Assessment and completion
Complete the lessons in order and correctly answer every practice check. Practice is unlimited. Pass the final with at least 80% overall and every critical decision correct. Three final attempts are available per set, using alternating assessment forms and targeted lesson review after an unsuccessful attempt. An assessment attempt counts only when the server confirms it.
After passing, submit a 1–5 star rating to finish the course. Every rating is accepted equally; written feedback is optional. Your account retains the online knowledge completion, and you can download a knowledge record. This course does not issue an OSHA Outreach card or a professional or occupational certification.
Employer workplace component
This online knowledge component does not replace actual exposure assessment, implemented controls, employer task instruction, respirator medical evaluation and fit testing, or applicable medical surveillance. The employer must verify workplace understanding and complete the required programs before relying on protection.
The employer determines applicability and provides instruction in language and vocabulary the employee understands. Where the standard requires interaction with a knowledgeable or qualified trainer, arrange appropriate access through the employer. Academy support is asynchronous and has no guaranteed response time. Use the employer’s designated route for urgent safety decisions and required timely trainer access.
Online completion alone does not establish workplace compliance, operator qualification, competent-person status or permission to perform a hazardous task. Keep employer verification and any medical information in the employer’s appropriate records.
