Which of the following events qualifies an injury to meet OSHA 29 CFR 1904 recording requirements?

An injury qualifies under OSHA 29 CFR 1904 recording requirements when it results in a loss of consciousness. This is significant because losing consciousness indicates a more serious level of impairment and can reflect potential hazards within the workplace environment. Such an incident is critical for recording purposes as it helps in monitoring and assessing workplace safety and can prompt investigations into the causes and prevention measures.

The other options, while they may involve injuries, do not meet the specific criteria set by OSHA for recording. Minor first aid treatment or injuries that require only self-care typically do not necessitate official recording as they are not considered significant enough to impact the overall safety assessment. An injury deemed significant by a physician may be recorded, but it is the loss of consciousness that creates an immediate and clear requirement for reporting under OSHA regulations.
