(5) Ensure that appropriate personnel are included in an ocular surveillance

program (DASG Memorandum, 11 April 1994, paragraphs 4., 5., and 7.; ANSI

Z136.11993 paragraph 6.; AR 4046 paragraph 16.; CECOM 38510 paragraph

6.d.(6)).

(6) Never direct laser beams at personnel (CECOM 38510 paragraph 8.b).

(7) Do not look into the laser beam or specular reflections of the beam since

power or energy densities may exceed the safety standards (CECOM 38510, para-

graph 8.b).

(8) All personnel who could be reasonably expected to be exposed to harmful

levels of laser or optical radiation will wear appropriate protective eyewear. Ensure that

all laser protective eyewear provides the adequate optical density protection for the

wavelength(s) of any laser being used (TB MED 524, paragraphs 323, 327.b and

327.c; TG081; FM 850, paragraph 4.a; CECOMR 38510, paragraphs 7.e and

8.e).

(9) Avoid aiming a laser with the naked eye. This prevents looking along the

axis of the beam and decreases the hazard from any potentially hazardous reflections

of the beam (FM 850, paragraph 4.b).

(10) Work with lasers will be done in areas of high general illumination when

possible (except for night operations and any other operation which requires low light
