TRC (Texas Railroad Commission)

A mandatory work stoppage called by a prime contractor or owner to address an immediate safety concern or incident. All field personnel halt operations and gather for a safety review before work resumes. Subcontractors must comply immediately, regardless of schedule or milestone pressures.

A work-related injury or illness that requires more than basic first aid, such as medical treatment, restricted duty, or lost time. Subcontractors must log these incidents and report them to the prime contractor. High recordable rates can disqualify your company from future bids or vendor pre-qualification lists.

Personal protective equipment embedded with sensors that monitor worker vitals, location, and environmental hazards in real time. Data is transmitted to site supervisors, enabling faster emergency response. Subcontractors may be required to supply or wear client-specified Smart PPE as part of site access agreements.

A provision in occupational health and safety legislation requiring employers to protect workers from recognised hazards, even when no specific regulation exists. For subcontractors, this means you can be cited for unsafe conditions on site regardless of client-controlled environments. It applies to your workers whether you own the worksite or not.

Any part that contains or holds pressurised fluid, such as a valve, fitting, or vessel wall. Subcontractors handling these parts must meet strict inspection and certification requirements. Improper installation or repair can trigger liability, stop-work orders, or regulatory penalties.

A single compliance document covering multiple jobs or site visits within a set period, rather than issuing one per mobilisation. Common for insurance, tax exemption, or safety credentials. Reduces paperwork for subcontractors working repeat engagements with the same operator.
