Safety software for HVAC

Safety software built for HVAC crews.

A rooftop unit, a live circuit, a refrigerant line and a tight mechanical room, named on the FLHA with the control for each and signed on site before the service call starts. Daily checks, incidents and trade tickets, all from the phone in the technician’s pocket.

No signup to see it. See Muster Safety

Isolate it, ventilate it, then sign.

The lead names what the service call actually puts in front of the techs, the live circuit, the refrigerant, the roof edge, the mechanical room, and the control for each on the FLHA, and the crew signs on one phone before the panel comes off.

The record

The tickets, the checks, and the proof.

A gas or refrigerant ticket that lapses stops a job. Muster tracks certifications with expiry, keeps the daily checks and incident reports, and exports the record a client or a regulator asks for.

Common questions about HVAC safety software

Does it cover electrical, refrigerant and confined-space hazards?+
Yes. The live circuit, the refrigerant line and a tight mechanical room are named as hazards on the FLHA for the call, each with the control the crew signs off on, lockout, recovery, ventilation, before the work starts.
Can I track gas and refrigerant tickets?+
Yes. Certifications are tracked with expiry dates, so a ticket about to lapse is visible before the tech shows up to a job they are no longer certified for.
Can a technician report a burn or a release with no signal?+
Yes. A report started in a dead zone is saved on the device and sent the moment the phone has signal again, with a photo and a severity, so nothing is lost.
Does the whole crew sign the FLHA before the service call?+
Yes. The lead opens the FLHA on one phone and passes it around, so the whole crew signs before the panel comes off, with no app to install.
