To comply with good chemical hygiene, how should chemical labeling and storage be organized?

• A. Label all containers with identity and hazard; store compatible chemicals together; segregate incompatibles; use secondary containment; ensure ventilation and access control.
• B. Labeling is optional; store anywhere.
• C. Label only some containers; separate by color only.
• D. Keep all chemicals in open bins with no containment

Answer: (A)

Clear labeling and organized storage hinge on making risks visible and preventing dangerous interactions. Label every container with its chemical identity and hazard information so anyone handling it knows what it is and what risks it presents. Store compatible chemicals together to minimize unintended reactions, and segregate incompatibles (for example, acids from bases, oxidizers from organics, and flammables from reactive metals) to prevent dangerous combinations in spills or during transfers. Use secondary containment, such as trays or basins, to catch leaks and slow the spread of spills. Ensure adequate ventilation to control vapors and fumes, especially for volatile or toxic substances. Finally, restrict access to trained personnel to reduce mishandling and exposure. When these practices are followed, labeling and storage support safer handling and align with standard chemical hygiene expectations.
