Unsafe Conditions in Your Facility ― Part 1
Does your facility contain unsafe conditions, and do you know what to do about them?
Let's start with inadequate working space, a problem that is far more prevalent than many people realize.
The typical response when this issue is raised is to measure three feet and say it's good. But three feet depth from an energized panel is only one of several minimum clearances mandated by OSHA and the National Electrical Code (NEC) [1926.403 and 110.26] primarily for shock prevention. Height and width clearance are also mandated in the OSHA and NEC working space tables. But as with depth, they are only minimums.
Additional space may be needed to safely move equipment. In one plant, it was necessary to remove a 400-lb arbor from the top of a machine to replace a sensor. Clearance for the lifting equipment and the lifting process was provided; otherwise there would not have been a safe way to replace the sensor.
It's not about measuring to meet table requirements. It's about measuring to meet safe work requirements. That is no small distinction.
