Which will ensure laboratory safety during the experiment? Check all that apply.

Use beaker tongs to handle a hot beaker to prevent burns. Check the beaker for chips before heating, since damaged glassware can break when heated, and turn off the hot plate after use to reduce fire and burn risks. Reading the thermometer accurately is important for getting reliable results, but it is not itself a laboratory safety measure; choosing a beaker over an Erlenmeyer flask does not ensure safety.
