Simple and effective CO single gas detectors are ready-made for EMS, EMT, Police and Fire departments. Responding to reports of flu-like illness or unconscious citizens may involve CO poisoning, which also poses a risk to the first responders.

Cold weather or power outages seem to bring out creative methods of providing heat and light. From propane or kerosene heaters to clogged chimneys and vents, be prepared to detect this invisible, odorless gas. The size of a key fob, these carbon monoxide detectors can easily attach to the outside of your jump bag or can be clipped on your turnout gear to give you advance warning of this threat.

Maintenance free, just bump test monthly. Aerosol test gas makes this quick and easy. Standard alarm setting is 35ppm, though we can customize this to your department standards (e.g. 25ppm).
