Dear Mr. Alksnis:

Thank you for your inquiry of April 29, requesting information regarding fall protection while climbing and working on a steel lattice structure resembling a communication tower. We apologize for the delay in responding.

Employers must provide employees working at heights with fall protection, such as personal fall protection systems, safety net systems, guardrail systems or other alternative fall protection. However, the information in your letter is not sufficient for us to thoroughly evaluate and respond to your concerns. If you should need a more detailed response from us, please provide us answers to the following questions:
1. How is the steel lattice structure resembling a communication tower used?

2. What type of work is required (construction, salvage, maintenance, up grading, or whatever type)?

3. Is there a citation pending involving your above concerns?
In response to additional aspects of dour inquiry, Canadian companies with employees working in the United States fall under the jurisdiction of the Occupational Safety and Health Administration (OSHA), as described in Section 4 of the Occupational Safety and Health Act (copy enclosed). The OSH Act specifies that it covers employees working in the United States, the District of Columbia, the Commonwealth of Puerto Rico, the Virgin Islands, American Samoa, Guam, the Trust Territory of the Pacific Islands, Wake Island, Outer Continental Shelf Lands Act, Johnston Island, and the Canal Zone. The only exceptions are employees of Federal Agencies, and State agencies acting under section 274 of the Atomic Energy of 1954 as amended (42 U.S.C. 2021). The exceptions are found in Section 4(b)
