SWALLOWED
Immediately give a glass of water.
First aid is not generally required. If in doubt, contact a Poisons Information Centre or a doct变善林温想校鸡却诉由乙or.
EYE
If this product comes in contact with eyes:
Wash out immediately with water.
If irritation continues, seek medical attention.
R灯绿系局互以德理emoval of con应切形斗tact lenses after an eye injury should only be undertaken by skilled personnel.
For THERMAL 围晚夫上慢阶销晶化burns:
Do NOT remove contact lens
La二却太高滑举视y victim down, on stretcher if available and pad BOTH eyes, make sure dressing does not press on the inj程石执井代和发出ured eye by 度做容异范继团口为placing thick pads under dressing, above and below the eye.
Seek urgent medical assistance, or transport to hospital.
SKIN
If skin or hair contact occurs:
Flush skin and hair with running water (and soap if available).
Seek medical attention in event of irritation.
In case of burns:
Immediately apply cold water to burn either by immersion or wrapping with saturated clean cloth.
DO NOT remove or cut away clothing over burnt areas. DO NOT pull away clothing which has adhered to the skin as this can cause further injury.
DO NOT break blister or remove solidified material.
Quickly cover wound with dressing or clean cloth to help prevent infection and to ease pain.
INHALED
If fumes, aerosols or combustion products are inhaled remove from contaminated area.
Other measures are usually unnecessary.
NOTES TO PHYSICIAN
Treat symptomatically.
Section 5 - FIRE FIGHTING MEASURES
EXTINGUISHING MEDIA
Do NOT direct a solid stream of water or foam into burning molten material; this may cause spattering and spread the fire.
Foam.
Dry chemical powder.
BCF (where regulations permit).
Carbon dioxide.
FIRE FIGHTING
Alert Fire Brigade and tell them location and nature of hazard.
Wear breathing apparatus plus protective gloves.
Prevent, by any means available, spillage from entering drains or water courses.
Use water delivered as a fine spray to control fire and cool adjacent area.
FIRE/EXPLOSION HAZARD
Combustion products include: carbon monoxide (CO), carbon dioxide (CO2), aldehydes, acrolein, nitrogen oxides (NOx), other pyrolysis products typical of burning organic material.
May emit clouds of acrid smoke.
NOTE: Burns with intense heat. Produces melting, flowing, burning liquid and dense acrid black smoke.
May emit corrosive fumes.
CARE: Contamination of heated / molten liquid with water may cause violent steam explosion, with scattering of hot contents.
FIRE INCOMPATIBILITY
Avoid contamination with oxidising agents i.e. nitrates, oxidising acids, chlorine bleaches, pool chlorine etc. as ignition may result
Section 6 - ACCIDENTAL RELEASE MEASURES
MINOR SPILLS
Clean up all spills immediately.
Avoid breathing dust and contact with skin and eyes.
Wear protective clothing, gloves, safety glasses and dust respirator.
Use dry clean up procedures and avoid generating dust.
MAJOR SPILLS
Moderate hazard.
CAUTION: Advise personnel in area.
Alert Emergency Services and tell them location and nature of hazard.
Control personal contact by wearing protective clothing.
Prevent, by any means available, spillage from entering drains or water courses.
Section 7 - HANDLING AND STORAGE
PROCEDURE FOR HANDLING
Avoid all personal contact, including inhalation.
Wear protective clothing when risk of exposure occurs.
Use in a well-ventilated area.
Prevent concentration in hollows and sumps.
Empty containers may contain residual dust which has the potential to accumulate following settling. Such dusts may explode in the presence of an appropriate ignition source.
Do NOT cut, drill, grind or weld such containers.
In addition ensure such activity is not performed near full, partially empty or empty containers without appropriate workplace safety authorisation or permit.
SUITABLE CONTAINER
Lined metal can, lined metal pail/ can.
Plastic pail.
Polyliner drum.
Packing as recommended by manufacturer.
STORAGE INCOMPATIBILITY
Avoid overheating in processing as this causes decomposition and degradation of polymer. This may start at temperatures above 90 deg.C, and becomes more rapid at higher temperatures with generation of highly irritating acetic acid vapour.
Avoid reaction with oxidising agents
STORAGE REQUIREMENTS
Store in original containers.
Keep containers securely sealed.
Store in a cool, dry, well-ventilated area.
Store away from incompatible materials and foodstuff containers.
Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
EXPOSURE CONTROLS
The following materials had no OELs on our records
• ethylene/ vinyl acetate copolymer: CAS:24937-78-8
PERSONAL PROTECTION
RESPIRATOR
# Type AB-P Filter of sufficient capacity. (AS/NZS 1716 & 1715, EN 143:2000 & 149:2001, ANSI Z88 or national equivalent)
EYE
Safety glasses with side shields.
Chemical goggles.
HANDS/FEET
Suitability and durability of glove type is dependent on usage. Important factors in the selection of gloves include:
frequency and duration of contact,
chemical resistance of glove material,
glove thickness and
dexterity
When handling hot materials wear heat resistant, elbow length gloves.
Rubber gloves are not recommended when handling hot objects, materials
Protective gloves eg. Leather gloves or gloves with Leather facing
Experience indicates that the following polymers are suitable as glove materials for protection against undissolved, dry solids, where abrasive particles are not present.
polychloroprene
nitrile rubber
butyl rubber
fluorocaoutchouc
OTHER
When handling hot or molten liquids, wear trousers or overalls outside of boots, to avoid spills entering boots.
Usually handled as molten liquid which requires worker thermal protection and increases hazard of vapour exposure.
CAUTION: Vapours may be irritating.
ENGINEERING CONTROLS
For molten materials:
Provide mechanical ventilation; in general such ventilation should be provided at compounding/ converting areas and at fabricating/ filling work stations where the material is heated. Local exhaust ventilation should be used over and in the vicinity of machinery involved in handling the molten material.
Keep dry!!
Processing temperatures may be well above boiling point of water, so wet or damp material may cause a serious steam explosion if used in unvented equipment.
Engineering controls are used to remove a hazard or place a barrier between the worker and the hazard. Well-designed engineering controls can be highly effective in protecting workers and will typically be independent of worker interactions to provide this high level of protection.
The basic types of engineering controls are:
Process controls which involve changing the way a job activity or process is done to reduce the risk.
Enclosure and/or isolation of emission source which keeps a selected hazard "physically" away from the worker and ventilation that strategically "adds" and "removes" air in the work environment.
