Ms Phil Ní Sheaghdha:

What is required are frequent breaks within the roster and that is what the WHO tell us. We need frequent breaks. Ms Murphy is better able to describe this than I am.

What is required is that when someone is working and wearing PPE, he or she should be frequently relieved to hydrate and get a break from wearing it. Those committee members who have experienced wearing masks for the first time will understand that it is not very comfortable and one feels quite restricted. They can imagine what it is like wearing PPE for four hours and then being relieved for a break. The break period is the important point.
