See the exposure as it happens — not three days later in a lab report.
Dust, gas, diesel particulate, noise and heat do their damage over a career, and a spot sample read days later protects no one in the moment. addanode delivers continuous, real-time occupational hygiene monitoring — alerts before a limit is breached, and a defensible, unbroken record for MHSA compliance and medical surveillance.
The exposures that matter, continuously.
Dust & DPM
Respirable dust (silica, coal) and diesel particulate matter — the drivers of occupational lung disease in confined workings.
Gases
Carbon monoxide, methane, oxides of nitrogen and oxygen deficiency, by commodity and method.
Noise & heat
Noise from drilling, crushing and ventilation, and heat-stress in deep, hot workings — both immediate and cumulative risks.
From documenting exposure to preventing it.
- Act before the limit is breached — live readings trigger ventilation, sprays or withdrawal before an exposure limit is exceeded, not next week.
- Catch the peaks — a short, severe spike does the damage; continuous data sees what spot samples miss between visits.
- Find the sources — time- and place-stamped data shows which activity or area drives exposure, so controls target the real cause.
- Verify your controls — measure before and after a ventilation or spray change and prove it reduced exposure.
- Build a defensible record — continuous data for MHSA compliance, Section 11 risk assessments and medical surveillance, on the addaNet platform alongside collision prevention and person location.
It supports your hygienist, it doesn't replace them. Continuous monitoring widens coverage and catches peaks between formal sampling campaigns; your occupational hygienist still sets the strategy and signs off compliance.
Always confirm current occupational exposure limits and obligations against the latest Mine Health and Safety Act, its regulations and your appointed occupational hygienist.
