The summer heat can be brutal, especially in workplaces where employees are exposed to extremely high temperatures and humidity. To ensure workers' health and safety, it's crucial to provide them with the right equipment and technology to stay cool and comfortable. 

In this blog, we'll explore the four types of cooling personal protective equipment (PPE) technology and the best products available in the market. We'll also discuss the importance of personal and area monitoring in managing heat stress in the workplace, particularly in Canada, where various industries are exposed to potentially hazardous thermal conditions.

Here are the top personal and area monitoring tools to select from:

Personal Monitoring Device:

SlateSafety Band V2:
