Dear Mr. Gayon:
This letter is in response to your October 10, 2019, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to leakage tests performed on DOT 3A cylinders. Specifically, you ask whether it is permissible to use cameras to detect and closely examine for indications of leakage as required by § 178.36(m)(1).
The answer is yes. Section 178.36(m) specifies that all spun cylinders and plugged cylinders must be tested for leakage by gas or air pressure. A video camera may be used to perform the required examination provided that all areas can be viewed in a manner equivalent to that which would be expected if viewed directly by a person.
I hope this information is helpful. Please contact us if we can be of further assistance.
Sincerely,
Dirk Der Kinderen
Chief, Standards Development Branch
Standards and Rulemaking Division
178.36(m), 178.36(m)(1)
