Tongs are likely to be used to pick up and hold items ranging from sugar lumps, small lumps of coal (non dangerous); contaminated or toxic material, test-tubes over a bunsen-burner's flame (possibly dangerous). If possibly dangerous, wear safety glasses, gloves and an apron.

Tongs
Test tube tongs are used to safely handle hot test tubes and beakers in the laboratory. They provide a secure grip and prevent accidental burns or spills. Test tube tongs are typically made of metal with insulated handles for heat protection.
Test tube tongs are specialized tools used in laboratories to safely hold and manipulate test tubes. They typically have rubber or plastic coated tips to provide a secure grip without damaging the glass. Test tube tongs help prevent accidents and protect the user from chemicals or heat during experiments.
Because sometimes in a lab,you use different and dangerous type chemicals so if for example,You pour a very chemical that uyou can't touch the test-tube and then you have to use the Tongs just so that you could be safe so I think that it is safe and the best idea to have tongs kept near the top of the test-tubes
Skidding tongs are used to grip and lift logs for skidding or dragging purposes. To use them, attach the tongs securely to the log using a chain or cable. Make sure the tongs are firmly clamped onto the log before attempting to lift or move it using a skidder or winch.
A test tube holder is a laboratory tool used to hold test tubes securely while heating them over a Bunsen burner or other heat source. It is designed with insulated handles to safely grip hot test tubes and prevent burns or accidents. Test tube holders allow for efficient and controlled heating of the contents inside the test tube.
A boiling tube is for boiling chemicals or metals, a test-tube is for holding chemical reactants. Test tubes are slimmer, boiling tubes are wide and are made of thin glass

A test tube holder or flask tongs are commonly used in laboratories to safely hold test tubes or flasks during experiments. They have two long arms hinged together, providing a secure grip and keeping the user at a safe distance from chemicals or heat.
A test tube holder is used to hold and carry individual test tubes securely, typically made of metal or plastic with a spring mechanism to grip the tube. A test tube rack is used to hold multiple test tubes upright and organized, often made of plastic or wood with holes to fit the test tubes.
