How many basic types of injury and illness records must be maintained by each establishment under OSHA?

The correct choice reflects the requirement set by OSHA regarding the maintenance of injury and illness records. Under OSHA regulations, specifically 29 CFR Part 1904, employers are mandated to maintain records of work-related injuries and illnesses if they have 11 or more employees. However, establishments with 15 or more employees are subject to the requirement to maintain the OSHA 300 Log and other related records.

This requirement ensures that workplaces track relevant health and safety statistics, allowing for better understanding and implementation of safety measures. Maintaining these records helps organizations identify patterns of incidents and make informed decisions to improve workplace safety, ultimately reducing the risk of future injuries and illnesses.

The other choices do not accurately reflect the threshold established by OSHA for maintaining such records, which specifically indicates that employers with 15 or more employees must comply with these record-keeping requirements.
