What hazard must be considered when using N-95 respirators in the workplace?

When considering the use of N-95 respirators in the workplace, it's crucial to recognize that they are designed to filter out non-oil-based particulates. However, they are not rated for oil mists, which is why non-resistance to oil mists is a significant concern.

N-95 respirators effectively filter at least 95% of airborne particles, but their performance diminishes in the presence of oil aerosols. This limitation is important to acknowledge, especially in environments where oil mists from processes such as machining, painting, or other industrial applications may be present. The failure to address this aspect could lead to exposure to harmful particulates that the respirator is not equipped to handle.

In contrast, the other hazards presented—flammability of materials, resistance to chemical vapors, and overall weight of the respirator—are not the primary concerns related to the specific function of the N-95 respirator in most workplace scenarios. Understanding these limitations is essential for ensuring proper respiratory protection and maintaining workplace safety.
