3M™ Scott™ ATS Distress Signal Unit

The 3M Scott Personal Alert Safety System (PASS) and Heat Control Device is an advanced emergency alert system engineered to maximize the life safety of personnel operating in immediately dangerous environments. Offered by IST Safety Ltd (IST İşçi Sağlığı Teçhizatı), this professional device creates a vital safety layer, particularly for firefighters, search-and-rescue teams, and industrial maintenance crews.

Utilizing high-precision sensors, the device continuously monitors the user's movements. If the operative remains completely motionless for a predetermined period (typically 20-30 seconds), a pre-alarm is triggered; if immobility persists, it activates a high-decibel (95+ dB) audible and brilliant visual (LED) primary alarm to enable rescue teams to rapidly pinpoint the casualty's location. Additionally, the integrated thermal sensor tracks ambient temperatures to warn personnel against intolerable thermal exposure. Featuring a compact, lightweight, and impact-resistant housing, it easily integrates onto any breathing apparatus (SCBA) harness or protective clothing.

Usage Areas

• Firefighting & Structural Rescue: Ensuring firefighter safety in low-to-zero visibility environments involving heavy smoke and severe thermal hazards.
• Search & Rescue (SAR): Tracking and securing personnel during collapse, rubble, or confined space rescue missions.
• Confined & Restricted Spaces: Monitoring for potential fainting, toxic gas incapacitation, or oxygen depletion in storage tanks, manholes, tunnels, and vaults.
• Refineries & Chemical Utilities: Real-time safety tracking and distress signaling for lone workers or maintenance technicians in hazardous areas.
