to avoid contaminating the chemical when the stopper is replaced
Corrosive
My opinion on this question, is that gases may come off the bottle, maybe even liquids, if the bottle is frozen enough, solids may drop off it as well.
a safety mat or is also known as the bench mat

"Bench science" as answered by my biostatistician professor refers to science that is exclusively conducted in a lab setting, closely related to "wet science" or "hands on research." The opposite of the bench Scientists who conduct research in the laboratory setting are the statisticians who will analyze gathered data and draw conclusion from the findings. Think Bench Science, think looking under a microscope.
Placing bottle stoppers upside down on the science bench helps prevent contaminating the inside of the stopper with bench surface germs. This practice ensures a cleaner seal when using the stopper in a solution to prevent contamination of the contents.
Placing bottle stoppers upside down on the bench helps prevent dust and debris from settling on the part that will come in contact with the bottle opening, ensuring better hygiene when reusing the stopper. It also allows for any lingering moisture to drain out and air to circulate, reducing the chances of mold or mildew growth inside the stopper.
The stopper of a chemical reagent container should be handled carefully for two reasons. Firstly, it may contain chemical residues which can be dangerous. Additionally, if the stopper is dirtied it may contaminate the reagent in the bottle when the stopper is put back on.

Corrosive
The hazchem symbol for a bottle of bench acid would be "C" for corrosive. This symbol signifies that the substance is corrosive and can cause burns or damage to skin, eyes, and surfaces it comes into contact with.
When a cold water bottle is placed on a warmer surface, such as a bench, the air around the bottle cools down and cannot hold as much moisture, causing condensation to form on the outside of the bottle. This moisture then transfers to the bench, leaving a ring of moisture.
you should bench your weight or more
Warren is in Radopolis, his bottle is beside a bench.
If chemicals spill on the work bench, immediately absorb the spill with appropriate absorbent materials. For spills on the side of a reagent bottle, clean it with a damp cloth to prevent contamination and ensure proper labeling. It's important to follow the specific safety protocols outlined in your lab's chemical hygiene plan.
you should be able to bench your own weight.
The symbol on a bottle of bench acid is typically a corrosive hazard symbol. This symbol is internationally recognized and consists of a black symbol on a white background with a red diamond and border. It is used to indicate that the substance inside is corrosive and can cause skin burns or eye damage.
