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.
Symptoms Local: Severe eye irritation, skin and respiratory tract irritation. Repeated exposure may cause
skin dryness or cracking.
Systemic: Headaches, dizziness, could be anesthetic and may have other central nervous
system effects. May cause lung damage if swallowed.
There have been no reports of adverse effects on human health in manufacturing plant workers
exposed to mesosulfuron-methyl or from experimental agricultural use of Atlantis.
Medical attention This product is a severe eye irritant. Consultation with an ophthalmologist is advised.
Treatment should be symptomatic and supportive after decontamination. If a large amount
(more than one mouthful) was ingested, the following measures should be considered: -
Monitor kidney function, liver function and red blood cell count.
Carry out gastric lavage and charcoal administration. Cathartic administration of sodium
sulphate is appropriate for poisoning with mefenpyr-diethyl.
As this product contains a hydrocarbon solvent, 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.
Elimination by forced alkaline diuresis is appropriate for poisoning with mesosulfuron.
Anticonvulsant therapy is not indicated. There is no specific antidote and no contraindications.
5. FIRE FIGHTING MEASURES
Extinguishing media Water spray, foam, carbon dioxide, dry agent
Hazards from Hydrogen chloride, nitrogen oxides, oxides of carbon and sulphur and other toxic compounds
combustion products may be released in a fire.
Precautions for fire The product is a Class C1 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. 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.

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鈥檚 use, wash gloves, face-shield or goggles and contaminated clothing.
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 all ignition sources and protect from extreme heat
and cold.
Flammability Combustible liquid, Class C1 - flashpoint between 61掳 C and 150潞 C.
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鲁 (15 ppm).
For the small amount of naphthalene present in the solvent the NOHSC Occupational Exposure
Limits are:
TWA: 10 ppm (52 mg/m鲁), STEL: 15 ppm (79 mg/m鲁). Skin notation.
Definitions:
Exposure standard 鈥? 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 鈥? Short term exposure limit (STEL) means a 15 minute TWA exposure which
should not be exceeded at any time during the working day.
Skin notation 鈥? Absorption through the skin may be a significant source of exposure.
Engineering controls Control process conditions to avoid contact. Use local exhaust ventilation during manufacture.
Use in a well-ventilated area only.
鈥?
Personal Protective Face-shield or goggles
Equipment 鈥? Cotton overalls buttoned to the neck and wrist (or equivalent clothing) and a washable hat
鈥? Elbow-length PVC or nitrile gloves
鈥? If airborne concentrations are likely to exceed the exposure standards above, an AS/NZS
1715/1716 approved respirator should be worn.

11. TOXICOLOGICAL INFORMATION
POTENTIAL HEALTH EFFECTS
Inhalation The active ingredient has low inhalation toxicity. No data are available for the product.
Inhalation of solvent vapour may be irritating to respiratory tract, may cause headaches and
dizziness, could be anaesthetic, and may have other central nervous system effects.
Skin contact Will irritate the skin. The product had low acute dermal toxicity in the rat, and was not
sensitising in the test with guinea pigs. 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.

Chronic:
Mesosulfuron-methyl and mefenpyr-diethyl showed no mutagenicity, reproductive toxicity or carcinogenicity in animal
studies. Prolonged or repeated skin contact with the hydrocarbon 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).
12. ECOLOGICAL INFORMATION

and Daphnia. It has low toxicity to bees, birds, and earthworms.
DO NOT contaminate streams, rivers or waterways with the chemical or used containers.
Ecotoxicity Atlantis:
LC50: 3.2 mg/L (96 h) rainbow trout
EC50: 3.4 mg/L (48 h) Daphnia magna
Algal toxicity:
EC50 (72 h) for Pseudokirchneriella subcapitata 2.0 mg/L
Mesosulfuron-methyl:
LC50: > 100 mg/L (96 h) rainbow trout
EC50: > 100 mg/L (48 h) Daphnia magna
Algal toxicity:
EC50 (72 h) for Pseudokirchneriella subcapitata 0.18 mg/L
Bird toxicity:
Acute oral LD50: > 2000 mg/kg bobwhite quail and mallard duck
Environmental fate, Mesosulfuron-methyl is readily to slightly degradable in water. It is fairly degradable in soil
persistence and with a low potential for accumulation or persistence in the environment. Mesosulfuron-methyl
degradability and its metabolites do not have significant leaching potential in soil.
DT50 in field studies: 44 to 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. Dispose of waste product through a
reputable waste contractor.
