Stored-Energy Quick Cards
Match stored-energy hazards to the controls that render them safe.
Gravity load Which control belongs under a raised platen? Gravity energy needs a mechanical restraint or safe lowered state. Air pressure line A coworker says the air valve is closed, so the cylinder is safe. The air is off; let's open it. Your line Closed is not bled. We need to bleed the trapped air and verify zero pressure before the guard opens. Treating a closed supply valve as proof that downstream pressure is gone. It separates isolation of new energy from relief of stored energy. Heat What makes thermal energy safe for service? Cool to the procedure's service threshold…
