LOSP Treated Timber
STATEMENT OF HAZARDOUS NATURE
Not hazardous according to criteria of Worksafe Australia.
COMPANY DETAILS
IDENTIFICATION
LOSP TREATED TIMBER
LOSP treatment is used to protect timber from attack by termites, insectsand fungal decay. The treated timber is used for exterior building andstructural applications in above ground situations. LOSP treatment is notsuitable for timber that will be used in ground contact hazard situations.
Physical Description /Properties
Appearance & Odour
Sawn timber appearance with a slight pale yellow colouration. May have anoily organic odour fresh after treatment. May have an orange to gold coloureddye impregnated during treatment Typically 450 - 650 kg/m3 depending on timber species and grade.
Not applicable (for solvent - LEL 0.8%, UEL 6.0%) Ingredients
Chemical Name
CAS Number
Proportion % w/w
Commercial timbers such as radiata pine, slash pine, hoop pine etc. treated by vacuum/pressureimpregnation method.
*Permethrin 25:75 #Residual solvent (aliphatic hydrocarbons) * Actual levels from piece to piece may vary depending on the application intended and differences in the timber itself.
# The level of residual solvent in the timber will vary considerably depending on the length of time after the treatment and the
drying conditions. Levels of up to 10% by weight may be expected immediately after treatment however this falls to negligible
levels within a few days at ambient conditions once the solvent is allowed to dry.

HEALTH HAZARD INFORMATION
Health Effects
Acute
Swallowed
Wood fibres may cause abdominal pain, nausea or diarrhoea. Unlikely to be asignificant route of over-exposure.
May be an irritant. May cause conjunctivitis and dryness.
May cause skin irritation. Contact with skin may result in allergic dermatitis.
Wood dust may cause breathing difficulties. May irritate the mucousmembranes of the upper respiratory tract. Inhalation of solvent vapours maycause headache, dizziness, nausea and confusion.
Wood dust may cause skin irritation and breathing difficulties. May aggravateasthma, eye infections or affect wearing of contact lenses. Exposure to airborne wood dust over long periods of time has been associated with thedevelopment of nasal cancer.
Once the treatment is dry, wood working and wood dust are not expected to beroutes of overexposure to the active constituent or the solvent. In general,studies of wood workers using treated timbers have not shown increased risksof cancer or other health problems over wood workers using untreated timbers.
First Aid
Swallowed
Do not induce vomiting. Seek medical attention.
Hold eyes open and flush with plenty of water. If irritation or pain persists,seek medical attention.
Wash affected area with soap and water.
Remove affected person to fresh air.
Eye wash, hand wash, bandages and antiseptic.
Advice to Doctor
Treat symptomatically. Regular medical surveillance for skin and systemiceffects is necessary for persons handling wet treated timber or who work in thetreatment plant. Note: Health effects of exposure to untreated timber(dust/shavings) may be the same for dry treated timber.
PRECAUTIONS FOR USE
Exposure limit standards for some of the constituents of this preparation are asfollows:Constituent: Note: An exposure standard for permethrin has not been set. However, anexposure standard (TWA) of 5mg/m3 has been allocated for pyrethrum (orpyrethrins).
Mechanical (general) ventilation is recommended if working in enclosedspaces or where wood dust is generated.

PRECAUTIONS FOR USE continued
For normal work on dry treated wood a dust mask and goggles should be wornas protection from wood dust when machining or sawing. Soft leather orcotton gloves should be worn to protect against splinters and cuts. Use goodhygiene practices such as washing hands after handling timber and beforeeating, drinking and smoking. When working with timber wet immediatelyafter treatment (before fixation), wear PVC or rubber gloves, an imperviouswork apron and work shoes. Wash hands and arms before eating, drinking,smoking or using the toilet and at the end of the day. Launder work clothesseparately from the household laundry. Some individuals may experiencesome sensitisation or skin irritation from contact with the treated wood. Thetreatment solution itself may be irritating to the eyes and skin.
SAFE HANDLING INFORMATION
Non-hazardous once timber is dried and chemical elements "fixed". treatedtimber should be held on the treatment plant premises for a sufficient period(at least two days) to ensure surface dryness and fixation of the preservative.
Storage areas should be well ventilated while the timber is drying aftertreatment. Tests have shown that LOSP treated timber is not significantlymore flammable than untreated timber after the solvent has evaporated. Avoidhandling or sawing freshly treated wet timber.
No special clean up procedure required. LOSP treated wood waste is not ahazardous material. Dispose of treated wood waste in a normal landfill tip inaccordance with local and state regulations. Do not use as cooking, BBQ orhome heating fuel. Burning the wood waste may be done in industrialincinerators, open fires and other situations away from occupied areas,foodstuffs or animals. Avoid breathing the combustion fumes and bury anyash in approved landfill in accordance with local and state regulations. Ashmay contain residues of tin oxides.
LOSP treatment does not contribute to increased flammability or energyrelease from the wood once dry after treatment. During combustion treatedwood may emit toxic vapours (carbon dioxide, carbon monoxide, tin oxides,smoke). Wood dusts may form explosive mixtures with air. Full protectiveclothing and self-contained breathing apparatus should be worn for firefighting. Extinguish fire with water, fog, foam, carbon dioxide or drychemical. Disposed of ash and burnt waste in approved landfill in accordancewith local and state regulations.
OTHER INFORMATION
The preservative is toxic to fish and wildlife but treated timber is not considered a hazard as the preservative becomes fixed onto the timber.
However timber treated with the preservative should not be used in situationswhere leaching is enhanced.
