06Questions
Is hazard communication training required?
Yes. OSHA's Hazard Communication Standard (29 CFR 1910.1200(h)) requires employers to give workers effective information and training on the hazardous chemicals in their work area, at initial assignment and when a new chemical hazard is introduced. The law requires the training itself. There is no OSHA license or card for it.
Will my employer accept this certificate?
It is a certificate of completion: it shows you finished this general 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 chemicals, procedures and protective equipment in your own work area.
Does this course replace the training my employer must give?
No. It teaches the general system: labels, pictograms, safety data sheets and your rights. Your employer must still give site-specific training on the hazardous chemicals you work with, the written hazard communication program, the chemical list and where the safety data sheets are kept.
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: $19 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?
The OSHA standard does not set a fixed refresher interval. It requires training when you are first assigned and when a new chemical hazard is introduced. Many employers ask for a yearly refresher, so the certificate shows a renewal date 12 months after you pass.
Does this cover state rules?
The course follows the federal OSHA standard. About half of the states run OSHA-approved state plans that may add requirements, and OSHA has phased dates for the 2024 update. Ask your employer 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.
