The factors that affect the alarm value of the gas detector are the knowledge brought to everyone today. The gas detector can effectively distinguish the molecular structure of toxic gases and make predictions, but sometimes there are some factors that affect the alarm value of the gas detector. Let's take a look.

1. Protection level of personnel

The working area of some toxic and harmful gases requires special requirements for workers to wear necessary protective tools. For example, in tunnel excavation projects, the alarm value of toxic gas detectors should be set according to the level of protective measures taken by the staff in these working areas with low air circulation. If the protection is weak, it is recommended to set two levels: forecast level and alarm level.

2. Toxic gas concentration

The petroleum industry, chemical industry and pharmaceutical industry are full of all kinds of toxic and harmful gases, so these industries must match the cost-effective toxic gas detector. In addition, in the actual processing plant, it is recommended that operators measure the concentration of toxic gas in advance, and match the corresponding alarm value according to this concentration index. Generally speaking, these areas should be set as high reporting level according to the standard.

3. Ventilation and exhaust facilities

The setting of the alarm value of the toxic gas detector can also refer to the ventilation and exhaust conditions of the on-site operating environment.For example, if there are large quantities of ventilation and exhaust facilities for the excavation of long tunnels in deep mountains, the probability of poisoning and hypoxia of construction personnel can be greatly reduced. Of course, although the ventilation and exhaust facilities are good, construction personnel also need to set the alarm value of toxic gas detectors according to the specific tunnel construction environment, so as not to evacuate quickly when a large amount of toxic gas is diffused.
