Which of the following can you store on open shelves in the laboratory?

Storing buffers, sugars, and some salts on open shelves in the laboratory is considered appropriate because these substances are generally non-hazardous or low-risk in nature. They do not pose significant threats to safety, like chemical spills, fires, or biological hazards, making them suitable for open shelving in a lab environment. This allows for easier access and organization, as well as efficient use of storage space.

In contrast, hazardous chemicals and acids can pose serious health and safety risks if spilled or improperly handled, necessitating secure storage solutions to prevent accidents. Similarly, volatile solvents and flammable materials require specific storage conditions to mitigate the risk of fire or explosion, often stored in flame-proof cabinets or ventilated areas. Medical waste and biological samples must adhere to strict disposal and containment protocols to limit exposure to potentially infectious materials and ensure compliance with health regulations, thus requiring secure and dedicated storage options away from general lab areas.
