Rhode Island General Laws Title 23. Health and Safety § 23-28.22-7. Attendant required

All self-service stations shall have at least one qualified attendant on duty while the station is open to the public. During all times that Class 1 liquids are actually being dispensed, the attendant's primary function shall be to supervise, observe, and control the dispensing of the liquids. It shall be the responsibility of the attendant to prevent the dispensing of Class 1 liquids into portable containers unless the container is constructed of metal or approved plastic or is approved by the authority having jurisdiction, has a tight closure with screwed or spring cover, and is fitted with a spout or so designed that the contents can be poured without spilling. It shall also be the responsibility of the attendant to control sources of ignition, and to immediately handle accidental spills and fire extinguishers, if needed. The attendant or supervisor on duty shall be capable of performing the functions and assuming the responsibilities covered in this section.
