Question

personal eyeglasses provide as much protection as
a face shield
safety glasses
splashproof chemical goggles
none of the above
long hair in the laboratory must be
cut short
held away from the experiment with one hand
always neatly groomed
tied back and kept away with hairband, pins, etc.
in a laboratory, the following should not be worn
loose clothing
dangling jewelry
sandals
all of the above

Explanation:

1. Personal eyeglasses are not designed for laboratory safety; they lack the impact resistance, side protection, or chemical splash protection of dedicated safety gear like face shields, safety glasses, or chemical goggles.
2. In a lab, long hair poses a fire or contamination risk, so it must be secured fully away from experiments using hair restraints.
3. Loose clothing, dangling jewelry, and sandals all create hazards in a lab (catching fire, getting caught in equipment, or exposing skin to hazards), so none should be worn.

Answer:

1. none of the above
2. tied back and kept away with hairband, pins, etc.
3. all of the above
