an obstruction to deter the passage of persons or vehicles. Section 1926.203(a) of Part 1926 Subpart G (Signs, Signals, and Barricades). Although these definitions vary, they typically describe a device that delineates and warns of a boundary that is not to be crossed. However, that term is defined in other OSHA standards. The term 'barricade' is not defined in Subpart N. In 29 CFR Part 1926, Subpart N (Cranes, Derricks, Hoists, Elevators, and Conveyors), §1926.550(a)(9) states: Accessible areas within the swing radius of the rear of the rotating superstructure of the crane, either permanently or temporarily mounted, shall be barricaded in such a manner as to prevent an employee from being struck or crushed by the crane. Question 1: Does caution tape attached to a crane, forming a perimeter around the crane's swing radius, meet the barricade requirement under §1926.550(a)(9)? We have paraphrased your questions as follows: You also ask about what safety requirements under §1926.416 apply for protecting employees working with portable welders from electrocution. You ask if caution tape or rope will serve as adequate barriers around a crane's swing radius under §1926.550(a)(9). This is in response to your letter dated July 3, 2003, to the Occupational Safety and Health Administration (OSHA). Re: Will a caution tape or rope perimeter satisfy the requirement in Subpart N, §1926.550(a)(9), for a barricade around a crane's swing radius? Does OSHA require specific protection for cable terminal connectors on portable welders?
