While we are extremely proud of the work that we do here at NatraTrex and amazed at the ingenuity of our clients, it’s important we recognise the health and safety requirements of our industry. Bitumen products can be dangerous if mishandled — but only if they’re still in their hot liquid state.

Why Is Bitumen Sometimes Dangerous?

It’s important to emphasize that bitumen products are only dangerous when they’re hot and still curing. This is because of two reasons:

  • As they cure, bitumen products release fumes
  • The process involved in their creation

How Bitumen Products Are Made

Whether naturally occurring or derived from petroleum, bitumen is a hydrocarbon very similar to crude oil. In its simplest form, it has a consistency similar to crude oil, with a similar rate of impurities. In order to turn it into something useful, the petroleum-like bitumen compound is purified and then mixed with industrial solvents.

In its liquid state, this new material is extremely flammable. If breathed in, its fumes can cause coughing, a scratchy throat, headaches, skin rashes, eye irritation and lung problems. Ultimately, breathing in this material can lead to long-term damage.


Because of these risks, the ideal environment for bitumen application is one with a lot of ventilation. Bituminous materials should only be laid by well-trained and experienced professionals. Anyone laying hot bituminous material should be wearing the proper health and safety equipment — which can involve a breathing mask depending on where the work is being done.

One way of avoiding the majority of health and safety risks of bituminous materials is to use one that can be laid cold — such as our Coldlay product — as the basis of your surfacing. Cold lay products cure like other bituminous products. However, they do so without heat. This means that they don’t release fumes in the same way as traditional bituminous products do — they only start to cure once they have been compacted. This means a much lower risk for the people laying the material.

NatraTex ColdLay is particularly ideal for repairs to small areas. All you need to do to use it is simply empty the contents of the bucket onto the area to be reinstated and hand compact to start the curing process. It is that simple!

Is Bitumen Dangerous?

Ultimately, while no industrial product is not without its health and safety risks, as long as the proper health and safety precautions are being followed, bitumen products are perfectly safe.
