Health and safety on your construction site is expected to be a top priority with legal requirement in place to enforce it.  Its a challenging exercise but with a legal and moreal responsibility its an essential task for any employer.

Site safety signage plays a vital role in communicating safety information regardless of native language which will in turn reduce or eliminate the risks posed to employees, visitors, sub-contractors and the general public. The main aim of the system of safety signs is to draw attention immediately to objects and situations capable of causing hazards. The Guide to Safety, Health and Welfare at Work (General Application) Regulations 2007 advise; where there is a risk at a workplace because of traffic movements or traffic and pedestrian interaction, appropriate signs regulating traffic and pedestrian movements should be put in place in accordance with any other legislation specifically regulating transport by road, water, rail or air. Regulation 161 states that all employees must be provided with information and instruction on measures to be taken and on the meaning of safety signs and signals used. Schedule 9 recommends some general requirements
