All people on construction site have responsibilities for safety, this includes all personal (employers, occupiers, contractors, workers) in the work-site area. The responsibility extends to those areas and activities over which the person has some control with construction site signs. If more than one person has a responsibility in relation to a certain area or activity, then all of those people must ensure that safety is maintained and not leave it to another person.
One of the most imortant methods to promote safety is by hanging posted signs. Construction site road signs announce to everyone the hazards found in the construction site, the safety measures to take while working or visiting the site, the ways to avoid accidents, the personal protection equipment required before entering the site and many other aspects related to construction and its hazards.
