True or False: A respirator does not need to be worn when adding sulfuric acid chromate solution to prevent scaling in a cooling tower.

True or False: A respirator does not need to be worn when adding sulfuric acid chromate solution to prevent scaling in a cooling tower.

• A. False
• B. True
• C. Not applicable
• D. Unsure

Answer: (B)

When handling acid-based cooling tower treatments, the need for a respirator depends on inhalation exposure. If the sulfuric acid chromate solution is added through a properly calibrated dosing system into a well-ventilated or closed system, the amount of airborne acid is typically very low, so a respirator is not required for routine addition. The emphasis is on minimizing exposure through engineering controls and proper handling: use eye protection, chemical-resistant gloves, and a splash shield or face shield as needed, and follow the safety data sheet. If ventilation is inadequate, or there’s a risk of splashing or aerosol formation, then respiratory protection would be necessary.
