The employer shall ensure that each affected employee uses equipment with filter lenses that have a shade number that provides appropriate protection from injurious light radiation. Table I-1 is a listing of appropriate shade numbers for various operations. If filter lenses are used in goggles worn under a helmet which has a lens, the shade number of the lens in the helmet may be reduced so that the shade numbers of the two lenses will equal the value as shown in Table I-1, §1915.153.
Table I-1-Filter Lenses for Protection Against Radiant Energy
|Operations||Electrode size 1/32 in.||Arc current||Minimum protective shade|
|Shielded metal arc welding||Less than 3||Less than||7|
|More than 8||160-250||11|
|Gas metal arc welding and flux cored arc welding||Less than||7|
|Gas Tungsten arc welding||Less than||8|
|Air carbon||(Light)||Less than||10|
|Plasma arc welding||Less than||6|
|Plasma arc cutting||(light)**||Less than 300||8|
|Carbon Arc welding||14|
** These values apply where the actual arc is clearly seen. Lighter filters may be used when the arc is hidden by the workpiece.
Filter Lenses for Protection Against Radiant Energy
|Operations||Plate thickness-inches||Plate thickness-mm||Minimum* protective shade|
|Light||Under 1/8||Under 3.2||4|
|Medium||1/8 to 1/2||3.2 to 12.7||5|
|Heavy||Over 1/2||Over 12.7||6|
|Light||Under 1||Under 25||3|
|Medium||1 to 6||25 to 150||4|
|Heavy||Over 6||Over 150||5|
* As a rule of thumb, start with a shade that is too dark to see the weld zone. Then go to a lighter shade which gives sufficient view of the weld zone without going below the minimum. In oxyfuel gas welding or cutting where the torch produces a high yellow light, it is desirable to use a filter lens that absorbs the yellow or sodium line in the visible light of the (spectrum) operation.
