The FireBag® provides a passive gas safety shutoff by automatically stopping the flow of gas when exposed to fire. When ambient temperatures reach 203˚-212˚F, the automatic shut off device closes, thus preventing the flow of gas from feeding a fire and averting larger scale incidents. Significant safety improvements are achieved without the need for expensive actuators, electrical power heat detectors, or fire detectors. And at last, natural gas utilities and propane companies now can provide evidence of a positive gas shutoff when fire occurs, while increasing safety by further protecting lives, property and first responders.
TECO SRL (Italy) developed the FireBag as an automatic and reliable thermal activated shutoff (TAS), based on extensive experience in Germany, where thermal gas shutoff devices have been required in homes since the ’90’s. The FireBag currently protects millions of homes worldwide and now. TECO America’s is pleased to be introducing this revolutionary technology to North America.
How the FireBag Works
The FireBag Thermal Activated Shutoff (TAS) consists of a zinc-plated steel fitting containing a fusible metal alloy and spring, which when exposed to 203˚- 212˚F temperatures releases a plug producing a metal-to-metal seat creating a bubble-tight seal. Fusible alloys are a reliable technology also commonly used in emergency fire sprinkler systems. Manufactured to German DIN 3586 Standards, the FireBag closes within 60 seconds of the set-off temperature and can withstand 1,697˚F for 60 minutes, allowing time for first responders to reach the dwelling and turn the gas supply off from the curb. Since the FireBag is a passive device and only triggers in a fire situation, it is maintenance free, and requires no regular inspections. No fire or heat detectors are required to automatically intercept the gas flow.
Where the FireBag is Used
The FireBag can be installed at various locations upstream of the gas meter and designed for use on indoor or outdoor, single meter and multi-meter installations, with pressure ratings ranging from inches water column to100 psig.
Single Residential & Commercial Metering Applications
FireBag Thermal Activated Shutoffs are available in multiple piping configurations and sizes to accommodate the varying piping requirements of a natural gas or propane system. A recommended FireBag piping orientation and design illustration is highlighted as follows, or simply contact your local Firebag distributor for additional information and specifications:
A — Upstream of the Regulator
Installed prior to the regulator, Male x Female FireBag configurations are available in ¾ – 2 NPT sizes.
B — Upstream of the Meter Bar
For installations after the regulator and prior to the meter bar, Female x Male FireBag configurations are available in ¾ – 1½ NPT sizes.
C — In-Line with the Meter Swivels & Nuts
Multi-Meter Gas Manifold Metering Applications
Natural gas and propane utilities now are able to add thermal shutoff protection to multi-meter installations at residential and commercial buildings, adding a level of fire safety previously unattainable. Various FireBag configurations are available for multi-meter gas manifolds, where each residence or business has its own gas meter. The FireBag configuration and sizes are available to utilities to meet the following installation options.
A — In-line with the Manifold
FireBag thermal shutoffs can be installed “prior-to” or “coupled-with” a multi-meter manifold to provide protection to multiple meters using just one device. Sizes include 1¼ , 1½ and 2 in Female x Female configurations.
B — In-line with the Manifold
Nipples to the Meter Individual Firebag installations place the thermal activated shutoff fittings between the manifold nipple and inlet to the meter bar. Sizes include 1 , 1¼ and 1½ NPT Female x Male configurations.
C — In-Line with the Meter
Swivels & Nuts A FireBag Meter Connection Kit can easily be installed on new or existing meter installations by utilizing a FireBag fitting in-line with the inlet swivel of the meter and accompanied by a BLANK companion fitting installed with the outlet swivel, keeping the meter balanced and level. Sizes include a ½ x ¾ reducing kit, ¾ , and 1 NPT Male x Female configurations.
