91 Conventional skylight design as it relates to health and safety issues and comparing the differences to a Solid- State Skylight Engineered/Design Solid-State Skylights

92 Traditional Skylight

93 Solid-State Skylight Glass Glazing Aliphatic Polyurethane Frame ½ Spacer Argon Gas Filled

94 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

95 Water damage from unattached gasket

96 Paint and drywall damage

97 This corner has the most water damage on the interior of the skylight

98 Aging sealant

99 Aging sealant Hail Damage

101 Aging sealant Yellowing

102 Deterioration

103 Excessive light exposure

104 Traditional skylight safety hazard SUMMARY: California FACE Report #09CA007 Aging sealant 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 skylight curb is approx. 15 tall 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.

138 Subject: Skylights: Durability of Materials We urgently need some wordsmithing volunteers to work together on "no plastic 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 me with your willingness to help review changes to Co- Chair John Westerfield's below. Thanks very much: Nigel

139 From: John Westerfield Subject: Durability of Materials As it regards to the criteria for plastic glazing, the following is what the ASTM Work Group has approved For plastic infill on a unit skylight test specimen, at least two separate layers of plastic glazing meeting the durability criteria in Section 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? Thank you, -John -- John Westerfield CrystaLite, Inc Cedar Street, Everett, WA p: f:
