An OSH audit is a systematic examination of an organization's health and safety activities and results to determine if they conform to planned arrangements. Audits evaluate an entire company's health and safety system and controls, while inspections identify issues in a workplace for corrective action. Investigations inquire into accidents to discover their root causes. Audits can be first, second, or third party. They must have clear objectives and criteria, be objective and thorough, and result in a written report documenting any nonconformities and the audit findings. The audit report should be clear, precise, complete, dated, and signed by the auditor. It includes details like the audit objectives, plan, team, dates, areas audited, standards used
