Frequently Asked Questions

Who must take this training?

All employees required by OSHA (or their employer) to wear respirators to protect them from occupational diseases caused by breathing air contaminated with harmful dusts, fogs, fumes, mists, gases, smokes, sprays, or vapors.

How often is retraining or recertification required?

The length of time for which the training is valid is determined by OSHA 29 CFR § 1910.134:

(k) (vii) The general requirements of this section.
(3) The employer shall provide the training prior to requiring the employee to use a respirator in the workplace.
(4) An employer who is able to demonstrate that a new employee has received training within the last 12 months that addresses the elements specified in paragraph (k)(1)(i) through (vii) is not required to repeat such training provided that, as required by paragraph (k)(1), the employee can demonstrate knowledge of those element(s). Previous training not repeated initially by the employer must be provided no later than 12 months from the date of the previous training.
(5) Retraining shall be administered annually, and when the following situations occur:
(i) Changes in the workplace or the type of respirator render previous training obsolete;
(ii) Inadequacies in the employee’s knowledge or use of the respirator indicate that the employee has not retained the requisite understanding or skill; or
(iii) Any other situation arises in which retraining appears necessary to ensure safe respirator use.

What are the governing regulations?

This online course satisfies the training requirements of OSHA 29 CFR § 1910.134 Respiratory Protection Standard.

Navigation Strategies

Beginners: Complete the course in order from beginning to end. Once any topic is completed, you will have full access to it at any time for one year after registration, to use as a resource.

Intermediate/Advanced Users: Use the course as a flexible resource tool to find what you need, whenever you need it. Try the assessment tests first, if you get 80%+ you can move to the next level, if you get less than 80% you should complete the lecture. This gives you a pre and post-assessment score, which can be used to track your skills improvements.
