Hazardous characteristics of n-heptane 99.5%:

Flammable, its vapor is heavier than air. It can form an explosive mixture with air at room temperature.

Health hazards: Irritating to the skin. Long-term contact through inhalation can cause serious harm. Ingestion is harmful to the lungs, and its vapor can cause coma.

Environmental hazards: Highly toxic to aquatic organisms and can have long-term adverse effects.

Explosion hazard: Highly flammable

Operation, disposal and storage of n-heptane 99.5%:

Operation precautions: Closed operation and comprehensive ventilation. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear filter-type gas masks (half masks), safety glasses, anti-static work clothes, and rubber oil-resistant gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapor from leaking into the workplace air. Avoid contact with oxidants. The flow rate should be controlled during filling, and there should be grounding devices to prevent static electricity accumulation. Equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may contain harmful substances.

n-Heptane 99.5% Storage Precautions: Store in a cool and ventilated warehouse. Keep away from fire and heat sources. The warehouse temperature should not exceed 30℃. Keep the container sealed. It should be stored separately from oxidants and should not be mixed. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and appropriate containment materials.
