How to choose a suitable gas detector in different environments?
1. An open or developmental site
For example, if such an instrument is used as a safety alarm in an open workshop, a wearable 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 hearing the audible alarm in noisy environments, and install computer chips to record peak, STEL (15-minute short-term exposure level) and TWA (8-hour statistical weighted average value). ) provide specific guidance on worker health and safety.
the
For example, reaction tanks, storage tanks or containers, sewers or other underground pipes, underground facilities, agricultural closed granaries, railway tank cars, shipping cargo holds, tunnels and other workplaces must be tested before personnel enter, and must be in a confined space testing outside. At this point, 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) in the confined space are very different.
Therefore, a complete gas detector in a confined space should have a built-in pumping function for non-contact, sub-site detection with a multi-gas detection function to detect dangerous gases distributed in different spaces, including inorganic gases and organic gases. Oxygen detection The function is to prevent hypoxia or enrichment. It is a portable instrument that is small in size and does not affect the work of workers. Only in this way can the absolute safety of the staff entering the confined space be guaranteed.
It can be seen that when we use gas detectors in different environments, we must pay attention to the way of use, so that we can not only ensure safe work, but also better make correct analysis and test reports. After all, different working environments in life have different requirements for gas detection. Therefore, it is necessary to choose a suitable and correct gas detector. This is something that every person engaged in safety and health work should pay attention to.
