All workers in a controlled access zone shall be instructed to promptly comply with fall hazard warnings issued by the safety monitors. When guardrail systems are used to prevent materials from falling from one level to another, any openings must be small enough to prevent passage of potential falling objects. If guardrail systems (or chain gate or guardrail) or portions thereof must be removed to facilitate hoisting operations, as during the landing of materials, and a worker must lean through the access opening or out over the edge of the access opening to receive or guide equipment and materials, that employee must be protected by a personal fall arrest system. Each employee working on, at, above, or near wall openings (including those with chutes attached) where the outside bottom edge of the wall opening is 6 feet (1.8 meters) or more above lower levels and the inside bottom edge of the wall opening is less than 39 inches (1.0 meters) above the walking/working surface must be protected from falling by the use of a guardrail system, a safety net system, or a personal fall arrest system. OSHA considers a hook to be compatible when the diameter of the dee-ring to which the snaphook is attached is greater than the inside length of the snaphook when measured from the bottom (hinged end) of the snaphook keeper to the inside curve of the top of the snaphook. The top guardrail should rise substantially (at least 12 inches) above the eave line of the roof. or for connection to anchorages at both ends to stretch horizontally (horizontal lifeline) and that serves as a means for connecting When no other alternative fall protection has been implemented, the employer shall implement a safety monitoring system. When the path to a point of access is not in use, a rope, wire, chain, The employer must ensure guardrail systems meet the following requirements: 1910.29(b)(1) The top edge height of top rails, or equivalent guardrail system members, are 42 inches (107 cm), plus or minus 3 inches (8 cm), above the walking-working surface. A work area designated and clearly marked in which certain types of work (such as overhand bricklaying) may take place without the The purpose of the guardrail terminal platform is to reproduce to the extent practical the physical conditions under which the terminal unit was tested for its NCHRP 350 test level certification.
