The head protection features the same high-intensity reflective material used on motorway signs.
The Evolite CR2 range features the strips all over its hard hats to maximise visibility on dark construction, civil engineering, road and rail sites
The helmets come in a full range of colours and each colour can be used to denote a different type of site task.
Green usually denotes a first-aider, while orange normally indicates a banksman.
Blue is commonly used for site managers or contract agents, and red for fire marshals.
The system allows the standardisation of helmet colour so plain white helmets could be used for all workers, with the addition of different-coloured reflective strips to denote different job titles.
Simon Apsey, Business Development Manager at JSP, said: “It’s amazing that such a simple, inexpensive, idea can make such a difference.
“It is normally the head that gets in harm’s way first, so it needs to be illuminated.
“By putting coloured, highly- reflective, strips all round the helmet, JSP is making workers on our highways and construction sites visible in all conditions.
“The response from customers has been extremely positive, and many leading contractors have already adopted the system as standard.”
