Where a steam boiler hurts people
- The boiler holds pressure and heat for hours. Let it cool and vent it to 0 before opening anything.
- Close and lock the gas valve upstream of the burner train, and test for gas before you open the burner.
- Opening a steam line needs double block and bleed when other boilers share the header.
