PHMSA issues urgent warning for cylinders sold online
In a critical safety advisory, the Pipeline and Hazardous Materials Safety Administration (PHMSA) has sounded the alarm on unauthorized gas cylinders being sold online. These cylinders, which lack proper certification and are not manufactured to DOT specifications or UN standards, pose severe risks, including potential explosions and toxic gas releases, threatening both public safety and the environment.
PHMSA identified several instances where empty cylinders, lacking proper certification markings, are being sold to consumers and HVAC technicians. These cylinders, primarily manufactured by non-U.S. companies, are not designed to safely contain and transport hazardous materials. The use of such cylinders can lead to severe consequences, including property damage, physical injury, or even death.

Regulatory compliance
The advisory emphasizes the importance of ensuring that cylinders comply with the Hazardous Materials Regulations (HMR). Cylinders must be marked according to DOT specifications or UN standards before being transported. Unauthorized cylinders, once filled, violate these regulations and can result in civil penalties or criminal prosecution.
Safety risks
Using non-compliant cylinders can lead to the release of high-pressure hazardous gases, posing serious health and safety risks such as fires, explosions, and inhalation injuries. PHMSA urges consumers and HVAC technicians to verify the compliance of their cylinders to prevent such incidents.
Identifying authorized cylinders
Authorized cylinders are marked with "DOT" or similar international standards like UN ISO 9809. Consumers should check for these markings and review item specifications or seller feedback when purchasing cylinders online. Follow these safety tips to ensure your cylinders meet HMR standards:
Verify cylinder markings:
- Look for certification markings indicating the cylinder meets DOT or UN specifications.
Purchase from reputable sources:
- Buy cylinders from trusted retailers and manufacturers.
- Avoid purchasing cylinders from unknown or unverified online sellers.
Check for compliance:
- Review item specifications and seller feedback before purchasing cylinders online.
- Ensure the cylinder's description includes compliance with DOT or UN standards.
Proper handling and storage:
- Store cylinders in a cool, dry place away from direct sunlight and heat sources.
- Handle cylinders with care to avoid damage that could compromise their integrity.
Regular inspections:
- Periodically inspect cylinders for signs of wear, damage, or corrosion.
- Ensure cylinders are requalified and tested by a DOT-approved inspector.
Safe disposal:
- If you have a non-compliant cylinder, return it to the point of sale if it is empty.
- For filled unauthorized cylinders, seek assistance from a licensed technician for safe disposal.
PHMSA will continue to monitor and investigate the sale and use of non-compliant cylinders and provide updated guidance as necessary. However, it’s up to consumers to ensure they are using the appropriate cylinders by using the safety tips listed above.
Key to remember: PHMSA identified several cylinders being sold online that are not compliant with HMR standards, which can be deadly if used. Ensure your cylinders are compliant with the HMR or UN standards by checking to see if they are properly marked.
