Physical hazards

None Skin Irritation: Causes mild skin irritation 3 Eye Irritation: Treated and untreated wood dust causes eye irritation 2B Respiratory Sensitization: Treated and untreated wood dust may cause allergy or asthma 1 symptoms or breathing difficulties if inhaled Skin Sensitization: May cause an allergic skin reaction due to prolonged and/or repeated 1 contact with treated or untreated wood dust. (Various species of untreated wood dust can elicit allergic type skin irritation in sensitized persons.) Carcinogenicity: May cause cancer due to long term inhalation of treated or untreated 1A wood dust above threshold limits Specific Target Organ 3 Toxicity (Single Exposure): May cause respiratory irritation

Prevention

• Do not cut or machine wood (generate wood dust) until all safety precautions have been read and understood. • Wear protective gloves, long sleeve shirt and pants when handling treated or untreated wood. • Wash face, hands and any exposed skin thoroughly after handling and before eating, drinking or using the restroom • Contaminated work clothing should not be allowed out of the workplace • Cut or machine treated/untreated wood only outdoors or in a well-ventilated area • Avoid breathing dust when cutting or machining wood • In case of inadequate ventilation and levels exceed the recommended exposure limits, wear a NIOSH approved P95 or better particulate filter respirator

Response

• IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. If eye irritation persists get medical attention. • IF INHALED: Remove person to fresh air and keep comfortable for breathing. If experiencing respiratory symptoms or feeling unwell, call physician or Poison Control Center • IF ON SKIN: Wash with plenty of water • If skin irritation or rash occurs, get medical attention. • IF exposed or concerned: Get medical attention. • Take off contaminated clothing and wash it before reuse.

Storage

• None

Precautionary statements

Disposal • Dispose of material in accordance with local, state and federal regulations Other • If mixed with air in the presence of an ignition source, sawing, sanding or machining wood may form explosible dust-air mixture if dispersed • Acute Target Organ Toxicity: Skin, Eyes, Respiratory tract • Chronic Target Organ Toxicity: Kidney, Liver, Lungs, Lymphatic System, Respiratory system • Diesel fuel may cause nose, throat, or lung irritation, drowsiness, dizziness, and loss of coordination. • Causes mild skin irritation (Prolonged and/or repeated contact with treated or untreated wood dust. Various species of untreated wood dust can elicit allergic type skin irritation in sensitized persons.) • Odor: Fuel oil type odor Physical State: solid Immediate (Acute) Health Effects Inhalation: Airborne treated or untreated wood dust may cause nose, throat or lung irritation. Avoid breathing dust when cutting or machining wood. Diesel fuel may cause nose, throat, or lung irritation, drowsiness, dizziness, and loss of coordination. Wear respiratory protection if needed. Eye Contact: Treated or untreated wood dust may cause eye irritation. Diesel fuel may cause eye irritation. Wear Protective eyewear. Skin Contact: Handling wood may result in skin exposure to splinters. Diesel fuel may cause skin irritation. Wear protective gloves and clothing. Ingestion: Not anticipated to occur. A single ingestion of a very large dose of treated wood dust may require immediate medical attention. Acute Target Organ Toxicity: Skin, Eyes, Respiratory tract

Potential chronic health

Carcinogenicity: Carcinogenicity Data: IARC has classified untreated hardwood and hardwood/softwood mix wood dust as a Group 1 human carcinogen. The wood dust classification is based primarily on IARC's evaluation of increased risk in the occurrence of adenocarcinomas of the nasal cavities and para-nasal sinuses associated with occupational exposures to untreated wood dust. NTP has classified all untreated wood dust as a carcinogen. Pentachlorophenol is possibly carcinogenic to humans (IARC Group 2B). 2.
