According to respiratory protection regulations, what must the employer provide?

The correct answer highlights the comprehensive responsibilities an employer has regarding respiratory protection regulations. Employers are mandated to ensure that their employees are adequately prepared to use respiratory protection effectively and safely. This includes providing medical evaluations to determine if an employee can safely wear a respirator, fit testing to ensure that the respirator creates a proper seal and functions as intended, and training to educate employees on how to use, maintain, and care for their respirators.

By fulfilling these requirements, employers help ensure that workers are not only protected from respiratory hazards but also competent in the use of the equipment, ultimately leading to a safer workplace environment. Without these crucial components, the effectiveness of respiratory protection could be compromised, exposing employees to potential health risks.
