Question

identifying safety protocol for the lab experiment
which statements are part of the safety protocol for this lab experiment? check all that apply.
wear a lab coat and safety goggles when performing an experiment.
always measure chemical quantities twice before adding to solution.
use caution when connecting electric circuits.
do not drop the magnets.
do not use electrical currents.
do not bring bar magnets near magnetic devices.
always disconnect circuits when not in use.

Explanation:

• Wearing a lab coat and safety goggles protects from chemical splashes and physical hazards.
• Using caution when connecting electric circuits prevents electrical shocks.
• Not dropping magnets avoids damage to magnets and potential injury.
• Not bringing bar magnets near magnetic devices prevents interference and damage.
• Disconnecting circuits when not in use reduces electrical risks.
• Measuring chemical quantities twice is a measurement - accuracy step, not a safety protocol.
• Not using electrical currents is too extreme as many experiments require them (if done safely).

Answer:

Wear a lab coat and safety goggles when performing an experiment, Use caution when connecting electric circuits, Do not drop the magnets, Do not bring bar magnets near magnetic devices, Always disconnect circuits when not in use.
