Confined Space

Confined spaces can be extremely dangerous—low oxygen levels, combustible gases, and toxic substances are just a few of the threats a worker may encounter. Confined space monitors can detect these hazards and more.

Confined spaces are found in a range of industries and their hazards vary from location to location. Before entering a confined space, you need to understand the regulations, obtain permits, gear up, and test the atmosphere in the space with a confined space monitor.

Even after the space has been checked and certified as safe, it’s safest to continuously use a confined space monitor for atmospheric hazards because conditions can change within moments and leave workers unaware of danger.

Continuous monitoring is simple with an area monitor like the Radius® BZ1, allowing you to eliminate the need to re-test the confined space and catch changes in environmental conditions before evacuation is necessary.

The nature of confined spaces makes communication challenging. You should equip entrants with a connected, personal confined space monitor like the Ventis® Pro5 that automatically shares alarms and gas readings from within the confined space with peers and an attendant. This connectivity lets the team continue their work without depending on manual check-ins that disrupt productivity at best and at worst, can cost someone their life if timed incorrectly.


Real-time text and email alerts through iNet® Now live monitoring provide clear visibility into gas hazards in confined spaces from anywhere, so rescuers can act quickly and effectively while avoiding further incidents.

Make sure you have access to the information you need to protect confined space workers and responders with a network of connected confined space gas monitors and the data they collect.
