What must all bottles containing poisonous substances be designated with?

All bottles containing poisonous substances must have distinct labeling to clearly indicate the hazardous nature of the contents. This requirement serves as an important safety measure, ensuring that anyone who handles or comes into contact with these substances can immediately recognize them as dangerous. Distinct labeling typically includes specific information about the type of poison, instructions for safe handling, and emergency procedures in case of exposure.

While colored labels and warning symbols can be effective in signaling hazard, distinct labeling encompasses a broader requirement that includes clear and universally understood information. This ensures that there's no ambiguity regarding the contents of the bottle, enhancing safety in environments where esthetic procedures are conducted. In contrast, company logos do not provide essential hazard information and can be misleading or irrelevant to safety procedures.
