Hazards Associated with Electrical Panel Installation!!


Recently, an electrician was installing the interior components of an electrical panel when he was cut by a mounting bracket that the outside door secures to. This particular task is performed on a frequent basis during new construction but injuries rarely occur during this task. The employee secured the nearby electrical wires out of his way and attempted to set the interior panel on the manufacturer’s bolts. When doing so, he held the top of the panel with his forearm while trying to align the holes in the panel to the bolts, when the panel shifted causing the mounting bracket located on the panel to strike the employees forearm against the outer door hanger brackets. In many cases one employee can perform this task safely even though the interior electrical components weigh approximately 25lbs. After the interior components are aligned with the bolts, wing nuts are installed to secure the interior panel. Then the electrical wires are landed before the outer shell and door is installed. These mounting brackets are pre-installed by the manufacturer but pose a serious cut hazard when the employee’s arms are exposed.

Factors to consider at your site and/or project include, but not limited to the following:

1.      Employees need to recognize the hazards associated with their tasks when working around sharp objects or edges.
2.      Specific gloves should be worn when working around these sharp objects and the employee and his/her supervision should determine if additonal personal protective equipment is needed to protect the arms such as a cut resistant sleeve.
3.      Personal protective equipment should be the last line of defense when mitigating a hazard. Contractor supervision needs to evaluate the method of installation and determine if the hazard can be engineered out. For example, contacting the manufacturer to see if the mounting brackets corners can be rounded to prevent another puncture or laceration from occurring.
Consider this example as you complete today’s work activities.
