Why Workers and Employers Choose Safety First Training
For Canadian employers, supervisors, and workers building a safe, respectful workplace.
Heat stress rarely strikes without warning — there are almost always early signs, if you know what to look for. This course guides you through the Canadian OHS framework, your duties under the law, the physiology of heat and its key risk factors, prevention and control strategies, and the correct procedures for recognizing, responding to, and reporting heat-related illness. Through practical examples and clear explanations, you'll gain the knowledge and confidence to comply with all legislative requirements and help foster a safer workplace for everyone.
Prevention Is a Shared Responsibility
Employers are required to assess the risks, put policies and controls in place — such as work-rest schedules, hydration strategies, and Humidex or WBGT monitoring — and respond appropriately to heat-related incidents. Workers, in turn, are expected to follow those policies, stay alert to the warning signs in themselves and their coworkers, report symptoms and concerns early, and cooperate in keeping the workplace safe.
Key definitions and concepts, and the different forms they take in law and in practice.
Understand how the human body regulates temperature. Knowing how our bodies respond to heat and what can go wrong forms the foundation for all effective prevention strategies.
Understanding the warning signs and acting quickly can prevent serious injuries, long-term health effects, and even fatalities. Early recognition and response are critical to protecting both individual workers and the entire team.
Accurately assessing heat risk is essential for protecting workers in Canadian workplaces. Objective measurement tools like the Humidex and Wet Bulb Globe Temperature (WBGT) allow employers and supervisors to make informed decisions, prevent heat-related illnesses, and comply with legal requirements.
Applying the hierarchy of controls is the most effective way to prevent heat stress injuries and illnesses. By layering proactive measures, starting with the strongest controls and working down, you can protect yourself and your team, meet Canadian OHS standards, and create a safer, more productive environment.
In this lesson, you’ll learn the essential skills and steps needed to protect yourself and your coworkers when it matters most.
The course is fully self-paced, so you can start, stop, and pick up again on your own schedule. Every lesson is voice-narrated with interactive checkpoints that confirm you've absorbed each section before moving on. As soon as you pass the final exam, you can immediately generate your certificate.
