1. Restricted sale only to licensed technicians

2. No sales restriction on HFC-134a in containers less than two pounds

3. Restricted for consumer purchase

4. Sales only allowed through authorized dealers

The correct answer is: No sales restriction on HFC-134a in containers less than two pounds

The correct choice indicates that there are no sales restrictions on HFC-134a in containers less than two pounds. This means individuals or businesses can freely purchase these smaller containers without needing a specific license or certification. In the context of regulations, substances like HFC-134a, used in cooling applications, are often subject to restrictions due to environmental concerns. However, containers of this particular size are treated differently, allowing for greater accessibility to consumers and technicians who may need these for purposes such as vehicle air conditioning repairs or other refrigerant applications. In contrast, larger containers of HFC-134a often have stricter regulations due to the potential for more significant environmental impact. This is often because larger quantities could lead to more considerable emissions in the event of a leak or improper handling. Consequently, certain requirements, such as technician licensing or sales through authorized channels, are implemented to ensure safety and compliance with environmental standards.
