Precautions before using a gas detector
1. Measure the safety level of the factory Before entering the confined space and/or the container, it is necessary to check whether the working area is safe and whether corresponding arrangements are required, such as a set of ventilation equipment. Are there any toxic or explosive substances in the area, and if so, what substances? How much oxygen is there? These two questions can be answered if security level measurements can be implemented correctly. If the container has been completely emptied, it still plays an important role in the risk assessment, regardless of the presence of outgassing pollutants or the ingress of hazardous substances.
Measuring plant security levels requires expertise in selecting and applying appropriate measurement methods. Likewise, results can only be reliably assessed with the right expertise; thorough training and preparation are also important.
2. The main reasons for the danger in the confined space are:
Formation and accumulation of explosive substances (combustible gas measurement)
Hypoxia or hyperxia (oxygen measurement)
Formation and accumulation of toxic substances (measurement of toxic and harmful gases)
Combustible gas measurement and oxygen measurement are mandatory measurement items.
Oxygen concentrations of less than 19.0vol% in confined areas indicate a suffocation hazard.
When the oxygen concentration exceeds 23.0vol%, it means that all substances are prone to fire, and the temperature of the substance is high, including fire-resistant protective clothing in general environments.
