## What is HeatStress?

Heat Stress Monitor helps workplaces assess heat stress conditions using temperature, humidity, to calculate Humidex, and WBGT estimates.

The app supports workplace heat stress awareness by allowing users to complete assessments, record environmental conditions, clothing and protective equipment adjustments, and radiant heat adjustments, document symptoms, and review recommended response actions.

Users can complete indoor or outdoor assessments, use local weather data for outdoor conditions, and save reports for future review. Reports can also be exported for record keeping and workplace health and safety documentation.

Key Features:
      - Complete workplace heat stress assessments
      - Record temperature, humidity, Humidex, and WBGT
      - Include clothing and protective equipment adjustments
      - Apply radiant heat and sun exposure adjustments
      - Document symptoms and response actions taken
      - View adjusted Humidex and effective WBGT results
      - Access OHCOW response recommendations
      - Save and review past assessments
      - Export assessment reports for records

Heat stress can occur in many workplaces, especially during hot weather, physical work, or when protective clothing is required. This app helps workers and workplace representatives better document conditions and respond appropriately.

Important: Heat Stress Monitor is an occupational heat stress assessment and documentation tool. It is intended to support workplace health and safety practices and is not a medical device. The app does not diagnose, treat, or prevent any medical condition and does not replace professional medical advice, professional judgment, or applicable workplace health and safety requirements. Workers should be trained to recognize the signs and symptoms of heat stress. If symptoms of heat illness are present, follow your workplace emergency procedures and seek appropriate medical attention immediately.
