While performing the functions of this job, the employee is continuously required to sit, use hands to finger, handle, or feel, reach with hands and arms; regularly required to stand, walk, climb or balance, talk or hear, taste or smell; and occasionally required to stoop, kneel, crouch, or crawl. Operations requiring almost continuous attention, but work is sufficiently repetitive that a habit cycle is formed; operations requiring intermittent directed thinking to determine or select materials, equipment or operations where variable sequences may be selected by the employee.
