What must employers provide according to OSHA lead regulations?

Employers are required by OSHA lead regulations to provide appropriate respirators for tasks where employees may be exposed to airborne lead. This is crucial because lead exposure can pose significant health risks, including respiratory issues and other serious illnesses. The type of respirator provided must be suitable for the level of lead exposure workers may encounter and should effectively filter out lead particles. Ensuring that workers have the necessary respiratory protection is part of an employer's responsibility to maintain a safe working environment in compliance with OSHA standards.

The other options, while they may represent supportive or beneficial workplace practices, do not address the specific regulatory requirements set forth by OSHA regarding lead exposure and worker safety. Thus, they do not align with the key focus of lead safety regulations.
