When must the summary of work-related injuries or illnesses be posted in the workplace?

The correct answer is February 1st to April 30th. This timeframe aligns with the Occupational Safety and Health Administration (OSHA) requirements regarding the posting of the summary of work-related injuries and illnesses, specifically, the OSHA Form 300A. Employers are mandated to post this summary in a visible location in the workplace each year during this period. This posting allows employees and visitors to understand the organization's safety record and the types of injuries or illnesses that have occurred in the previous calendar year.

This requirement is significant as it promotes transparency about workplace safety and injury reporting, helping to foster a culture of safety within the workplace. It is vital for compliance with OSHA regulations and serves as an important educational tool for employees regarding their own health and safety.
