How Do Confined Space Gas Detector Work?

Confined spaces can be below or above ground. Confined spaces can be found in almost any workplace. A confined space, despite its name, is not necessarily small. Examples of confined spaces include silos, vats, tanks, water supply towers, sewers, pipes, boilers, manholes, pump stations, etc.

Avoiding confined spaces is always the best option. If access is needed for maintenance, inspections or other essential tasks, however, all necessary precautions must be taken. In this scenario, the safety manager should consider selecting a portable multi gas detector that is compatible with external pumps or has an internal pump, as well as the long probes or hoses used for confined space clearance measurements.

Portable multi-gas detectors usually detect and alert for four dangerous and common gasses as standard (H2S, O2, CO and Combustible Gases).

How to take a gas sample?
For taking a gas sample, a portable multi-gas detector with internal pump and gas sampling accessories such as long sampling hose and a sampling probe is needed.

It is important to take gas samples in various levels in the confined space (at the top, middle and bottom) because every level contains different gas concentrations. Gases with a high concentration are usually at the top or at the bottom of the confined space. When the gas sampling in the confined space has been completed and the atmosphere in the confined space is safe for entering one or more persons could enter the confined space.

As quick and reliable gas detect is extremely important in a confined space environment, the Confined Space Gas Detectors provides quick, precise and reliable results, and are very easy to use.
