To protect themselves against fall hazards in a slab-column frame, workers use the row of shoring jacks installed at 1 m from the edge as supports for on-site built guardrails. Inspectors of the Quebec Workers Compensation Board (Commission de la sante et de la securite du travail (CSST)) have expressed concern about the safety and compliance of these on-site built guardrails with the Quebec Safety Code for the Construction Industry (S-2.1, r.4). Some workers have also inquired if the shoring jack can be used as an anchor for a travel restraint system. The present study describes how an evaluation method and a test protocol have been used to verify if guardrails built on-site, with shoring jacks as supports, are safe and comply with the requirements of S-2.1, r.4 and if the shoring jack can be used as an anchor point for a travel restraint system. The results of the study show 1) guardrails built on site with shoring jacks as supports, are safe and comply with S-2.1, r.4 and 2) shoring jacks used as supports for guardrails must not be used as an anchor for a travel restraint system.
