CITB Tunnelling Safety Training Scheme (TSTS)

The CITB Tunnelling Safety Training Scheme (TSTS) is an essential course for anyone working in underground construction, ensuring workers and supervisors understand the unique hazards and safety protocols of tunnelling environments. Covering key topics such as confined spaces, ventilation, emergency procedures, and risk management, this CITB-accredited course provides the knowledge needed to maintain a safe and compliant worksite. Whether you are new to tunnelling or looking to enhance your expertise, the TSTS course equips you with industry-recognised training that meets the latest health and safety standards.

TSTS is a one-day awareness course covering the tunnelling environment itself, not site supervision, so anyone supervising underground normally holds SSSTS alongside it. Check the expiry printed on your own certificate, as the CITB scheme rules and some CITB course listings differ on the TSTS validation period.

International Recognition of the CITB TSTS Course

The CITB Tunnelling Safety Training Scheme (TSTS) course is widely respected in the UK and also recognised internationally in regions where UK tunnelling and construction safety standards are influential. As tunnelling projects often involve multinational teams, many employers in Europe, the Middle East (including the UAE, Qatar, and Saudi Arabia), and Asia value CITB qualifications for their practical, industry-focused approach. Recognition comes from the CITB’s reputation as the UK’s authority on construction training and safety standards, ensuring that learners gain transferable skills aligned with global best practice. This makes the TSTS course particularly valuable for professionals seeking to work on large-scale infrastructure projects both in the UK and abroad.
