Exposure to impalement is a serious consideration when employees are working above sharp objects like the pointed lightning rod. OSHA regulations
recognize the risk of impalement and require protection for employees where impalement hazards exist. This recognized hazard has prompted the use of numerous ineffective methods of protecting personnel from
roof mounted pointed lightning rods. Methods include the use of warning markers, acrylic tip covers, and in some cases the entire rod is covered with pvc conduit. The use of these types of protectors can
drastically reduce system performance while doing little to protect against impalement.
