Exelon Powerlabs October 2016 - Rigging And Fixturing

Explanation
Rigging and fixturing equipment should be visually inspected prior to each use to ensure their safety and effectiveness. Regular inspections help identify any potential damage, wear, or defects that may compromise the equipment's functionality or pose a risk to workers. By conducting these inspections before every use, any issues can be promptly addressed, reducing the likelihood of accidents or equipment failure during operation. This proactive approach ensures that the rigging and fixturing equipment is in optimal condition and minimizes the potential for workplace incidents.

Explanation
Both a and b above are correct safety practices that can be utilized when performing work involving rigging and fixturing. Ensuring that personnel and other equipment are clear from the "Line of Fire" in the event of a failure is important to prevent any potential injuries or damages. Additionally, using safety barriers/shields to protect personnel and equipment in case of a failure adds an extra layer of protection. Running quickly, as mentioned in option c, is not a safety practice and does not contribute to the safe execution of rigging and fixturing work.

Explanation
Rigging and fixturing must be inspected for irregularities because cracks and deformation can compromise the load rating. Cracks weaken the structure and can lead to failure under load, while deformation can alter the shape and integrity of the rigging or fixture, also affecting its load-bearing capacity. Worn paint, on the other hand, does not directly compromise the load rating as it does not affect the structural integrity of the rigging or fixture. Therefore, the correct answer is "Both a and c above."

Explanation
When rigging and fixturing equipment is defective and damaged, it poses a safety risk to workers. Therefore, the correct course of action is to immediately tag and remove it from service. This ensures that the faulty equipment is not used and potentially causes accidents or injuries. Repairing it at a service shop or placing it back in storage without addressing the damage would only perpetuate the risk. Donating it to charity is also not a suitable option as it could put others at risk.

Explanation
If you are unsure if the given load capacity is the rated capacity, a safety factor of 4 is applied. This means that the actual load capacity is four times higher than the given load capacity. Applying a safety factor helps to ensure that the equipment or structure can handle unexpected variations or uncertainties in the load, providing an extra margin of safety.
