Which of the following is a primary hazard when handling foam glass?

• A. Heavy metal exposure
• B. Noise-induced hearing loss
• C. Irritation to the eyes and skin
• D. Magnetic interference

Answer: (C)

Foam glass handling mainly risks irritation to the eyes and skin from fine glass dust. When the material is cut, ground, or handled, it can release tiny particles that can scratch and irritate the eyes and mucous membranes, and cause skin redness or itching on contact. Because of this, the primary safety focus is on eye protection, skin protection, and dust control—safety glasses or a face shield, gloves, and a dust mask, plus methods to minimize dust (like damp cutting and good ventilation).

Heavy metal exposure, noise-induced hearing loss, and magnetic interference are not the primary hazards for this material in typical handling. Metals or loud tools could pose separate risks in specific contexts, but the dominant risk with foam glass is dust irritation to eyes and skin.
