Skin contact: Remove contaminated clothing; wash skin thoroughly with soap and plenty of water; if irritation persists or develops, consult a physician
Inhalation: Move individual to fresh air immediately; if not breathing, administer artificial respiration; if symptoms occur, seek medical advice
Ingestion: Rinse mouth thoroughly, do not induce vomiting; drink water to dilute; seek immediate medical advice
Important symptoms and effects: Severe eye irritation or burns, persistent cough, nausea, redness or blistering of skin possible
Suitable extinguishing media: Water spray, dry foam, carbon dioxide, dry chemical
Unsuitable extinguishing media: Direct water jet on burning product may cause splattering; high pressure water jets increase risk of aerosols
Hazardous combustion products: Releases hazardous gases such as sulfur oxides, carbon oxides, possibly low molecular weight hydrocarbons
Protective equipment: Wear self-contained breathing apparatus and protective suit to minimize exposure to smoke and decomposition products
Additional advice: Cool containers with water spray to prevent rupture due to heat; keep runoff out of sewers and watercourses as contaminated water may cause environmental hazard
Personal precautions: Use recommended PPE, including gloves, eye protection, chemical-resistant clothing; ventilate area to avoid buildup of fumes
Environmental precautions: Prevent entry into waterways, drains, basements, or confined areas; notify authorities if a large spill enters the environment
Cleanup methods: Cover spill with inert absorbent (e.g., dry sand or earth) and collect in appropriate waste container for disposal; wash contaminated surface with plenty of water
Further advice: Avoid creating dust or aerosol, isolate area and restrict access until clean-up completed, decontaminate tools and equipment after use
Handling: Wear protective clothing as the substance can damage skin and eyes upon direct contact; keep containers tightly sealed; wash hands thoroughly after handling chemicals; avoid eating, drinking, or smoking in work area
Storage: Store in original, tightly closed containers in cool, dry, well-ventilated area away from strong oxidizers and acids; avoid temperature extremes to prevent degradation; keep away from food, beverages, and animal feed
Storage class: Corrosive materials
Incompatibles: Strong acids, strong oxidizing agents; reacts with acids releasing toxic gases
Exposure limits: No specific occupational exposure limit established for this substance; avoid continuous or prolonged exposure
Engineering controls: Provide local exhaust ventilation at points of emission to maintain airborne concentrations below recommended limits
Personal protective equipment: Safety goggles or face shield for eye protection, chemical-resistant gloves (nitrile or equivalent), impermeable apron or lab coat, suitable respiratory protection if ventilation is inadequate or dusting occurs; safety shoes for spill hazards
