The OSHA 300 log includes which injuries or illnesses?

• A. Only minor injuries
• B. All injuries requiring medical attention
• C. Injuries resulting in lost workdays, restricted work or transfer, and any incident requiring more than first-aid treatment
• D. Only illnesses diagnosed by a physician

Answer: (C)

The task tests understanding of what types of cases OSHA requires to be recorded on the 300 log. The log is meant for work-related injuries and illnesses that have real consequences beyond simple care, so it focuses on cases that affect a worker’s ability to continue working. A case is recordable when it results in days away from work, restricted work or a job transfer, or medical treatment beyond first aid. That means injuries or illnesses that only need basic first aid aren’t put on the log, while those that cause time off, changes in duties, or more extensive medical care are. The option describing lost workdays, restricted work or transfer, and any incident needing more than first-aid treatment matches these criteria, which is why it’s the best choice. It’s not appropriate to say the log includes all injuries requiring any medical attention, or only illnesses diagnosed by a physician, because those ideas are too broad or rely on specifics (like a physician diagnosis) that don’t determine recordability on their own.
