NAC513.340. Rating of degree of danger.
- The degree of danger for a dangerous condition must be rated in the following manner:
1. One point must be assigned to a dangerous condition consisting of:
(a) A vertical or near vertical hole 8 to 20 feet, inclusive, in depth and highly visible upon approach;
(b) An inclined hole less than 50 feet deep from which a person could climb out;
(c) A horizontal hole with no associated stopes, winzes or raises; or
(d) A high wall of an open pit.
2. Two points must be assigned to a dangerous condition consisting of:
(a) A vertical or near vertical hole 8 to 20 feet, inclusive, in depth which is not visible upon approach;
(b) Any vertical or near vertical hole 20 to 50 feet, inclusive, in depth; or
(c) Any inclined hole greater than 50 feet deep from which a person could climb out with no associated stopes, winzes or raises.
3. Three points must be assigned to a dangerous condition consisting of:
(a) Any vertical or near vertical hole 50 to 100 feet, inclusive, in depth; or
(b) Any horizontal or inclined hole with associated stopes, winzes or raises with less than a 20-foot vertical opening.
4. Four points must be assigned to a dangerous condition consisting of:
(a) Any vertical or near vertical hole which is at least 100 feet deep and visible upon approach; or
(b) Any horizontal or inclined hole with associated stopes, winzes or raises with a vertical opening greater than 20 feet.
5. Five points must be assigned to a dangerous condition consisting of any vertical or near vertical hole which is at least 100 feet deep and not visible upon approach.
Ê The Administrator or his or her representative may assign a higher degree of danger to a dangerous condition if other factors such as loose ground or the presence of water increase the danger, but the degree of danger for a single dangerous condition may not be scored higher than five points.
