Safety Helmets colour code guide

Maintaining the proper fit and style of PPE is important. Industrial plants and sites with a risk of injury or accidents are required to ensure the proper safety of people.

Safety helmets come in to protect our heads from any kind of fatal injury or accident while working in a danger-prone area. Various kinds, types of fits, and types of safety and PPE equipment are available in the market. But choosing the right one is important as it’s for the sake of work and death!


Safety helmets come in pre-defined colour codes for the uses based on the type of work and the site you are present at. These standard guidelines are made by some of the agencies, which are being followed by several organisations today. It makes it easier and more organised to know which helmet is suitable for the kind of work you are doing.

Below are the colour codes mandates for the safety helmets and their uses –

1. Yellow colour safety helmets

This colour code is for earth-moving operators, heavy-duty workers, and labourers working on construction sites.

2.Blue colour safety helmets

This colour is preferred by the electricians or technical workers like carpenters and interim workers.

3. Brown colour safety helmets

This is used by welders or people with high heat working areas

4. Green colour safety helmets

This shade is worn by the safety inspectors on-site, and some new trainees and officers also prefer green colour helmets.

5. White colour safety helmets

This is the basic colour that catches an eye amongst all the other colours. Hence, these colour helmets are used by supervisors, architects, engineers, and managers.

6. Red colour safety helmets

This colour is used by the firefighters and emergency trainees

7. Grey colour safety helmets

These are issued to site visitors on the worksite.

8. Pink safety helmets

These are preferred by female workers. In some companies, these are kept as an additional helmet.



Many companies and industries have kept the criteria of colour codes for safety helmets. No one will put you in jail or ask for a fine for not following them in the eye of the law and rule. Yet these colour codes are made for the benefit and safety of the people working on site.  There are various benefits of maintaining colour codes of safety helmets.



Colour codes help identify the employee’s position and give a clear idea of what task a person is attending. It helps a person in an emergency or query; colour sorts out who to look for.  Managers can also easily identify which group of workers is working on which site

Fast and smooth working process

Everyone following the colour code for safety helmets clearly understands which task they must perform. Also, there is a better differentiation for the co-workers to know which team is running which process. So it makes the work clear and smooth for working.

Although colour plays an important role, only looking for the colour is not enough. There are various key points to consider while you are buying a safety helmet.

Some of them are:

Quality check

The safety helmet should have a quality mark to ensure proper safety.  They are made of different materials. You should always check the quality of the helmet according to the task you have to perform on-site. As if you just look for the colour, it may still be wrong for you if the quality is not up to the mark. Therefore, looking for quality and material is always suggested before looking for the colour code.

Helmet shelf life

Just like most PPE PRODUCTS, safety helmets come with an expiry date as well. The material used in making the safety helmets deteriorates with time. Hence, the helmets should be timely replaced and maintained. Equally, the quality should never be compromised.
