5-Chloro-2-methylaniline leakage treatment method
Isolate the leakage pollution area, and set up warning signs around it. It is recommended that emergency personnel wear self-contained breathing apparatus and chemical protective clothing. Do not touch the spilled material directly, collect it in a dry, clean, covered container with a clean shovel, and transport it to a waste disposal site. If a large amount of 5-chloro-2-methylaniline leaks, it should be collected and recycled or disposed of after harmless treatment.

1. Emergency treatment of leakage

Quickly evacuate personnel from the leaked contaminated area to a safe area, isolate them, and strictly restrict access. Cut off the source of ignition. It is recommended that emergency responders wear self-contained breathing apparatus and protective clothing. Do not directly touch the leakage, cut off the source of leakage as much as possible, and prevent entry into restricted spaces such as sewers and flood drains.

Small leakage of 5-chloro-2-methylaniline: Absorb or absorb with sand or other non-combustible materials. It can also be washed with plenty of water, diluted with the washing water and put into the waste water system.

Large spills of 5-chloro-2-methylaniline: Construct embankments or dig pits for containment. Cover 5-chloro-2-methylaniline with foam to reduce vapor hazards. Transfer it to a tanker or a special collector with a pump, and recycle it or transport it to a waste disposal site for disposal.

Waste disposal method: Use controlled incineration. Nitrogen oxides from incinerators are removed by scrubbers or high temperature units.

2. Protective measures

Respiratory protection: Wear a filter gas mask (half mask) when exposed to 5-chloro-2-methylaniline vapor. Wear isolation respirators during emergency rescue or evacuation.

Eye Protection: Wear safety glasses.

Body Protective Clothing: Wear protective overalls.

Hand Protection: Wear rubber gloves.

Others: Smoking, eating and drinking are prohibited at the workplace. Change and wash work clothes in time. Do not drink alcohol before and after work, and bathe with warm water. Be careful to detect poisons. Conduct pre-employment and regular physical examinations.

3. First aid measures

Skin contact with 5-chloro-2-methylaniline: Immediately remove contaminated clothing and rinse skin thoroughly with soap and water. seek medical attention.

Eye contact with 5-chloro-2-methylaniline: Lift the eyelids and flush with running water or normal saline. seek medical attention.

Inhalation of 5-chloro-2-methylaniline: Quickly remove from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. seek medical attention.

Ingestion of 5-chloro-2-methylaniline: Drink enough warm water to induce vomiting. seek medical attention.

Extinguishing methods: Extinguishing media: water mist, foam, carbon dioxide, dry powder, sand.
