In recent years, gas alarms have become more and more widely used, especially in the autumn and winter seasons in the north, which are dry and rainy. Always pay attention to the safe production of chemical production workshops. However, according to reports, accidents caused by explosions or leaks of flammable or toxic gases continue to increase every year, among which A large part of it stems from the illegal production of enterprises and the dirty and poor production environment, resulting in frequent accidents. Generally, an effective way to solve gas leaks or explosions is to install gas alarms. So what are portable gas detectors and gas detectors? How is it applied to production?
Because portable instruments are easy to operate and small in size, they can be carried to different production areas. Electrochemical detectors are powered by alkaline batteries and can be used continuously for hours. New detectors and composite instruments use rechargeable batteries (some have been Using memoryless nickel-metal hydride or lithium-ion batteries), they can generally work continuously for nearly an hour. Therefore, such instruments are increasingly used in various factories and health departments.
If this type of instrument is used as a safety alarm in an open place, such as an open workshop, you can use a body-worn diffusion gas detector because it can continuously, real-time and accurately display the toxic and harmful gases on site. concentration. Some of these new instruments are equipped with vibrating alarm attachments to avoid inaudible alarms in noisy environments, and are equipped with computer chips to record peak values (minute short-term exposure levels) and (hourly statistical weighted averages) for worker health. and provide specific guidance on safety.
If you are entering a confined space, such as a reaction tank, storage tank or container, sewer or other underground pipeline, underground facility, agricultural closed granary, railway tanker, shipping cargo hold, tunnel and other workplaces, you must Testing must be done before people enter, and testing must be done outside the confined space. At this time, it is necessary to choose a multi-gas detector with a built-in sampling pump. Because the gas distribution and gas types in different parts (upper, middle, and lower) of the confined space are very different. For example: Generally speaking, the specific gravity of combustible gases is relatively light, and most of them are distributed in the upper part of the confined space. The specific gravity of carbon monoxide and air are similar, and they are generally distributed in the middle of the confined space, while heavier gases such as hydrogen sulfide exist in the confined space. Lower part (as shown in the picture). At the same time, oxygen concentration is also one of the types that must be detected. In addition, if the possible volatilization and leakage of organic substances in the tank are considered, a detector that can detect organic gases is also needed. Therefore, a complete confined space gas detector should have a built-in pumping function so that it can detect non-contact and divided parts. It should have a multi-gas detection function to detect dangerous gases distributed in different spaces, including inorganic gases and organic gases, and an oxygen detection function to prevent It is a portable instrument for hypoxia or oxygen enrichment that is compact and does not affect workers' work. Only in this way can the absolute safety of workers entering confined spaces be guaranteed.
In addition, after entering a confined space, the gas components must be continuously detected to avoid volatile organic compounds or other toxic and harmful gases caused by personnel entry, sudden leaks, temperature changes, etc. concentration changes. With the rapid development of industry, there are more and more occasions where humans are exposed to harmful gases, which has caused greater and greater harm to humans themselves. Poisoning accidents have made people soberly aware of the importance of protecting the environment while developing industry. importance of human safety. Therefore, various harmful gas alarms have gradually become indispensable protective equipment in industrial safety production.
Be careful when choosing combustible gas alarms and toxic gas alarms. Choose a brand with complete formal certificates and rest assured!
