There are occupational exposure limits, but is it necessary to install toxic gas detection alarms for those not required by the regulations?

Many liquids or gases have occupational exposure limits, and those limits are quite low. However, the regulations do not require the installation of detectors or alarms for toxic gases – do you install such devices? In that case, it is necessary to **increase** the types of substances for which gas detection alarms need to be set up
This needs to be determined based on your organization’s \"Occupational Health Control Effect Evaluation\" report, taking into account compliance assessments and monitoring of occupational hazards in the workplace.
Article 2.0.2 of GBT 50493-2019 \"Design Standard for Detection and Alarm of Flammable and Toxic Gases in Petrochemical Industries\": Toxic gases refer to toxic gases or vapors that can cause death or permanent injury to workers during their occupational activities through skin contact or inhalation. Explanation of the provisions: Any gas that can cause death or permanent injury through skin contact or inhalation is considered a toxic gas. All must comply with these specifications.
The explanatory text indeed says that, it’s complete nonsense
Yes, especially in new projects these days, there are many such toxic gas sensor settings. Let’s see if older companies will issue any further explanations in the future
