Hazard Overview
| Hazard Class | Class 2.1 Flammable Gas (21045) |
| Route of Entry | Inhalation, Ingestion, Skin Absorption |
First Aid Measures
| Skin Contact | Remove contaminated clothing and immediately rinse with plenty of water for 15 minutes, then rinse with a 2.5% boric acid solution. Seek medical attention if severe. |
| Eye Contact | Immediately lift eyelids and rinse with plenty of water for 15 minutes, then rinse with a 2.5% boric acid solution. Seek medical attention if severe. |
| Inhalation | Quickly move to fresh air and keep warm. If conscious, provide hot sweet tea. If breathing is difficult, administer oxygen; if breathing stops, perform artificial respiration immediately and send to hospital. |
| Ingestion | Rinse mouth immediately, drink plenty of milk and water, induce vomiting, and seek medical attention. |
Firefighting Measures
| Fire Extinguishing Methods and Agents | Cut off power supply, use water spray, foam, carbon dioxide, or dry powder to extinguish fire. |
| Firefighting Precautions | Firefighters should wear protective clothing and extinguish fire from a safe distance upwind, using anti-toxic masks or self-contained breathing apparatus. If the gas source cannot be immediately cut off, do not extinguish the burning gas. |
Leak Emergency Response
| Emergency Response | First, cut off ignition sources to prevent combustion and explosion. Then, cut off the leak source and quickly evacuate personnel from the contaminated area to a safe upwind location for plugging (wear protective clothing and anti-toxic masks or respirators). Notify authorities if necessary. |
| Cleanup Methods | Collect leakage in containers as much as possible (preferably sealed pressure-resistant containers). Alternatively, slowly introduce the leak into a container with hydrochloric acid or water, or spray water to dilute and dissolve, and construct dikes or pits for containment. Then transfer using explosion-proof pumps to prevent entry into water bodies. For small leaks, ventilate or exhaust to disperse quickly. |
Handling and Storage
| Handling Precautions | Operators must undergo strict training and strictly follow operating procedures. Ensure ventilation on site and strictly prohibit open flames. Operators should wear personal protective equipment, handle with care during搬运, and operate in a sealed manner. |
Stability and Reactivity
| Stability | Stable |
| Incompatible Materials | Strong oxidizers (such as concentrated nitric acid), mercury, halogens, acids, chlorine. |
| Conditions to Avoid | Air, open flames, high heat. |
| Polymerization Hazard | Will not occur. |
| Decomposition Products | Carbon monoxide, carbon dioxide, nitrogen oxides, nitrogen, water, etc. |
Disposal Considerations
| Disposal Methods | Slowly add to hydrochloric acid, control at low temperature to fully form methylamine hydrochloride until pH is 6, then safely landfill by deep burial, or dilute with excess water and discharge into wastewater system or undergo further treatment. |
| Disposal Precautions | Do not add strong alkali to methylamine hydrochloride, otherwise methylamine will be released again. |
