Cellu-Treat

SECTION 2: Hazards identification

AND PERSONAL OSHA PROTECTIVE EQUIPMENT INFORMATION EMERGENCY OVERVIEW: Cellu-Treat is a white, odorless, powdered substance that is not flammable, combustible, or explosive and has low acute oral and dermal toxicity. POTENTIAL ECOLOGICAL EFFECTS: Large amounts of Cellu-Treat can be harmful to plants and other species. Therefore, releases to the environment should he minimized.

Principle Routes of Exposure

Inhalation is the most significant route of exposure in occupational and other settings. Dermal exposure is not usually a concern because Cellu-Treat is poorly absorbed through intact skin. INHALATION: Occasional mild irritation effects to nose and throat may occur from inhalation of Cellu-Treat dust at levels greater than 10 mg/m3. EYE CONTACT: Cellu-Treat is non-irritating to eyes in normal use. SKIN CONTACT: Cellu-Treat does not cause irritation to intact skin. INGESTION: Products containing Cellu-Treat are not intended for ingestion. Cellu-Treat has a low acute toxicity. Small amounts (e.g., a teaspoonful) swallowed accidentally are not likely to cause effects; swallowing amounts larger than that may cause gastrointestinal symptoms. Cancer: Cellu-Treat is not a known carcinogen. Signs and symptoms of exposure: Symptoms of accidental over-exposure to Cellu-Treat might include nausea, vomiting, and diarrhea, with delayed effects of skin redness and peeling. Personal protection: Eye protection, protective clothing, and waterproof gloves may be necessary under certain high exposure conditions. Otherwise, refer to label for actual regulatory personal protection requirements. Occupational exposure limits: Disodium octaborate tetrahydrate (Cellu-Treat) is considered to be a nuisance dust by OSHA, Cal OSHA, and ACGIH. The OSHA/PEL is 15mg/m^3 total dust and 5mg/m^3 respirable dust. The Cal OSHA/PEL and ACGIH/TLV are 10 mg/m^3. Use local exhaust or engineering controls to prevent exceeding exposure limits if possible. SECTION III – FIRST AID MEASURES Inhalation: If symptoms such as nose or throat irritation are observed, remove person to fresh air. Eye Contact: Use eye wash fountain or fresh water to cleanse eye. If irritation persists for more than 30 minutes, seek medical attention. Skin Contact: No treatment necessary because non-irritating. Ingestion: Swallowing small quantities (one teaspoon) will cause no harm to healthy adults. If larger amounts arc swallowed, give two glasses of water to drink and seek medical attention. SECTION IV – ACCIDENTAL RELEAE MEASURES General: Cellu-Treat is a water-soluble white powder that may, at high concentrations, cause damage to trees or vegetation by root absorption. Land spill: Vacuum, shovel or sweep up Cellu-Treat and place in container for disposal in accordance with applicable local regulations. Avoid contamination of water bodies during cleanup and disposal. Spillage into water: Where possible, remove any intact containers from the water. Advise local water authority that none of the affected water should be used for irrigation or for the abstraction of potable water until natural dilution returns the boron value to its normal environmental background level. Cellu-Treat is a non-hazardous waste when spilled or disposed of; as defined in the Resource Conservation and Recovery Act (RCRA) regulations (40 CFR 261 ). SECTION V – PHYSICAL AND CHEMICAL PROPERTIES Appearance: White, odorless, powder Bulk density: 320 to 480 kg/m3 Vapor pressure: Negligible @ 200C Solubility in water: 9.7% @ 200C; 34.3% @ 500C Melting point: 8150C pH @ 20°C: 8.3 (3.0% solution) 7.6 (10.0% solution) SECTION VI – FIRE FIGHTING MEASURES AND HANDLING INSTRUCTIONS Fire Fighting Measures General Hazard: None, because Cellu-Treat is not flammable, combustible or explosive. The product is itself a flame retardant. Extinguishing Media: Any extinguishing media may be used on nearby fires. Flammability Classification (29CFR1910.1200): Non-flammable solid. General: Cellu-Treat is a stable product. Hazardous decomposition: None. Handling Instructions
