What does the term graze sensitive mean in relation to fuzes?

The term "graze sensitive" in relation to fuzes specifically refers to the ability of a fuze to be initiated by grazing the surface. This means that the fuze is designed to trigger when it comes into contact with a surface, indicating that even a small physical interaction can result in detonation. This characteristic is particularly important in some types of ordnance where contact with a target may be fleeting or incidental, yet still needs to result in an effective response. Understanding this sensitivity is crucial for EOD personnel to assess the risks associated with handling or proximity to such devices.

The other options describe different aspects of fuze behavior but do not accurately define "graze sensitive." While malfunction during deployment and sensitivity to environmental conditions are important considerations in fuze reliability, they do not pertain to the specific mechanism of initiation through grazing. Similarly, the design to avoid premature detonation speaks to a separate safety feature in fuzes that is unrelated to the sensitivity described by the term "graze sensitive."
