Heat index is invisible. HeatAlert makes it visible.
A thermometer can't tell you when your facility becomes dangerous. HeatAlert Connect™ monitors temperature and humidity 24/7, calculates the real OSHA heat index every 10 seconds, and alerts you before workers start collapsing. Launching publicly in 2027 — join the waitlist now.
A thermometer reads 88°F — but that's not the whole story.
Heat index requires two measurements, calculated against each other. Same thermometer reading, wildly different danger levels. This is why handheld checks and building thermostats fail.
Workers feel warm but manageable. Fatigue with prolonged exposure. Breaks and hydration required per OSHA.
Heat exhaustion likely. Heat stroke possible with continued exposure. OSHA high-heat work rules kick in. Immediate intervention required.
Workers don't feel it coming — especially new ones.
Heat illness builds silently. By the time a worker feels "too hot," their core body temperature is already elevated. OSHA's own data shows how the risk lands overwhelmingly on people who haven't built tolerance yet.

Dashboard access included with every HeatAlert Connect™ unit at launch. Standard subscription tiers will be announced alongside the public product in 2027.
Any facility where heat kills productivity — or people.
Heat index is a universal metric. If your operation has workers in spaces that aren't fully climate-controlled, HeatAlert applies.
Distribution & Warehousing
Dock doors, sorting floors, storage zones. Indoor heat with humidity spikes during summer loading surges.
Manufacturing & Industrial
Assembly lines, foundries, processing facilities. Radiant heat from equipment compounds the thermometer reading.
Agriculture & Farming
Field crews, packing sheds, livestock operations. Outdoor exposure with minimal shade and long shifts.
Construction
Active jobsites, roadwork, roofing. Humidity and direct sun combine to push heat index 15°F above the thermometer.
Utilities & Energy
Power plants, substations, pump stations. Isolated workers in enclosed spaces where ventilation is limited.
Stadiums & Athletic Venues
Training facilities, outdoor stadiums, arenas. Duty of care for athletes, ground crews, and event staff.

The same family-owned manufacturer Amazon has trusted since 2012.
HeatAlert is built by IceAlert, Inc. — the Oregon-based company that's been making temperature-sensitive safety signs since 1998. Thousands of organizations trust our bimetallic IceAlert signs to protect people from ice. HeatAlert is the electronic counterpart, designed to do for heat what IceAlert has done for ice for 27 years.
We're a small family business. You'll talk to Jon, the owner, directly. No call centers, no account executives, no quarterly targets — just a product built by people who have to answer for it personally.
