Which practice is NOT recommended when handling a corrosive?

• A. Use concentrated solutions whenever possible
• B. Wear PPE
• C. If exposed wash off skin immediately
• D. Carry bottles in secondary containers

Answer: (A)

Handling corrosive chemicals safely hinges on using the smallest amount that accomplishes the task, keeping spills contained, and protecting yourself with the right equipment. The practice that is not recommended is using concentrated solutions whenever possible because higher concentrations are far more likely to cause severe burns, release stronger fumes, and generate more heat if they contact skin, eyes, or come into contact with other substances. Working with the least concentrated solution needed reduces the risk of injury and makes any spill or splash less dangerous.

Wearing appropriate PPE—gloves, goggles or a face shield, lab coat, and sometimes a respirator or apron—provides a barrier against any contact with the chemical. If a spill or splash occurs, washing the exposed skin immediately with plenty of water helps remove the chemical and minimize damage. Carrying bottles in secondary containers is a good practice because it provides containment in case of leaks and makes transport safer, reducing the chance of spills and exposure.

In short, the safest approach is to use the smallest practical amount of a corrosive, protect yourself with proper PPE, and act quickly to decontaminate any exposure.
