MIL-STD-1472E
5.13.7,4 Toxic hazards.
5.13 .7.4.1 General Personnel shall not be exposed to the concentrations of toxic substances in
excess of the limits specified in either the Department of Defense (DoD) Occupational Safety and
Health (OSH) standards or specialized standards applicable to military unique equipment, systems or
operations.
5.13 .7.4.2 Carbon monoxide. Carbon monoxide (CO) in personnel areas shall be reduced to
the lowest level feasible. Personnel shall not be exposed to concentrations of CO that will result in
carboxyhemoglobin (COHb) levels in their blood greater than
5% for all system design objectives and
aviation system performance limits and 10% for all other system performance limits. Such COHb
blood levels my be estimated by solving the empirical equation in paragraph 5.13.7.4.5 of MIL-
I-IDBK-759. When using the equations to estimate the percent COHb blood levels for combat vehicle
occupants, the following work stress }eveIs(defined by MIL-HDBK-759) shall be applied as
appropriate: activities involving weapons fw: level 4; all other mission activities: level 3. An initial
value of COHb = 1.0% shall be assumed for all estimates.
5.13.7.5 Radiation. The design of radiation emitting systems and equipment shall minimize
hazards to operators and maintenance personnel. If internal ionizing radiation hazards (e.g., breakage
of a tritium-ilh.minated source in a fn-control device or rifle sight pnxents potential tritium ingestion
by individuals in the area) cannot be eliminated, they shall be mhimizd
through engineering design.
Ionizing radiation exposure rates produced by any device shall not exceed 0.5 rnilliroentgenshr at a
distance of 5 cm (2 in) from any point on the external surface. Microwave, radio frequency, X and
laser radiation limits should conform to those specified in Guideline 1, MIIADBK454. Definitive
and specific data shodd be obtained from the service agency responsible for control of personnel
exposure to radiation.
5.13.8 Trainem Training materials, devices, simulators, and other equipment using
embedded traimng, should incorporate safeguards, safety warnings, and procedures developed for the
remainder of the system.
5.13.9 Stedthandcovatope
riitiOXIS. systems and equipment for use in COLdMt IiUty require
stealth for covert operations. The need for low4mmmble exterior and camouflage may preclude the
use of brightly colored warning signs, warning lights, or auditory alarms. For such systems and
equipment, techniques, such as barriers and interlocks, shall be used to ensure safe operations.
