: Outlines requirements for climbing safety, platforms, lighting, and lightning protection, often aligned with OSHA standards .
Stacks must handle dead loads, thermal expansion stresses, and live wind or earthquake loads simultaneously. The document lists strict guidelines for computing:
The is the premier technical publication governing the mechanical design, structural analysis, fabrication, and maintenance of steel stacks. Published by the American Society of Mechanical Engineers (ASME) , this comprehensive standard ensures that single- and multiple-walled steel stacks operate safely under varying environmental and operational loads.

The ASME STS-1-2021, titled is a comprehensive standard that provides requirements for the design, fabrication, erection, inspection, and maintenance of steel stacks. "Steel stacks" are defined as those structures where the primary supporting shell is constructed of steel. These stacks are commonly used to release combustion gases or other non-flammable exhaust into the atmosphere at high altitudes to prevent damage to equipment and comply with environmental and safety regulations.

The most significant change in the 2021 edition is a fundamental shift in the wind load design philosophy.
The Draft Beneath the Stack
Occupational safety bodies (like OSHA in the United States) and local jurisdictions routinely audit industrial plants. Non-compliance with recognized engineering standards can result in hefty fines or forced shutdowns.

The primary intent of the code is to manage the venting of nonflammable process gases—such as combustion exhaust—at low internal pressures. For flare stacks or volatile venting systems containing flammable mixtures, the standard mandates modifications and compliance with companion codes such as ASME B31.3 (Process Piping) and ASME BPVC Section VIII.
