Gas detector is a gas detector widely used in petrochemical, environmental protection, metallurgy, coal mine, pharmaceutical and other industries. However, due to the different application environment and detection requirements, the types of gas detectors are also different. For the safety of personnel, we must learn to choose the appropriate gas detector in different environments. So do you know how to choose a suitable gas detector in different environments? 1. With open or developmental sites
For example, open workshops use such instruments as safety alarms, and wearable diffusion gas detectors can be used because it can continuously, real-time and accurately display the concentration of toxic gases on site. Some of these newer instruments also come with a vibration alarm attachment to avoid audible alarms in noisy environments, and a computer chip to record peaks, STEL (15-minute Short Term Exposure Level) and TWA (8-hour Statistically Weighted Average) ) provides specific guidance on worker health and safety.
2. Similar to a relatively strong or closed site
Such as reaction tanks, storage tanks or containers, sewers or other underground pipelines, underground facilities, agricultural closed granaries, railway tankers, shipping cargo holds, tunnels and other workplaces, before personnel enter, they must be tested, and in confined spaces test outside. At this point, a multi-gas detector with a built-in sampling pump must be selected. Because the gas distribution and gas types in different parts (upper, middle and lower) in the confined space are very different.
Therefore, a complete confined space gas detector should be a gas detector with built-in pumping function so that it can detect non-contact and sub-site with multi-gas detection function to detect dangerous gases with different spatial distributions, including inorganic gases and organic gases. Oxygen detection Function to prevent hypoxia or enrichment. Small size, portable instrument that 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, which can not only ensure safe work, but also make better 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.
