Inhalation of solvent vapours may cause headache, dizziness, nausea and confusion. The wood dust may cause skin irritation and breathing difficulties. May aggravate asthma, eye infections or affect wearing of contact lenses. Exposure to any air borne wood dust over long periods of time has been associated with the development of nasal cancer. Long term excess exposure to or abuse of solvent vapour may result in adverse health effects such as impairment of brain function and organ damage. Once the treatment is dry, wood working and wood dust are not expected to be routes of overexposure to the active constituent or the solvent providing that appropriate personal protection and hygiene measures are taken. First Aid

H3 LOSP Azole Treated Wood Products
For normal work on dry treated wood a dust mask and goggles should be worn as protection from wood dust when machining or sawing. Soft leather or cotton gloves are recommended to be worn to protect against splinters and cuts. Use good hygiene practices such as washing hands after handling timber and before eating, drinking and smoking. When working with timber wet immediately after treatment (before drying), wear PVC or rubber gloves, an impervious work apron and work shoes. Where possible avoid working with freshly treated wood. Provide adequate ventilation to keep solvent vapours below exposure limits. Wash hands and arms before eating, drinking, smoking or using the toilet and at the end of the day. Launder work clothes separately from the household laundry. Use of a barrier cream to hands and arms may help alleviate skin dryness or sensitivity when working with the freshly treated wood. Some individuals may experience some sensitisation or skin irritation from contact with the freshly treated wood. The treatment solution itself may be irritating to the eyes and skin. Inhalation of solvent vapours irritate the respiratory tract and may cause headache, drowsiness and dizziness.
Storage and Transport Non-hazardous once timber is dried and chemical components are fixed.
Treated timber should be held on the treatment plant premises for a sufficient period (at least two to four days) to ensure surface dryness and fixation of the preservative. Storage areas should be well ventilated while the timber is drying after treatment. Tests have shown that LOSP treated timber is not significantly more flammable than untreated timber after the solvent has evaporated. Avoid handling or sawing freshly treated timber. No special clean up procedure required. LOSP treated wood waste is not a hazardous material. Dispose of treated wood waste in a normal landfill tip in accordance with local and state regulations. Do not use as cooking, BBQ or home heating fuel. Burning the wood waste may be done in industrial incinerators in accordance with local regulations. Avoid breathing the combustion fumes and bury any ash in approved landfill in accordance with local and state regulations. Fire/Explosion Hazard LOSP treatment does not significantly contribute to increased flammability or energy release from the wood once dry after treatment. During combustion treated wood may emit smoke and toxic fumes. Wood dusts may form explosive mixtures with air. Full protective clothing and self-contained breathing apparatus should be worn for fire fighting. Extinguish fire with water, fog, foam, carbon dioxide or dry chemical. Disposed of ash and burnt waste in approved landfill in accordance with local and state regulations. OTHER INFORMATION
