| SYMPTOMS | PREVENTION | FIRST AID | |
| Inhalation | Cough. Sore throat. | Use local exhaust or breathing protection. | Fresh air, rest. |
| Skin | Redness. Burning sensation. Itching. | Protective gloves. | Remove contaminated clothes. Rinse and then wash skin with water and soap. |
| Eyes | Redness. Pain. | Wear safety goggles. | First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. |
| Ingestion | Abdominal pain. Nausea. Vomiting. | Do not eat, drink, or smoke during work. Wash hands before eating. | Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention . |
| Using methyl mercaptan as raw material, continuous reaction with chlorine gas in hydrochloric acid aqueous solution, the hydrogen chloride gas produced by the reaction makes the material produce turbulence, so that the reactants flow in the mixing reactor composed of rising film reactor (tubular heat exchanger) and full mixing reactor in the way of piston flow and full mixing flow, full contact and reaction, and timely removal of the heat generated by the reaction, maintain a low reaction In response to the temperature, the material produced by the reaction is washed, absorbed and separated by sedimentation stratification and spray of low temperature methyl sulfonyl chloride. The product methyl sulfonyl chloride and by-product hydrogen chloride gas are removed |
Frequently Asked Questions
Q: How dangerous is Methanesulfonyl Chloride?
Health Hazards: It can be inhaled, ingested, or absorbed through the skin. This product is highly irritating to mucous membranes, upper respiratory tract, eyes and skin. Inhalation can cause spasm, edema, and inflammation of the larynx and bronchi.
Environmental Behavior: Combustible in case of fire or high heat. Reacts with strong oxidizing agents. Decomposed by high heat produces toxic and corrosive gases. The product of decomposition after combustion is hydrogen chloride.
Q: The leakage treatment?
A: Evacuate the personnel in the leaked contaminated area to a safe area, and prohibit irrelevant personnel from entering, and turn off the source of ignition. It is recommended that emergency personnel wear self-contained breathing apparatus and chemical protective clothing. Stop the leakage under the condition of ensuring safety and do not touch the leakage directly. Spray out a mist of water to reduce evaporation. Mix and absorb with sand or other non-combustible adsorbents, then collect and transport to the waste treatment site for disposal. It is also possible to scrub with emulsion made of non-combustible dispersant and put diluted wash water into the wastewater system. If there is a large amount of leakage, use dikes to contain it, and then collect, transfer, recycle or discard it after harmless treatment.
Q: Protective measures?
A: When the concentration in the air exceeds the standard, you need to wear a gas mask. Wear self-contained breathing apparatus during emergency rescue or escape. Wear chemical safety goggles and overalls (made of anti-corrosion materials). Wear rubber gloves. Take a shower after work and pay attention to personal hygiene. Store poison-contaminated clothes separately and wash them before using them.
Q: First-aid measures?
Take off contaminated clothing immediately, wash the contact point thoroughly with plenty of water and soapsuds, and seek medical advice in time if burns.
Immediately lift the eyelids and rinse thoroughly and persistently with plenty of running water or normal saline at least 15 minutes. Seek medical attention.
Get out of the scene and into the fresh air. Keep airway open. Give mouth to mouth resuscitation if it is necessary. Seek medical attention.
If swallowed by mistake, rinse his or her month immediately as soon as the patient is conscious, and drink milk or egg whites. Seek medical attention.
Use dry powder, carbon dioxide, sand, foam to extinguish fire.
