What thickness do barricades need to be determined based on caliber?

Barricade thickness is essential for safety when dealing with unexploded ordnance (UXO), as it helps to mitigate the effects of potential detonations. The proper thickness of barricades is determined based on the caliber of the ordnance.

For ordnance that is more than 105mm, a thickness of 3 feet is deemed necessary to effectively absorb and redirect the force of an explosion, ensuring a higher level of safety for personnel and equipment in the vicinity. Conversely, for ordnance that is less than 105mm, a thickness of 6 feet is recommended. This distinction reflects the varying explosive potential and fragmentation characteristics of different calibers.

Thus, the guidelines indicate that both conditions are required: barricades must be 3 feet thick for ordnance greater than 105mm and 6 feet thick for ordnance less than 105mm. This comprehensive approach to barricade construction provides an effective means of protection in UXO handling and response scenarios.
