(2) When gas operators work in the gas area, they should first check the gas concentration. When the gas concentration exceeds 30mg/m3 and is lower than 200mg/m3, ventilation or air supply measures should be taken to reduce the gas concentration and shorten personal working hours. When the gas concentration exceeds 200 mg/m3, two or more people must wear air respirator to work together. (3) When the equipment is overhauled, all air sources must be reliably cut off. When workers enter the gas area, they must check whether the gas content in the air in the work area is qualified: when workers work, the area should have strong ventilation facilities; In a workplace, there must be more than two people working, one working and the other supervising.
(4) Establish a gas content detection system in the air in the gas area, strengthen daily spot checks, find gas leakage points in time, stop leakage as soon as possible, achieve early detection and early treatment, avoid the increase of leakage points, and introduce a large area of gas concentration exceeding the standard.
(5) Combined with the seasonal characteristics of gas poisoning, prevention work should be organized in a targeted manner.
A. Before winter and in winter and spring, check the gas pipeline (equipment) for "running, leaking, dripping and leaking". If so, it should be solved as soon as possible. Comprehensively check whether the fixed-point gas detectors located in gas cabinets, hot stoves and other areas are sensitive and reliable, so as to ensure the normal operation of the detection instruments. Check the safety warning signs in the gas area comprehensively, and fill them as soon as possible if the signs are incomplete. Because of the high temperature of many gas equipment, the floating people in the factory are not clear about the environment, and they are likely to choose to rest in these parts, thus creating danger.
B most of the gas pipeline drains are located in the open air, and the ambient temperature is relatively low in winter. Once the management is not in place, it is easy to go wrong. The following inspection work should be done well: firstly, always check whether the heat preservation facilities of the drainer are operating normally, and adjust the steam quantity in time according to the specific situation to ensure the temperature required for heat preservation; Secondly, check whether the drainer has been overflowing to prevent air leakage caused by water shortage; Third, check whether the valves of all parts are in good condition and in normal open or closed positions to ensure the normal operation of water supply, drainage and insulation systems.
C a large part of ladders and platforms in the gas system are located outdoors, so it is necessary to carefully check whether these facilities are in good condition in winter. The high gas platform should be equipped with an accident slide to facilitate rapid evacuation when the gas concentration exceeds the standard.
Dangerous area.
D Because workers wear more clothes when working in the open air in winter, the scene environment is relatively narrow, which is likely to bring inconvenience to the operation. In addition, due to the low temperature, the reaction is slower than usual when working in the open air. Therefore, workers should be educated in winter production safety, and training materials should be compiled according to the characteristics of winter season and the lessons of past accidents, so as to organize workers to learn and improve their ability to resist risks.
(6) When the enterprise carries out technical transformation, the workshop layout should be reasonable to avoid workers' workplaces being surrounded by gas systems. In the working area where gas leakage is easy to occur, a gas alarm device should be set up.
(7) Enterprises must establish gas rescue stations, equip them with emergency rescue equipment, formulate emergency rescue plans for gas poisoning accidents, and conduct regular drills. This will play a very important role in the first aid of gas poisoning and avoiding the expansion of accidents ~
