Eyes DO NOT rub eyes. Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Then get immediate medical attention. Ingestion Rinse mouth. If swallowed, get medical attention. Most Important Symptoms/Effects Acute Causes respiratory tract irritation, skin irritation, eye irritation, allergic reactions. WOOD DUST: May cause nasal dryness, irritation and mucostasis. Coughing, wheezing, sneezing, sinusitis and prolonged colds have also been reported. Depending on wood species may cause respiratory sensitization and/or irritation. Symptoms can include irritation, redness, scratching of the cornea, and tearing. May cause eczema-like skin disorders (dermatitis). Airborne treated or untreated wood dust may cause nose, throat, or lung irritation and other respiratory effects. Delayed May cause cancer by inhalation. May damage fertility or the unborn child. Indication of any immediate medical attention and special treatment needed Treat symptomatically. May aggravate respiratory ailments such as asthma and bronchitis. Section 5 - FIRE FIGHTING MEASURES Extinguishing Media Suitable Extinguishing Media Carbon dioxide, regular foam, dry chemical, water spray, or water fog. Unsuitable Extinguishing Media Do not scatter spilled material with high-pressure water streams. Special Hazards Arising from the Chemical Combustible dust. May form combustible dust concentrations in air. Avoid generating dust; fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard. Depending on moisture content, and more importantly, particle diameter and airborne concentration, wood dust in a contained area may explode in the presence of an ignition source. Wood dust may similarly deflagrate (combustion without detonation like an explosion) if ignited in an open or loosely contained area. An airborne concentration of 40 grams (40,000 mg) of dust per cubic meter of air is often used as the LEL for wood dusts. Reference NFPA Standards- 654 and 664 for guidance. Hazardous Combustion Products Oxides of carbon, oxides of nitrogen. Fire Fighting Measures Wet down with water to reduce likelihood of ignition or dispersion. Move material from fire area if it can be done without risk. Avoid inhalation of material or combustion by-products. Stay upwind and keep out of low areas. Keep unnecessary people away, isolate hazard area and deny entry. The presence of the fire-retardant chemical in treated wood may reduce the flammability hazard to some extent. Special Protective Equipment and Precautions for Firefighters Wear full protective firefighting gear including self-contained breathing apparatus (SCBA) for protection against possible exposure. Section 6 - ACCIDENTAL RELEASE MEASURES Personal Precautions, Protective Equipment and Emergency Procedures Eliminate all sources of ignition. Wear personal protective clothing and equipment, see Section 8. Avoid dust generation and accumulation. Avoid dust formation. Avoid breathing dust. Methods and Materials for Containment and Cleaning Up Collect material in appropriate container for disposal. Avoid dispersal of dust in the air (i.e., clearing dust surfaces with compressed air). Collect using a vacuum cleaner with a HEPA filter or wet and scoop up dry spills. Dust deposits should not be allowed to accumulate on surfaces, as these may form an explosive mixture if they are released into the atmosphere in sufficient concentration. Avoid sweeping spilled dry material. If sweeping of a contaminated area is necessary, use a dust suppressant agent. Eliminate all sources of ignition. Keep unnecessary people away, isolate hazard area and deny entry. Environmental Precautions Avoid release to the environment. Section 7 - HANDLING AND STORAGE Precautions for Safe Handling Avoid breathing dust. Avoid contact with skin and eyes. Wash thoroughly after handling. Wear respiratory protection. Contaminated work clothing must not be allowed out of the workplace. Use only outdoors or in a well- ventilated area. Wear protective gloves/clothing and eye/face protection. Obtain special instructions before use. Do not handle until all safety precautions have been read and understood. Minimize dust generation and accumulation. Routine housekeeping should be instituted to ensure that dusts do not accumulate on surfaces. Avoid significant deposits of material, especially on horizontal surfaces, which may become airborne and form combustible dust clouds and may contribute to secondary explosions. Dry wood dust material is defined as having a water content less than 25% by weight. Sweep or vacuum but avoid generating dust. Avoid working with freshly treated wood. Do not burn treated wood. Gently moisten dust before it is collected. Clothing should be removed and replaced if it becomes wet due to contact with freshly treated wood. Conditions for Safe Storage, Including any Incompatibilities Store in a well-ventilated place. Store and handle in accordance with all current regulations and standards. Avoid heat, flames, sparks and other sources of ignition. Store containers in a cool, dry, well-ventilated place. Store away from incompatible materials (see Section 10, Stability and Reactivity). Incompatible Materials strong oxidizing agents, reducing agents. Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION Component Exposure Limits Wood/Wood dust N/A ACGIH: 1 mg/m3 TWA Inhalable fraction NIOSH: 1 mg/m3 TWA dust OSHA (US): 5 mg/m3 PEL (respirable dust); 15 mg/m3 PEL (total fraction) Boric acid (H3BO3) 10043-35-3 ACGIH: 2 mg/m3 TWA inhalable particulate matter 6 mg/m3 STEL inhalable particulate matter ACGIH - Threshold Limit Values - Biological Exposure Indices (BEI) There are no biological limit values for any of this product's components. Engineering Controls Ventilation equipment should be explosion-resistant if explosive concentrations of material are present. Provide local exhaust or process enclosure ventilation system. Ensure that dust-handling systems (such as exhaust ducts, dust collectors, vessels, and processing equipment) are designed in a manner to prevent the escape of dust into the work area (i.e., there is no leakage from the equipment). Ensure compliance with applicable exposure limits. Individual Protection Measures, such as Personal Protective Equipment Eye/face protection Wear safety glasses with side shields or chemical safety goggles. Skin Protection Wear appropriate work clothing. Wear fire/flame resistant/retardant clothing. Refer to NFPA 2112, Standard on Flame‐Resistant Garments for Protection of Industrial Personnel Against Flash Fire and NFPA 2113, Standard on the Selection, Use, Care and Maintenance of Flame‐Resistant Garments for Protection of Industrial Personnel Against Short-duration Thermal Exposures from Fire (2015). Respiratory Protection If engineering controls do not maintain airborne concentrations to a negligible level, an approved respirator must be worn. A NIOSH approved air-purifying respirator with an appropriate cartridge or canister may be appropriate under certain circumstances where airborne concentrations are expected to exceed exposure limits. Glove Recommendations Wear general purpose work gloves: flame-resistant.
