A beaker about two-thirds full of liquid: wear chemical resistant gloves and use a proper pouring tool, but do not taste.

A hot plate: use tongs to remove hot items, do not touch the surface, and turn it off after use.

A Bunsen burner: clear the lab table, tie back long hair, and turn it off after use.

Use tongs to remove hot items.

Do not touch the surface. It may still be hot even after use and can cause burns.

Turn off after use.
