Which safety equipment should be worn when handling fluoride chemicals?

When handling fluoride chemicals, it is critical to wear a respirator approved by NIOSH due to the potential for significant inhalation hazards. Fluoride compounds can release toxic fumes, especially in concentrated forms, which can cause respiratory issues. NIOSH-approved respirators are specifically designed to filter harmful particles and provide a proper seal around the face, ensuring that the individual is protected from inhaling any fluoride vapors or aerosols.

In addition to respiratory protection, it is also vital to use appropriate gloves and protective eyewear when working with fluoride to prevent skin and eye contact, as these chemicals can be corrosive and harmful upon exposure. However, the primary reason for selecting a NIOSH-approved respirator as the correct answer lies in the need for effective respiratory protection in environments where fluoride may be present in the air, making personal safety the top priority.
