Short answer: Standard precautions are the baseline set of infection-prevention practices applied to the care of every patient in every healthcare setting, whether or not an infection is suspected. Their primary purpose, per the CDC, is to protect healthcare workers and prevent infection spreading between patients. The CDC lists seven components: hand hygiene, personal protective equipment (PPE), respiratory hygiene and cough etiquette, appropriate patient placement, care of patient-care equipment, textile and laundry handling, and safe injection practices.

Definition and scope
The CDC describes Standard Precautions as the practices used for all patient care, relying on a risk assessment of the interaction rather than on a patient’s diagnosis (CDC, “Standard Precautions for All Patient Care”, page dated April 3, 2024). The CDC’s 2007 Guideline for Isolation Precautions (landing page dated November 27, 2023) sets out two tiers: Standard Precautions for all patients in all healthcare settings, and transmission-based precautions as additional measures for patients known or suspected to be infected or colonized. It calls implementation of Standard Precautions the primary strategy for preventing healthcare-associated transmission among patients and healthcare personnel.
The underlying principle in that guideline is that all blood, body fluids, secretions, excretions except sweat, nonintact skin and mucous membranes may contain transmissible infectious agents.
Which agency developed standard precautions?
Standard Precautions come from the CDC and its Healthcare Infection Control Practices Advisory Committee (HICPAC). The CDC’s 2007 guideline says Standard Precautions combine the major features of Universal Precautions (1985-88) and Body Substance Isolation (1987), and that Standard Precautions were first recommended in the 1996 CDC guideline; the 2007 guideline updates and expands that 1996 version.
How standard precautions are used in practice: the seven CDC components
The CDC’s component headings, in its own wording, are:
- Perform hand hygiene. See the WHO 5 Moments for Hand Hygiene and the hand hygiene audit tool.
- Use personal protective equipment (PPE) whenever there is an expectation of possible exposure to an infectious material. See PPE types and the donning and doffing sequence.
- Follow respiratory hygiene/cough etiquette principles.
- Ensure appropriate patient placement.
- Properly handle, clean and disinfect patient care equipment and instruments/devices.
- Handle textiles and laundry carefully.
- Follow safe injection practices.
The 2007 guideline stresses that PPE use depends on the interaction and the anticipated exposure. It also notes that most elements descend from Universal Precautions, which were developed to protect healthcare personnel, while newer elements (respiratory hygiene/cough etiquette and safe injection practices, among others) focus on protecting patients.
Standard precautions vs universal precautions: what are universal standard precautions?
“Universal standard precautions” is a blend of two terms. Universal Precautions is the older concept and is still the term used in the US occupational bloodborne pathogens rule. Standard Precautions is the broader CDC framework that absorbed it. The table compares what each source says.
| Source | Term and what it says | Who it protects |
|---|---|---|
| CDC, Standard Precautions for All Patient Care (April 3, 2024) | Standard Precautions are used for all patient care and rely on risk assessment; seven components. | Healthcare workers and patients |
| OSHA, 29 CFR 1910.1030(b) and (d)(1) | “Universal Precautions is an approach to infection control” that treats human blood and certain body fluids as potentially infectious for HIV, HBV and other bloodborne pathogens; employers must see that universal precautions are observed to prevent contact with blood or other potentially infectious materials. | Employees with occupational exposure |
| OSHA, 29 CFR 1910.1030(d)(3)(i) | Where occupational exposure exists, the employer provides appropriate PPE at no cost to the employee. | Employees |
| Victoria (Australia) Department of Health, updated 22 June 2026 | Standard precautions are the work practices required for a basic level of infection prevention and control; nine elements. | Healthcare workers and patients |
In short, the OSHA rule is an employer obligation about worker exposure to blood and certain body fluids; the CDC framework governs patient care. Details of the OSHA rule are covered in bloodborne pathogens PPE.
CDC seven components vs Victoria’s nine elements
Victoria’s Department of Health lists nine elements: hand hygiene before and after patient contact; PPE (gloves, gowns or aprons, masks, face shields, eye protection); safe use and disposal of sharps; aseptic non-touch technique for invasive procedures; reprocessing of reusable instruments and equipment; routine environmental cleaning; waste management; respiratory hygiene and cough etiquette; and appropriate handling of linen.
The two lists overlap on hand hygiene, PPE, respiratory hygiene, reusable equipment and linen. Victoria names sharps disposal, aseptic non-touch technique, routine environmental cleaning and waste management as separate elements, whereas the CDC page lists “appropriate patient placement” and “safe injection practices” and points to other guidance for the rest. A facility working to a particular jurisdiction’s list should use that jurisdiction’s list.
Where it matters for labs, clinics and supply decisions
For staff who stock and manage consumables, the sources name these categories against each component. This is a map of what each component involves, not a purchasing recommendation.
| Component | Supply category the sources name |
|---|---|
| PPE | Gloves, gowns or aprons, masks, face shields, eye protection (Victoria; CDC 2007 guideline). The CDC sets what is used by anticipated exposure, not a fixed list. |
| Safe injection practices and sharps | Sharps safety is addressed in the CDC Sharps Safety workbook, to which the CDC Standard Precautions page points; Victoria lists safe use and disposal of sharps. |
| Patient-care equipment | Reusable equipment must be cleaned and disinfected or sterilized before use on another patient (CDC 2007 guideline). |
| Textiles and laundry | Linen handling is a CDC component and a Victoria element. |
Because PPE is chosen by exposure risk rather than a fixed list, the supply categories above are a map, not a standard kit. Where transmission-based precautions apply on top, additional measures are set out in the transmission-based precautions guide.
Common misunderstandings
“Standard precautions are only for patients known to be infected”
No. They apply to all patients regardless of suspected or confirmed infection status, which is why infection is not required to trigger them.
“There are four basic rules” or “four main universal precautions”
The CDC does not present Standard Precautions as four rules; it lists seven components. Four-item lists seen elsewhere are simplified teaching summaries rather than the CDC framework.
“Standard precautions mean full PPE every time”
No. The guideline ties PPE to the anticipated exposure rather than prescribing one fixed set for every interaction.
FAQ
What is the primary purpose of standard precautions?
To protect healthcare workers and prevent the spread of infection between patients, by applying the same baseline practices to all patient care (CDC, April 3, 2024).
What are universal standard precautions?
The phrase mixes two terms. Universal Precautions is the earlier blood-and-body-fluid approach, now referenced in OSHA’s bloodborne pathogens standard; Standard Precautions is the broader CDC framework that combined Universal Precautions with Body Substance Isolation.
Which agency developed standard precautions?
The CDC, through HICPAC, in the 1996 isolation guideline, updated in the 2007 guideline.
Which of the following are part of standard precautions?
Hand hygiene, PPE based on expected exposure, respiratory hygiene and cough etiquette, appropriate patient placement, care of patient-care equipment, careful textile and laundry handling, and safe injection practices. Additional contact, droplet or airborne measures belong to transmission-based precautions; see isolation signs.
What are the 4 main universal precautions?
No CDC or OSHA source lists four. The CDC lists seven components of Standard Precautions, and OSHA’s Universal Precautions is a single approach to treating blood and certain body fluids as potentially infectious.
When should standard precautions be practiced?
For all patient care in any setting where healthcare is delivered, with the level of PPE determined by the anticipated exposure.
