RRC (Railroad Commission of Texas)

The prime contractor or site owner who directs work conditions and sets safety rules on a multi-employer worksite. As a subcontractor, you may still be cited for hazards even if the controlling employer created them. Knowing who holds this role determines your compliance obligations on any jobsite.

A regulatory approval authorizing a pipeline or facility to proceed to physical construction. Subcontractors cannot mobilise crews or begin ground disturbance until this permit is granted. Delays in approval directly impact project start dates and subcontractor scheduling.

A safety procedure requiring energy sources on equipment to be physically isolated and locked before maintenance work begins. Subcontractors must follow site-specific lockout procedures or risk removal from the worksite. Verify your crew holds valid lockout/tagout certification before mobilising.

A private dispute resolution process where a neutral third party settles contract disagreements outside of court. Subcontractors often encounter arbitration clauses in master service agreements. It can limit your right to sue a prime contractor or operator directly.

A federally mandated programme requiring safety-sensitive workers in transportation-regulated roles to undergo drug and alcohol testing. Subcontractors supplying drivers or operators must maintain a compliant testing programme or enrol through a consortium. Non-compliance can result in removed site access, contract termination, or regulatory penalties.

The company that directly exposes workers to a hazard on a multi-employer worksite, such as a subcontractor whose crew creates a fall risk. Under Canadian OHS regulations, the exposing employer holds primary responsibility for controlling that hazard. Subcontractors must understand this designation, as it determines who is liable for corrective action.
