Fuel Tanks

ASME Container Location and Safety Requirements for Pratt Guys

In many projects, Pratt Guys encounters existing gas or propane tanks that need to be relocated or integrated into new outdoor living space designs. Ensuring compliance with ASME standards for these fuel containers is critical for maintaining safety. These standards dictate the required distances from structures, ignition sources, and property lines, minimizing fire hazards and liability while ensuring clients can safely enjoy their upgraded spaces.

Importance for Pratt Guys Projects:

When dealing with existing fuel tanks, whether they are part of an outdoor kitchen, fire pit, or heating system, Pratt Guys needs to determine the best way to either relocate the tanks or design around them without compromising safety. Relocating tanks to meet ASME standards may be necessary if the existing placement does not adhere to required clearances from structures or ignition sources. Proper planning will ensure compliance with safety codes while allowing creative design solutions that fit the client's vision.

Key Relocation and Design Guidelines:

Container Size and Required Distances:

Tanks under 125 gallons: These must maintain at least a 10-foot distance from any sources of ignition (e.g., central A/C units, outdoor fireplaces). If above-ground, they also need to be at least 5 feet from any structure. When working with these tanks, it’s important to check if the existing tank is placed too close to client homes or outdoor appliances and consider moving it to a safer location.

125 to 500 gallons: These tanks require a 10-foot minimum distance from structures or property lines. If the current placement violates this, relocation or additional safety measures will be required. For tanks larger than 500 gallons, the separation between tanks also becomes important, with a 25-foot clearance between multiple containers.

Integrating Underground or Mounded Tanks:

These types of tanks are often found in existing projects, especially in more aesthetically conscious designs. They still need to maintain a 10-foot distance from structures and property lines. When integrating them into new designs, it's critical to ensure access to the tanks for maintenance and refueling while keeping them safely placed according to code.

Appliance and Ignition Source Distances:

Outdoor appliances like stoves, grills, or fireplaces often have existing gas connections. Ensuring these connections meet the required safety distances is vital. For example, tanks feeding these appliances must be placed far enough away from windows, doors, crawlspaces, and other potential sources of ignition.

Site Planning for Relocation or Design Around Existing Tanks:

For projects where tanks need to be relocated, it’s essential to assess the existing placement, ensure compliance with ASME standards, and document the new location in relation to structures and property lines. When designing around existing tanks, Pratt Guys should incorporate these distances into the layout, ensuring that any potential hazards are accounted for while maintaining design integrity.

Additional Considerations:

Ventilation and Safety Requirements: Relocated tanks should still adhere to ventilation requirements, particularly around direct-vent appliances or HVAC intakes, ensuring they are at least 5 feet away.

Labeling and Signage: Once relocated, proper signage indicating the size and content of the tanks should be applied to avoid confusion during inspections or emergencies.
