Refrigerant Management Solutions (RMS): Next Generation Compliance for Next Generation Regulations
Refrigerant Management Solutions (RMS): Next Generation Compliance for Next Generation Regulations

Regulations | Many retailers rely on their service contractors and technicians to keep them in compliance with federal and state refrigerant regulations. Federal regulations have changed multiple times in the past 5 years, and there are new regulations coming out this year and next year. Oh, and new states are joining the mix every year. Have you kept up? If not, you’re not just creating liability for your customers, you’re also missing out on a business-building opportunity. Training provided by Keilly Witman.

Refrigerant Management Solutions (RMS): Not Just Another Presentation on Regulations

Regulations | Is the goal of your refrigerant compliance program to keep you in compliance? If so, you’re missing the point. Food retail end-users are chasing their tails trying to find compliance issues and fix them. What they should really be doing is preventing compliance issues in the first place. The EPA declared in August that enforcement of the Aim Act is one of their top priority areas. Are you ready? Are you sure? Really? Training provided by Keilly Witman.
