Gas Leak Detectors in Confined Spaces
With limited entrance and exit points, confined spaces are dangerous environments that pose many potential hazards to workers. They’re typically poorly ventilated and can contain several hazardous fumes, gases, or lack of oxygen that may cause illness or even death. Co detector are especially dangerous for workers who enter them for maintenance or other purposes.
Before the availability of portable gas detectors, finding a leak was a detective-like task. Technicians might be able to hear one (if background noise didn’t drown it out), or they might use pressure gauges or sniffers to identify the source. They might also look for bubbles or work their way down a pipe, hoping to find the spot of a leak.
Gas Leak Detectors in Confined Spaces: Protecting Lives
Today, workers entering a confined space are equipped with personal multi-gas monitors that not only ensure they’re wearing appropriate PPE and following proper safety protocols before entry, but that they can continuously track atmospheric conditions throughout the entry and exit of a confined space. This allows them to quickly notice when conditions are trending toward danger and introduce ventilation before they become life-threatening.
The meter display on a personal multi-gas monitor shows the concentration of a gas in the air, with a scale representing its Lower Explosive Limit (LEL) and Upper Explosive Limit (UEL). Methane, for instance, is displayed as 5% LEL. If the UEL is reached, it’s possible for methane to ignite and explode. A worker’s gas detector will alert them if the concentration of a combustible gas approaches its UEL, mitigating the risk of ignition.
