Factors to Consider Before Using a Gas Detector
1、 Before entering confined spaces and/or containers, it is necessary to check whether the work area is safe and whether corresponding arrangements need to be made, such as equipping a set of ventilation equipment, to measure the safety level of the factory. Are there any toxic or explosive substances in the area? If so, what are they? What is the oxygen level there? If the security level measurement can be implemented correctly, then these two questions can be answered. If the container has been emptied, it still plays an important role in risk assessment, regardless of whether there are pollutants releasing gases or hazardous substances entering.
Measuring the safety level of a factory requires professional knowledge in selecting and applying appropriate measurement methods. Similarly, reliable evaluation of results can only be achieved through correct professional knowledge; It is also important to provide comprehensive training and preparation.
2、 The main hazards in confined spaces are:
Formation and aggregation of explosive substances (combustible gas measurement)
Hypoxia or excessive oxygen (oxygen measurement)
Formation and aggregation of toxic substances (measurement of toxic and harmful gases)
Combustible gas measurement and oxygen measurement are mandatory measurement items.
If the oxygen concentration in the restricted area is less than 19.0 vol%, it indicates a risk of suffocation.
An oxygen concentration exceeding 23.0 vol% indicates that all substances are prone to catching fire and have high temperatures, including fire-resistant protective clothing in general environments.
