Section 4 - FIRST AID MEASURES

SWALLOWED• Immediately give a glass of water.• First aid is not generally required. If in doubt, contact a PoisonsInformation Centre or a doctor.

EYEIf this product comes in contact with the eyes:• Immediately hold eyelids apart and flush the eye continuously with runningwater.• Ensure complete irrigation of the eye by keeping eyelids apart and away fromeye and moving the eyelids by occasionally lifting the upper and lower lids.• Continue flushing until advised to stop by the Poisons Information Centre or adoctor, or for at least 15 minutes.• Transport to hospital or doctor without delay.• Removal of contact lenses after an eye injury should only be undertaken byskilled personnel.

SKINIf skin contact occurs:• Immediately remove all contaminated clothing, including footwear• Flush skin and hair with running water (and soap if available).• Seek medical attention in event of irritation.

INHALED• If fumes or combustion products are inhaled remove from contaminated area.• Other measures are usually unnecessary.

NOTES TO PHYSICIANTreat symptomatically.

Section 5 - FIRE FIGHTING MEASURES

Section 5 - FIRE FIGHTING MEASURES ...

FIRE FIGHTING• Alert Fire Brigade and tell them location and nature of hazard.• Wear breathing apparatus plus protective gloves for fire only.• Prevent, by any means available, spillage from entering drains or watercourses.• Use fire fighting procedures suitable for surrounding area.• DO NOT approach containers suspected to be hot.• Cool fire exposed containers with water spray from a protected location.• If safe to do so, remove containers from path of fire.• Equipment should be thoroughly decontaminated after use.

FIRE/EXPLOSION HAZARD• Non combustible.• Not considered a significant fire risk, however containers may burn.Decomposition may produce toxic fumes ofcarbon dioxide (CO2)other pyrolysis products typical of burning organic materialMay emit corrosive fumes.

FIRE INCOMPATIBILITYAvoid contamination with oxidising agents i.e. nitrates, oxidising acids,chlorine bleaches, pool chlorine etc. as ignition may result

HAZCHEM

None

Personal Protective Equipment

PERSONAL PROTECTION EQUIPMENTGas tight chemical resistant suit.Limit exposure duration to 1 BA set - 30 mins.

Section 6 - ACCIDENTAL RELEASE MEASURES

EMERGENCY PROCEDURES

MINOR SPILLS• Clean up all spills immediately.• Avoid breathing vapours and contact with skin and eyes.• Control personal contact by using protective equipment.• Contain and absorb spill with sand, earth, inert material or vermiculite.• Wipe up.• Place in a suitable labelled container for waste disposal.

MAJOR SPILLSModerate hazard.• Clear area of personnel and move upwind.

Section 6 - ACCIDENTAL RELEASE MEASURES ...

• 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 watercourse.• Stop leak if safe to do so.• Contain spill with sand, earth or vermiculite.• Collect recoverable product into labelled containers for recycling.• Neutralise/decontaminate residue.• Collect solid residues and seal in labelled drums for disposal.• Wash area and prevent runoff into drains.• After clean up operations, decontaminate and launder all protective clothingand equipment before storing and re-using.• If contamination of drains or waterways occurs, advise emergency services.

Personal Protective Equipment advice is contained in Section 8 of the MSDS.

Section 7 - HANDLING AND STORAGE

PROCEDURE FOR HANDLING

• Limit all unnecessary personal contact.• Wear protective clothing when risk of exposure occurs.• Use in a well-ventilated area.• When handling DO NOT eat, drink or smoke.• Always wash hands with soap and water after handling.• Avoid physical damage to containers.• Use good occupational work practice.• Observe manufacturer's storing and handling recommendations.DO NOT allow clothing wet with material to stay in contact with skin

SUITABLE CONTAINER• Polyethylene or polypropylene container.• Packing as recommended by manufacturer• Check all containers are clearly labelled and free from leaks.

STORAGE INCOMPATIBILITYAvoid reaction with oxidising agents

STORAGE REQUIREMENTSStore in a cool area and away from sunlight.• Store in original containers.• Keep containers securely sealed.• Store in a cool, dry, well-ventilated area.• Store away from incompatible materials and foodstuff containers.• Protect containers against physical damage and check regularly for leaks.• Observe manufacturer's storing and handling recommendations.

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION

EXPOSURE CONTROLS

Not available. Refer to individual constituents.

PERSONAL PROTECTION

EYE• Safety glasses with side shields• Chemical goggles.• Contact lenses pose a special hazard; soft lenses may absorb irritants and alllenses concentrate them.

HANDS/FEETWear chemical protective gloves, eg. PVC.Wear safety footwear or safety gumboots, eg. RubberNOTE: The material may produce skin sensitisation in predisposed individuals.Care must be taken, when removing gloves and other protective equipment, toavoid all possible skin contact.

OTHERNo special equipment needed when handling small quantities.OTHERWISE:• Overalls.• Barrier cream.• Eyewash unit.Use dust mask while grinding.

The local concentration of material, quantity and conditions of use determinethe type of personal protective equipment required. For further informationconsult site specific CHEMWATCH data (if available), or your OccupationalHealth and Safety Advisor.

ENGINEERING CONTROLS

General exhaust is adequate under normal operating conditions. If risk ofoverexposure exists, wear SAA approved respirator. Correct fit is essential toobtain adequate protection. Provide adequate ventilation in warehouse or closedstorage areas.

Section 11 - TOXICOLOGICAL INFORMATION

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED(No Oral LD50, any animal species) The material has NOT been classified by ECDirectives or other classification systems as "harmful by ingestion". This isbecause of the lack of corroborating animal or human evidence. The material maystill be damaging to the health of the individual, following ingestion,especially where pre-existing organ (eg. liver, kidney) damage is evident.Present definitions of harmful or toxic substances are generally based on dosesproducing mortality rather than those producing morbidity (disease, ill-health).Gastrointestinal tract discomfort may produce nausea and vomiting. In anoccupational setting however, ingestion of insignificant quantities is notthought to be cause for concern.

EYEAlthough the liquid is not thought to be an irritant (as classified by ECDirectives), direct contact with the eye may produce transient discomfortcharacterised by tearing or conjunctival redness (as with windburn).

Section 11 - TOXICOLOGICAL INFORMATION ...

SKINThe material is not thought to produce adverse health effects or skin irritationfollowing contact (as classified by EC Directives using animal models).Nevertheless, good hygiene practice requires that exposure be kept to a minimumand that suitable gloves be used in an occupational setting.

INHALEDThe material is not thought to produce adverse health effects or irritation ofthe respiratory tract (as classified by EC Directives using animal models).Nevertheless, good hygiene practice requires that exposure be kept to a minimumand that suitable control measures be used in an occupational setting.

CHRONIC HEALTH EFFECTSThere is limited evidence that, skin contact with this product is more likely to cause asensitisation reaction in some persons compared to the general population.
