Overview
Chemicals are not stored in a safe and proper manner, for example, not segregated by compatibility, unnecessary cylinders stored within the lab, flammable liquids stored outside of rated cabinets, flammable liquids stored in regular fridge or freezer, spill scenario of > 20 L, etc.), specialized storage recommendations by supplier, and for those with unique hazards, other considerations
This checklist item is relatively self-explanatory. However, based on past experience in reviewing audit reports we need to emphasize that this should not be taken too far, for example, citing a lack of a shelf lip, storage above eye level, secondary containment (unless necessary for segregation to ensure compatibility or limit spill scenario to less than 20L), storage under a sink unless there is a reason (for example, storage of corrosives that will damage the plumbing, water reactive materials under a sink, etc.).
