Shipping rules for large refrigerators with flammable gas just got easier

The US Department of Transportation is making it easier to transport large refrigerating machines that use flammable gases. This means companies can now use a standard set of rules instead of applying for special permission every time they ship these machines.

For years, companies shipping large refrigeration units with flammable gases had to get a special permit for each shipment, which was a slow and expensive process. This change means they can now follow a single, clear set of rules, making it faster and cheaper to move these machines. This could accelerate the deployment of industrial and commercial refrigeration systems that use more environmentally friendly, but often flammable, refrigerants.
