Confined space gas monitors are often referred to as multi-gas detectors or 4 gas monitors. It is equipment for confined space businesses to mitigate risks relating to the hazardous atmosphere such as gas leaks or toxic air. The gas monitors utilize an internal pump to pull the gas sample into the system and should be used before entering a confined space and continue to monitor throughout the process.
Defining Confined Spaces
A confined space is an area that is not easy to enter or escape. Confined spaces have limited entry methods and are not meant for long-term occupancy. A permit-required confined space has specific entry requirements from the OSHA for safety concerns.
Definition of Confined Spaces from the Occupational Safety and Health Standards
- A confined space is large enough and configured for an employee to physically enter and perform their assigned work
- It has limited or restricted means for entry or exit, such as tanks, vessels, silos, storage bins, hoppers, vaults, and pits
- A confined space is not designed for continuous occupancy
Confined Space Gas Monitors Functions
Confined spaces are one of the most dangerous environments technicians or emergency personnel can encounter. A confined space containing toxic, corrosive, or combustible gasses accumulates easily, causing immediate harm to anyone who accesses the space. A confined space gas monitor is designed to detect atmospheric hazards that are potentially present on a job site at levels below the exposure limits. Understanding the system’s function can help determine which gas monitors are suitable for you. For example, gas detectors with sampling probes and extension hoses allow quick gas detection from a distance before entering a confined space. Here is a quick overview of gas monitors’ specifications and the gasses they are capable of testing:
Important Specifications
- Alarm/alert systems
- Pump type
- Sensor types and accuracy
- IP ratings
- Battery life
Common Gas Types
- Carbon Monoxide (CO)
- Combustible Gas (LEL)
- Hydrogen Sulfide (H2S)
- Oxygen (O2)
Confined Space Gas Monitors Applications
Choosing the right confined space gas monitor is important in order to mitigate the risks and complete the appropriate testing requirements. A multi-gas monitor for confined space applications requires functions to test the space before entry and measure continually while in the space. The system needs to be easy to use and reliable for emergencies.
