What type of injury can result from a miniature detonator cord in an aircraft canopy if proper life support equipment is not used?

The correct answer highlights the risk of foreign material in the eyes and/or facial burns produced by a miniature detonator cord in an aircraft canopy. When explosive charges like detonator cords are used in aviation contexts, they can create hazardous debris and hot gases upon detonation. This can lead to shrapnel that could easily enter the eyes or strike the facial area, potentially causing severe injuries.

The use of proper life support equipment, such as face shields or goggles, is critical in mitigating these risks by providing a barrier that protects the eyes and face from potentially damaging materials. An absence of adequate protective gear can leave individuals exposed to these types of injuries, emphasizing the importance of safety precautions in high-risk situations like those involving explosives in aviation.

Other options, while they could occur in different scenarios or contexts, are less directly related to the specific hazards presented by a detonator cord. Foreign material and burns are immediate and likely outcomes given the explosive environment, making this answer particularly relevant and correct in this context.
