3-4 Warning signs, ropes and/or barricades to ensure area affected by load testing is secured
4. GENERAL PRECAUTIONS
4-1 Only those personnel actively engaged in performing or witnessing this test shall be permitted in the testing area. All specified safety regulations shall be strictly observed.
4-2 To prevent injury or death, ensure that proper test equipment is used during testing.
4-3 The warning signs shall be posted prior to starting the test.
4-4 Safeguarding of personnel and equipment shall be adhered to at all times.
4-5 Comply with Navy Safety and Occupational Health (SOH) manual, OPNAVINST 5100.23 as well as any additional guidance from other applicable policy.
4-6 Comply with ship's regulations when working at or over the side. Wear non -inflatable life preserver, safety harness, and safety lanyard secured to a suitable structure.
4-7 For hinged safety nets, rig temporary lifelines and lashing, as required, prior to lowering safety net frames to the down (horizontal) position.
4-8 Wire rope pendant thimble(s) found to have cracks or found to have portions of material broken off are a potential FOD hazard.
4-9 Quick release hook with faulty or missing pull lever retaining springs can result in unexpected disengagement of the hook, releasing the pendant assembly. This could lead to personnel injury if personnel are in safety net during disengagement. Quick release hooks with faulty or missing retaining springs can be secured by seizing pull lever to hook body using CRES seizing wire until new replacement hooks are installed.
4-10 Ensure that safety net frame is secured in the up (vertical) position. Disengage one quick release hook at a time from pendant assemblies on each frame. One pendant assembly shall always remain connected between safety net frame and ship's structure.
4-11 Latch mechanism is designed to secure safety net frame in the up (vertical) position. In this position, frame is acting as a restraint system (liferail) to prevent personnel from falling overboard or to a deck below. An improper working latch mechanism or bent/damaged frame holdback staple may lead to personnel injury should frame drop when contacted or leaned on by personnel.

4. GENERAL PRECAUTIONS
4-1 Only those personnel actively engaged in performing or witnessing this test shall be permitted in the testing area. All specified safety regulations shall be strictly observed.
4-2 To prevent injury or death, ensure that proper test equipment is used during testing.
4-3 The warning signs shall be posted prior to starting the test.
4-4 Safeguarding of personnel and equipment shall be adhered to at all times.
4-5 Comply with Navy Safety and Occupational Health (SOH) manual, OPNAVINST 5100.23 as well as any additional guidance from other applicable policy.
4-6 Comply with ship's regulations when working at or over the side. Wear non -inflatable life preserver, safety harness, and safety lanyard secured to a suitable structure.
4-7 For hinged safety nets, rig temporary lifelines and lashing, as required, prior to lowering safety net frames to the down (horizontal) position.
4-8 Wire rope pendant thimble(s) found to have cracks or found to have portions of material broken off are a potential FOD hazard.
4-9 Quick release hook with faulty or missing pull lever retaining springs can result in unexpected disengagement of the hook, releasing the pendant assembly. This could lead to personnel injury if personnel are in safety net during disengagement. Quick release hooks with faulty or missing retaining springs can be secured by seizing pull lever to hook body using CRES seizing wire until new replacement hooks are installed.
4-10 Ensure that safety net frame is secured in the up (vertical) position. Disengage one quick release hook at a time from pendant assemblies on each frame. One pendant assembly shall always remain connected between safety net frame and ship's structure.
4-11 Latch mechanism is designed to secure safety net frame in the up (vertical) position. In this position, frame is acting as a restraint system (liferail) to prevent personnel from falling overboard or to a deck below. An improper working latch mechanism or bent/damaged frame holdback staple may lead to personnel injury should frame drop when contacted or leaned on by personnel.
