#3 Hoist was having some electrical problems, so crew was troubleshooting it, we still had our #4 and #2 for escapeways. It ended up being 2 bad fuses. and was repaired

Crew had started shift, they were heading out to the panels they passed the shop, usually lights are on, noticed they couldn't see any light and turned around, saw it was smoke blocking the lights, started evac procedures

Bad multi-conductor in #4 shaft.

Electrical fault on our #4 Hoist. Trouble shooting determined there was crossover power from 480v to 20v that burnt up a circuit board.

Inconsistent noise coming from motor area of #3 hoist. Appears that the blower fan mounts were loose. AAI is coming in to do an in depth vibration inspection.

This was a power outage from our electricity supplier NYSEG. Power went out to underground and the decision was make to initiate a controlled evacuation at 8:38pm. all personnel brought to surface in under an hour.

Lower limit switch was not functioning properly. It was diagnosed to be faulty, corroded, moisture got inside the box. It was replaced with a new switch.

Bell line communication system was down due to corroded wire, shorting out. Electrician repaired and steps taken to prevent reoccurrence.

When 2nd shift came to surface the gate switch did not release and when the gate was opened the latch was found damaged therefor making the switch inoperable.

The #4 hoist operator noticed that the cable for the back up bell line communication system had become detached and spooled up on the top of the cage.

'Dog' braking system cammed over and wedged in the dog boxes while performing test trips.

Mine signal switch was discovered to be faulty, equipment was cleaned and replaced, test trips were done, travel resumed within 50 minutes of equipt. malfunction discovery.

Scheduled replacement of the north guides in the #3 hoist headframe was occurring. The replacement was not completed by the end of the shift, thus making #3 not usable until installation could be finished the next day. #4 and #2 hoists were still available. #3 was back in service on 10/22/23 at 6pm.

Scheduled replacement of the south guides in the #3 hoist headframe was occurring. The replacement could not be completed by then end of shift, thus making #3 not usable until install could be finished the next day. #4 and #2 hoists were still available. #3 was back in service on 10/15/23 at 3:30pm.

Output on system circuit received and electrical arc that damaged this particular output.

Power went out on surface which affected the hoist and power undergound at 4:15pm, Evac was started 4:30, power came back on at 5:20, test trips were done and operations resumed. Power outage due to storms knocking out NYSEG service.

While attempting to raise the #4 cage to surface, the electrical breaker for the charging circuit on the #4 hoist drive failed.

#3 hoist stopped due to a brake fault. The solenoid connector shorted out on one of the brake manifolds. Upon investigation it was found that in the PLC board, a rack output had shorted out which led to the shorted out solenoid connector.

Employee was using a knife to cut mesh. Employee was cutting toward themselves and slipped, causing the knife to penetrate their right thigh leading to a laceration. Employee received 2 stitches to close the wound.

2 employees were lifting a 13' long section of 6" wide rectangular steel tubing in order to set it onto a dolly. Employee one lost their grip and dropped their end. The other end then pinched employees left middle finger between the edge of the steel and concrete floor causing a nondisplaced fracture of distal phalanx of left middle finger.

Employee was setting the parking brake on a rail car. As EE tightened the brake EE felt a pop in EE's left arm. Employee was diagnosed with a tricep strain.

While performing a shaft inspection in #3 shaft, a loose wall bracket was identified. It was determined that it needed to be replaced. A courtesy call was made to MSHA as a notification.

A call was made to MSHA's hotline due to the thought that the #3 hoist brakes were not working properly. This call was made by mistake due to a misunderstanding. MSHA arrived on site on 9/6 to better understand the situation and had no findings.

On 8/8/22 an employee was attempting to open the landing gate at #4. They were trying to pull up on the latch with no success. They felt something pull/ strain in their back/shoulder area. The employee was sought medical treatment on 8/24/2022 and was prescribed physical therapy.

The west hydraulic brake for the #3 hoist was found to be out of spec during the static brake test. The east hydraulic brake and pinion brake were still functional though. MSHA was notified that the hoist was down bc of this but due to redundant braking mechanisms, the hoist was not actually down and there was no need to notify MSHA.

While performing a shaft inspection, the hoist tripped out on a drive fault. The cage was lowered to the bottom using the back up generator, then troubleshooting began. It was found that 2 of the SCRs were bad and were therefore replaced.

On 7/24 employee was helping with a belt move. Employee was pulling belt when they felt a pop in their left forearm near the elbow.

During a routine inspection an employee noticed a roof fall that appeared to have happened several weeks earlier in the Unit 80 panel within an area that was previously bermed off and blocked from personnel travel. The area was inspected the next day with an MSHA official who had no immediate concerns.

While chipping buildup in #3 shaft a small chunk of salt fell to the bottom of the shaft and pulled a wire out of a proximity switch on the way down. This caused the hoist to kick out and not run properly until the wire was repaired.
