An occupational injury and illness log must be kept at every job site for businesses with more than how many employees?

The requirement to keep an occupational injury and illness log is tied to the regulations set forth by the Occupational Safety and Health Administration (OSHA). For businesses that have 10 or more employees, it is mandated to maintain these logs at their job sites. This is crucial not only for tracking workplace injuries and illnesses but also for ensuring that employers comply with safety regulations and can respond appropriately to any safety issues that may arise.

Businesses with fewer than 10 employees are typically exempt from this requirement, as they may have less frequent occurrences of injury and illness data to track. However, once the employee count reaches 10, the obligation to document and maintain this log comes into effect, allowing for better oversight and enhancement of workplace safety protocols.

Thus, the correct answer reflects the legal threshold for maintaining these important records and underscores the significance of occupational safety management in relation to workforce size.
