Instructors were available for Questions

I Found the class more enjoyable than the Initial taken ten years ago. Rick and Max kept it interesting and plenty of time was given to cover what may have been lost during translation. Instructors also made themselves available at any time to assist with questions and concerns. Well spent three days with a great knowledge base. Thank you very much.

Very thorough in the Information

Rick and Max gave a great class. Very thorough in the information and emphasis on the importance of various regulations. They covered OSHA, NFPA, Navy, etc. regulations and provided great material to reference. I think the class could have been better in person but considering a pandemic, these guys did a great job getting the information across to the class.
