Emergency measures for Methylene Chloride

Views: 0     Author: Site Editor     Publish Time: 2022-07-01      Origin: Site

Methylene chloride can be refrigerated and used as solvent, extractant, mutagen. In the electronics industry, it is often used as a cleaning and degreasing agent. At the same time, it can be used as a dental local anesthetic, refrigerant, fire extinguishing agent, metal surface paint cleaning and degreasing agent, and film release agent, and used as an organic synthesis intermediate. So what are the emergency measures for methylene chloride? Let's take a look next.

Here is the content list:

l Emergency release treatment

l Protective measures

l First-aid

l Fire-fighting measures

Emergency release treatment

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 positive pressure air breathing apparatus. And make use of restricted spaces such as sewers and flood drainage ditches.

Small spills: Absorb or absorb methylene chloride with sand or other non-combustible material.

Large spills: Construct embankments or containment pits.

Protective measures

Respiratory protection: When the concentration of methylene chloride in the air exceeds the standard, a direct gas mask (half mask) should be worn. Wear air-breathing apparatus during emergency rescue or evacuation.

Eye Protection: When necessary, wear chemical safety goggles.

Body Protection: Wear protective clothing for infiltration of poisons.

Hand Protection: Wear chemical-resistant gloves.

Others: Smoking, eating, and drinking are prohibited at the workplace. After work, shower, and change. Store contaminated clothing separately for later use. Pay attention to personal hygiene.


Skin Contact: Remove clothing contaminated with methylene chloride and rinse skin thoroughly with soap and water.

Eye Contact: Lift eyelids, rinse with running water or saline, seek medical attention.

Inhalation: Quickly leave the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately and seek medical attention.

Ingestion: Do not give anything by mouth if the patient is about to lose consciousness, has lost consciousness, or has convulsions. Do not induce vomiting. Give the patient 250 ml of water to dilute the stomach contents. If the patient vomits spontaneously, lean forward to reduce the risk of aspiration and give water repeatedly. If breathing stops, give artificial respiration immediately by a trained person, and perform CPR if the heart stops. Quickly transport the patient to an emergency medical unit. Drink plenty of warm water, induce vomiting, and seek medical attention.

Most Important Symptoms and Harmful Effects: Exposure to very high concentrations of methylene chloride may cause loss of consciousness and death.

Protection for first-aiders: When patients inhale and swallow toxic substances, do not use mouth-to-mouth artificial respiration directly, but use a one-way air pocket mask and other medical equipment to perform artificial respiration. First aid should be performed in safe areas wearing Class C protective equipment.

Fire-fighting measures

Extinguishing methods: Mist water, sand, foam, carbon dioxide.

Extinguishing measures Applicable extinguishing media: dry chemical powder, foam, carbon dioxide, water mist.

Special hazards that may be encountered during firefighting: Methylene chloride vapor is flammable when it exceeds 120 degrees; it is dangerous to decompose toxic gases during a fire.

Special Fire Fighting Procedures: Cool exposed containers with water spray to flush spills away from exposed areas. In the event of such material on fire or in fire: Do not work to extinguish the fire unless dispersal can be stopped. If fire cannot be contained or the container is exposed to fire, the area must be evacuated within 2,500 feet; the container should be cooled with copious amounts of water until the fire is extinguished. Do not flush the spilled material directly, splashing may occur.

Special protective equipment for firefighters: Toxic products after combustion: After combustion products include toxic gases and vapors (such as hydrogen chloride, phosgene, and carbon monoxide). The vapor of methylene chloride is heavier than air and can travel considerable distances to the ignition source and burn back.
