I. Purpose & Scope
To safely and effectively provide instruction on the inspection and proper use of plate magnets.
II. Definitions
Standard PPE – High Viz Garment, Hard Hat, Z-87.1 Safety Glasses, Gloves, Pants, Work Boots
III. Process
NOTE: Work instruction does not supplement the manual. For specific instructions for the exact model please refer to the owner’s manual.
A. Potential Hazards
- Electromagnetic Field Hazard
- Falling Objects Hazard
B. PPE
- Standard PPE
C. Inspection
- Ensure magnet and surface of the load are free of dirt and debris.
- Ensure load can be lifted magnetically.
D. Use
- Do not exceed the magnet’s maximum lifting capacity. Check the weight capacity of any other piece(s) of lifting equipment being used such as a crane and account for the weight of the magnet in the load capacity.
- Check the minimum thickness measurements for the magnet. If the magnet has a minimum thickness of 10mm of steel, then applying the magnet to 1mm thick steel means 90% of the maximum capability is being lost. Thinner materials can’t absorb all the magnetism being emitted, which means they are more likely to peel away form the magnet.
- Employees with pacemakers or other active implants should stay clear of strong magnets as the electromagnetic fields (EMFs) may cause problems.
- Minimize crane swing while lifting. Keep the load horizontal to help the magnet stay firmly attached. If the crane’s swing causes the load to tip past a 10 degree angle, lifting capacity will being to fail.
- Ensure magnets are not used in conditions above their maximum operating temperature.
E. Maintenance
- Clean free of dirt, debris or moisture.
