Additional Information:

Working Conditions: A Mechanical Technologist observes or monitors flow meters, amp meters and pressure gauges to determine compliance with prescribed operating or safety standards. Working with color coded wires and pipes requires the ability to discriminate among and match colors. Micrometers, calipers and other calibrated instruments are used when machining parts. Operating equipment such as drills, lathes and milling machines requires making precise arm-hand position movements, fine, highly controlled muscular movements to adjust the position of a control mechanism, and standing for extended periods of time unable to sit or rest at will. Finishing grout and wrenching bolts requires making continuous or repetitive arm-hand movements. Assembling valves and using a micrometer involves making skillful, controlled manipulations of small objects. Breaking loose large bolts uses explosive strength. Operating a forklift or crane requires coordinating the movement of more than one limb simultaneously. Working on piping and engines involves bending or stooping repeatedly or continually over time. Working on overhead piping requires lifting arms above shoulder level. Work is performed in sumps, vaults, galleys, and other small, cramped areas and involves sitting for extended periods of time with the ability to change positions. Work on overhead piping, conveyors, and roof-mounted equipment is performed at heights greater than 10 feet. Work at pump sites in the field requires walking over rough, uneven, or rocky surfaces and is performed in a variety of weather conditions with exposure to the elements. A Mechanical Technologist must be able to hear alarms and carry gas-filled bottles and equipment weighing more than 50 pounds more than 20 feet. Some work is performed in enclosed spaces with exposure to temperatures as high as 120 degrees Fahrenheit. Mechanical Technologists must be capable of wearing various types of respirators as Personal Protective Equipment (PPE).
