Chemical Name: Benzoic Acid
Concentration: ≥99% (pure substance)
Components: Benzoic Acid only, with minimal impurity traces based on manufacturing process
Impurities: Trace amounts of water, organic byproducts can rarely appear, verified by laboratory analysis
Other Additives: None reported in standard chemical-grade product
Inhalation: Remove exposed individual to fresh air. Seek medical attention for any breathing discomfort. If breathing has stopped, provide artificial respiration.
Skin Contact: Remove contaminated clothing. Wash affected area thoroughly with soap and water. Seek medical help if irritation persists.
Eye Contact: Rinse cautiously with water for at least 15 minutes, holding eyelids apart. Remove contact lenses if present and safe to do so. Go to a medical professional for further evaluation.
Ingestion: Rinse mouth. Do not induce vomiting. Get immediate medical advice. Never give anything by mouth to an unconscious person.
Suitable Extinguishing Media: Use foam, dry chemical, carbon dioxide, or water spray. Water spray can help cool containers exposed to flames.
Specific Hazards: Thermal decomposition can release toxic fumes such as carbon monoxide and carbon dioxide.
Protective Equipment: Firefighters use self-contained breathing apparatus and full protective clothing.
Explosion Data: Dust can form explosive mixtures with air, take steps to avoid dust formation near ignition sources.
Personal Precautions: Use personal protective gear including gloves, safety goggles, and respiratory protection to minimize exposure.
Environmental Precautions: Prevent further leakage if possible, avoid letting product reach drains or watercourses.
Methods for Cleanup: Sweep up material carefully to avoid creating dust clouds; collect in suitable containers for disposal. Ventilate the area, wash residue with water ensuring it does not enter sewage systems directly.
Handling: Operate in a well-ventilated environment. Avoid breathing dust or fumes, avoid contact with eyes and skin. Use proper lifting techniques for heavy containers.
Storage Conditions: Store in tightly closed containers, in a cool, dry area away from incompatible substances like strong oxidizers. Avoid heat sources and direct sunlight. Store at room temperature below 30°C.
Incompatible Materials: Strong bases, strong oxidizing agents.
Exposure Limits: ACGIH TLV: 10 mg/m³ (inhalable fraction). OSHA PEL: not established.
Engineering Controls: Local exhaust ventilation, safety showers and eyewash stations in workplace.
Personal Protection: Safety goggles, chemical-resistant gloves (nitrile, neoprene), lab coats or aprons, NIOSH-approved particulate respirators for dusty conditions.
Hygiene Measures: Wash hands and exposed skin after handling, do not eat or drink in work area, remove contaminated clothing immediately.
