| Description | Acetylene, molecular formula C2H2, commonly known as oxy-acetylene and acetylene, alkyne compound series is the smallest one, mainly for industrial use, especially welding metals. Acetylene at room temperature is a colorless, highly flammable gas. Pure acetylene is odorless, but industrial use acetylene because it contains hydrogen sulfide, phosphine and other impurities, and there was a smell of garlic. |
| Usage | Acetylene can be used to illuminate, welding and cutting of metal (oxy-acetylene flame), the basic raw material is manufactured acetaldehyde, acetic acid, benzene, synthetic rubber, synthetic fiber and the like. |
| Precautions | Inhalation: rapidly from the scene to fresh air. Maintain airway patency. If breathing is difficult, give oxygen. If not breathing, give artificial respiration immediately seek medical treatment. Respiratory protection: Most do not need special protection, but suggested that under special circumstances wear appropriate self-absorption filter respirators (oxygen content and the oxygen content of the air identical or close). Eye protection: Most do not need special protection, wearing chemical protective safety glasses high concentration exposure. Physical protection: wear anti-static clothing. Hand Protection: Wear protective gloves general operations. Other protection: no smoking scene work. Avoid prolonged and repeated contact. Into the tank, or other restrictive space of high concentration operations, someone must care. Accidental release: rapid withdrawal from air leakage personnel supremacy wind and isolation and strict restrictions on access. Cut off the fire source. Recommended emergency personnel wearing self-Pressurized respirators to wear anti-static clothing. As cut off the source of leakage. A reasonable ventilation, accelerated proliferation. Water-spray diluted solution. Build a causeway or trenching asylum produce a lot of waste water. If possible, use exhaust gas leakage sent an open area or installation of appropriate nozzle burned. Leak containers should be properly handled, repair, testing later use. |
