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 at all worried. 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 symptoms persist.
Eye contact Rinse eyes immediately with plenty of clean water and obtain urgent medical aid.
Ingestion Wash out mouth with water. Do NOT induce vomiting. Give water to drink. Keep patient
at rest and seek medical advice.
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 Symptoms
Local: Skin sensitisation, local irritation.
Systemic: headache, vomiting, lethargy, muscular twitching, liver and kidney function
disturbance, hypotension/hypertension. Ingestion of large amounts may cause central
nervous system depression, stupor, coma and respiratory failure.
Note for physicians
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.
Monitor respiratory, cardiac, kidney, liver and CNS functions. Observe blood pressure,
MCPA plasma level, urinary MCPA level and pH.
Gastric lavage and charcoal administration
Endotracheal intubation and artificial respiration, as necessary
Elimination by dialysis ?forced alkaline diuresis
Anticonvulsant therapy as necessary. If required, give diazepam 5-10 mg i.v. for adults
(pro rata for children) as necessary until fully sedated.
There is no specific antidote and no contraindications.
Recovery is expected to be spontaneous.
5. FIRE FIGHTING MEASURES
Extinguishing media Water spray, alcohol-resistant foam, carbon dioxide, dry agent

5. FIRE FIGHTING MEASURES ?continued
Precautions for fire Combustible liquid. N-methyl-2-pyrrolidone vapours are heavier than air. Fire fighters
fighters should wear full protective gear, including self-contained breathing apparatus (AS/NZS
1715/1716). Toxic decomposition products may be produced in a fire. If possible and
without risk, remove intact containers from exposure to fire. Otherwise, spray unopened
containers with water to keep cool. Keep unnecessary people away. Bund area to
prevent contamination of water sources. Dispose of fire control water and spillage safely
later.
Hazchem code Not applicable
6. ACCIDENTAL RELEASE MEASURES
Avoid contact with spilled material or contaminated surfaces. Extinguish or remove possible sources of ignition.
When dealing with spills do not eat, drink or smoke and 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, sealed drums for safe disposal. Deal with all spillages immediately. If contamination
of drains, streams, watercourses, etc. is unavoidable, warn the local water authority.
7. HANDLING AND STORAGE
Handling Avoid contact with eyes and skin, and do not inhale vapour. When opening the container
and preparing the spray, wear cotton overalls buttoned to the neck and wrist, washable
hat, elbow length PVC gloves and face shield or goggles. If product in eyes, wash it out
immediately with water. After use and before eating, drinking or smoking, wash hands,
arms and face thoroughly with soap and water. After each day's use, wash gloves, face
shield or goggles, and contaminated clothing. Keep away from all ignition sources.
Storage Store in the closed, original container in a cool, well-ventilated area. Do not store for
prolonged periods in direct sunlight.
Flammability Combustible liquid, Class C1 ?flashpoint between 61?C and 150?C.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Exposure standards The NOHSC exposure standard for N-methyl-2-pyrrolidone is:
TWA 25 ppm (103 mg/m3); STEL 75 ppm (309 mg/m3). Skin notation.
The manufacturer of the hydrocarbon solvent recommends the following occupational
exposure limit:
TWA: 50 ppm (323 mg/m3), as vapour.
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.
Skin notation ?Absorption through the skin may be a significant source of exposure.

Biological limit None allocated
values
Engineering controls Control process conditions to avoid contact. Use local exhaust ventilation during
manufacturing operations. Use in a well-ventilated area only.
Personal Protective Face-shield or goggles.
Equipment Cotton overalls buttoned to the neck and wrist and a washable hat.
Elbow-length PVC gloves
If inhalation exposure is likely to exceed the exposure levels above, an AS/NZS
1715/1716 approved respirator suitable for organic vapours should be worn.

13. DISPOSAL CONSIDERATIONS
When returnable container is empty or contents no longer required return it to the point of purchase. For non-
returnable containers, triple or (preferably) pressure rinse them 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 material via a reputable waste disposal contractor.
