There is no official legislation regarding medical screening of fork lift truck operators, crane operators or others in the construction injury. However, it is good practice and may be needed for insurance purposes to ensure operators are medically fit before operating a fork lift truck. It is advisable to repeat this at regular intervals up until the age of 40 and thereafter at five-yearly intervals up to the age of 65. Operators over 65 should be screened annually. A medical examination is also recommended in all cases after an accident or sickness absence that has been longer than 1 month and also after short periods of sickness if the illness may affect fitness to operate the fork lift truck.
