3-Methyl-2-nitrobenzoic acidFirst aid measures

First Aid:

Inhalation: If inhaled, please move the patient to fresh air.
Skin contact: Remove contaminated clothing and thoroughly rinse the skin with soap and water. If you feel unwell, seek medical attention.
Eye contact: Separate the eyelids and rinse with flowing water or physiological saline. Seek medical attention immediately.
Ingestion: Rinse mouth, do not induce vomiting. Seek medical attention immediately.

Advice for protecting rescuers:

Transfer the patient to a safe location. Consult a doctor. Show this chemical safety technical manual to the doctor on site.

3-Methyl-2-nitrobenzoic acidFire protection measures

Fire extinguishing agent:

Use water mist, dry powder, foam or carbon dioxide extinguishing agent to extinguish the fire.
Avoid using direct current water to extinguish fires, as direct current water may cause the splashing of flammable liquids and spread the fire.

Fire extinguishing precautions and protective measures:

Firefighters must wear portable breathing apparatus and full body firefighting clothing, and extinguish the fire upwind.
Move the container from the fire site to an open area as much as possible.
If the container in the fire has discolored or made a sound from the safety pressure relief device, it must be evacuated immediately.
Isolate the accident site and prohibit unrelated personnel from entering. Collect and handle fire water to prevent environmental pollution.

3-Methyl-2-nitrobenzoic acidLeakage emergency response

Protective measures, equipment, and emergency response procedures for operators:

It is recommended that emergency personnel wear portable breathing apparatus, anti-static clothing, and rubber oil resistant gloves.
Do not touch or cross the leakage.
All equipment used during work should be grounded.
Cut off the source of leakage as much as possible.
Eliminate all ignition sources.
Establish a warning zone based on the impact area of liquid flow, steam or dust diffusion, and evacuate unrelated personnel from crosswind or upwind to a safe area.

Environmental protection measures:

Collect leaked materials to avoid polluting the environment. Prevent leakage from entering sewers, surface water, and groundwater.
The storage and removal methods of leaked chemicals and the disposal materials used: Small leakage: Collect the leaked liquid as much as possible in a sealed container. Absorb with sand, activated carbon, or other inert materials and transfer to a safe location. Do not flush into the sewer. Massive leakage: Build embankments or dig pits for containment. Close the drainage pipeline. Cover with foam to inhibit evaporation. Transfer to a tank truck or dedicated collector using an explosion-proof pump for recycling or transportation to a waste disposal site for disposal.

3-Methyl-2-nitrobenzoic acidHandling and Storage

Precautions for operation:

Operators should receive specialized training and strictly follow the operating procedures.
Operation and disposal should be carried out in places with local or comprehensive ventilation facilities.
Avoid contact with eyes and skin, and avoid inhaling vapors.
Keep away from sparks and heat sources, and smoking is strictly prohibited in the workplace.
Use explosion-proof ventilation systems and equipment.
If canning is required, the flow rate should be controlled and there should be a grounding device to prevent the accumulation of static electricity.
Avoid contact with prohibited substances such as oxidants.
When transporting, it is necessary to load and unload gently to prevent damage to the packaging and containers.
Empty containers may have residual harmful substances.
Wash hands after use and prohibit eating in the workplace.
Equip corresponding types and quantities of firefighting equipment and emergency response equipment for leaks.

Storage precautions:

Store in a cool and ventilated warehouse.
It should be stored separately from oxidants and edible chemicals, and mixed storage should be avoided.
Keep the container sealed.
Keep away from sparks and heat sources.
The warehouse must be equipped with lightning protection equipment.
The exhaust system should be equipped with grounding devices for conducting and removing static electricity.
Adopting explosion-proof lighting and ventilation settings.
Prohibit the use of equipment and tools that are prone to sparks.
The storage area should be equipped with emergency response equipment for leaks and suitable storage materials.
