What is the RE factor for determining New and MSD?

The correct answer for the RE factor used in determining New and Minimum Safe Distances (MSD) is 1.38. This factor is commonly employed in munitions and ordnance assessments to evaluate the potential risks associated with unexploded ordnance (UXO).

The RE factor, or Relative Efficiency factor, helps assess the explosive yield of a munition in relation to its potential impact on safety distances. A value of 1.38 is typically derived from empirical data and safety assessments based on historical incidents and statistical analysis. This ensures that the calculated MSD reflects the necessary buffer zones to protect personnel and property from the effects of an explosion.

Understanding the value of the RE factor is crucial for safety professionals working in UXO environments, as it supports effective planning and decision-making to minimize risks associated with unexploded ordnance. It embodies safety considerations in the handling, transportation, and disposal of munitions, ensuring that operations can proceed with the appropriate safety measures in place.
