When safety violations are deemed willful, meaning the employer or a supervisory employee intentionally disregarded or was plainly indifferent to safety regulations, the consequences can be severe. Superintendents and crew leaders, as supervisory personnel with responsibility for job site safety, can be held financially and criminally liable (D) for such violations, in addition to potential penalties for the company itself. Negligent workers (A) may face disciplinary actions but are not typically fined by regulatory bodies. Upper management (B) can also be held liable, and employers are indeed liable for employee injuries or deaths resulting from safety violations (C). (OSHA Act of 1970; Fundamentals of Crew Leadership, Fourth Edition, NCCER, Section 3.3.2 Consequences of Violations)
