A Final Note
As a reminder, our OSHA 8-Hour HAZWOPER and Safe Ammonia Handling Refresher Training course is an online training that meets OSHA requirements for general site workers engaged in hazardous waste activities. However, it is ultimately the employer’s responsibility to ensure workers are sufficiently trained for job duties involving hazardous substances. To this end, employers may need to provide additional site-specific training depending on employees’ job type and experience.

All our courses are designed to take a specific amount of time. However, some students may get through this online training course much faster than others. This OSHA 8-Hour HAZWOPER and Safe Ammonia Handling Refresher Training course will take around 8 hours to complete.

Yes, participants must have previously completed either the OSHA 24-hour or 40-hour HAZWOPER training before enrolling in this refresher course. OSHA mandates annual refresher training to ensure that workers stay updated on safety procedures related to hazardous materials, including ammonia. Additional refresher training may be required if:
- Employees take on new tasks involving hazardous substances.
- OSHA regulations or workplace safety protocols are updated.
- An employee shows gaps in safety knowledge or improper work practices.
According to OSHA, “If the date for refresher training has lapsed, the need to repeat the initial training must be determined based on the employee’s familiarity with safety and health procedures used on site. The employee should take the next available refresher training course. There should be a record in the employee’s file indicating why the training has been delayed and when the training will be completed.”
According to OSHA, “Refresher training may be given in segments so long as the required 8 hours have been completed by the employee’s anniversary date.”
Certificate of Completion: Immediately after passing the final exam, you can download, save, or print your certificate in PDF format.
Validity: The 8-hour HAZWOPER refresher course certificate is valid for 12 months.
