Name two common hazard controls for chemical hazards.

• A. Adequate ventilation
• B. Proper storage/segregation of incompatible chemicals
• C. Both Adequate ventilation and proper storage/segregation of incompatible chemicals
• D. PPE only

Answer: (C)

Two common controls for chemical hazards are adequate ventilation and proper storage/segregation of incompatible chemicals. Adequate ventilation reduces the amount of airborne contaminants workers inhale by diluting and removing vapors and fumes from the work area, which cuts down acute and long-term health risks. Proper storage and segregation prevent dangerous chemical interactions, spills, and cross-contamination by keeping reactive substances apart and stored under appropriate conditions, which lowers the chance of fires, releases, or unexpected reactions.

Together, these controls address both exposure and chemical reactivity, offering broad protection in many settings. PPE alone isn’t as protective because it only shields individuals without reducing the hazard at its source, and using ventilation or storage alone misses other risk aspects.
