1,4-Butanediol Safety Precautions

Section 1: Health Hazards and First Aid Measures

1. ‌Contact Routes and Hazards‌

• ‌Inhale‌: Can cause poisoning, induce respiratory irritation, and in severe cases, lead to organ damage.

• ‌Skin ContactCauses burns, allergic reactions; prolonged exposure may damage organs.

• ‌IngestedStimulate the gastrointestinal tract, causing nausea, vomiting, and even convulsions.

• ‌Eye Contact‌Severe burns and corneal damage.‌

• ‌Skin ContactRemove contaminated clothing immediately, rinse thoroughly with plenty of water for at least 15 minutes, and seek medical attention.

• ‌Eye ContactRinse with running water or生理盐水for at least 10 minutes after removing the contact lenses, continue rinsing, and seek medical attention.

• ‌InhaleMove promptly to a fresh-air area, maintain an open airway, perform artificial respiration if necessary, and seek medical attention.

• ‌IngestDo not induce vomiting. Rinse mouth with water and drink warm water immediately. Seek medical attention.

Operations and Protection Standards

1. ‌Operation Requirements‌

• Operate in a well-ventilated area and wear protective gear (respirator masks, chemical protective suits, safety goggles, and corrosion-resistant gloves).

• No eating, drinking, or smoking in the work area; avoid inhaling fumes or dust.

• Use explosion-proof equipment and keep away from flames, heat sources, and oxidizers (such as acids, strong oxidizers).

• Minor leak: Absorb with sand and dry lime, then clean up; for large leaks, construct a dike, use explosion-proof tools to collect and transfer to designated containers.

• Polluted areas must be thoroughly cleaned to prevent residues from entering the sewers or water bodies.

Section III: Storage and Transportation

1. ‌Storage Conditions‌

• Store in a cool, dry, and well-ventilated warehouse with temperatures not exceeding 30°C and relative humidity below 80%.

• Store away from oxidizers and acidic materials; avoid mixed storage.

• Utilize anti-static transportation equipment, equip with leak emergency equipment, and avoid high temperatures or excessive vibration.

• Transport vehicles must be grounded, and baffles are installed inside the tank to reduce static charge accumulation.

Fire and Emergency

1. ‌Fire Suppression Efforts‌

• Utilize carbon dioxide, dry chemical, and sand to extinguish fires; do not directly use water to冲击 liquids.

• Firefighters must wear self-contained breathing apparatus to prevent inhalation of toxic gases.

• Leakage poses a threat to aquatic life; measures must be taken to prevent water pollution and contain the spill.

Section V: Other Important Notes

• ‌Long-Term Management EngagementRegular occupational health check-ups are conducted to monitor liver and kidney function as well as skin condition.

• ‌Waste DisposalHandle as hazardous waste and entrust to professional agencies for disposal; prohibit unauthorized discharge.

The above safety measures integrate health protection, operational standards, and key emergency response points, and must be strictly adhered to in order to reduce risks.
