9. A person who fills or refills a container or a refrigeration or air conditioning unit with a halocarbon or charges or recharges a fire extinguisher is required, subject to section 12, to first leak test the equipment.
In addition, where the refilling or recharging is done with a halocarbon other than the original halocarbon, the person is required to see that a label indicating the type of halocarbon used for the operation is affixed to the container or the unit.
No person may use sulfur hexafluoride (SF6) to conduct the leak test referred to in the first paragraph.
