Confined Space Entry Monitoring AI Across Tanks, Vessels, Vaults, and Pits

Deploy Anywhere, Run Everywhere

Run confined space entry monitoring on portable mast and trailer cameras, fixed plant cameras, the edge, on-prem, in your VPC, or via API, wherever your tanks, vaults, digesters, and turnarounds need it.

One Platform, Full Adoption

Tools every safety organization can adopt, from EHS leads and permit writers to entry supervisors, turnaround planners, and contractor safety managers, no separate ML team required to ship and own detection models.

Secure, Compliant, and Audit-Ready

Data stays safe with SOC 2 Type II compliance, encrypted data, and an uptime SLA, with documentation that supports OSHA permit-required confined space rules (29 CFR 1910.146 and 1926 Subpart AA), NFPA 350, and ISO 45001 programs.

Talk to a vision AI engineer who's shipped confined space entry monitoring on live sites.

A single attendant who steps away from the opening, an entrant who never signed out, or a retrieval line left unhooked can mean a rescue that starts minutes late, an OSHA citation, or the second casualty that follows when a coworker climbs in after the first. Bring us your toughest confined space entry monitoring problem and we'll map a working solution.
  • Solution architecture for OSHA 29 CFR 1910.146, OSHA 1926 Subpart AA construction entries, NFPA 350, and ISO 45001 programs
  • Live demo on your own entry footage, manway layouts, or turnaround camera positions
  • Deployment options: portable mast and trailer cameras, fixed plant cameras, edge, on-prem, air-gapped, or VPC, with integration into permit-to-work systems and site alerting
  • ROI modeling against rescue response time, permit audit hours, contractor compliance, and citation exposure
  • We will connect you with an AI subject matter expert on our team based on your answers.

    Know Who Is Still Inside the Space, on Every Permit, with Vision AI

    Add a real-time monitoring layer to every permit-required entry with vision AI for confined space entry monitoring. Built for the operations where one unattended manway, uncounted entrant, or unrigged retrieval line can mean a rescue that starts minutes late, an OSHA citation, or the second casualty that follows the first. Whether you're running refinery turnarounds, water and wastewater plants, grain and mining operations, or utility vaults, Roboflow extends your entry supervisor's sight to every space on every permit, on the cameras your site already runs.

    Entrant, Attendant, and Headcount Monitoring:

    • Detect each entrant crossing the manway or opening, and reconcile entries against exits so the count inside is always current
    • Verify the attendant holds the post for the duration of the entry, and alert the moment the opening goes unwatched
    • Flag entrants who stop moving where the camera can see, so response starts on the event rather than on a missed radio check

    Permit, Equipment, and Pre-Entry Verification:

    • Confirm the permit is posted, the space is barricaded, and warning signage is set before the first entrant goes in
    • Verify harnesses, tripods, davit arms, and retrieval lines are rigged and connected, not staged beside the opening
    • Check that ventilation blowers are running with ducting placed, and that the gas monitor is present at the entry point

    Unauthorized Entry, Contractors, and Records:

    • Detect entry into a posted space with no active permit, including after-hours entries and contractor crews
    • Apply different rules to different space classes, so a permit-required vessel and a non-permit vault each get monitored as written
    • Keep an event history with imagery that supports permit audits, contractor oversight, and OSHA program documentation

    Bring intelligence to every entry today. Stop an unwatched opening from becoming a rescue, a citation, or a multiple-fatality incident.

    More About Confined Space Entry Monitoring

    What is confined space entry monitoring with Vision AI?

    Confined space entry monitoring with vision AI uses computer vision models to watch the opening of a permit-required space and verify the controls the permit already calls for: who crossed into the space, how many are still inside, whether the attendant is at the post, and whether the retrieval line, blower, and gas monitor are in place. Models trained on your actual manways, vaults, and vessel openings apply your entry rules in real time and alert while there is still time to act. The result is a continuous record of every entry that supports OSHA permit-required confined space programs (29 CFR 1910.146), NFPA 350 practice, and ISO 45001 safety management systems.

    Can Vision AI monitor entries in dark tanks, vaults, and vessels?

    Confined space is one of the harder environments in industrial safety: low light inside the space, hard backlight at the opening, steam and dust during turnarounds, workers in bunker gear and SCBA that change silhouettes, and openings at odd angles on scaffold. Models trained on your site's actual entries learn what an entry looks like under your conditions, and pairing the opening camera with IR or a mounted light source keeps the crossing event reliable even when the interior is not visible. The honest tradeoff: a camera at the opening tracks who crosses it and what gear is rigged, and it can flag a motionless entrant only where it has line of sight. Deep inside a vessel, it complements atmospheric monitoring and attendant communication rather than replacing them.

    Does confined space entry monitoring support OSHA 1910.146 and ISO 45001 programs?

    Yes. Roboflow detection can run as documented monitoring that supports OSHA 29 CFR 1910.146 (permit-required confined spaces in general industry), OSHA 1926 Subpart AA (confined spaces in construction), NFPA 350 (guide for safe confined space entry and work), and ISO 45001 safety management systems, generating the entry records, attendant-coverage evidence, and event documentation that permit audits run on. Roboflow is the detection engine; your EHS team owns the permit program, the space classification, the entry rules, and the rescue procedure. Monitoring supplements a compliant entry program rather than substituting for the attendant, the atmospheric testing, or the rescue plan.

    Can it integrate with our permit-to-work system and site alerting?

    Yes. Entry events, headcount state, and attendant-coverage alerts push into permit-to-work and EHS platforms like Intelex, Cority, Enablon, and SAP EHS through REST, MQTT, and webhooks, so an open permit and a live camera state stay reconciled. Events can drive site alerting, radio dispatch, control room displays, and access control at the barricade, and can write to a historian or database for audit. Video can process at the edge so footage stays on site, which matters for air-gapped refineries and contractor-heavy turnarounds where uploading site video is not an option.
