Hi Monique - Here are the ones I know about,

I guess that I am lucky as I no longer seem to have any problems with caps not being put back on bottles.  I am also curious about vented caps.  I generally use bottles no larger than 4L, but have two different style of caps.  My glass bottles have more threads than the plastic ones.  Can anyone share where they are getting vented caps for these bottles?

Thank you,

We require secondary containment on all waste bottles so I do not see this as a huge issue.  The use of these funnels has significantly reduced problems here and we have never had one knocked over to leak.  With the funnels, you do not get bottles exploding and it is much easier to get people to keep their waste containers closed.  I was constantly telling people to remove their standard funnel and close the bottle.

Safety decisions are about managing risks for the best outcome.  Some codes/policies actually make things less safe in particular situations.

The  funnel apparatus does not prevent spills if the waste container is accidentally knocked over onto its side. The waste system must be a closed system. 

N.B.: I just asked my lab staff to test the vented caps (I was able to get a few sample caps - I really don't want to buy 1000 at a time) for the 4L bottles by filling the bottle with water and turning it upside down. They don't leak! They're perfect for waste that has to off-gas in a 4L bottle.
Now I need to find 5-gallon plastic waste containers with vented lids.

We, the willing, led by the unknowing, are doing the impossible for the ungrateful. We have done so much, for so long, with so little, we are now qualified to do everything with nothing. Teresa Arnold
