One other interesting consideration about media of this sort in a lab situation:  not only might a person not hear alarms, but they might not notice that a piece of machinery is not operating properly.  Maybe the fan on the freezer is straining, or (heaven forbid) the centrifuge is unbalanced.  The statement that =93this machine is making a weird noise=94 may be an early warning signal that something is going wrong.  If we hear the =93weird noise=94 early on, repairs can begin before any significant damage has occurred.


Besides all that, I personally find background music distracting when I=92m working in a lab.  I can=92t even read when the radio is on.

It does seem that this situation depends very much on the culture and 
experience in the lab. We have not addressed ear buds in our chemical 
hygiene plan (but now it will). In our industrial lab, the staff is very 
experienced in laboratory procedures and safety and they are mature adults 
as opposed to young adults, They know to keep the volume down and also to 
run the wire inside their lab coats. No one instructed the staff on this. 
As for the radio, it is never loud enough to prevent hearing the phone or 
an alarm. 

An interesting perspective also on the hearing impaired in the laboratory. 
However, in a lab that disability would have accommodated in any case. For 
instance, if there is a flashing light that is used as an alarm as an 
accommodation,. I think that would change the way ear buds and radios are 
handled as well. CHPs are supposed to be flexible, after all.

Aside from all of the valid reasons against personal music players in any laboratory setting previously mentioned, there is also the issue of potential transfer (by either direct (touch) or indirect (fumes/vapors)) of chemicals onto the device, which then carries that outside the lab.
