Fall Protection Task Group Works to Clarify Scope
The American Architectural Manufacturers Association's (AAMA) Skylight
Council's Skylight Fall Protection Task Group held a conference
call last week to review and revise its scope, in an effort to present
the scope to ASTM's task group for the "Specification of Human
Impact Criteria, with Procedure for Testing and Rating Plastic-Glazed
Unit Skylights and Related Products used on Commercial Walkable
Roofs for Fall-Through Resistance." ASTM currently is in the
process of developing a standard for skylight safety. (CLICK

"The intent of this document is to prevent a human from falling
onto a surface below," said John Westerfield of CrystaLite,
who chairs the AAMA group.
The scope excludes single-family houses from its language. "
It would be the responsibility of the homeowner to warn anyone
who's going to be on the roof," Westerfield said, to those
questioning the exclusion.
Another unidentified task group member noted that the exemption
likely has to do with the number of recorded cases of skylight falls.
"There's never been a case reported of anyone falling through
a residential skylight," he said.
Jack Riley of Arkema, however, offered another perspective-on the
scope as a whole.
"It's kind of going back to the scope, but shouldn't there
be some type of disclaimer in here, like 'no skylight will offer
protection for people in all possibilities?'" he asked. "There's
no way you can make a skylight 100-percent fall-proof, because you
never know what kind of conditions are going to come up."
However, Westerfield advised he felt the building owner and/or
contractor would still maintain responsibility for safety.
"I don't think this is replacing the responsibility of the
building owner or contractor for providing fall protection,"
One task group member noted that the National Institute for Occupational
Safety and Health's (NIOSH) document 2004-156, "Preventing
Falls of Workers through Skylights and Roof and Floor Openings,"
addresses the responsibility matter. (CLICK

Another task group member suggested that perhaps laminated glass
manufacturers should also be involved in this part of the process-particularly
with relation to weathering and how it might affect a skylight's
Westerfield brought up the fact that another option is utilizing
screens or security grilles, but that these may rust easily in a
marine climate, causing them to lose strength quickly.
"There are a lot of other things that need to be thrown into
this weathering area," said another member.
Westerfield planned to present the revised, still-in-progress scope,
to the skylight council, and to the ASTM group this week.
Many in the call were in agreement, though, that there's very little
data at this point on how many people have fallen from skylights,
how far they've fallen, who was injured, etc.
"It's very frustrating to have these instances brought up
and not have good data," said one task group member.
Westerfield was scheduled to present the group's work so far to
the ASTM group yesterday via conference call. Westerfield was unavailable
for comment at press time.
