[Chemical Knowledge]：Specification for storage and transport of DIBK

DIBK (diisopropyl ketone) is a common raw material for chemical production. Due to its flammable and toxic characteristics, safe storage and transportation regulations are very important. This article will detail the physical and chemical properties of DIBK, hazard overview, first aid measures, fire protection measures, leakage emergency treatment, operation disposal and storage, contact control/individual protection, and physical and chemical properties.

1. physicochemical properties
DIBK is a colorless transparent liquid with a ketone taste. Relative density 0.80. Melting point -47 ℃. Boiling point 116.5 ℃. Refractive index 1.3987. Flash point (open cup) 40 ℃. Viscosity 0.78mPa · s. Vapor pressure (20°C) 1.33kPa. Heat of combustion 3212.1kJ/mol. Soluble in water, soluble in alcohol, ether and other organic solvents.

2. Hazard Overview
DIBK is flammable in case of open fire and high heat. Can react strongly with oxidants. Its vapor is heavier than air and can spread to a considerable distance at a lower point, and it will catch fire and backburn in case of a fire source. In case of high heat, the internal pressure of the container increases, and there is a risk of cracking and explosion. Hazardous combustion products: carbon monoxide, carbon dioxide.

3. first aid measures to
skin contact: immediately remove contaminated clothing and rinse skin thoroughly with soap and water. Seek medical attention.
Eye contact: Lift the eyelids and flush with flowing water or saline. Seek medical attention.
inhalation: quickly leave the scene to fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.
Intake: Drink plenty of warm water to induce vomiting. Seek medical attention.

4. fire protection measures
dangerous characteristics: flammable, its vapor and air can form an explosive mixture, fire, high heat caused by combustion and explosion. Can react strongly with oxidants. Its vapor is heavier than air and can spread to a considerable distance at a lower point, and it will catch fire and backburn in case of a fire source.
harmful combustion products: carbon monoxide, carbon dioxide.
fire extinguishing method: move the container from the fire to the open area as much as possible. Spray water to keep the fire container cool until the end of the fire. Containers in a fire scene that have discolored or produced sound from the safety pressure relief device must be evacuated immediately. Fire extinguishing agent: anti-soluble foam, dry powder, sand. Fire extinguishing with water is ineffective.
Emergency treatment of
5. leakage
Emergency treatment: quickly evacuate personnel from the leakage pollution area to the safety zone, isolate them, and strictly restrict access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and anti-static overalls. Cut off the leak source as much as possible. Prevent from flowing into restricted spaces such as sewers and flood drainage ditches. Small amount of leakage: adsorption or absorption with sand or other non-combustible materials. Can also be washed with a lot of water, wash water diluted into the waste water system. Large leakage: build embankments or dig pits to contain. Cover with foam to reduce steam disasters. Transfer to tank truck or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.

6. Operation Disposal and Storage
Operation Precautions: Closed operation, full ventilation. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that the operator wear a filtering gas mask (half mask), chemical safety protection glasses, anti-static work clothes, and rubber and 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 leakage into the workplace air. Avoid contact with oxidizing agents. When filling, the flow rate should be controlled, and there is a grounding device to prevent static accumulation. Handle lightly to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may leave harmful substances. Precautions for
storage: Store in a cool and ventilated warehouse. Keep away from fire and heat source. The warehouse temperature should not exceed 30 ℃. Keep container sealed. Should be stored separately from the oxidant, do not mix storage. Explosion-proof lighting and ventilation facilities shall be adopted. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.

7. Exposure Control/Personal Protection
Occupational Exposure Limit: China MAC(mg/m3): No Standard; Former Soviet Union MAC(mg/m3): No Standard; TLVTN: No Standard; TLVWN: No Standard; Monitoring Method: Engineering Control: Closed Operation, Full Ventilation; Respiratory System Protection: When the concentration in the air exceeds the standard, wear a filtering gas mask (half mask); eye protection: wear chemical safety protection glasses; body protection: wear anti-static work clothes; hand protection: wear rubber oil-resistant gloves; other protection: smoking is strictly prohibited on the work site. Maintain good hygiene habits. Physical and chemical properties of
