Re: [114attendees] [114all] Consultation on COVID management for IETF 115 London

[Marc Petit-Huguenin <[e-mail]>]

"I refuse to breath air from any of you if it was not at least double filtered" is the only policy that matters.

>> 2.  Masks
>> We propose the following set of rules regarding masks:
>>
>> - Masks must be worn in both meeting rooms and common areas set aside for our exclusive use.  This is a tightening from IETF 114 where masks could be removed in common areas.
>>
>> - Masks can be removed for eating and drinking but that should not be an excuse to leave them off for long periods.  Previously no guidance was provided on leaving a mask off for a long period.
>>
>> - Active speakers in sessions who are at the front of the room presenting or speaking in the mic queue, can remove their mask while speaking if they need to remove the mask to be understood.  This restriction to being understood is a tightening of the rule from IETF 114.
>>
>> - Exemption certificates will not be honoured.  This is the same as for IETF 114.
>>
>> - Masks must be FFP2 or equivalent and we will continue to make those freely available.  This is the same as for IETF 114, however at that meeting there were multiple examples of people wearing surgical or even less effective masks and little action was taken.  We propose for IETF 115 that a group of senior LLC/Secretariat staff will manage this by offering those wearing such masks, FFP2 masks as replacements.
>>
>> - Finally, we note that we are in active negotiations with the venue for their staff to wear masks when in our exclusive use areas.

>>
>> 3.  Testing
>> We propose to continue with voluntary testing and to make rapid antigen tests freely available to onsite participants.

>> Please provide feedback on this proposal either to the public list admin-discuss@ietf, or directly to me at [e-mail] <mailto:[e-mail]>, before 29th August 2022.
