(e) Ground and discharge live circuit points prior to performing mainte-
nance procedures (ANSI Z136.11993, Appendix F1.1).
(19) Potentially hazardous Xray radiation may exist near certain highvolt-
age power supply tubes. Adequate shielding shall be employed where necessary (ANSI
Z136.11993, paragraph 7.4.1).
(20) Use shorting devices on large capacitor banks and high power supplies,
to drain off high voltage charges once power to the unit has been removed.
(21) Personnel will be aware of fire hazards associated with laser systems
(ANSI Z136.11993, paragraph 7.5).
(22) Have first aid personnel with appropriate training and equipment avail-
able at a level commensurate with the associated laser hazards (electrical, thermal,
chemical, cryogenic, etc.) (CECOMR 38510, paragraph 7.f).
(23) Medical examinations for laser users will be performed prior to working
with the laser, following any suspected laser injury, and upon termination/relocation, in
accordance with (IAW) DASG Policy Letter, Vision and Ocular Assessments of Person-
nel in Laser and Radiofrequency Radiation Environments, 11 April 1994.
(24) Interlocks. Overriding of the laser protective systems (i.e. interlocks) re-
quires the development of a temporary laser controlled area. That area shall be posted
and meet all safety requirements inside and outside (ANSI Z136.11993, paragraph
7. Hazard Evaluations. As part of the safety release process for all standard CECOM
items of supply, USACHPPM performs hazard evaluation surveys on all radiofrequency
and optical radiation producing equipment. All CECOM equipment survey requests are
sent through the CECOM Directorate for Safety (DS), ATTN: AMSELSFRE, Fort
Monmouth, NJ 077035024. Hazard evaluation surveys are required for the following:
a. All newly fielded systems during the research, development, test, and evalua-
tion (RDT&E) phase.
b. New configurations of fielded systems that change the output power or char-
acteristics of the radiation produced.
8. Accident Reporting Procedures. In the event of a suspected overexposure from a
radiofrequency or optical radiation source, the following procedures should be followed:
a. Immediately disconnect the power from the equipment that caused the poten-
tial overexposure and identify and secure the equipment. Do not alter the configuration
of the equipment. In the case of an RF system, do not remove, cut, or destroy a
cracked or open waveguide that has caused a potential overexposure. These items
must be inspected by the authorities conducting the incident/accident investigation
