Final answer:
No, it is not true. Ladders are just one of the options, and other means of access can also be used depending on the workplace requirements.
Step-by-step explanation:
No, it is not true that 1 double-cleated or 2 single ladders are the only means of access for 25 or more employments. The statement seems to be referring to OSHA general industry standards for ladder safety, which state that for every 25 employees, there should be at least one stairway, ladder, or other safe means of access and egress. This means that ladders are just one of the options, and other means of access can also be used depending on the workplace requirements.
