Travel:
Overnight/North America travel less than 10%.

Office Environment – May require remaining in a stationary position 50% of the time; occasional movement to access file cabinets or office equipment; requires close visual acuity for preparing and analyzing data, transcribing, viewing a computer terminal, extensive reading, and visual inspection of small parts.

Factory/field – Worker may be exposed to hazards: moving mechanical parts, vibration, moving vehicles, electrical current, temperature changes, chemicals, fumes, airborne particles, odors, dust, mists, and gases. Noise level can be loud. Requires use of safety equipment such as eye safety glasses, hearing protectors, work boots, and lab coats. May require exerting up to 25‑50 pounds of force to lift, carry, push, or pull objects.
