Question

Check all appropriate safety precautions for handling each of the three items shown.

A beaker about two-thirds full of a liquid.
Check all that apply.

Pour using tongs.

Wear chemical resistant gloves.

Taste to make sure it is HCl.
A hot plate, with a knob on the front for setting temperature.A bunsen burner, with a flame visible.

Answer 1

For the beaker (liquid)
- Wear chemical-resistant gloves — Yes (when handling unknown or corrosive/irritating chemicals).
- Pour using tongs — No (tongs are for hot objects; use proper glassware handling, a support/holder, or a funnel; use tongs only if the beaker is hot).
- Taste to make sure it is HCl — Never. Do not taste chemicals to identify them.

Additional safe practices: wear safety goggles and a lab coat, work in a fume hood if vapors are possible, label containers, and pour carefully (use a glass stirring rod/funnel to control flow if needed).

For the hot plate
- Use heat-resistant gloves or tongs when handling hot glassware — Yes.
- Keep flammable liquids away and do not use a hot plate to heat volatile/flammable solvents unless the hot plate is rated for that use and proper controls are in place — Yes.
- Place on a heatproof surface, do not leave unattended while heating, turn it off and allow to cool before touching, and use appropriate glassware rated for heating.

For the Bunsen burner (open flame)
- Tie back long hair, secure loose clothing, wear goggles and a lab coat — Yes.
- Keep flammable materials and volatile solvents well away — Yes.
- Light with a striker (follow proper lighting procedure), never leave an open flame unattended, and use heatproof mats/tongs/gloves for hot objects — Yes.
- Do not use an open flame to test/identify chemicals (never taste or sniff).

If you want, tell me the specific choices shown for the hot plate and burner and I’ll mark which apply.
