Warehouse temperature monitoring that goes where your forklifts go

OSHA recommends warehouse temperatures of 68-76°F and 20-60% relative humidity. While there are no specific federal regulations, the General Duty Clause requires employers to maintain a workplace free from recognized hazards. OSHA's proposed Heat Illness Prevention Rule sets an 80°F action trigger. Many states have additional requirements. Continuous monitoring systems provide the documentation needed for compliance.

BLE (Bluetooth Low Energy) temperature sensors are placed throughout the facility in zones that need monitoring. As forklifts equipped with OneTrack sensors drive their normal routes, they automatically collect temperature, humidity, and wet bulb data from every beacon they pass. This provides continuous, facility-wide coverage without fixed infrastructure, WiFi gateways, or wiring.

Wet bulb temperature combines air temperature and humidity to measure heat stress risk for workers. A dry thermometer might read 85°F, but high humidity makes it feel much worse and inhibits the body's ability to cool through sweating. OSHA uses wet bulb globe temperature (WBGT) as the standard for heat stress assessment. Monitoring wet bulb temperature helps prevent heat-related illness and ensures compliance with workplace safety requirements.

When warm, humid air meets cold concrete floors (common in facilities near cold storage areas), condensation forms, creating invisible slip hazards. OneTrack sensors monitor temperature and humidity differentials to predict condensation before it occurs, triggering alerts so teams can take preventive action. This is especially critical in facilities with cold chain operations adjacent to ambient zones.

Fixed monitoring systems require WiFi gateways, power wiring, and careful placement, and still leave dead zones. OneTrack uses battery-powered BLE beacons collected by forklifts driving their normal routes. This means complete facility coverage, no infrastructure project, and deployment in hours instead of weeks. You also get more data points because forklifts travel every aisle, not just where you placed a fixed sensor.

Cold chain compliance typically requires continuous temperature logging with documented proof for audits. Requirements vary by industry: FDA mandates temperature control for pharmaceuticals and food (FSMA), while USDA has specific requirements for perishables. OneTrack provides automated documentation and reporting that satisfies audit requirements without manual logbooks or spot-checks.
