Answer 1

The statement that is NOT a proper safety procedure for scientific experiments is:

"Only perform experiments that can be done in open air laboratories."

While some experiments need to be performed in well-ventilated areas or open air, not all experiments can or should be limited to open air laboratories; many can be conducted safely in controlled environments with proper precautions. The other options listed are important safety procedures.
