Does removal mean only taking the fallen tree away? Imagine that tree blocking a road. The tree is the object; the hazard is the blocked road and danger it creates. That distinction matters for wrecks too. The wreck itself and its hazard are related, but they are not the same thing. Removal is broader: it includes every action that addresses the hazard. Prevention happens before damage, stopping the hazard from occurring. Mitigation reduces the impact of a hazard already there. The road may remain blocked, but the danger is smaller. Elimination removes the hazard completely-the blockage is gone. For a wreck, then, removal is not judged only by whether the wreck is lifted away. It is judged by whether its hazard has been addressed. No. Like the fallen tree, removal includes preventing the hazard, reducing its impact, or eliminating it completely-not only taking the wreck away.
