Understanding PPE and the Significance of Removal Order

Personal protective equipment (PPE) serves as a vital shield against numerous workplace hazards including infectious droplets, chemicals, excessive heat, and debris. Key sectors such as healthcare, construction, manufacturing, and public safety rely on PPE to minimize exposure risks, ensuring both productivity and personnel safety. Healthcare workers, industrial staff, and lab technicians can refer to NIOSH’s PPE guidelines for up-to-date research, performance standards, and approval processes NIOSH Personal Protective Equipment.

Executing gear removal in a structured sequence substantially lowers the risk of self-contamination. Incorrect procedures may allow contaminants to transfer from surfaces onto skin, clothing, or nearby environments. The CDC's recommended doffing sequence, although developed for clinical environments, serves a wide range of applications, emphasizing hand hygiene throughout the process. The authoritative protocol can be accessed with visual aids here: CDC PPE Sequence (PDF). Following an established PPE removal order strengthens safety protocols and streamlines decontamination and waste management.

Proper doffing techniques extend beyond hospital environments to industries like asbestos abatement, hazmat response, industrial cleaning, and food processing. OSHA mandates a thorough hazard assessment, appropriate equipment selection, user training, and enforcement of written procedures that include detailed doffing instructions and disposal practices OSHA Personal Protective Equipment. When dealing with mixed exposures, align procedures with CDC guidelines, customizing them based on contaminant type, decontamination infrastructure, and specific tool use. Documenting PPE removal order within job hazard analyses, toolbox talks, and visible checklists is equally essential.

Removing PPE: What Comes Last?

Face coverings like medical masks or respirators are removed last. This step follows exiting exposure zones and complete hand hygiene, as well as the removal of eye protection, aligning with the CDC’s specified sequence for clinical and various other settings CDC PPE Sequence (PDF). Use this resource to adapt these recommendations for diverse field tasks.

Step-by-Step Guide to Removing PPE

Adhering to a proper PPE doffing sequence is essential for minimizing the risk of self-contamination during high-risk tasks. Following a sequence endorsed by the CDC can significantly enhance safety in healthcare settings. The recommended order: remove gloves, gown, perform hand hygiene, exit care area if needed, remove eye protection, mask/respirator, and perform hand hygiene a second time. For complete guidance, refer to the CDC's PPE guidelines for healthcare professionals here.

Establishing a Safe Doffing Zone

A well-organized doffing area is crucial. Create a clearly marked zone with a posted step-by-step sequence. Place a sturdy waste bin, equipped with a foot pedal, within reach. Ensure alcohol-based hand rub is conveniently stocked nearby, and have disinfectant wipes ready for cleaning reusable eye protection. If respirator reuse is allowed, have a clean storage bag staged and ready. In locations where staff allows, consider using a trained observer or buddy system. Always inspect PPE for visible contamination before commencing the removal process. Take a moment to pause, breathe, and mentally visualize each action before making the first move.

Detailed CDC-Approved Sequence with Hygiene Checkpoints

Move deliberately to avoid self-contamination, prioritizing deliberate and slow actions. Before touching contaminated surfaces, perform hand hygiene meticulously. Undertake the removal of tape or ties securing the gown using a clean-to-dirty technique. Begin by removing gloves; grasp the outside cuffs and alternate hands during removal. Clean hands thoroughly post-glove removal.

Remove the gown by breaking ties and rolling it inside-out, away from the body, then dispose it in the designated waste stream. Sanitize hands again using alcohol-based hand rub (ABHR) or thoroughly wash with soap and water. If local policies mandate, exit the patient or hot zone for out-of-room doffing.

When removing eye protection, handle only the earpieces or headband. Decontaminate reusable goggles or face shields per facility protocol, then sanitize hands thoroughly, allowing them to dry completely. Before the final steps, remind yourself “mask last” to ensure the correct order. Remove masks or respirators by the straps, touching nobody parts. The bottom strap comes off first, then the top. Avoid contact with the face, respirator front, or inner surface. For N95 masks meant for reuse, place them into a breathable, labeled container.

For Powered Air-Purifying Respirators (PAPR), power off, and remove hood by contacting clean edges only. Disinfect PAPR components according to the manufacturer’s instructions for use (IFU). Conduct another thorough hand hygiene session, inspecting for any residue or contamination. Check your skin for splashes or contamination signs and wash exposed areas promptly if needed. If re-entering an exposure area, don fresh respiratory protection.

Document the doffing process if incidents or breaches occur. Restock supplies and replace waste bags following current policy. Regularly rehearse this PPE doffing sequence in drills to maintain proficiency. Finally, dispose of all PPE correctly according to OSHA’s disposal requirements. For additional resources, consult OSHA’s PPE programs for training and hazard controls here.

Why Remove the Mask Last?

Ensuring respiratory protection remains on until the final step reduces exposure risks from doffing-generated aerosols and possible contamination transfer to vulnerable facial areas. According to U.S. OSHA guidelines, PPE programs should prevent exposure throughout the entire removal process. Respiratory equipment must adhere to 29 CFR 1910.134 and comply with broader PPE standards under Subpart I. The Centers for Disease Control's healthcare protocols establish a removal sequence maintaining facial protection until completely out of exposure zones, significantly decreasing contact with persistent contaminants. The World Health Organization also endorses this methodology for infectious threats. Maintaining facial protection last shields mucous membranes from contamination.

Recommendations for "Remove Mask Last":

• Doffing often disturbs particles; face coverings block inhalation during garment and glove removal.
• During PPE removal, hands frequently acquire contaminants; last-off strategies lower hand-to-face transfer risks.
• Masks or respirators safeguard the nose, mouth, and adjacent skin until entirely outside exposure zones.
• Initial removal of goggles or face shields prevents strap interference while sustaining respiratory coverage.
• "Remove mask last" aligns with validated procedures, promoting safety without additional complexity.
• Room aerosol clearance can take time; masks last-off timing helps evade breathing leftover contaminants.
• Handling only the straps during final removal minimizes contact with potentially contaminated mask fronts.

Correct PPE Doffing Sequence:

1. Remove gloves.
2. Take off gown.
3. Perform hand hygiene.
4. Exit exposure area if applicable.
5. Remove eye protection using straps.
6. Use straps to remove mask or respirator— "remove mask last."
7. Sanitize hands again.

Operational Advice:

• When dealing with facial protection, touch only straps or elastics; avoid the contaminated front.
• Replace visibly soiled or damaged PPE immediately.
• Procedures must integrate OSHA directives and CDC methods to guide training, fit testing, and task supervision effectively across various settings.

For procurement and supervisory roles, enforcing the "remove mask last" approach standardizes team practices, minimizes cross-contamination risks, and maintains safety performance without hindering workflow efficiency.

Frequently Asked Questions on PPE Removal

Quick answers to common questions surrounding personal protective equipment (PPE) removal provide essential guidance for teams applying safety techniques consistently in the field. Familiarize with the following queries to enhance safety protocols and further verify them against cited standards.

What is the Correct Sequence for PPE Removal According to the CDC?

Following the Centers for Disease Control and Prevention (CDC) guidelines ensures correct doffing order: gloves first, then gown, exit patient area, perform hand hygiene, then remove face shield or goggles, followed by the mask or respirator. Importantly, the N95 or elastomeric respirators should be taken off only after exiting the room with the closed door. The CDC’s detailed posters and guides offer visual aids and variations applicable to different PPE sets: CDC PPE Sequence (pdf), CDC Infection Control PPE.

When Should Hand Hygiene Occur During Doffing?

Perform hand hygiene right after glove removal, once again after shedding all gear, and whenever hands become potentially contaminated. Effective methods include using an alcohol-based hand rub (containing 60–95% alcohol) or soap and water when hands appear dirty. Resources are available: CDC Hand Hygiene, WHO Hand Hygiene.

Why Keep Face Protection on Until Last?

Maintaining face protection as the final barrier while leaving exposure zones minimizes self-contamination from droplets or aerosols. Following this sequence limits potential risks, as highlighted by both CDC and WHO PPE Doffing.

Managing Eye Protection

When removing eye protection, touch only straps or earpieces. Reusable items should be placed in designated containers for cleaning, using EPA List N products, followed by hand hygiene. Check APIC PPE Best Practices and EPA List N for specifics.

Differences for N95, Elastomeric, or PAPR Devices

Instructions vary for respirators. Remove N95/elastomeric ones last, outside exposure zones. For PAPR, follow facility protocols and manufacturer’s instructions for blower, hood, and battery handling, ensuring disinfection aligns with IFU and policy NIOSH Respirators, CDC Respiratory Protection.

Proper Removal Location

Designate a doffing space nearby with necessary tools like waste containers, hand rub, and wipes. Employing an observer can reduce contamination and workflow errors. Further details at CDC PPE Guidance.
