Which practice must be avoided in handling chemicals?

• A. Wear goggles, face shield, rubber gloves, gum boots and aprons while handling against splashing.
• B. Treat all liquids as dangerous, until you know that they are safe.
• C. Handle very carefully the bottles/containers which have no labels.
• D. Carry acid in an open container.

Answer: (D)

Handling chemicals safely hinges on preventing exposure and containment failures. Carrying acid in an open container must be avoided because acids are corrosive and a lidless container invites spills, splashes, and the release of hazardous fumes. This creates immediate burn and eye injury risks and can spread contamination quickly, making it hard to control the situation. Use properly closed, labeled containers and appropriate containment when moving acids. The other practices support safety: wearing the right PPE protects you from splashes; treating every liquid as potentially dangerous follows a precautionary approach; and if a container is unlabeled, it should not be handled until its contents are identified and properly labeled.
