What is control banding, and when is it used in chemical risk management?

• A. A quantitative model requiring precise exposure data.
• B. A qualitative approach that groups hazards into bands to recommend control measures when detailed exposure data are lacking.
• C. A training program for new hires.
• D. A financial risk assessment method.

Answer: (B)

Control banding is a qualitative approach to chemical risk management. It works by grouping hazards into bands based on the intrinsic hazards of the chemical and the potential exposure scenario, then recommending control measures appropriate to the band. It’s designed for situations where detailed exposure data or quantitative risk assessments aren’t available or practical, such as in smaller workplaces or with new or poorly characterized chemicals. By using simple band decisions rather than precise measurements, it helps establish sensible, risk-based controls (like enclosure, local exhaust ventilation, substitution, or work practices) without requiring extensive monitoring. It isn’t a training program, nor a financial risk method, and it isn’t a quantitative model that relies on exact exposure data.
