Safety first

You are here:

Safety is at the forefront of everything we do.

Our absolute commitment to safety and the environment shows through management leadership and the positive behavioural safety culture demonstrated by our people, showing that safety is integral to everything that we do.
We have an excellent safety record and actively fund and promote a safety behavioural change programme with our colleagues and subcontractors which has made a significant contribution to the group’s safety culture. From the CEO to our colleagues on the front line, safety is everyone’s responsibility and is the key part of our commitment to the responsible development running through all our activities.
We are proud of our achievement and the safety behaviours shown by our colleagues. A continuous effort is put into maintaining this excellent safety performance, with a high emphasis placed on staff training, competence and assessment. We ensure our staff are offered training in all areas of safety compliance and work collaboratively with our supply chain to improve safety on all our sites.
We have actively funded and promoted a safety behavioural change programme since 2008, which has made a significant contribution to the group’s safety culture.

CARL Safety Reporting App









Our award winning, industry recognised workforce safety tool CARL, which stands for “Call, Action, Report, Learn” is a cross-platform mobile app promoting proactivity with safety in the business.

CARL is available internally for all Colas Rail Employees but it is also available for use by Third Party contractors.

The primary use for CARL is to provide all users with a simple and quick way to report Close Calls, which remain an important tool in improving health safety and wellbeing of staff, suppliers and members of the public.

Also part of CARL is our lifesaving rules, which provide a reminder of the rules which make up the basis for the leading company value, “Safety at the forefront of everything we do”.

In order to continuously improve our safety record, the quality of our working environment for our staff and enhance our performance for our customers, we formed a collaboration group between our internal Health & Safety and IT teams to develop an effective and convenient way of tracking and recording close calls to reduce safety incidents.

The CARL system has a simple and engaging app at its front end that allows anyone working with our business, to report a close call and record safety conversations. We have seen a direct link between an increase in safety conversations and a reduction in accidents.

CARL provides:
  • All users with a simple and quick way to report Close Calls
  • A reminder of the rules which make up the basis of our company values “Safety at the forefront of everything we do”
