANIMAL TOXICITY DATA ?PRODUCT
Acute:
Oral toxicity LD50 rat: 5000 mg/kg
Dermal toxicity LD50 rat: > 2000 mg/kg
Inhalation toxicity LC50 rat: > 1.33 mg/L (4h) - Mesosulfuron-methyl
Highest attainable concentration
Skin irritation Irritating to skin - rabbit
Eye irritation Severe eye irritation - rabbit
Sensitisation Non-sensitising
Chronic:
Mesosulfuron-methyl and mefenpyr-diethyl showed no mutagenicity, reproductive toxicity or carcinogenicity in animal
studies. Prolonged or repeated skin contact with the solvent in this product may result in irritation and dermatitis. This
product contains naphthalene. The International Agency for Research on Cancer evaluated naphthalene and concluded
that there was sufficient evidence for carcinogenicity in experimental animals, but inadequate evidence for cancer in
exposed humans. Accordingly, IARC classified naphthalene as a possible human carcinogen (Group 2B).

Environmental fate, Mesosulfuron-methyl is readily to slightly degradable in water. It is fairly degradable in soil
persistence, with a low potential for accumulation or persistence in the environment. Mesosulfuron-methyl
degradability and and its metabolites do not have significant leaching potential in soil. DT50 in field studies: 44 to
mobility 76 days (mesosulfuron-methyl).
13. DISPOSAL CONSIDERATIONS
Triple or preferably pressure rinse containers before disposal. Add rinsings to spray tank. Do not dispose of undiluted
chemicals on site. If recycling, replace cap and return clean containers to recycler or designated collection point. If not
recycling, break, crush, or puncture and bury empty containers in a local authority landfill. If no landfill is available, bury
the containers below 500 mm in a disposal pit specifically marked and set up for this purpose clear of waterways, desirable
vegetation and tree roots. Empty containers and product should not be burnt. If unwanted product cannot be used,
dispose of it through a reputable disposal contractor.
