• B. He, Frag, Move, Jet, Pe
• C. He, Frag, Move, Jet, Pe, Emr
• D. He, Frag, Move, Jet, Pe, Emr, Static

Answer: (D)

The main idea here is that rifle grenades carry multiple simultaneous safety hazards due to their explosive contents and how they’re used. To protect personnel, you have to account for all the different ways the device could cause harm, not just one or two.

Heat is a hazard because residual heat or nearby heat sources could ignite sensitive materials or affect the fuse and detonation timing. Fragmentation is the classic risk with high-explosive fills—the grenade can shatter into high-velocity fragments that can injure nearby personnel or damage equipment. Movement concerns arise because handling, loading, or accidental jostling could cause the grenade to shift or fire unintentionally, creating a risk of injury or misfire.

Jetting refers to the dangerous jet of hot gas and fragments that can be expelled during detonation, which can travel at high speed and strike people or objects at a distance. The Pe hazard covers pressures or energy effects related to the propellant or explosive mass, including overpressure and impulse that can affect nearby structures, equipment, or bystanders. EMR (electromagnetic radiation) represents electromagnetic effects or interference that can accompany detonation or the explosive train, potentially impacting nearby electronics or signaling devices. Static highlights the danger from static electricity, which under certain conditions could ignite sensitive energetic materials.

Choosing the option that includes all these hazards—heat, fragmentation, movement, jetting, pressure/propulsive effects, EMR, and static—ensures safety plans and handling procedures address every feasible risk. Omitting any one of these hazard types would leave a gap in protection, so the comprehensive set is the best choice.
