A work-related injury or illness that meets specific criteria requiring formal logging under OSHA regulations, including cases involving days away from work, restricted duties, medical treatment beyond first aid, or loss of consciousness — a metric that directly affects a subcontractor's safety record and can impact their eligibility for future contracts with operators and prime contractors.

Review ownership clauses carefully before signing to protect your company's records and liability position.
