When conducting indoor cable pulls during a shutdown or during new construction, do you follow the safety practices for temporary power and light? Violations of these practices can turn a cable pull into a tragedy, even if you do everything else right.
Also, if you're using a portable generator for power, try to locate it outdoors. If that isn't feasible, then don't rely on passive ventilation to magically dissipate the fumes.
Do you secure your cable spools so they won't come off their mountings? Using a cable pulling stand solves several potential safety problems while allowing the spools to rotate properly.
Whether you use a stand or go “old school” with a stick of electrical metallic tubing (EMT) or conduit stuck through the spool centers and supported on each end by empty spools, you need to make the rotation mechanically smooth. Avoid cable entry angles that might cause binding and think out the cable feed. Use the correct amount of lubricant at the correct intervals.
