Application Notes

Here's how some of our customers used this product.

Security Sweeps of Underground Utilities

The Background: A security company must access underground utilities such as sewers and utility vaults to ensure they are clear and free from threats during large public and political events and need to monitor for accumulating gases.

The Problem: Sewers, utility vaults and other confined spaces can accumulate toxic or flammable gases making them potentially dangerous areas. As the monitors will be worn by security rather than maintenance personnel, ease of use is a primary consideration.

The Solution: The BW Technologies GasAlertMax XT II confined space kit includes all the essential tools required for confined space entry in a simple, easy-to-use kit.
