Which of the following injuries must be reported to DOSH?

• A. A concussion causing absence from work for a full day
• B. A minor cut treated with a Band-Aid
• C. A small bruise with no time off
• D. A mild headache after work

Answer: (A)

The key idea is that DOSH reporting is triggered by work-related injuries that are serious enough to affect the employee, such as requiring time away from work or more than first-aid medical treatment. A concussion that causes the employee to be absent for a full day demonstrates a significant work-related impact and typically must be reported to DOSH within the required timeframe. The other options are considered minor or treated with basic first aid and do not meet the threshold for reporting: a small cut treated with a Band-Aid is first aid, a small bruise with no time off isn’t reportable, and a mild headache after work isn’t a recognized reportable work-related injury. In practice, always follow Cal/OSHA rules for reportable incidents, which include fatalities, inpatient hospitalizations, amputations, and loss of an eye, with the understanding that injuries causing time off are treated as reportable in many training contexts.
