Final answer:
Earplugs do not generally require an MSDS as they do not contain chemicals that pose a hazard. Employers must provide a safe work environment and inform workers about chemical hazards, adhering to OHSA and OSHA standards.
Step-by-step explanation:
An occupational health nurse assessing the need for Material Safety Data Sheets (MSDSs) at a worksite would be looking for items that pose potential chemical hazards to workers. Earplugs typically do not require an MSDS as they are considered personal protective equipment (PPE) without inherent chemical risks.
However, it is crucial that workplaces follow the Occupational Safety and Health Act (OHSA) and the standards set by the Occupational Safety and Health Administration (OSHA), which emphasize the importance of providing a safe working environment. Employers are mandated to minimize hazards through engineering and administrative controls before resorting to PPE. They also have the responsibility to inform workers about chemical hazards, provide safety training, offer medical tests, and supply necessary PPE at no cost to the workers. While earplugs do not necessitate an MSDS, ensuring their proper use and the workers' awareness of the potential risks in a noisy environment is a part of the employer's duty.
