What is the purpose of control banding in IH?

• A. To categorize hazards based on hazard potential and exposure scenarios when detailed quantitative data are limited, guiding controls
• B. To measure exposure levels
• C. To replace engineering controls with PPE
• D. To determine chemical disposal methods

Answer: (A)

Control banding is a qualitative risk-management approach used when detailed quantitative exposure data aren’t available. It groups hazards by how toxic they are and considers typical exposure scenarios to place them into exposure bands, then links those bands to practical control strategies. The aim is to provide practical, conservative guidance for selecting controls without needing complex exposure calculations, which is especially helpful for small workplaces or new chemicals.

This approach best fits the question because it focuses on guiding what controls are needed under data-poor conditions, rather than measuring exact exposure levels, replacing engineering controls with PPE, or determining disposal methods.
