Engineered / Designed Support Systemsfor the Management of Dead Weight
Forward Thinking Innovative.Sustainable.
There are better solutions:
Successfully meeting the parallel demands in the management of dead weight
Star Components of Engineered/Designed Support Systems
Telescoping Channel System
Polypropylene Base
Variations of the polypropylene base designs- 18” X 18” Square Base, 18” Round Base- 8” X 10” Base, 10” X 16” Base, 12” X 12” Base
The Hot Dip Galvanizing Component of Telescoping Channel
• All channel and fittings should be fabricated from steel with hot dip galvanizing for G90 specifications, with a zinc coating on all surfaces, including edges and welds
• This provides 20 plus years of protection in most atmospheric/industrial environments
• Use of Zinc rich paint applied to field cuts, provides immediate and long term protection

Why traditional skylights fail
• Uses numerous metal parts, which are susceptible to wide temperature fluctuations, large hail and other extreme weather conditions
• Utilizes silicon sealants which age rapidly, leading to vulnerabilities, therefore causing the inevitable water leaks
• Materials cannot allow for expansion and contraction

Traditional skylight safety hazardSUMMARY: California FACE Report #09CA007
A 56-year-old warehouse worker died when he fell through a skylight on the roof of a warehouse. The victim had been allowed to climb onto the roof to service an air conditioning unit. This was not part of his usual duties. The victim’s employer did not have procedures for working on the roof. The CA/FACE investigator determined that, in order to prevent future incidents, employers of warehouse workers should ensure that house workers do not perform any duties outside the scope of their normal assignment.

Certifications
• OSHA Fall Protection Test - A 300 lb. weight representing an average adult person, is dropped from a height of 5 feet directly on the center and failed to penetrate the skylight
• AAMA Ice & Snow Loads Test - Tested to 504 psf = 8,064 lbs. Performs equally on both sloped and flat roof systems
Testing
• Miami-Dade Large Missile Impact Test - An 8 foot 2’ x 4’is shot twice from a cannon, once in the center of the light, and again in the corner. The projectile failed to penetrate the light
• Class 4 Large Hail Test - A 2” ice ball is shot at the light from a cannon at 120 mph. Single piece skylight suffered no visible damage
Testing
• Miami-Dade Cyclic Test - 90 psf of alternately +/- air pressure is applied against the over 5,000 cycles; solid state skylight suffered no cracks or tears
• AAMA 313-10 and AAMA 113-11 - The Aliphatic Polyurethane frame materials were evaluated and passed in every category; the only skylight to test successfully and receive certification per the
requirements of the AAMA 313-10 material standard
Our test, submerged since 2008 in water with rapidly altered temperatures, is still completely leak free.

Subject: Skylights: Durability of Materials
We urgently need some wordsmithing volunteers to work together on "noplastic skylights" (unless metal screened) because of inadequate resistance to uv light and unreliability likely resulting in loss of life at an undetermined time. Remember John Newquist retired OSHA ARA who said that skylights break like eggshells
Check out my findings the day before our last Skylight meeting with regard to the reliability (or unreliability) of the Miami-Dade requirements now in our standard.
Thank you: the time is now to help put new skylight deaths behind us in the USA
Help! Please email me with your willingness to help review changes to Co-Chair John Westerfield's email below. Thanks very much:Nigel
From: John Westerfield [mailto:[email protected]] Subject: Durability of Materials
As it regards to the criteria for plastic glazing, the following is what the ASTM Work Group has approved.4.1.2 For plastic infill on a unit skylight test specimen, at least two separate layers of plastic glazing meeting the durability criteria in Section 5.1.2 must be utilized.
After outdoor exposure in South Florida at 45 degrees south inclination for 5 years or to Xenon Arc utilizing a 6500 watt lamp per ASTM G155 (Method 1) (Relative Humidity 50 +/- 10%, Temperature set point of 47 C, Daylight filters) for a period of 4500 hours; tensile test per ASTM D638 on exposed and non-exposed samples. Maximum allowable difference: +/- 10%.
Glazed portions of test specimens that have not been shown to meet the durability requirements of Section 5 shall have the glazing removed prior to impact testing.
In lieu of this language, what specific language do you propose for this Specification / Test Method?
