What is one key requirement of OSHA regulations regarding chemical exposure?

One key requirement of OSHA regulations regarding chemical exposure is that employers must provide reasonable access to medical records. This is crucial because it ensures that employees have the right to be informed about their exposure to hazardous substances and can make informed decisions regarding their health and safety. By having access to medical records, employees can understand the potential risks associated with their work environment and seek out necessary medical attention if needed. This transparency is a fundamental aspect of employee rights under OSHA, promoting a safer workplace through informed choices.

The other options do not align with OSHA requirements. Casual clothing does not pertain to safety standards, and simply allowing employees to choose whether to wear personal protective equipment (PPE) undermines the responsibility of both the employer and the employees to maintain a safe working environment. Moreover, employers have a duty to provide PPE to ensure that workers are protected from hazards, not absolve themselves of this responsibility.
