Physical Effort: This position is required to perform masonry work from ladders, scaffolds, platforms, and other cramped and hard-to-reach places. Duties require the incumbent to sit, stand, stoop, bend, kneel, climb, crawl, and work in uncomfortable positions. If the incumbent is assigned to perform masonry work in remote locations, the incumbent may be required to walk, hike, climb, or drive over rough and uneven terrain. The incumbent is expected to lift and/or carry items up to 50 pounds unassisted, and occasionally up to 100 pounds in weight with assistance. Working Conditions: Most work is performed outside with exposure to all types of harsh weather conditions. Work outside may be subject to extreme weather conditions, with wind, rain, snow, and ice, in temperatures ranging from below to over 100 degrees. Depending on the geography of the park unit assigned, work may take place at elevations ranging from sea level up to 10,000 feet or in or near bodies of water. The incumbent may be regularly exposed to dust, dirt, fogs, mists, gases, smokes, sprays, and vapors, as well as noise, vibration, cuts, bruises, and abrasions from the use of masonry tools, vehicles, hoists, conveyer belts, cranes, and other equipment. The incumbent may occasionally be exposed to hazardous materials that can cause skin, eye, and respiratory irritation and burns, as well as microbiological organisms and potentially hazardous wildlife. The incumbent is subject to the danger of falling when on ladder or scaffolding, and broken bones as a result of accidents while driving or when loading and unloading equipment and materials. Some contact may be necessary with chemical agents in the nature of cleaning fluids and preservation compounds, some of which are considered hazardous.

The incumbent is expected to comply with all safety and occupational health requirements and wear protective clothing, gloves, face shields, and in some cases a respirator that may be uncomfortable. Career-Seasonal appointments are permanent positions and include the same benefits as Career appointments, but do not provide work on a year-round basis. You will work from approximately 6-9 months (or more depending on the park) and you will be in a non-pay status for approximately 3-6 months (or less depending on the park). Non pay status is dependent on the location of the position being hired.
