n-Octanol (octaol): colorless liquid. Has a strong aromatic smell. Density 0.83. Refractive index 1.430. Melting point -16℃. Boiling point 196℃. Not miscible with water, but miscible with ethanol, ether and chloroform. Used in making flavors and cosmetics, and as solvents, antifoaming agents, plasticizers, antifreezes, lubricating oil additives, etc. It is a by-product of making lauric acid from coconut oil. It can also be obtained by catalytically controlled polymerization of ethylene and then hydrolysis and separation.
Although n-octanol (octaol) has a wide range of uses, n-octanol also has certain dangers. Correct operation and handling must be adopted. Countermeasures, otherwise the consequences will be disastrous:
1. The dangers of n-octanol (octaol)
Health hazards: low toxicity, LD50 (rat, oral) 12.46ml/kg. This product is irritating to the eyes, skin, mucous membranes and upper respiratory tract. If it accidentally touches the skin, wipe it off immediately with a rag, use ethanol as a cleaning agent, and rinse with plenty of water.
Fire and explosion hazard: This product is flammable and irritating.
Hazardous characteristics: Combustible in case of open flame and high heat.
2. First aid measures
Skin contact: Take off contaminated clothes and rinse with plenty of running water .
Eye contact: Lift eyelids and rinse with running water or saline. Seek medical attention.
Inhalation: Leave the scene to fresh air. If breathing is difficult, give oxygen. Seek medical attention.
Ingestion: Drink enough warm water to induce vomiting. Seek medical attention.
3. Fire-fighting measures
Hazardous characteristics: Combustible in case of open flame and high heat.
Harmful combustion products: carbon monoxide, carbon dioxide.
Fire-fighting methods: Firefighters must wear gas masks and full-body fire-fighting suits, and fight fires in the upwind direction. Move containers away from the fire to an open area if possible. Spray water to keep the fire container cool until the fire is extinguished. Containers in a fire scene must be evacuated immediately if they change color or if there is sound from the safety pressure relief device.
Fire extinguishing media: mist water, foam, dry powder, carbon dioxide, sand.
4. Emergency response to leakage
Emergency response: quickly evacuate personnel from the leakage contaminated area to a safe area, They will be quarantined and access will be strictly restricted. Cut off the fire source. It is recommended that emergency responders wear self-contained positive pressure respirators and protective clothing. Cut off the source of the leak as much as possible. Prevent it from flowing into sewers, flood ditches and other restricted spaces.
Small leaks: absorb with sand, vermiculite or other inert materials. You can also use a lotion made of non-flammable dispersants for brushing. The lotion is diluted and put into the wastewater system.
Large leakage: build dikes or dig pits to contain the leakage. Use a pump to transfer it to a tanker or special collector, and recycle or transport it to a waste treatment site for disposal.
5. Handling and storage
Handling precautions: Closed operation, fully ventilated. Operators must undergo special training and strictly abide by operating procedures. It is recommended that operators wear self-priming filter gas masks (half masks), chemical safety glasses, anti-toxic substance penetration overalls, and rubber gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapors from leaking into the workplace air. Avoid contact with oxidants and acids. When handling, load and unload with care to prevent damage to packaging and containers. Equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.
Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. They should be stored separately from oxidants, acids, and food chemicals, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with leakage emergency response equipment and suitable containment materials.
