1.1To establish fall-through resistance criteria for skylight openings on nonresidential and low-slope roofs. The intent is to prevent a human from falling through the opening after impact. 1.2The requirements of this standard apply to the installation of new unit skylights or related product on any applicable building. 1.3This specification does not apply to multi-panel skylights such as, but not limited to,, site-built systems or sloped glazing. 1.4This standard can also be applied to workers that come in contact with unit skylights and related products installed on the same low-slope roof surface upon which they may be permitted to work. It anticipates several potential occupational exposures to risk of injury from a fall through a skylight opening, but does not claim to have foreseen all such risks that might develop over time. 1.5Conformance with this specification is not required where other means of providing protection for open holes exist such as permanent guardrails or curbs built with a minimum height of 42 inches. 1.6This specification is not intended for products installed over rectangular openings 12 inches or less in any dimension, or circular openings no smaller than 18 inches across.
