fire fighting
Dangerous characteristics
Diethyl adipate is flammable in case of open fire and high heat. Decomposition at high temperature gives off irritating smoke.
Harmful combustion products
Carbon monoxide, carbon dioxide.
Fire extinguishing method
Firefighters must wear gas masks and full-body fire suits to put out the fire in the upwind direction. Move the container from the fire to an empty place as much as possible. Spray water to keep the burning container cool until the fire goes out. If the container in the fire changes color or the safety pressure relief device sounds, it must be evacuated immediately. Extinguishing agent: atomized water, foam, dry powder, carbon dioxide, sand.
Emergency treatment of leakage
Emergency treatment
Quickly evacuate the personnel in the leaked and polluted area to a safe area, isolate them, and strictly restrict access. Cut off the fire. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and protective clothing. Cut off the leakage source as much as possible. Prevent it from flowing into confined spaces such as sewers and flood discharge ditches. Small amount of leakage: Brush with emulsion made of incombustible dispersant, dilute the lotion and put it into wastewater system. A large number of leaks: damming or digging holes to contain them. Pump it into a tanker or a special collector, and recycle it or transport it to a waste disposal site for treatment.
Operation, disposal and storage
Precautions for operation
Closed operation, pay attention to ventilation. Operators must be specially trained and strictly abide by the operating procedures. Operators are advised to wear self-priming filter gas mask (half mask), chemical safety glasses, breathable work clothes and rubber oil-resistant gloves. Stay away from kindling and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation system and equipment. Prevent the steam in the workplace from leaking into the air. Avoid contact with oxidants, acids and bases. When handling, handle with care to prevent the packaging and containers from being damaged. Equipped with corresponding varieties and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may leave harmful substances behind.
Precautions for storage
Store in a cool and ventilated warehouse. Stay away from fire and heat sources. Should be stored separately from oxidants, acids, alkalis and edible chemicals, and should not be mixed. Equipped with corresponding varieties and quantities of fire fighting equipment. The storage area should be equipped with emergency response equipment for leakage and suitable accommodation materials.
Contact control/personal protection
engineering control
Closed operation, pay attention to ventilation.
Respiratory system protection
When the concentration of diethyl adipate in the air exceeds the standard, you must wear a self-priming filter gas mask (half mask). Air respirator should be worn during emergency rescue or evacuation.
Eye protection
Wear chemical safety glasses.
Physical protection
Wear anti-virus infiltration overalls.
Hand protection
Wear rubber oil-resistant gloves.

Matters needing attention in transportation
Diethyl adipate should check whether the packaging container is complete and sealed before transportation to ensure that the container does not leak, collapse, fall or be damaged during transportation. It is forbidden to mix with oxidant, acid, alkali and edible chemicals. Transport vehicles and boats must be thoroughly cleaned and disinfected, otherwise other items may not be shipped. During shipment, the assembly position should be far away from the bedroom and kitchen, and isolated from the engine room, power supply, fire source and other parts. Highway transportation should follow the prescribed route.
