What does 49 CFR 180.213 (Requalification markings) require?

Short answer

49 CFR 180.213 requires that each cylinder or UN pressure receptacle requalified in accordance with the subpart must be marked as specified in the section, with required specification markings not altered or removed. The markings must include the requalification date and the RIN set in a square pattern.

The rule says

"Each cylinder or UN pressure receptacle requalified in accordance with this subpart with acceptable results must be marked as specified in this section." (49 CFR 180.213(a))

"Requalification markings may be placed on any portion of the upper end of the cylinder excluding the sidewall, as provided in this section." (49 CFR 180.213(b)(1))

"Each cylinder successfully passing requalification must be marked with the RIN set in a square pattern, between the month and year of the requalification date." (49 CFR 180.213(d))

In plain English

The regulation requires that cylinders be marked with specific information after requalification, including the requalification date and the RIN of the person performing the requalification. The markings must be placed on the cylinder in a specific location and must be legible and durable. In practice, this means that inspectors will check for the presence and accuracy of these markings during inspections, and that any cylinder without proper markings may be considered non-compliant.

What to do

• Ensure that all requalified cylinders are marked with the required information, including the requalification date and RIN.
• Verify that the markings are placed in the correct location on the cylinder and are legible and durable.
• Maintain records of cylinder requalification and marking, as required by 49 CFR 180.215.
• Train personnel on the proper procedures for marking and recording cylinder requalification information.
