What does OSHA mandate regarding first aid supplies on the job site?

The correct choice emphasizes that OSHA mandates first aid supplies must be readily available and made accessible on the job site. This requirement is essential to ensure that in the event of an injury or medical emergency, prompt assistance can be provided. Quick access to first aid supplies can significantly affect the outcome of a workplace injury, fostering a safer and more responsive work environment.

The focus on being "readily available" means that employers are responsible for ensuring that first aid kits are not only stocked but easy to reach when necessary, thereby mitigating potential delays in response to injuries. This requirement underscores the importance of preparedness in workplace safety protocols. The regulation does not specify a particular frequency for restocking, nor does it require specialized equipment or mandate that supplies be stored in a locked cabinet, as those aspects can vary based on the specific needs of the workplace and the nature of the jobs being performed.
