Selection of gas detectors for use in different environments
The different working environments in daily life require gas detection, and it is important to choose a suitable and correct gas detector. This is something that every person engaged in safety and health work should pay attention to. How to choose and use a detector correctly in different environments? There are mainly two environments for use:
1, A site with openness or development potential
For example, in an open workshop, such instruments can be used as safety alarms. A portable diffusion gas detector can be used because it can continuously, real-time, and accurately display the concentration of toxic gases on site. Some of these new instruments are also equipped with vibration alarm accessories to avoid audible alarms in noisy environments, and computer chips are installed to record peak values, STEL (15 minute short-term exposure level), and TWA (8-hour statistical weight average) to provide specific guidance for worker health and safety.
2, Similar to highly enclosed or enclosed areas
For example, in workplaces such as reaction tanks, storage tanks or containers, sewers or other underground pipelines, underground facilities, agricultural enclosed granaries, railway tankers, ship cargo holds, tunnels, etc., testing must be carried out before personnel enter, and testing must be conducted outside the enclosed space. At this point, it is necessary to choose a multi gas detector with a built-in sampling pump. Because the gas distribution and types vary greatly in different parts (upper, middle, and lower) of a confined space. So a complete enclosed space gas detector should be a portable instrument with built-in pumping function for non-contact and partial detection, and multiple gas detection functions to detect hazardous gases distributed in different spaces, including inorganic and organic gases. It should have oxygen detection function to prevent hypoxia or be compact in size, without affecting the work of workers. Only in this way can the absolute safety of personnel entering confined spaces be guaranteed.
From this, it can be seen that when using gas detectors in different environments, attention must be paid to the usage method. This not only ensures safe operation, but also enables better analysis and detection reports.
