SECTION 4 - TOXICOLOGICAL PROPERTIES

NATURE OF HAZARD

INHALATION: The vapours have a low to moderate toxicity. In high concentrations the vapours are irritating and anaesthetic.

The irritating properties give warning as anaesthetic concentrations are approached. However, a similar type of solvent has

produced kidney damage in experimental animals. To date no chronic effects have been reported in man.



EYE CONTACT: Slightly irritating, but does not cause eye tissue damage.



SKIN CONTACT: Very low order of toxicity by skin absorption. However, frequent or prolonged contact may irritate the skin

and cause Defatting Dermatitis.

                                                        September 2006



INGESTION: Low order of toxicity. However, minute amounts aspirated into the lungs during swallowing or subsequent vomiting

may cause severe lung irritation.



CHRONIC: Laboratory animal studies have shown that prolonged and repeated inhalation exposure to light hydrocarbon vapours

in the same naphtha boiling range as this product can produce adverse kidney effects in male rats. However, these effects were

not observed in similar studies with female rats and male and female mice and in limited studies with other animal species.

Additionally, in a number of human studies, there was no clinical evidence of such effects at normal occupational levels. It is

therefore highly unlikely that the kidney effects observed in male rats have significant implications for humans exposed at or below

recommended vapour limits in the workplace.



OCCUPATIONAL EXPOSURE LIMIT: For vapour mixture: 100 ppm (575 mg/cu.m) total hydrocarbons recommended.



Notes to Physician: If aspirated into lungs, Hydrocarbon Solvents may cause Chemical Pneumonitis. Cardiac Arrythmias have been

reported with solvent exposure.



SECTION 5 - FIRST AID MEASURES

INHALATION: Rescuers should wear respiratory protection. Remove immediately from contaminated area. Apply artificial

respiration if breathing has stopped. Call a physician.



EYE CONTACT: Flush with large amounts of water for at least 15 minutes holding eyelids open, seek medical attention if irritation

persists.



SKIN CONTACT: Wash with large amounts of soap and water. Remove contaminated clothing including shoes.



INGESTION: Due to the possibility of aspiration into the lungs, do not induce vomiting, keep at rest and call a physician.



SECTION 6 - PREVENTIVE MEASURES

PERSONAL PROTECTION: Wear safety glasses with side shields, long sleeves, and chemical resistant gloves (PVC, Neoprene

Gloves). Where engineering, work practice or other means of exposure reduction are not adequate, approved respirators may be

necessary to prevent overexposure by inhalation.



ENGINEERING CONTROLS: Not necessary when product is applied outdoors or indoor application where small quantities are

used. For indoor applications involving the use of large quantities of product provide good passive ventilation or explosion proof

power ventilation.



HANDLING, STORAGE AND SHIPPING: Adequate ventilation should be provided to maintain the total hydrocarbon

concentration below the above mentioned occupational exposure limit. Avoid frequent or prolonged skin contact. Wear suitable eye

protection if the possibility of splashing exists. Keep container closed when not in use. Do not store product near fire exits, open

flames, sources of heat or sources of ignition. Post "NO SMOKING" signs in areas of application. Product is a static accumulator.

Take precautions as to adequate grounding etc., when transferring at temperatures near or above flash point. Containers of this

material may be hazardous when emptied. Emptied containers retain product residue (vapour, liquid etc.). Do not allow this

product to freeze, store above 0?    C.



SPILL CONTROL AND DISPOSAL:

LAND SPILL - Eliminate source of ignition. Keep public away. Prevent spill from entering sewers, watercourses or low areas.

Contain spilled liquid with sand or earth. Do not use combustible materials such as sawdust. Recover by using a suitable

absorbent. Ensure disposal is in compliance with government requirements and ensure conformity to local disposal regulations.



WATER SPILL: Remove from surface by skimming or with suitable adsorbents. If allowed by local authorities and environmental

agencies, sinking and/or suitable dispersants may be used in non-confined waters. Ensure disposal in compliance with government

requirements and ensure conformity to local disposal regulations. /...2

SECTION 7 - FIRE AND EXPLOSION DATA

Flash Point and Method: TCC: 42? (107?

                                 C      F).

Auto Ignition Temperature: 229? (444?

                                C      F)

Flammable Limits (Percent by Volume) (Lel) 1.1 (Uel) 6.0



GENERAL HAZARDS: Combustible Liquid, may release vapours that form flammable mixtures at or above the flash point. Toxic

gases will form upon combustion.



FIRE FIGHTING: Use water spray to cool fire exposed surfaces and to protect personnel. Use foam, dry chemical or water

spray to extinguish fire. Respiratory and eye protection required for fire fighting personnel. A self-contained breathing apparatus

(SCBA) should be used for all indoor fires and any significant outdoor fires. For small outdoor fires, which can easily be

extinguished with a portable fire extinguisher, use of an SCBA may not be required.



HAZARDOUS COMBUSTION PRODUCTS: Fumes, smoke and carbon monoxide.



SECTION 8 - REACTIVITY DATA

Stability: Stable

Materials/Conditions to Avoid: Strong oxidizing agents.

Hazardous Polymerization: Will not occur.
