PPE donning and doffing sequence (the CDC order)

Doffing is not donning in reverse, and that single fact is the whole question. The gown goes on first and the gloves last; the gloves come off first, but the gown does not come off last. “Just reverse it” swaps the gown and the mask.

Donning, in order	Gown, then mask or respirator, then goggles or face shield, then gloves — with the glove cuffs pulled over the gown sleeves (CDC).
Doffing, in order	Gloves, then goggles or face shield, then gown, then mask or respirator, followed immediately by hand hygiene (CDC).
Why gloves come off first	They carry the heaviest bioburden. The mask or respirator straps are the least contaminated item, so they are handled last.
Where the mask comes off	Outside the patient room, after the door is closed. Everything else is removed inside the room.
Eye protection	Handle only the headband or earpieces — the front is contaminated. Personal eyeglasses do not count as eye protection.
Gown removal	Unfasten the ties, pull it away from the neck and shoulders touching only the inside, turn it inside out and roll it into a bundle. Never shake it: that aerosolizes what is on it.
N95 requirements	OSHA 29 CFR 1910.134 requires a medical evaluation, fit testing for that make, model and size at least annually, and a user seal check every single time it is put on. A surgical mask is not a respirator.
PPE is picked by exposure	Standard precautions drive the choice, not the sign on the door. Anything likely to spray or splash body fluid calls for a fluid-resistant gown plus eye and mouth protection even when no isolation precautions are posted.
Hand hygiene	Alcohol-based rub containing 60–95% alcohol, or soap and running water for at least 20 seconds when hands are visibly soiled with blood or body fluids (CDC).

Where the point is lost: Gloves are not a substitute for hand hygiene. CDC lists hand hygiene immediately after glove removal as a required indication, because gloves have micro-perforations you cannot see and hands get contaminated coming out of them. Same logic on the torn-glove item: stop when it is safe, remove both gloves, hand hygiene, re-glove.
