Frequently Asked Questions

All classes begin at 8:00 am, except the Management Planner Refresher, which begins at 1:00 pm on scheduled dates. 


(2) When should I pay?  

Payment for class must be made by check, credit card, or cash on or before the day of class.  


(3) How long do I have after my EPA/AHERA certificate expires to take a refresher course?  

For all asbestos refresher courses, the student has one year from the date of expiration on the certificate from the training facility to be eligible for a refresher course. During that year grace period, the student is out of compliance and must renew the certification before working in the industry.
