This would be with the arms over head, or it may involve kneeling or crouching on the floor to work on wall plugs located at 12 inches off the floor.
This task involves reaching, stooping, handling and fingering. Occasionally, it involves lifting and carrying boxes of fixtures weighing as much as 50 pounds.
- Drilling Studs
The electrician drills studs through the wall with a one-inch auger. The sequence of drilling varies according to the product line used. The electrician will crouch or stoop when drilling these studs located 18 inches from the floor, and will stand on the ladder with the arms overhead when drilling at various heights.
This task involves reaching, stooping, handling, fingering, twisting and turning.
- Pulling Wires
This requires the electrician to pull wire to appropriate fixtures, outlets or plug receptacles. Pulling the wire may involve standing on
a ladder while working at various heights with the arms extended overhead, or it may involve kneeling or crouching on the floor to work at 12 inches above floor level.
This task involves pulling, handling, fingering, some twisting and turning. Occasionally, it may involve lifting and carrying boxes of wire. Each box contains wire weighing anywhere from 5 to 50 pounds. The size of the wire used and the number of boxes needed varies from job to job. If the weight of boxes of wire exceeds 50 pounds, a co-worker would be available to assist the electrician with the lifting and carrying activities.
