What should you do first before removing any piping or equipment?

Before removing any piping or equipment, the first critical step is to ensure safety and system integrity. Chocking a spring is particularly essential in systems where springs or pneumatic components may potentially create hazards if they are suddenly released when the equipment is being disassembled. This action helps to prevent accidents that may occur from uncontrolled movement or tension that could result from removing components.

In scenarios involving piping or mechanical systems, if springs are present, they can exert significant force and, if not properly secured (chocked), can lead to injury or equipment damage. This proactive measure allows technicians to handle equipment safely.

While disconnecting power supplies and draining fluids are also important steps, they typically follow after stabilizing the equipment that may have hazardous stored energy, such as springs. Removing insulation is generally a preparatory task that may come later in the process when some of the safety measures have already been executed. Thus, securing any potential hazards, such as springs, is the priority before taking further action.
