Special hazards arising from the substance or mixture None inherent in this product. Hazardous Decomposition or By-Products Substance Condition Aldehydes. During combustion. Hydrocarbons. During combustion. Carbon monoxide During combustion. Carbon dioxide. During combustion. Hydrogen Chloride During combustion. Ketones. During combustion. Toxic vapour, gas, particulate. During combustion. 5.3. Advice for fire-fighters Wear full protective clothing, including helmet, self-contained, positive pressure or pressure demand breathing apparatus, bunker coat and pants, bands around arms, waist and legs, face mask, and protective covering for exposed areas of the head. SECTION 6: Accidental release measures 6.1. Personal precautions, protective equipment and emergency procedures Evacuate area. Ventilate the area with fresh air. For large spill, or spills in confined spaces, provide mechanical ventilation to disperse or exhaust vapours, in accordance with good industrial hygiene practice. Use personal protective equipment based on the results of an exposure assessment. Refer to Section 8 for PPE recommendations. If anticipated exposure resulting from an accidental release exceeds the protective capabilities of the PPE listed in Section 8, or are unknown, select PPE that offers an appropriate level of protection. Consider the physical and chemical hazards of the material when doing so. Examples of PPE ensembles for emergency response could include wearing bunker gear for a release of flammable material; wearing chemical protective clothing if the spilled material is a corrosive, a sensitizer, a significant dermal irritant, or can be absorbed through the skin; or donning a positive pressure supplied-air respirator for chemicals with inhalation hazards.
