What OSHA form serves as the annual summary of a company's injuries and illnesses?

The annual summary of a company's injuries and illnesses is reported on Form 300A. This form is crucial as it aggregates the data collected on a company's Form 300, where individual incidents are recorded throughout the year. The Form 300A provides a clear summary, which includes the total number of work-related injuries and illnesses, and it is required to be posted in the workplace for employees to review. It helps in tracking safety performance and is an essential tool for compliance with OSHA reporting requirements.

Form 301 is used for reporting individual incidents and detailing the nature of each injury or illness, while Form 300 is the log of all work-related injuries and illnesses. Form 302 is not standard or relevant in this context, as it is not part of the OSHA recordkeeping forms commonly used. Therefore, the role of Form 300A as the annual summary makes it the correct choice for this question.
