What is crucial for constructing artificial high directionals?

The construction and rigging of artificial high directionals must ensure maximum reliability and safety during a rescue scenario. When one refers to something being "100% bombproof," it emphasizes the need for robust and fail-safe design principles. An artificial high directional serves to redirect forces and maintain stability during a rescue operation, so it is vital that the materials and rigging used can withstand the expected loads without failure. This level of assurance in construction minimizes risks to the rescuers and the victim, making it a fundamental requirement in rope rescue techniques.

While attributes like lightweight materials and ease of identification can be beneficial, they do not compromise the structural integrity that is paramount for high directionals. Additionally, attempting to set up such a system without proper knowledge would increase the likelihood of mistakes or failures, which the safety standards in rescue practices aim to avoid. Therefore, the emphasis on it being "100% bombproof" directly relates to the critical nature of safety in rescue operations.
