Fall Protection

… Fall protection during climbing is necessary part of fall safety. However, climbers sometimes faced with climbing in areas with inadequate anchorage points (typically during antenna climbing). In these cases, first man up carries and attaches safety rope for use during time of work performance. Fall protection rope removed when all work completed.

Fall Prevention

… Though free climbing not authorized, antenna manufacturers do not presently have way to provide fall protection that meets minimum anchorage requirements.

First man up attaches safety line. Once attached, all others can attach to it. Depending upon the number of personnel on the antenna, more than one rope may be required.

The use of portable type anchorage points can make difficult attachment locations safe. Cross arms shown here are one such means.

Climber is attached with fall protection lanyard and positioning device.

Climber is using a cross arm anchorage point to allow him to work in an area that does not have an adequate anchorage point.

Climber is transferring from one anchorage point to another.

Proposed Rule The following NOT in place and NOT

currently a rule: “Qualified climber” is term used in

tower industry and by National Association of Tower Erectors (NATE)

Though term used, still not an accepted principle by OSHA

Excerpt From Proposed Change “Federal Register”

Vol. 55, No. 69 April 10, 1990 1910 Walking and Working Surfaces

and Personal Protective Equipment (Fall Protection Systems)

Proposed Rule (under ladders) Indeed, OSHA believes that the

amount of time employees would spend installing, inspecting and maintaining fall protection on fixed ladders could substantially exceed the amount of time that ‘qualified climbers’ would be spending to climb the ladders.

Proposed Rule Therefore, as an alternative, OSHA

believes it appropriate to allow “qualified climbers” as defined by OSHA to climb these ladders without fall protection under certain conditions.

Proposed Rule First, the employer would have to

certify that the employee is a “qualified climber,” as provided in 1910.32(b)(5) of this proposal.

Second, once the “qualified climber” reaches a work station, the employer would be required to provide appropriate fall protection.

Proposed Rule “Qualified climbers” as provided in

1910.23(a)(2), ladders and step bolts on triangulation, telecommunication electrical power towers and poles and similar structures, including stacks and chimneys, need not have ladder safety devices, cages or wells if only “qualified climbers” are permitted to use these ladders or step bolts. Such “qualified climbers” shall meet the following requirements.

Proposed Rule (i) “Qualified climbers” shall be

physically capable (demonstrated through observations of actual climbing activities or by a physical examination) of performing the duties which may be assigned them.

Proposed Rule (ii) “Qualified climbers” shall have

successfully completed a training or apprenticeship program that covered hands-on training for the safe climbing of ladders or step bolts and shall be retrained as necessary to ensure the necessary skills are maintained.

Proposed Rule (iii) The employer shall ensure

through performance observations, and formal classroom or on the job training, that the “qualified climber” has the skill to safely perform the climbing.

Proposed Rule (iv) “Qualified climbers” shall have

climbing duties as one of their routine work activities and

(v) “Qualified climbers,” when reaching their work position, shall be protected by a fall protection system meeting the requirements of 1910.28.

Proposed Rule 1910.268 Telecommunications (g) Personal climbing equipment – (1)

General body belts and pole straps shall be provided and the employer shall ensure their use when work is performed at positions more than four feet (1.2m) above the ground, on poles and on towers, except as provided in paragraphs (n)(7) and (n)(8) of this section.

Proposed Rule … Personal fall protection systems shall

meet the applicable requirements set forth in Subpart I of this part. The employer shall ensure that all climbing equipment is inspected prior to each day’s use to determine that it is in safe working condition.

Proposed Rule … Production samples of personal

fall protection systems shall be certified by the manufacturer or a qualified person as having been tested in accordance with and as meeting the requirements of Subpart I of this part as applicable.

Remember Currently no program for “qualified

climbers” However, if company set up for a

“qualified climber” program, the proposed rules would be a minimum starting point for establishing safe climber’s program

Remember Absolute best method for

maintaining climber safety is 100% fall protection

Remember Accidents from falls do not have

to be from towers Can happen from any height, so

think about what you are doing
