The working space must allow cabinet doors to be opened to 90 degrees.

• A. True
• B. False
• C. Not specified
• D. Only for certain cabinets

Answer: (A)

Having enough working space so cabinet doors can swing open to 90 degrees ensures technicians can access the equipment for maintenance, inspection, and component replacement. When the door can open to a full 90 degrees, you can see inside the cabinet, reach wiring and modules, and connect or remove components without the door blocking access or risking cables being stressed. This full access is essential for safe, efficient servicing and reduces the chance of damage or injury from cramped work conditions. If the space didn’t allow that door swing, servicing would be cramped or impractical, which is why the requirement is that the working space must permit a 90-degree door opening. This isn’t limited to certain cabinets; it’s a general expectation to ensure proper accessibility across the setup.
