Hazards Identification
3.
Health hazards: Irritating to eyes and skin.
Environmental hazard in case of accident (spillage or leakage): Toxic to aquatic
organisms; may cause long term adverse effects in the aquatic environment.
First Aid Measures
4.
General: Have the product container, label or Materials Safety Data Sheet with you
when calling the Poisons Information Service, AgChemAccess, a physician or when
going for medical treatment. Move out of contaminated area and place victim in the
recovery position if necessary. Remove contaminated clothing and dispose of safely.
Skin Contact: Wash affected area immediately with plenty of water. Remove
contaminated clothing and wash thoroughly before re-use. If irritation persists, call a
physician.
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, including
under eyelids. Remove contact lenses if worn. Immediate medical attention is
required.
Inhalation: Remove patient to fresh air and seek medical advice. Keep the patient
warm and at rest. Administer artificial respiration if the patients' breathing is irregular or
has stopped. Contact a physician or the Poison Control Centre immediately.
Ingestion: If swallowed, rinse mouth with clean water and dispose of residues safely.
Make the patient drink activated charcoal if available in a large amount of water.
Contact a physician immediately and show this MSDS or the label.
Guide to Doctors: Treat symptoms as they occur. There is no specific antidote for
this product.
Fire-fighting measures:
5.
Extinguishing Media for small fires: Use alcohol-resistant foam, dry chemical (e.g.
sand), water spray or carbon dioxide.
Extinguishing Media for larger fires: Use alcohol-resistant foam or a water spray.
Extinguishing Media which should not be used for safety reasons: DO NOT USE
a solid water stream as this may scatter and spread the fire.
Specific hazards during fire-fighting: During a fire dense black smoke will be
produced as the product contains combustible organic components. This will contain
the products of combustion which may be toxic (see section 10 below). Flashback may
occur along a vapour trail. Evacuate downwind.
Special protective equipment for fire-fighters: Wear full protective clothing and
self-contained breathing apparatus. DO NOT breathe fumes.
Further Information: Contain fire-fighting water with sand or some such bunding
material to prevent entry to drains or water courses. Avoid breathing smoke. Cool
closed containers exposed to the fire with a water spray.
Accidental release measures:
6.
Personal precautionary measures: Wear the personal protective equipment outlined
in section 8 below. Remove contaminated clothing immediately. Wash skin area with
soap and water. Wash clothing before re-use.
Environmental protection measures: Keep the area isolated and do not allow
contamination to enter drains or waterways. Prevent further leakage if safe to do so.
Spillage or uncontrolled discharges into watercourses must be alerted to the National
Rivers Authority or Environmental Agency (Tel: 0800 807060).
Procedures for cleaning/absorption: Soak up with sand, earth or other non-
combustible absorbent material using mechanical handling equipment and place in
containers for disposal according to local/national regulations (see section 13). Clean
contaminated floors and objects thoroughly and dispose of cleaning equipment safely.
For large spillages, barricade the area and consult the manufacturer.
Handling and storage:
7.
Handling: Use the personal protective equipment detailed in section 8. Avoid contact
with eyes or skin. Ensure adequate ventilation and avoid sources of ignition and direct
sunlight. When using, do not eat, drink or smoke and wash hands and exposed skin
after work.
Storage: Store in a cool dry and well-ventilated place in the original containers away
from any source of ignition and protect from excessive heat or cold. Keep in an area
accessible to authorised personnel only. Keep out of reach of children and store away
from food, drink and animal feeding stuffs.
Additional information: The product is stable for at least two years when stored at
ambient temperatures in the unopened container. Ensure temperature does not
exceed 35癈.
Exposure controls/Personal protection:
8.
COMPONENTS WITH WORKPLACE CONTROL PARAMETERS
Components Exposure limits Values
Propaquizafop Not determined -
3
1-methyl-2-pyrrolidionone 19 ppm, 80 mg/m
3
Solvent naphtha (petroleum) 10 ppm, 52 mg/m
Engineering measures to reduce exposure: Good ventilation is essential to avoid
the build up of inflammable vapour. Engineering controls to avoid exposure are
preferable to personal protective equipment where practically feasible to use. Assess
the exposure and deploy additional measures if there is a chance that the relevant
exposure limit may be exceeded.
Personal protective equipment: Keep work clothes separate from other clothing.
Clothing that cannot be cleaned should be burned but soda solution can be used for
improved decontamination. When using, consult the label for appropriate protective
equipment. In all other situations, use the following personal protective equipment.
Eye protection: Follow local site procedure. Eye protection in the form of goggles or
face shield is recommended and when used, should comply with EN 166 certification.
Hand protection: Chemical-resistant gloves made of nitrile rubber are needed with a
breakthrough time appropriate to the length of exposure. Wash contamination from the
gloves immediately and dispose of safely if perforated or contaminated on the inside.
Wash hands before eating, drinking or smoking and before using the toilet.
Respiratory protection: No respiratory protection is normally required provided that
good ventilation is maintained.
Skin and body protection: Wear suitable protective clothing based on the potential
exposure risk over normal clothes to provide two barriers. When finished, wash with
soap and water after removing protective clothing. Take a shower if necessary.
Decontaminate clothing before re-use or use disposable clothing. Do not eat, drink or
smoke while working. Store away from food, drink or animal feeding stuffs.
