06Questions
Is heat illness training required?
It depends on your state and job. Federal OSHA has no final heat standard (its 2024 proposal was still not final in October 2026), but its General Duty Clause requires employers to protect workers from recognized hazards, and heat is one. Some states, such as California, Washington, Oregon and Maryland, have their own heat rules, with training duties. There is no OSHA license or card for heat training.
Will my employer accept this certificate?
It is a certificate of completion: it shows you finished this general awareness course and passed its test. It is not a regulated or accredited qualification, and it is not issued, approved or endorsed by OSHA or any government agency. Your employer decides whether it meets their needs, and they must still train you on the heat hazards, the heat plan and the emergency steps at your own workplace.
Does this course replace the training or the heat plan my employer must give?
No. It teaches the general ideas: why heat is dangerous, water, rest and shade, acclimatization, the signs of heat illness and first response. Your employer must still assess the heat hazards at your site, give site-specific training and a written plan where the law or policy requires one, and set up emergency procedures.
Does the course give medical or first aid training?
No. It teaches how to recognize the signs of heat illness and what to do first, such as calling 911 and cooling a person. It does not make you a first aider or a medical professional, and it is not medical advice. Ask a doctor about your own health.
How long does it take?
Most people finish the lessons and the test in about an hour. You can stop and come back at any time on the same device.
What if I fail the test?
Nothing is charged. You see which lessons to read again and can retake the test as often as you need.
When do I pay, and how much?
Only after you pass: $15 for the certificate. The course and the test are free.
How does my employer check the certificate?
Every certificate has a number and a QR code. Scanning it, or entering the number on our check page, shows your name, the course and the date you passed.
How often do I need to renew?
Federal law sets no fixed refresher interval for heat training, and state rules differ (Maryland, for example, asks for yearly heat stress training). Many employers ask for a refresher before each hot season, so the certificate shows a renewal date 12 months after you pass.
Does this cover state rules?
The course explains the federal position and names several state rules, but heat rules change and differ from state to state. Ask your employer or your state OSHA or labor department which rules apply to you.
The certificate confirms that you completed this course and passed its test. It is not a regulated or accredited qualification; your employer decides whether this training meets their requirements.
