PHYSICAL REQUIREMENTS: 

The work environment characteristics described here are representative of those an employee encounters while performing the essential functions of this job. 

Functions involve the periodic performance of moderately physically demanding work, usually involving lifting, carrying, pushing and/or pulling of moderately heavy objects and materials (up to 25 pounds). Tasks that require moving objects of significant weight require the assistance of another person and/or use of proper techniques and

moving equipment. Tasks may involve some climbing, stooping, kneeling, crouching, or crawling. Must be able to safely operate assigned vehicles possibly long distances. 

 ENVIRONMENTAL REQUIREMENTS: 

The work environment characteristics described here are representative of those an employee may encounter while performing the essential functions of this job. 

Functions are regularly performed inside and/or outside with potential for exposure to adverse conditions, such as inclement weather, atmospheric elements and pathogenic substances. The noise level in the work environment is usually moderate.
