(7) do not conduct OB/OD operations without the OE Design Center approved Work
Plan and SSHP in place and under proper supervision;
(8) use only permissible lighting in the temporary magazines and explosive storage areas;
(9) do not become careless by reason of familiarity with ammunition; and
(10) personnel will never work alone during OB/OD operations. Warning signs or
roadblocks will restrict entry to the area. One person, available in an emergency, should observe
from a safe distance while another person performs the operation.
g. Personnel will wear clothing suitable for the weather and work conditions: the
minimum for field work will be short sleeved shirt, long trousers, and leather or other protective
work shoes or boots.
h. For all activities in which USACE or contractor personnel or official visitors are
potentially exposed to foot hazards, the applicable position/activity hazard analysis, accident
prevention plan, or project SSHP will include an analysis of and prescribe specific protective
measures to be taken for reducing foot hazards.
i. Personnel will be provided with eye and face protection equipment when operations
present potential eye or face injury from physical, chemical, or radiation agents.
j. OB Specific Requirements. Personnel engaged in OB activities will be provided with
fire resistant clothing. Until authorized flame-resistant clothing is available, clothing may be
flame-proofed by immersion in an approved flame-proofing solution. Effective flame-proofing
solutions are: (1) a 15 percent aqueous solution of diammonium phosphate or ammonium
sulfamate or (2) a solution of 2 pounds of ammonium sulfate, 4 pounds of ammonium chloride
and 3 gallons of water. These are minimum effective percentages; stronger solutions may be used
without effect on wearing life of the clothing. During operations, the number of people in the
area exposed to the hazard should be kept to a minimum, but no fewer than two.
4-10. Toxic Hazards of Certain Explosives and Munitions. Many explosives, because of their
chemical structures, are somewhat toxic. When munitions are destroyed, careful attention must
be paid to the toxic nature of some of the munitions as the toxic effects of munition destruction
can vary from mild dermatitis or a headache to serious damage to internal organs. All personnel
should remain outside the PSD until all smoke and fumes dissipate.
