Construction Pocket Guide

Quiz Questions:
   
1. Which one of the following could be potential hazard to construction workers.
       
    Falls (from heights)
    Trench collapse
    Scaffold collapse
    Electric shock and arc flash/blast
    Failure to use proper personal protective equipment; and
    Repetitive motion injuries
    All of the above
       
2. Which one of the following could help in fall protection.
       
    Using aerial lifts or elevated platforms to provide safer elevated working surfaces.
    Erect guardrails systems with toeboards and warning lines or install control line systems to protect workers near the edge of floors and roofs
    Cover floor holes
    Use safety net systems (body harnesses)
    All of the above
       
3. The following could help to avoid trench collapses.
  • Never enter an unprotected trench
  • Always use a protective system for trench 5 feet deep or greater.
  • Employ a registered professional engineer to design a protective system for trenches 20 feet deep or greater.
  • Protective systems:
  • Sloping to protect workers by cutting back the trench wall at an angle inclind away from the excavation not steeper than a height/depth ratio of 1 ½ : 1, according to the sloping requirements for the type of soil.
  • Shoring to protect workers by installing supports to prevent soil movement for trenches that do not exceed 20 feet in depth.
  • Shielding to protect workers by using trench boxes or other types of supports to prevent soil cave-ins.
  • Always provide a way to exit a trench-such as a ladder, stairway or ramp-no more than 25 feet of lateral travel for employees in trench.
  • Keep spoils at least two feet back from the edge of a trench.
  • Make sure that trenches are inspected by a competent person prior to entry and after hazard-increasing event such as rain storm, vibrations or excessive surcharge loads.
