A credentialed professional who assesses and controls workplace health hazards such as chemical exposure, noise, and air quality. Subcontractors may be required to retain or consult a CIH to meet site entry or regulatory requirements. Their sign-off can be mandatory before work begins in confined spaces or hazardous environments.
CIH (Certified Industrial Hygienist)
Related Terms
Osha (occupational Safety and Health Administration) Recordable
ComplianceA work-related injury or illness that must be logged on an OSHA 300 form. This includes incidents requiring medical treatment beyond first aid, restricted work, or lost time. High recordable rates can disqualify subcontractors from bidding on major operator contracts.
S&S (Significant and Substantial)
ComplianceA regulatory classification used by MSHA to flag violations that could reasonably cause serious injury or illness. S&S citations carry higher fines and greater scrutiny for subcontractors working on mine sites. Accumulating S&S violations can jeopardise a subcontractor's site access and future contract eligibility.
Contractor Certification
ComplianceFormal verification that a subcontractor meets a client's safety, technical, or insurance standards before being awarded work. Most major operators require active certification through third-party registries such as ISNetworld or Avetta. Lapsed certification can result in immediate removal from approved vendor lists.
Trench Cave-in Protection
ComplianceMandatory safety systems used to prevent trench walls from collapsing on workers during excavation. Common methods include shoring, sloping, and trench boxes. Subcontractors are legally responsible for implementing compliant cave-in protection before workers enter any trench deeper than 1.2 metres.
Compliance Theatre
ComplianceWhen a prime contractor or client demands excessive paperwork and box-ticking that looks rigorous but adds no real safety value. Subcontractors absorb the administrative burden without reduced liability or improved site outcomes. Recognising it helps crews push back on busy-work that pulls focus from genuine hazard control.
Api 653
ComplianceAPI 653 (American Petroleum Institute Standard 653) governs the inspection, repair, alteration, and reconstruction of above-ground storage tanks. Subcontractors performing tank work must comply with this standard or risk failed inspections and contract penalties. Many operators require certified API 653 inspectors on-site before authorising any tank maintenance scope.
