Not sure how to phrase this... I have a difficult time breathing if someone sprays Windex in the vicinity.  Do either of these products emit a similar odor/gas?

Dave

No, Windex has ammonia in it and these do not. That said, they're still aerosols (although you can get the MS product in a pump sprayer so no propellant). I have trouble breathing mists too.

[Dave Pluke]

Thanks, Ike!

So, what about the stuff folks used to spray in woodwind mouthpieces - or even the bowling shoe stuff - for microphone windscreens and cables?  Effective or snake oil?

What are you cleaning, Dave? Equipment manufacturers have guidance.  My recollection of 'bowling shoe stuff's is they are phenyl phenols with some alcohol (recalling the odor). No equipment maker has suggested its use on their products.

See the Practical Show link in Pete's post for guidance valid in April, and follow any links to manufacture sites as guidance has changed.

UV-C isn't a perfect solution either. Any part of the gear that is shaded and not directly exposed to the UV-C light won't get sterilized.

The UV-C oven from OSA (see previous post) also has Ozone created by the lamps which will sterilize interiors of equipment.  Normal cycle is 30 minutes and it can accommodate 15 wireless mics or comm belt packs at a time.  we will use them on next 4 city tour starting in a week

My guess is the early ones were resistive, and one I now have trouble with is capacitive.

I am still waiting for my black nitrile gloves I ordered.

Today while shopping i wore a thin plastic disposable glove on one hand and blue nitrile on the other.

I was able to operate the touch screen through the thin plastic glove. My guess is capacitive technology.

JR

[update- the black nitrile gloves arrived and a quick check with my VOM demonstrates that they are "not" conductive, not even a little. Next week I will check them at walley world on the self checkout touch screens but I am not optimistic. /update]

So how are the employees in your shop being trained?  What are you doing when multiple users are on the same console?  And at the gig, if the artist, promoter or venue has a Covid Compliance officer, how will conflicting standards/expectations be resolved and who has ultimate authority?  Just asking because those are not clear - there aren't enough of us going back to work yet to have some examples...

Wash your hands, use hand sanitizer often.  If anyone would attempt to tell me that I need to wear gloves all night, I would simply point them to the CDC website that clearly states wearing gloves all day does nothing to prevent the spread of a virus.  The proper use of gloves is to put them on when working with potentially infected surfaces, and then immediately removing them after.  Eg, if you are cleaning and sanitizing a surface, gloves could be worn.  Wearing them for extended times does absolutely nothing, as again, the virus does not get in through the skin.  The only reason to wear gloves is to touch an infected surface, and then immediately remove the gloves and dispose of them.

If you touch an infected surface, and then touch your face, there is absolutely no difference if you have a glove on or not.  In fact, depending on the type of glove, it could be worse. The chemicals in your skin can work to kill the virus faster than a clean glove.

You're hitting on infection control protocols and yes, they are probably less important for what your or I do as system engineers or mixerpersons, but for others working with us and our gear, the needs may be different.

But as for gloves - the point is to prevent contact transmission (however small the chance of an actual infection) via the item.  IF the operator does not touch the glove surface to nose, mouth, other mucous membrane area... the operator's hands will be in the same state as when the gloves were put on.  The point is to not *transfer* contamination.  If it's not possible to de-germ the control surface, there *will* be a protocol in place.

My point about who has authority - I've been on a couple of Zoom conferences with Mixerpersons You've Heard Of and the consensus was that anyone not complying with Local Authority (compliance officer{s}) will be removed from the venue.  Having a 'tude about compliance, whether local hand, vendor or as an employee from another act... could result in expulsion from the gig.  This is why I'm asking about how, as vendors and employees of artists, this will be dealt with or even if this has been voiced in internal dialogs within an artist's management and production teams.  I see the headline act and promoter setting whatever the minimum level of standards are, and it would not surprise me to find more than 1 compliance officer - 1 from the venue, one from the promoter, and someone from the headline act's staff (stage manager, production manager) having this duty as well.  I'd expect the IATSE Local (or labor supplier) to have a compliance person, too.  In the ideal world all the details get worked out in the advance and everyone is on the same page of the same playbook...

Now back to UVC - I'll ask again if anyone using UVC is also using dosimeter cards to verify sufficiency of radiation exposure?

[Steve Litcher]

I shared this in the other sanitizing thread a while back, but I'm guessing it was likely missed.

I purchased the EVLA UVC sanitizing system from Amazon for $199 - it's fantastic because it'll hold a dozen or so microphones and it runs an 11-minute cycle.

Based on Tim Mc's info here, I also purchased dosimeter cards and tested the system today. I ran two separate tests. In the first test, I put the dosimeter card alone in the EVLA and ran it for an 11 minute cycle. Result: system passed and registered 100mJ/cm (40mJ/cm is required to kill COVID pathogens, 50mJ/cm for nearly anything else).

In the second test, I put the dosimeter card at the bottom of the unit and then threw in 6 SM58s. Ran the 11 minute cycle. Again, the card registered 100mJ/cm.

For $199 this little EVLA unit is pretty slick. It's marketed as a bottle sanitizer but it appears to have some pretty serious output/capability.

I agree that people wrongly think that gloves are protective in and of themselves.
What I think is that you are less likely to touch your face with a glove on, so there may be some benefit.

[doug johnson2]

To me, another benefit of wearing gloves is the ability to use 70% IPA much like hand sanitizer without damaging your skin.  I have doubts about the effectiveness of some/much of the generic hand sanitizer on the market.
