What type of exposure does an LHG's gas detection system aim to monitor?

The gas detection system in a liquefied hazardous gas (LHG) facility is primarily designed to monitor workers' exposure to toxic gases. This is crucial because LHGs can be potentially dangerous; they may release toxic fumes during leaks or accidents, which pose significant health risks to personnel. The system works by detecting the presence of specific toxic gases in the environment where workers are operating, allowing for early warning and protective measures to be enacted.

Monitoring workers' exposure ensures that safety protocols are maintained to protect health and minimize the risk of incapacitating health effects from hazardous substances. Continuous monitoring supports regulatory compliance and helps create a safer workplace by alerting workers and management to potentially hazardous conditions.

The focus on toxic gas exposure differentiates this type of detection system from other options, like monitoring only flammable gases, assessing general air quality, or measuring temperature fluctuations, which are not the primary purpose of an LHG gas detection system.
