Propane is an extremely safe alternative fuel source with an excellent safety record, which is largely down to the strict regulations governing the industry, including propane tank certification and the requirements for periodic recertification.
However, regardless of the fuel being used, the importance of safety and compliance with regulations cannot be overestimated, and propane is no different. In this article we’ll cover everything you need to know about recertifying propane tank, including:
Depending on the purpose, propane can be stored in bottles also called cylinders or in tanks, also called bulk. There are various sizes for cylinders and tanks:
Propane cylinders are mainly used for outdoor activities and can be either refilled or exchanged when empty.
| Size | Description | Use |
| 20-pound | Compact and easy to transport. | Primarily for outdoor activities, e.g. portable grills, camping stoves, and small appliances. |
| 30-pound | Larger than 20-pound tanks but still relatively portable. | Primarily for outdoor activities, e.g. portable grills, camping stoves, and small appliances. |
| 40-pound | A bit larger than the 30-pound tanks and commonly used in residential settings. | Primarily for outdoor cooking, with small to medium-sized grills and appliances. |
Bulk propane tanks are, as the name suggests, larger than portable cylinders / bottles and are refilled by propane delivery trucks.
| Size | Description | Use |
| 250 Gallon | Typically installed outside homes. | Commonly used for residential heating, cooking, and hot water systems. |
| 500 Gallon | Larger and can be installed underground or above ground on a concrete pad. | Commonly used for heating larger homes, multiple appliances, and sometimes for small businesses. |

Propane tanks do not have a specific expiration date, but they are subject to periodic inspections and recertifications. The propane tank certification process ensures that the tank remains compliant with safety standards and, crucially, remains safe.
The timeframe for recertification depends on the specific type of propane tank and local regulations, but it is typically performed every five, seven, 10, or 12 years.
Propane tanks typically have a date stamp or code that indicates the manufacturing date, often a series of letters and numbers. It could be MM-YY (month-year) or a specific code, and it's usually located on the collar or foot ring of the tank.

Involves a combination of visual inspections, testing, and compliance checks to assess and confirm that a propane tank remains structurally sound and safe for use.
A broader term that encompasses the requalification process, this involves verifying the compliance with safety standards and confirming its safety for use over a specified period.
ASME (American Society of Mechanical Engineers) and DOT (Department of Transportation) are two different standards that apply to propane tanks and are dependent on their use.
ASME standards apply to propane tanks designed for stationary use, such as those used for residential heating. Periodic inspections and recertification are typically required.
DOT standards are designed for propane tanks designed for transport (e.g. propane delivery trucks) or recreational vehicles. Recertification at specific intervals is mandatory.
