What is the most important reason to insulate a steam riser in an apartment?

• A. Tenants don't get burned
• B. Reduce energy costs
• C. Improve steam quality
• D. Prevent corrosion

Answer: (A)

The main idea here is safety. Steam risers carry very hot steam, and people—especially in apartments—can accidentally touch exposed piping. Uninsulated metal surfaces on a riser can be hot enough to cause serious burns. Insulating the line lowers the surface temperature, creating a protective barrier against scalds for tenants and maintenance staff. Energy savings, steam quality, and corrosion control can be improved as side effects of insulation, but they are not the primary reason in this context. Safety-driven protection against burns takes priority because the risk to people is immediate and severe.
