Section 4 - FIRST AID MEASURES

SWALLOWED• If swallowed do NOT induce vomiting.

• If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration.• Observe the patient carefully.• Never give liquid to a person showing signs of being sleepy or with reduced awareness; i.e. becoming unconscious.

EYE■ If this product comes in contact with the eyes:• Wash out immediately with fresh running water.• Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lowerlids.

• Seek medical attention without delay; if pain persists or recurs seek medical attention.• Removal of contact lenses after an eye injury should only be undertaken by skilled personnel.

SKIN■ If 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 PHYSICIAN■ Treat symptomatically.Both dimercaptol and calcium disodium edetate are said to be effective in acute experimental tungsten poisonings.

Section 5 - FIRE FIGHTING MEASURES

EXTINGUISHING MEDIA• 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 for fire only.• Prevent, by any means available, spillage from entering drains or water courses.• Use fire fighting procedures suitable for surrounding area.

FIRE/EXPLOSION HAZARD• Non combustible.• Not considered a significant fire risk, however containers may burn.May emit poisonous fumes.

FIRE INCOMPATIBILITY■ None known.

HAZCHEM•3Z

Personal Protective EquipmentGloves, boots (chemical resistant).Breathing apparatus.

Section 6 - ACCIDENTAL RELEASE MEASURES

MINOR SPILLS■ Environmental hazard - contain spillage.• Clean up all spills immediately.• Avoid contact with skin and eyes.

• Wear impervious gloves and safety goggles.• Trowel up/scrape up.

MAJOR SPILLS• Clear area of personnel and move upwind.• 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 course.Environmental hazard - contain spillage.

CD 2010/2 of 6Section 6 - ACCIDENTAL RELEASE MEASURES

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

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.

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

STORAGE INCOMPATIBILITY• WARNING: Avoid or control reaction with peroxides. All transition metal peroxides should be considered as potentially explosive. For exampletransition metal complexes of alkyl hydroperoxides may decompose explosively.

• The pi-complexes formed between chromium(0), vanadium(0) and other transition metals (haloarene-metal complexes) and mono-or poly-fluorobenzeneshow extreme sensitivity to heat and are explosive.

• Avoid reaction with borohydrides or cyanoborohydrides.• 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.

PERSONAL PROTECTION

EYE• Safety glasses with side shields.• Chemical goggles.• Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants. A written policy document, describing the

wearing of lens or restrictions on use, should be created for each workplace or task. This should include a review of lens absorption andadsorption for the class of chemicals in use and an account of injury experience. Medical and first-aid personnel should be trained in theirremoval and suitable equipment should be readily available. In the event of chemical exposure, begin eye irrigation immediately and remove contactlens as soon as practicable. Lens should be removed at the first signs of eye redness or irritation - lens should be removed in a clean environmentonly after workers have washed hands thoroughly. [CDC NIOSH Current Intelligence Bulletin 59].

HANDS/FEET• Wear chemical protective gloves, eg. PVC.• Wear safety footwear or safety gumboots, eg. Rubber.

OTHER• Overalls.• P.V.C. apron.

• Barrier cream.• Skin cleansing cream.

ENGINEERING CONTROLS■ General exhaust is adequate under normal operating conditions. Local exhaust ventilation may be required in specific circumstances.
