Real-Time Exposure Monitoring

Know every exposure.
Protect every firefighter.

A detector mounted on the self-contained breathing apparatus (SCBA) measures what your crews are exposed to on the fireground: total volatile organic compounds (VOC) as a cumulative dose, alongside carbon monoxide, hydrogen sulfide, and combustible gas. Command sees a warning when someone passes a limit, and every reading lands in that firefighter’s career record.

The Problem

Exposure tracking is broken today

Every working fire puts your crews inside a cloud of combustion byproducts. What most departments use to track that exposure was never built for the job.

Manual paper logbooks

Exposure gets written by hand, when it gets written at all. A binder in a station office goes missing, takes water damage, or says nothing useful five years later.

Incidents, not people

Departments log the call, not the crew on it. Ask what one firefighter was exposed to over the past five years and nobody can answer.

Nothing flags on scene

While the fire is still going, command has no way to know who has taken on too much. Anything pieced together afterward comes too late to change how the call was run.

Screening starts blind

A physician seeing a firefighter has no record of what that member worked in, or how often. The conversation runs on memory.

Audit gaps

NFPA guidance and provincial and state occupational health regulators alike assume documented exposure records exist. When a department is asked to show it met its duty of care, a shelf of paper logs is a thin answer.

Retroactive cost

The bill arrives after a diagnosis: workers’ compensation claims, rising coverage, a crew down a member. None of it shows up in a budget until it is already owed.

Why It Matters

Cancer is the leading cause of the line-of-duty deaths the International Association of Fire Fighters honours.

What command and crews see

Two screens recorded from the Holyrood pilot: the chief dashboard during a call, and a firefighter’s own record after it.

Chief dashboard, recorded from the pilot

Every member on the roster, their running dose, and who is approaching a limit, on one screen the chief can act on during the call.

Every call a firefighter has worked, the dose from each one, and the career total underneath it.

The Platform

One platform. Field to record.

It starts with a detector on the SCBA and ends with a record that follows a firefighter through a whole career.

01

Measure

A multi-gas detector rides on the SCBA and reads total VOC, carbon monoxide, hydrogen sulfide, and combustible gas, with oxygen levels watched for atmosphere safety. VOC exposure accumulates as a dose in ppm·minutes (parts per million multiplied by minutes of exposure) for as long as the member is working.

02

Alert

Cross a threshold and incident command sees it while the crew is still on scene. The rules are fixed, so the same reading always gives the same warning.

03

Record

Each incident writes to a per-firefighter record that cannot be edited after the fact. The department can audit it. The member keeps their own copy.

The Product

Built to run your entire exposure program

Six capabilities on one platform, from the sensor on an SCBA to the compliance report on the chief’s desk.

Real-Time Dose Monitoring

Total VOC exposure measured in the field as a cumulative dose in ppm·minutes, updating while the call runs.

Why RespAI

A peak reading tells you almost nothing

A handheld detector reports the highest number it happened to see, not how long your crew stood in it. RespAI measures how much and for how long, so command reads the dose a firefighter has taken on so far, updated as the call unfolds. The alert rules are fixed and auditable, so a chief can explain any warning long after the incident closes. Firefighters helped design it, and the hardware mounts on the SCBA your crews already carry. Today the system measures total VOC. An e-nose in development is aimed at identifying the carcinogens themselves. That is the harder problem, and the one we are building toward.

On the Fireground

The first pilot is live

Holyrood Fire Department

Real exposure data, from real calls

Holyrood Fire Department is running RespAI on live calls. Detectors ride on the SCBA, dose data reaches the chief dashboard during the incident, and each member’s exposure record grows with every response.

This is not a prototype or a demo rig. The hardware goes out the door on the apparatus.
