SECTION 2: Hazards identification

NOT CLASSIFIED AS HAZARDOUS ACCORDING TO ASCC CRITERIA NOT CLASSIFIED AS A DANGEROUS GOOD BY THE CRITERIA OF THE ADG CODE UN No. None Allocated DG Class None Allocated Subsidiary Risk(s) None Allocated Packing Group None Allocated Hazchem Code None Allocated EPGN None Allocated OVERVIEW Dust Hazard: Occupational exposure to wood dust from any timber product has been classified as hazardous according to the criteria of the National Occupational Health and Safety Commission (NOHSC). Inhalation of excessive amounts of dust may cause temporary upper respiratory irritation and/or congestion; and irritation of the eyes and skin. Repeated inhalation of wood dust increases the risk of nasal cancer and may increase the risk of lung fibrosis. Formaldehyde gas may be released under some conditions particularly when the boards are heated and laminated, or cut by laser cutting machines. However, in well ventilated storage areas and workplaces, the concentration of formaldehyde is unlikely to exceed the World Health Organisation Standard of 0.1 mg/m3 for the general environment (30 minute average concentration) and it will be well below the NOHSC Occupational Exposure Standard of 1.2 mg/m3 TWA. Wood dust may be produced from machining the product, and formaldehyde gas may be produced from heating processes. Explosion Hazard: Wood dust may ignite at temperatures greater than 204oC/400oF, and high concentrations-in-air (>60g/m3) may spontaneously explode.

Potential health effects

Acute (short term) Health Effects: Swallowed: Unlikely under normal conditions. Swallowing the dust may cause abdominal discomfort. Eye: Wood dust and the resin may be irritating to the eyes resulting in redness and watering. Skin: Skin contact with wood dust and the resin may result in skin itching and redness, and dermatitis in some people. Inhaled: Inhalation of wood dust and resin may be irritating to the nose, throat and lungs. Repeated exposure over many years to uncontrolled wood dust increases the risk of nasal cavity cancer. Inhalation of wood dust may also increase the risk of lung fibrosis (scarring). There are also increased risks of respiratory and skin sensitisation from wood dust and resin resulting in asthma and dermatitis respectively. Wood dust has been evaluated by the International Agency for Research on Cancer (IARC) as group 1, carcinogenic to humans. Formaldehyde has been evaluated by the International Agency for Research on Cancer (IARC) as group 1, carcinogenic to humans, and the current European Union (EU) classification under the Dangerous Substances Directive as category 3 (C3) carcinogen leading to a risk phrase R 40 (Limited evidence of a carcinogenic effect).

Measured as inspirable particulates. sen - sensitising to skin and respiratory tract (ii) formaldehyde: TWA 1.0 ppm (1.2 mg/m3); STEL 2.0 ppm (2.5 mg/m3). sen - sensitiser; Cat 3 (possible human) carcinogen. < Company > recommendation: Keep exposures as low as practicable with the aim of keeping dust exposures below 1.0 mg/m3 measured as inspirable dust. Note: The ingredients are bonded together under heat and pressure. The process cures the resin but small amounts of formaldehyde from the resin may be released from the finished product. The finished product contains less than 0.01% free formaldehyde by weight. The proportion of paint on coated products is less than 1 % of the board mass. Potential exposures to dust will occur only when power tools or wood working machinery is used on the product such as planing, sawing, drilling or sanding, or in poorly maintained workshops.
