Prevention – Heat Hazard Recognition
Use this app for knowing what to do in the heat and humidity=heat index. Click here for app.
There are many factors that have a role in creating an occupational heat stress risk to workers. These factors include:
Environmental conditions (such as air temperature, humidity, sunlight, and air speed), especially on sequential days.
Presence of heat sources (e.g., hot tar ovens or furnaces) in the work area.
Level of physical activity, i.e., the workload leading to body heat production.
Use of clothing or protective gear that can reduce the body’s ability to lose excess heat.
Individual/personal risk factors.
Workload considerations are described at length in the OSHA Technical Manual. Common values given for categories of work are included in the table on Workload.
