We have all been at a construction site—either as workers, supervisors visitors, or even as project owners. The sights and sounds are familiar: the clanging of metal, the buzz of machinery, and the sharp whistles from site supervisors cutting through the dusty air.
But if you look closely, you’ll notice one subtle yet intriguing detail—the helmets.
From bright yellow to deep blue, these helmets serve a purpose beyond just head protection. But what do these colours really mean?
The silent code of safety helmets
Walk into any well-organised construction site in Kenya, and you'll likely notice that workers aren’t just wearing random helmet colours.
There's a clear colour code, an international standard followed in many parts of the world, even though some Kenyans don’t follow it:
White helmets
Worn by engineers, architects, site managers, and supervisors. These are the decision-makers, the ones responsible for ensuring everything is done to specification.
If you see someone in a white helmet staring at blueprints, they’re likely the brains behind the project.

Yellow helmets
The most common. These belong to general labourers and skilled workers on site.
If you spot a sea of yellow helmets, you’re probably looking at the hands that bring architectural dreams to life.
Blue helmets
Reserved for electricians, plumbers and other technical workers. A person in a blue helmet is likely dealing with wiring, fixing circuits, or ensuring your building doesn’t end up with water leaks.

Green helmets
Worn by safety officers. These are the people ensuring that everyone follows protocols, wears protective gear, and avoids unnecessary accidents. If something goes wrong, they’re the first to step in.
Red helmets
Firefighters and emergency rescue teams. If you see someone in a red helmet, know that they’re trained to handle emergencies.
Grey helmets
There are for either site visitors or interns in the site. They are also sometimes worn by those in welding and fabrication.

Pink helmets
Often designated for road crews or temporary people on site for example food vendors.
Despite the obvious benefits of colour-coded helmets, Kenya’s construction laws remain silent on the matter.
According to industry experts, this is largely because helmet colours have always been enforced through company policies rather than government legislation.
The importance of helmet colours in construction
At first glance, one might think helmet colours are just a formality. But in a crisis, they can be the difference between order and chaos.
Imagine an emergency situation where responders need to find the safety officer—wouldn’t it be easier to spot someone in a green helmet than trying to ask around?
Even for workers, knowing who to approach for specific issues can make tasks more efficient. If a labourer needs guidance on a structural detail, they know to look for a white helmet.
