The basics that keep your patients — and you — safe
A plain-language refresher on standard and transmission-based precautions, hand hygiene, and PPE sequence. Educational support, not medical advice — your facility's policy and official CDC/WHO guidance always come first.
Start with standard precautions
Standard precautions are the floor, not the ceiling — they apply to every patient, every time, regardless of diagnosis. Treat all blood, body fluids, secretions, non-intact skin, and mucous membranes as potentially infectious. That means hand hygiene at the right moments, the right PPE for the task in front of you, safe injection practice, respiratory etiquette, and careful handling of sharps and contaminated equipment.
When a known or suspected pathogen calls for more, transmission-based precautions layer on top: contact, droplet, or airborne — based on how the organism actually spreads. Your facility's policy and signage tell you which applies. When in doubt, ask the charge nurse or infection-prevention lead before you enter the room.
The WHO 5 Moments for Hand Hygiene
This is the time-and-place framework that catches transmission before it happens. Clean hands at each of these five moments — with alcohol-based rub or soap and water — and you break the chain.
1 — Before touching a patient
Protects the patient from germs carried on your hands. Do it as you approach, before any contact.
2 — Before a clean or aseptic procedure
Before inserting a line, preparing an injection, or handling an invasive device — so you don't introduce pathogens into a vulnerable site.
3 — After body fluid exposure risk
Immediately after contact with blood, fluids, secretions, or contaminated items — even if you wore gloves.
4 — After touching a patient
Before you move on, so you don't carry organisms to the next person or surface.
5 — After touching patient surroundings
Bed rails, the over-bed table, pumps, and monitors all harbour pathogens. Clean up before leaving the patient zone.
PPE sequence: the order that protects you
Put it on clean, take it off without contaminating yourself. The CDC sequence is worth knowing cold — the doffing order matters most, because gloves are the dirtiest thing you're wearing.
Don in this order
Hand hygiene → gown (tie it fully) → mask or N95 respirator → goggles or face shield → gloves last, pulled over the gown cuffs. Put PPE on before you enter the room.
Doff in this order
Gloves first (they're most contaminated) → goggles or face shield → gown → mask or respirator last. Remove PPE at the point of exit, slowly and away from your face.
Hand hygiene bookends everything
Clean your hands before donning and again immediately after the last piece of PPE is off and binned. If your gloves tear or you touch your face mid-care, stop and re-do hand hygiene.
Match PPE to the precaution
Contact, droplet, and airborne precautions each call for different protection. Read the door signage; don't guess. An N95 for airborne is not interchangeable with a surgical mask for droplet.
Nobody's perfect at 3 a.m. on hour eleven. That's exactly why the sequence has to be muscle memory — so when you're exhausted, your hands still do the right thing without you having to think it through.
Questions staff actually ask
Alcohol rub or soap and water?
For most clinical moments, an alcohol-based hand rub is faster and as effective — and easier on busy hands. Switch to soap and water when hands are visibly soiled, after using the toilet, and for certain organisms (such as C. difficile and norovirus) where the WHO and CDC specifically recommend washing. Follow your facility's policy.
I wore gloves — do I still need hand hygiene?
Yes. Gloves are not a substitute for clean hands. They can have micro-tears, and hands get contaminated during removal. WHO Moment 3 and the CDC are explicit: perform hand hygiene after removing gloves, every time.
Why does the PPE doffing order matter so much?
Because gloves are the most contaminated item, removing them first stops you from spreading whatever you touched onto your face, hair, or clothing. Doffing in the wrong order is one of the most common ways staff self-contaminate.
Compliance is hard on a packed shift — is that just on me?
No. Average compliance sits well below 100% across the profession for a reason — staffing, time pressure, and supply gaps all play a part. Hand hygiene is a system responsibility too: stocked dispensers at the point of care, right-sized PPE, and realistic ratios. If the supplies aren't there, flag it. That's not a personal failing.
