Material Safety Data Sheet Section 1 Chemical Product and Company Identification MSDS Name: HOBT Product Code: 60-1002 Synonyms: 1-Hydroxybenzotriazole, N-Hydroxybenzotriazole Company identification: Severn Biotech Limited Unit 2 Park Lane Industrial Estate Kidderminster Worcestershire DY11 6TJ For information call: +44 (0)1562 825286 Section 2 - Composition, Information on Ingredients CAS: 2592-95-2 Chemical Name: 1-Hydryoxybenzotriazole %: 99 EINECS: 219-989-7 Risk Phrases: F+ - Highly flammable. R5 Heating may cause an explosion, R11 Highly flammable. Section 3 - Hazards Identification EMERGENCY OVERVIEW HIGHLY FLAMMABLE. RISK OF EXPLOSION IF HEATED UNDER CONFINEMENT. HEATING MAY CAUSE AN EXPLOSION. LIGHT SENSITIVE. Potential Health Effects Eye: May cause eye irritation. May cause chemical conjunctivitis and corneal damage. Skin: May cause skin irritation. May be harmful if absorbed through the skin. Ingestion: May cause irritation of the digestive tract. May cause nausea, vomiting, abdominal pain, and increased salivation. Inhalation: May cause respiratory tract irritation. May be harmful if inhaled. Olfactory fatigue may occur. Can produce delayed pulmonary oedema. Section 4 - First Aid Measures Eye: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Skin: Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Ingestion: Get medical aid. Wash mouth out with water. Inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Notes to Physician: Treat symptomatically and supportively. Section 5 - Fire Fighting Measures General Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode. Fire: Highly flammable solid. Explosion: Heating may cause explosion. Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or chemical foam. Section 6 - Accidental Release Measures PERSONAL PRECAUTIONS: Use proper personal protective equipment as indicated in Section 8. SPILLS AND LEAKS: Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Scoop up with a nonsparking tool, and then place into a suitable container for disposal. Avoid generating dusty conditions. Remove all sources of ignition. Provide ventilation. Section 7 - Handling and Storage HANDLING: Wash thoroughly after handling. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapour), and can be dangerous. Keep container tightly closed. Keep away from heat, sparks and flame. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. STORAGE: Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well -ventilated area away from incompatible substances. Section 8 - Exposure Controls, Personal Protection Airborne Exposure Limits: None established. Ventilation System: In general, dilution ventilation is a satisfactory health hazard control for this substance. However, if conditions of use create discomfort to the worker, a local exhaust system should be considered. Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres. Skin Protection: Wear protective gloves and clean body-covering clothing. Eye Protection: Safety glasses. Maintain eye wash fountain and quick-drench facilities in work area. Section 9 - Physical and Chemical Properties Physical State: Solid. Colour: White to off-white. Odour: Not available pH: Not available Vapour Pressure: Not available Vapour Density: Not available Evaporation Rate: Not available Viscosity: Not applicable. Boiling Point: Not available Freezing/Melting Point: 157-158oC. Decomposition Temperature: 157-158oC. Solubility in water: 0.3% in water (20oC).
