Guidelines for the installation of metal safety treads or nosings into new concrete or steel pan-filled stairs

• The use of very large aggregate in the concrete mix may make placement of the safety nosing difficult.
• Safety nosing placement may be difficult in concrete with very low slump
• Place the concrete into the stair forms or steel pans as quickly as possible; schedule pours so as to install the metal safety nosings quickly, before the “initial set” of the concrete occurs.
• Puddle the concrete, tamp the safety nosings to insure proper concrete formation around the anchors.
• Remove protective tape as soon as practical
• Close stairway after pour; permit no use for 24 hours
