1910.133: Eye and Face Protection in General Industry

By Black Belt Safety Editorial Team Official text as of octubre 15, 2026 Data updated noviembre 5, 2026 3 min read

In plain words:

Employers must make sure each worker uses proper eye or face protection when exposed to flying particles, molten metal, liquid chemicals, acids or caustic liquids, chemical gases or vapors, or harmful light radiation. Side protection is required for flying objects, prescription wearers need protection that covers their prescription, and protection must meet ANSI Z87.1.

(a) General requirements. Open (a) 1,372 citations

(1) The employer shall ensure that each affected employee uses appropriate eye or face protection when exposed to eye or face hazards from flying particles, molten metal, liquid chemicals, acids or caustic liquids, chemical gases or vapors, or potentially injurious light radiation. Open (a)(1) 1,256 citations

(2) The employer shall ensure that each affected employee uses eye protection that provides side protection when there is a hazard from flying objects. Detachable side protectors (e.g. clip-on or slide-on side shields) meeting the pertinent requirements of this section are acceptable. Open (a)(2) 24 citations

(3) The employer shall ensure that each affected employee who wears prescription lenses while engaged in operations that involve eye hazards wears eye protection that incorporates the prescription in its design, or wears eye protection that can be worn over the prescription lenses without disturbing the proper position of the prescription lenses or the protective lenses. Open (a)(3) 76 citations

(4) Eye and face PPE shall be distinctly marked to facilitate identification of the manufacturer. 1 citations

(5) The employer shall ensure that each affected employee uses equipment with filter lenses that have a shade number appropriate for the work being performed for protection from injurious light radiation. The following is a listing of appropriate shade numbers for various operations. Open (a)(5) 13 citations

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 60 7
3-5 60-160 8
5-8 160-250 10
More than 8 250-550 11
Gas metal arc welding and flux cored arc welding less than 60 7
60-160 10
160-250 10
250-500 10
Gas Tungsten arc welding less than 50 8
50-150 8
150-500 10
Air carbon (Light) less than 500 10
Arc cutting (Heavy) 500-1000 11
Plasma arc welding less than 20 6
20-100 8
100-400 10
400-800 11
Plasma arc cutting (light)** less than 300 8
(medium)** 300-400 9
(heavy)** 400-800 10
Torch brazing 3
Torch soldering 2
Carbon arc welding 14
Filter Lenses for Protection Against Radiant Energy
Operations Plate thickness—inches Plate thickness—mm Minimum* Protective Shade
Gas Welding:
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
Oxygen cutting:
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.
** These values apply where the actual arc is clearly seen. Experience has shown that lighter filters may be used when the arc is hidden by the workpiece.

(b) Criteria for protective eye and face protection. Open (b) 6 citations

(1) Protective eye and face protection devices must comply with any of the following consensus standards: Open (b)(1) 6 citations
