• Instructor demonstration.• Time for student practice.• Students may perform inspection in pairs but must
independently lift, move, and land load.• While one student operates crane, another student
attaches load and gives hand signals to operator. • Students then reverse roles.• Each student must independently
complete Appendix C.

OE14316, Failure of Upper Limit Switch Causes Fuel Cask Auxiliary Hook and Block to Fall 70 FeetSummary: On June 4, 2002, with Salem Unit 1 at 100 percent power and following crane activities in the fuel building, a crane operator performed activities to stow the pendant operated 3-ton rated auxiliary hook on the fuel cask crane. The crane operator raised the hook, relying on the anti two-block switch to stop the auxiliary hoist movement. The switch failed and the hook continued to rise, snapping the cable. The block and hook fell 70 feet to the floor.
The cause of the event was a failure of the hoist upper limit switch. Follow-up testing indicated the switch would intermittently fail.
Human performance deficiencies contributed to the event in that the crane operator did not inch the hoist into the upper limit switch at a very slow speed as directed by training and procedure and he relied on the upper limit switch as a stop control during normal operation.
Corrective actions include adjusting the hoist brake, inspecting the block and hook, load testing hoist after reassembly, testing Unit 2 crane's limit switch, and inspecting other cranes limit switches. Future corrective actions include replacing the hoist cable, revising training lesson plans to emphasize not to rely on the limit switches to stop, and evaluating the installing an additional limit switch to both unit's cask handling cranes. This event is not significant because there was no damage to other equipment or personnel injury. This event is NOTEWORTHY because of the potential for serious personnel injury and equipment damage.

Appendix B
What should you know about using synthetic web slings?1. Synthetic web slings are easily cut and have poor abrasion resistance when compared with chain and wire rope
slings.2. Nylon slings are damaged by acids, but resist caustics.3. Polyester slings are damaged by caustics but resist acids.4. Sunlight, moisture, and temperatures above 90°C (194°F) damage both nylon and polyester slings.5. Use slings made of the right material for the job.6. Check the manufacturers' slings for code number and rated capacity. Reference charts showing slings and hitch
rated capacities are available from manufacturers.7. Inspect slings before using them.8. Keep an inspection record for each sling.
What should you check when selecting slings?1. Refer to the manufacturer's reference chart for the capacity rating.2. Check a sling before using it.3. Determine the weight of the load.4. Prevent loading more than the rated capacity by considering sling angle.5. Protect webbing from sharp corners, protrusions, or abrasive surfaces.6. Ensure that the sling choking action is on the webbing, not the hardware.7. Have slings repaired by a sling manufacturer only.
What should you avoid when using slings?1. Do not drag slings across floors or other abrasive surfaces.2. Do not drop slings with metal fittings.3. Do not set loads down on top of slings.4. Do not pull slings from under loads when the load is resting on the sling.5. Do not weld anything hung from a sling.6. Do not lengthen or shorten slings by tying knots.7. Do not place stitch patterns (laps) on hooks, sharp corners, or choker bearing points.
What kinds of damage make a synthetic web-sling unusable?1. Increased stiffness of sling material.2. Acid or caustic burns.3. Melted, burned or weld spatter damage.4. Holes, tears, cuts, snags.5. Broke or worn stitching. 70

Performance Step Pass Fail
1. Inspect crane control station to ensure control power switch is in off position, control station suspended by chain or aircraft cable, and controls not damaged.
2. From floor, inspect bridge and trolley area, checking for obstructions, loose or damaged equipment, and hoist rope reeved properly on drum.
NOTE: When performing steps 3 – 11, ensure that no personnel or vital equipment under hook.
3. Turn on control power switch and move hoist to clear area, if necessary.
4. Check upper hoist limit switch and down control of hoist for proper operation.
5. Check trolley for proper control response.
6. Check bridge for proper control response.
7. Lower hoist and check lifting block, hook, and hoist rope for damage.
8. Following flag person’s signals, center hook over load.
9. Attach hook and move load, maintaining sight of load or flag person, and not contacting obstacles.
10.Land load gently.
11. Secure crane by storing hook and turning off control power.
