 What is difference between qualified and competent?
 
 A competent person
 
 must be able to identify hazards within the construction jobsite
 
 and solve those issues or take action to stop the work until the issues can be resolved. A qualified person has the knowledge to design and supervise the installation of the protective fall protection systems to be used on that jobsite.
 What type of material is never appropriate to use as a hole cover?
