Even though the NCCCO certification medical form was not mandatory by any federal and state organizations. It was adopted as the standard for certification for crane operators.

It now refers to the ASME B30 medical standard or defers to the DOT medical Certification

ASME B30.5-3.1.2 (a) in order to be certified by CIC.

1.   Vision of at least 20/30 Snellen in one eye and 20/50 in the other, with or without corrective lenses.

2.   Ability to distinguish colors, regardless of position, if color differentiation is required.

3.   Adequate hearing to meet operational demands, with or without a hearing aid.

4.   Sufficient strength, endurance, agility, coordination, and speed of reaction to meet crane operation demands.

5.   Normal depth perception, field of vision, reaction time, manual dexterity, coordination, and no tendencies to dizziness or similar undesirable characteristics.

6.   Negative results for a substance abuse test. (The level of testing determined by the standard practice for the industry where the crane is employed and confirmed by a recognized laboratory service.)

7.   No physical defects or emotional instability that could render a hazard to myself or others, or which, in the opinion of the examiner, could interfere with my performance operating the crane. If evidence of this nature is found, it may be sufficient cause for disqualification.

8.   Not subject to seizures or loss of physical control; such evidence shall be sufficient reason for disqualification. (Specialized medical tests may be required to determine these conditions.)
