(1) General.

(a) Employees must use eye and face protection equipment when machines or operations present potential eye or face injury from physical, chemical, or radiation agents.

(b) Eye and face protection equipment required by this part must meet the requirements specified in American National Standards Institute, Z87.1-1968, Practice for Occupational and Educational Eye and Face Protection.

(c) Employees whose vision requires the use of corrective lenses in spectacles, when required by this regulation to wear eye protection, must be protected by goggles or spectacles of one of the following types:

(i) Spectacles whose protective lenses provide optical correction;

(ii) Goggles that can be worn over corrective spectacles without disturbing the adjustment of the spectacles.

(iii) Goggles that incorporate corrective lenses mounted behind the protective lenses.

(d) Face and eye protection equipment must be kept clean and in good repair. The use of this type equipment with structural or optical defects must be prohibited.

(e) Table C-1 must be used as a guide in the selection of face and eye protection for the hazards and operations noted.

(f) Protectors must meet the following minimum requirements:

(i) They must provide adequate protection against the particular hazards for which they are designed.

(ii) They must be reasonably comfortable when worn under the designated conditions.

(iii) They must fit snugly and must not unduly interfere with the movements of the wearer.

(iv) They must be durable.

(v) They must be capable of being disinfected.

(vi) They must be easily cleanable.

(g) Every protector must be distinctly marked to facilitate identification only of the manufacturer.

(h) When limitations or precautions are indicated by the manufacturer, they must be transmitted to the user and care taken to see that such limitations and precautions are strictly observed.

(2) Protection against radiant energy. (a) Selection of shade numbers for welding filter. Table C-2 must be used as a guide for the selection of the proper shade numbers of filter lenses or plates used in welding. Shades more dense than those listed may be used to suit the individual's needs.

(b) Laser protection.

(i) Employees whose occupation or assignment requires potentially hazardous exposure (see WAC 296-62-09005(4)) to laser radiation must wear suitable laser safety goggles which will protect for the specific wavelength of the laser and be of optical density (O.D.) adequate for the energy involved. Table C-3 lists the maximum power or energy density for which adequate protection is afforded by glasses of optical densities from 5 through 8.

Output levels falling between lines in this table must require the higher optical density.

(ii) All protective goggles must bear a label identifying the following data:

(a) The laser wavelengths for which use is intended;

(b) The optical density of those wavelengths.

(c) The visible light transmission.
