How to choose a gas detector in different environments
For the requirements of gas detection in different working environments in life, 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.
How to choose and use the detector correctly in different environments? Xiaobian mainly uses the following two environments:
1. An open or development 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 statistically weighted average value). ) provide specific guidance on worker health and safety.
2. Similar closed or airtight places
For example, reaction tanks, storage tanks or containers, sewers or other underground pipelines, 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 be a gas detector with a built-in pumping function for non-contact and sub-site detection. It has a multi-gas detection function to detect dangerous gases distributed in different spaces, including inorganic gases and organic gases. It has an oxygen detection function. It is a portable instrument that prevents hypoxia or enrichment and 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.
