First Aid Infection Control: Practical Rules That Never Delay CPR
The moment you kneel beside someone who needs help, assume every drop of blood or body fluid carries risk and act accordingly. Clean or sanitise your hands, put on gloves, use a barrier for rescue breaths, and contain any spill before it spreads. None of this should delay CPR or stopping severe bleeding. If you’re exposed to blood or body fluid, flush the area and get it checked by a health professional straight away.
TL;DR:
Hand hygiene should be performed before and after contact with casualties, especially after removing gloves or dealing with contamination, to prevent infection spread.
Use disposable gloves, eye protection, masks, and gowns based on the level of risk, ensuring correct application and removal to avoid self-contamination.
Irrigate wounds with tap water or saline until visibly clean, avoid deep digging for debris, and seek medical review for deep, heavily contaminated, or extensive wounds.
Spill cleanup requires sealing the area off, using disinfectants at the correct dilution, and disposing of contaminated materials properly, with heavy contamination needing professional cleaning.
Any blood or body fluid exposure, particularly involving sharps, must be reported immediately, followed by prompt medical assessment to optimize post-exposure treatment.

What standard precautions mean for first aid responders
Standard precautions are the baseline rules that guide every patient interaction, regardless of what you know or think you know about their health. They cover hand hygiene, personal protective equipment, environmental cleaning and respiratory hygiene, and they apply to every casualty because infection status is rarely known at the scene, according to standard precautions guidance. The equipment you reach for depends on what you expect to happen, not on how the person in front of you looks or seems.
A simple mental checklist helps this become automatic rather than something you have to think through under pressure:
Clean your hands before and after any contact with the casualty.
Put on gloves whenever blood or body fluid is likely.
Add eye protection or a mask if splashing is possible.
Clean surfaces and dispose of waste as soon as the situation allows.
When to wash hands or use alcohol rub, and how to do it properly
Hand hygiene matters most at a handful of critical moments: before and after giving direct care, immediately after removing gloves, after touching anything that might be contaminated, and after dealing with a spill. Soap and water is the right call when hands are visibly dirty or after contact with diarrhoea, vomiting or suspected gastrointestinal illness, while alcohol based hand rub works well the rest of the time, per NICE infection prevention guidance.
Pro tip zone aside, here’s the technique that actually works:
Wash for around 20 seconds with soap and water, or rub hands with alcohol gel until they’re dry.
Use a paper towel to turn off the tap if you’ve just washed your hands.
Always clean your hands again straight after you take gloves off.
Gloves don’t replace hand hygiene. Clean hands before gloving and immediately after you remove them because gloves can tear or let contamination through at the cuff, a point NICE’s guidance makes clear.
Selecting and using PPE in first aid: gloves, masks and eye protection
Single gloves cover most direct contact with blood or wounds. Double gloving suits higher risk tasks such as handling sharps or heavily soiled dressings. Add an apron or gown when clothing might be splashed, and eye protection or a mask when fluid could spray, for instance during wound irrigation or vomiting. A respirator is reserved for situations that generate fine airborne particles, which is uncommon in routine first aid but worth knowing about if you work near such procedures.
Correct removal matters as much as correct application. Peel gloves off from the wrist without touching the outer surface, and always follow with hand hygiene, since healthcare guidance stresses that PPE must be donned and removed correctly to avoid self contaminating.
Disposable gloves (several pairs)
Eye protection or safety glasses
A face shield or pocket mask with one way valve
Disposable aprons
Pro Tip: Keep a spare set of gloves in a side pocket, separate from your main kit, so a torn glove never leaves you without a clean pair.
Cleaning, irrigating and dressing wounds safely
Good wound care in the field is about removing contamination without doing more damage than the injury already has.
Irrigate with plenty of clean tap water or saline rather than scrubbing hard; a PMC review found that tap water irrigation carries no higher infection risk than sterile saline when sterile water isn’t available.
Keep flushing until the wound looks visibly clean, rather than stopping after a token rinse.
Pat the area dry and cover it with a clean, non stick dressing.
Refer for medical assessment if the wound is deep or penetrating, heavily contaminated, located on the hand, foot or face, still has foreign material in it, or is a laceration longer than 5 centimetres.
Check the casualty’s tetanus immunisation status and advise a medical review when it’s out of date or unknown. Field first aid isn’t the place to manage tetanus prophylaxis beyond that referral.
Avoid digging around in a wound to find debris you can’t see. Aggressive cleaning harms healthy tissue and can push contamination deeper rather than clearing it.
Isolate and clean blood or body fluid spills safely
Cordon off the spill, put on gloves at minimum, and if there’s broken glass or a sharp object involved, lift it with tongs or forceps rather than your fingers. Soak up the fluid with disposable paper towels before you disinfect, since cleaning a wet spill just spreads it further.
Use a disinfectant suited to the surface and likely pathogen, and follow the label’s dilution and contact time exactly, as core infection prevention practices recommend.
Let the surface dry fully before anyone walks on it or touches it again.
Bag used towels and gloves for disposal rather than leaving them on a bench.
Carpet and other porous surfaces have real limits. Note the spill and arrange professional cleaning if the contamination is heavy.
Immediate steps and reporting after sharps injuries or exposure
A sharps injury or splash to the eyes or mouth needs a calm, quick response, not panic.
Wash a puncture wound with soap and running water, without squeezing it hard to force fluid out, which doesn’t reduce risk and can irritate the tissue.
Flush eyes or mouth with water for several minutes if fluid has splashed there.
Report the incident through your workplace or clinical exposure pathway without delay.
Seek medical assessment promptly, since post exposure options for hepatitis B, hepatitis C and HIV risk depend on timing, according to a CDC job aid on blood and body fluid exposure.
Reporting late can close the window on treatment that works best when started early, so treat it as part of the first aid response, not paperwork for later.
Balancing infection control with life saving actions
None of this should ever slow down CPR or bleeding control, as explained in body armor and combat medics trauma techniques. Check for danger, call emergency services, and start chest compressions or apply direct pressure to severe bleeding even without a full PPE kit to hand. If you can’t or won’t give rescue breaths, compression only CPR is a recognised option, and a barrier device helps if one is within reach. Healthdirect’s first aid guidance is clear that infection control measures must never delay emergency care.
Safe disposal of contaminated waste and cleaning of reusable equipment
Puncture resistant sharps containers are non negotiable for needles and blades. Used dressings, gloves and other contaminated items belong in clinical waste bags where they’re available, kept separate from general rubbish.
Clean and disinfect reusable kit, such as resuscitation masks or splints, exactly as the manufacturer directs before it goes back in the bag.
Replace gloves, dressings and other consumables as soon as stock runs low rather than stretching what’s left.
Log the incident per your workplace policy and tell the casualty to see a doctor if there’s any doubt about their wound or exposure.
How hands on training improves infection control in first aid
Reading a checklist and performing it correctly under stress are different skills. Practical training, including donning and doffing drills, spill clean up practice and wound care repetition, builds the muscle memory that stops hesitation when it counts. We’ve found that responders who’ve rehearsed these sequences physically make fewer errors when a real incident demands both speed and care.

FAQ
What are 5 infection control procedures?
The core procedures are hand hygiene, using PPE matched to the task, cleaning and disinfecting surfaces and spills, safe handling and disposal of sharps and waste, and respiratory hygiene such as covering coughs. These form the basis of standard precautions applied in every first aid situation.
What are the 5 basic principles of infection control?
The basic principles are treating every casualty as a possible infection risk, cleaning hands at key moments, wearing PPE suited to the exposure, decontaminating surfaces promptly, and disposing of waste safely. These apply regardless of how healthy a casualty appears, because infection status is rarely known in the field.
What are the 7 standard precautions for infection control?
Definitions vary slightly by source, but a common version includes hand hygiene, PPE use, safe injection practices, sharps safety, respiratory hygiene, environmental cleaning and safe handling of linen or waste. Core infection prevention practices set these out for healthcare and first aid settings alike.
What are the 7 basic steps of first aid?
A typical sequence is checking for danger, assessing the casualty, calling emergency services, checking airway and breathing, starting CPR if needed, controlling severe bleeding, and monitoring until help arrives. Healthdirect stresses that none of these steps should be delayed by infection control concerns.
How soon should I report a sharps injury?
Report it immediately through your workplace or clinical exposure pathway and seek medical assessment the same day. Prompt action matters because post exposure options for risks like hepatitis B, hepatitis C and HIV work best when started early, according to a CDC job aid on blood and body fluid exposure.
