(i) Surface condition.
(ii) Thickness.
(iii) Percentage of contact with the magnet.
(iv) Temperature.
(v) Metallurgical composition.
(vi) Deflection.
(b) Specified application magnets must have the rated load (capacity) either on the lifting magnet or on a tag attached to it, referring to the specific loads for which the capacity applies.
(3) Identification. All close proximity lifting magnets must be marked with the following information:
(a) Manufacturer's name and address;
(b) Model and lifting magnet unit identification;
(c) Weight of lifting magnet;
(d) Rated load, as required in subsection (2) of this section;
(e) Duty cycle, if applicable;
(f) Cold current (amps) at 68 degrees Fahrenheit ( 20 degrees Celsius), if applicable; and
(g) Voltage of primary power supply or battery, if applicable.
(h) If repaired or modified, name and address of repairer or modifier and (a) through (g) of this subsection if changed.
(4) Lifting magnets must be installed according to manufacturer's instructions.
(5) Inspection.
(a) A qualified person must inspect all new, altered, repaired, or modified lifting magnets according to Tables 24 and 25. The inspection of altered, repaired or modified lifting magnets can be limited to the parts affected, if a qualified person determines that is all that is needed.
(b) The operator must inspect the lifting magnet before and during every lift for any indication of damage. Check all of the following items:
(i) Lifting magnet face and surface of the load for foreign materials and smoothness;
(ii) Condition and operation of the:
(A) Control handle of a manually controlled permanent magnet;
(B) Indicators and meters when installed.
(c) Lifting magnets must be inspected, by the operator or another competent person, according to Table 24.
(d) A qualified person must determine whether signs of damage indicate a hazard.
(e) You must correct hazardous conditions before continuing use.
Table 24
Close Proximity Lifting Magnet Frequent Inspection
Inspect for:
How often:
Structural and suspension members for:
 
 
Deformation.
Normal service - Monthly.
Cracks.
Excessive wear on any part of the lifting magnet.
Heavy service - Weekly to monthly.
Severe service - Daily to weekly.
Special or infrequent service - As recommended by a qualified person before and after each occurrence.
 
The lifting magnet face for:
Foreign materials.
 
Smoothness.
 
Condition of lifting bail or sling suspension.
Before using, when a lifting magnet has been idle for more than one month.
Condition and operation of control handle.
 
Condition and operation of indicators and meters, if applicable.
 
 
Electrical conductors, if applicable, that are visible without disassembly for:
 
 
Loose connections.
 
 
Continuity.
 
 
Corrosion.
 
 
Damage to insulation.
 
 
Battery operated electromagnets for:
 
 
Proper level of battery electrolyte.
 
 
Corrosion of battery posts or connectors.
 
 
Cracked housings, welds, and loose bolts.
 
 
Legible labels and marking.
 
 
Note:
• Normal service means service that involves operation with various weights within the rated load limit, averaging less than 65% of rated load limits.
 
• Heavy service means service that involves operation within the rated load limit, that exceeds the limits of normal service.
 
• Severe service means service that involves normal or heavy service with abnormal operating conditions.
(f) A qualified person must perform periodic inspections of close proximity lifting magnets according to Table 25. Include the items in Table 24 of this section.
(g) You must keep dated inspection records on all critical items such as structural and suspension members, lifting magnet face, lifting bail, control handle, indicators and meters.
(h) You must correct hazardous conditions before continuing use.
Table 25
Close Proximity Lifting Magnet Periodic Inspection
Inspect for:
How often:
Members, fasteners, locks, switches, warning labels, and lifting parts for:
 
 
Deformation.
Normal service for equipment in place - Yearly.
Wear.
 
Corrosion.
Heavy service, unless external conditions indicate that disassembly should be done to permit detailed inspection - Quarterly.
All electrical components, including controllers, battery, external power supply, power disconnects, meters, indicators, and alarms for:
 
Proper operation.
Severe service - Monthly.
Condition.
Special or infrequent service - As recommended by a qualified person before the first occurrence and as directed by the qualified person for any subsequent occurrences.
Lifting magnet coil must be tested for:
 
Ohmic and ground readings compared to manufacturer's standards.
 
Note:
• Normal service means service that involves operation with various weights within the rated load limit, averaging less than 65% of rated load limits.
 
• Heavy service means service that involves operation within the rated load limit, that exceeds the limits of normal service.
 
• Severe service means service that involves normal or heavy service with abnormal operating conditions.
(6) Operational tests.
(a) All new, altered, repaired or modified lifting magnets must be tested either by or under the direction of a qualified person before use. The qualified person can limit the testing of altered, repaired or modified lifting magnets to the parts affected.
(b) The following items must be tested:
(i) Moving parts;
(ii) Latches;
(iii) Stops;
(iv) Switches;
(v) Control devices;
(vi) Alarms; and
(vii) Warning devices, including:
(A) Indicator lights;
(B) Gauges;
(C) Horns;
(D) Bells; and
