Term positions do not convey permanent status in the Federal service.

The National Park Service retains the right to extend the duration of this appointment after selection and/or appointment, based on changes to the regulation governing the number of years term appointments may last.

Physical Demands: The physical effort required is considered heavy to moderate and requires lifting or handling of objects or materials up to 50 pounds unassisted, and occasionally lifting or moving heavier items with the assistance of a lifting device or other workers. The incumbent is required to work while standing, stooping, bending, crouching and climbing in tiring, awkward, and uncomfortable positions, and in all manners of environmental conditions. When working from a ladder or scaffolds, work involves reaching overhead, stretching or other awkward positions. Occasionally work is performed beneath buildings where the work area is cramped and dark, or work may be done from highly elevated platforms. Sometimes long hikes while carrying a backpack may be essential as is the possibility of technical climbing into some sites.

Working Conditions: General work is done at prehistoric and historic structures and ruins throughout the park. Often these are in backcountry locations with difficult access that may require rappelling and the use of scaffold and ladder systems. The structures and ruins may be extremely deteriorated and structurally unsound, and therefore considered hazardous. The work is often extremely dusty and direct and of such nature that protective equipment and clothing such as hard hats, safety shoes, goggles, respirators, and ear protection are required, whether working indoors and outdoors. Some work is performed in the shop area where incumbent is exposed to moderate or high noise levels from operating machinery, saw dust in the air, fumes, and hazards associated with power equipment or preservatives. Occasionally the work may be performed outside under adverse weather conditions. Other environmental factors such as stinging and biting insects, snakes, and poisonous plants can be encountered. Assignments could involve working with hazardous materials, such as rodent nests, asbestos, and lead-based products, etc. To reduce the dangers, the incumbent is required to follow prescribed safety practices.
