Special hazards arising from the substance or mixture None inherent in this product. Hazardous Decomposition or By-Products Substance Condition Carbon monoxide During Combustion Carbon dioxide During Combustion Irritant Vapors or Gases During Combustion 5.3. Special protective actions for fire-fighters No special protective actions for fire-fighters are anticipated. 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 vapors, 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. For information regarding physical and health hazards, refer to sections 2 and 11 of the SDS. 6.2. Environmental precautions Avoid release to the environment. 6.3. Methods and material for containment and cleaning up Collect as much of the spilled material as possible. Place in a closed container approved for transportation by appropriate authorities. Clean up residue. Seal the container. Dispose of collected material as soon as possible in accordance with applicable local/regional/national/international regulations. __________________________________________________________________________________________ Page 3 of 11 RelyX™ Unicem™ 2 Automix Catalyst 02/12/26 SECTION 7: Handling and storage 7.1.
