    3. 3. The Users ResponsibilitiesThe Users Responsibilities
    4. 4. All candidate for the Crane and Hoist operation job should be in the interest of safety and be able to meet the minimum requirements before being considered for training. The basic requirements are as follows: Must pass Hearing and Vision Testing per State Requirements.
    5. 5. Age Most state laws, which govern the operations, require that a person shall have passed their 18th birthday before being allowed to operate an overhead crane.
    6. 6. Vision Standard visual acuity of 20/20 should be met. This can be measured by a number of devices. Color vision should be checked and field of vision should be determined.
    7. 7. .Reaction Time Measures how quickly the person reacts to a set of signals or to an emergency. (The Up Button sticks closed)
    8. 8. Distance Judgement Measurement of depth perception is important for Crane Operators. Hearing Several devices are available to test hearing ability. The person should be able to meet standard requirements.
    9. 9. General Health The company doctor should determine the physical fitness of the individual. Any tendencies toward heart trouble, epilepsy, dizzy spells, diabetes, high blood pressure, or physical defects should be studied to determine physical fitness. If the doctor approves of an individuals physical condition, the candidate should be considered as having passed this phase of the requirements. Physical Examination A urinalysis and blood serology test should be given to every candidate for a Crane Operator’s job. If the individual meets standard requirements they can be considered as having passed this phase of the requirements.
    10. 10. Literacy Most state laws that govern the operations, site that an individual must be able to read and write in English before being allowed to operate an overhead crane. This list is the minimum suggested requirements generally recognized by most states.
    11. 11. SAFETY RULES There are many safety rules that have been set up to be observed by Crane Operators. However, if you follow these rules you will observe most of the necessary precautions while operating your crane. .
