Posted By naveen duggal Hi, wearing appropriate PPE in construction sites is cosidered as per dress code of conduct and client/contractor's agreement. Wearing yellow hi-viz jackets & coloured coveralls,Hard hat,safety shoes, safety glass, gloves, earplugs, dust masks..etc are the usual PPE acceptable. It is surprising to note that both Red coloured Hi-viz pants are to be worn at your site along with yellow coloured Hi-Viz jacket; a rare combination By the way, do you know when, where and why hi-viz jackets & trousers were introduced? As I recall, during the 2nd world war, the military, airfirce, Navy of many countries fought in Eroupe, due to cross-fire....many soldiers were killed or injured of same company in dark. In the Fire dept, Oil & Gas industry,in Sea, Red is the prominent colour,used to identify "Danger"And is also acceptable in transport, aviation,nuclear industry. So choice is yours!

Posted By Adrian Woon I too have never come across this one before. It could be the contractors "in - house" rules / requirements. However, I would like to learn the rationale for it.

Posted By Rodger Alan Ker A client or a Principal Contractor can place any requirements that they wish for a site. However the important criteria must be that they inform everyone of those requirements with appropriate warning (Tender State, pre-start meeting etc. It is poor planning and communication on their part if you have not been informed. However it is possible that your company has been informed of the requirements and that the Contract Manager has not cascaded the information downward.
