Why Proper Donning and Doffing Matters on Nashville Construction Sites

Personal Protective Equipment (PPE) is the frontline defense against a wide range of hazards on construction sites, from falling debris and chemical splashes to airborne particulates and noise. In a growing city like Nashville, where new high-rises, infrastructure improvements, and residential developments are reshaping the skyline, the risk profile can shift daily based on weather, site layout, and the phases of construction. Proper donning—putting on PPE—and doffing—removing PPE—are not merely procedural steps; they are critical actions that can prevent injuries, reduce exposure to toxic substances, and ensure compliance with federal and local safety regulations.

This article provides expanded best practices for PPE donning and doffing tailored specifically to Nashville construction projects. We cover the science behind correct sequences, common mistakes to avoid, and strategies to address the unique challenges of working in Tennessee’s hot, humid climate.

The Importance of Correct PPE Procedures

Correctly donning and doffing PPE serves multiple purposes that go beyond simply wearing the equipment. When workers put on PPE in the right order and check fit, they maximize protection. When they remove it methodically, they minimize the risk of transferring contaminants from gloves, sleeves, or respirators to skin, clothing, or the surrounding environment. On a Nashville construction site, this can mean the difference between a minor incident and a lost-time injury or long-term health issue.

Regulatory Compliance and Liability

The Occupational Safety and Health Administration (OSHA) sets clear standards for PPE use in construction under 29 CFR 1926.95 – 107. Employers must assess hazards, select appropriate PPE, and train workers on proper use, including donning and doffing. Failure to follow these steps can lead to citations, fines, and increased liability in the event of an accident. In Nashville, the Metro Nashville Occupational Health and Safety Office also enforces local regulations that align with state and federal guidelines, making local knowledge essential for contractors.

Preventing Contamination in Multi-Hazard Environments

Construction sites often present simultaneous hazards: silica dust from concrete cutting, lead from old paint, welding fumes, chemical sealants, and biological hazards like mold. Improper doffing can spread these contaminants to clean areas, vehicles, or break rooms. For example, removing a respirator after grinding without first cleaning gloves can transfer silica particles to the face. A structured doffing sequence—especially for respiratory protection and gloves—acts as a containment barrier. The CDC’s NIOSH guidelines on PPE use offer evidence-based sequences for donning and doffing that apply directly to construction settings.

Best Practices for Donning (Putting On) PPE

Donning PPE in a systematic way ensures each piece functions as designed and that no gaps in protection occur. The following expanded practices apply to the most common PPE categories on Nashville construction sites.

General Donning Order

While the exact order can vary by equipment type, a standard sequence recommended by safety professionals is:

  1. Foot protection – Steel-toed boots or metatarsal guards first, to provide a stable base.
  2. Head protection – Hard hat, adjusted to sit level and snug.
  3. Eye and face protection – Safety glasses or goggles, and face shield if needed.
  4. Hearing protection – Earplugs or earmuffs, inserted after hard hat is secure.
  5. Respiratory protection – N95 or half-face respirator, fit-checked before proceeding.
  6. Upper body – High-visibility vest or coveralls, over the respiratory gear.
  7. Hand protection – Gloves last, to avoid contamination of inner layers.

This order minimizes the risk of needing to adjust or remove lower PPE after donning higher items, which could introduce contaminants.

Step-by-Step Donning for Key PPE Items

Hard Hat

  • Inspect for cracks, dents, or suspension damage. Replace if worn.
  • Adjust headband to sit 1–1.5 inches above eyebrows, level on head.
  • Ensure suspension straps fit snugly without pressure points.
  • If wearing a chin strap or face shield mount, install before placing on head.

Respirator (N95 or Half-Face)

  • Perform a user seal check every time: cover the exhalation valve and exhale; cover the cartridge inlets and inhale. No air leaks.
  • For N95, position straps: bottom strap below ears, top strap above.
  • Bend nose wire to shape over bridge of nose.
  • Ensure no facial hair interferes with seal—clean-shaven is best for tight-fitting respirators.

Consult the OSHA Respiratory Protection Standard for additional fit testing requirements.

Gloves

  • Choose material appropriate for the hazard: leather for impact, nitrile for chemicals, cut-resistant for sharp materials.
  • Don clean gloves last, after all other PPE is in place.
  • Avoid touching face or adjusting respirator after gloving.
  • Check for tears or holes by inflating with air or visual inspection.

Fit and Comfort Considerations for Nashville’s Climate

Nashville summers bring high heat and humidity, often above 90°F with dew points that make PPE feel oppressive. Sweat can compromise the fit of hard hats, goggles fog up, and respirators can become uncomfortable. To maintain proper donning and ensure PPE stays on all day:

  • Choose lightweight, breathable hard hat liners (sweatbands) that improve comfort without interfering with suspension.
  • Use anti-fog wipes or inserts for safety glasses.
  • Select respirators with exhalation valves to reduce heat buildup.
  • Take hydration and rest breaks in shaded or air-conditioned areas to avoid heat stress—dehydrated workers are more likely to remove PPE improperly.

Projects should integrate heat safety into PPE training, aligning with OSHA’s Heat Illness Prevention resources.

Best Practices for Doffing (Removing) PPE

Doffing is often rushed at the end of a shift, but this is when contamination transfer is most likely. A deliberate, methodical removal sequence protects both the worker and the next user of reusable equipment.

General Doffing Order (Reverse of Donning)

  1. Gloves – Remove first, using a technique that turns them inside out (see below).
  2. Respirator – Remove by handling straps only, not the front.
  3. High-visibility vest or coveralls – Unfasten and remove without touching outer surfaces.
  4. Hearing protection – Remove carefully to avoid earwax contamination.
  5. Eye/face protection – Handle by temple or side pieces, not lenses.
  6. Hard hat – Remove by the brim or suspension, not the shell.
  7. Foot protection – Last, if working in heavily contaminated areas.

Glove Removal Technique

This is the single most critical doffing step:

  1. Grasp the palm of one gloved hand with the opposite gloved hand and peel off, turning the glove inside out.
  2. Hold the removed glove in the still-gloved hand.
  3. Slip two fingers of the bare hand inside the remaining glove at the cuff, being careful not to touch the outer surface. Peel it off, turning it inside out over the first glove.
  4. Dispose immediately in a designated waste container.

Practice this technique during toolbox talks. A visual demonstration from the CDC is available on CDC’s PPE Doffing Guidelines.

Handling Reusable PPE

Hard hats, goggles, and some vests are reused daily. After doffing, workers should:

  • Wipe down hard hat suspension and shell with mild soap and water. Do not use solvents that weaken plastic.
  • Clean safety glasses with a designated lens cleaner and microfiber cloth.
  • For reusable respirators, disassemble cartridges, wash facepiece with mild detergent, dry, and store in a sealed bag away from dust.
  • Inspect all reusable items for cracks, worn straps, or discoloration. Replace as needed.
  • Store PPE in a clean, dry locker or designated area, separate from street clothes.

Common Doffing Mistakes Specific to Nashville Construction

Field observations and incident reports reveal recurring errors on Nashville sites:

  • Gloves removed by pulling at fingertips – This can fling contaminants into the air or onto clothing. Always use the peel-and-roll technique.
  • Respirators removed by grabbing the front – This transfers contamination to hands and face. Use the straps only.
  • Hard hat removed while still wearing gloves – If gloves are contaminated, touching the hard hat spreads hazards. Remove gloves first.
  • Skipping hand hygiene after doffing – Even if gloves are removed correctly, residual contamination can remain. Wash or sanitize immediately.
  • Mixing clean and used PPE – Placing a used hard hat on a clean bench where coffee or lunch boxes sit risks cross-contamination.

Supervisors should conduct spot checks during breaks and at shift end to reinforce correct doffing behavior.

Nashville-Specific Challenges and Solutions

Heat and Humidity

As noted, Nashville’s climate leads to sweat that degrades PPE materials and reduces wear time. Solutions include:

  • Scheduling high-heat tasks early morning or late afternoon.
  • Providing cooling vests or neck wraps that do not interfere with PPE.
  • Using disposable sweat-absorbing liners inside hard hats that can be replaced daily.
  • Ensuring ample water stations and rest breaks in shaded areas per OSHA recommendations.

Mixed-Use Site Zones

Many Nashville projects involve renovations of existing structures that may contain lead paint, asbestos, or mold, alongside new construction. In such mixed zones, workers moving between areas must doff and don different PPE levels. For example, a worker leaving a lead-abatement area must follow a strict doffing sequence to avoid tracking dust into clean zones. The site safety plan should define transition zones where donning/doffing occurs, with marked lines and separate waste bins.

Language and Literacy Considerations

Nashville’s construction workforce is diverse, with many Spanish-speaking workers. PPE training should be delivered in the workers’ primary language, using visual aids and hands-on demonstrations. Written instructions should be available in English and Spanish. The OSHA Stop Construction Falls campaign offers multilingual resources that can be adapted for PPE.

Developing a PPE Donning and Doffing Training Program

Best practices are only effective when workers know them and practice them regularly. A robust training program for Nashville construction projects should include:

  • Initial training for all new hires, with hands-on demonstration of donning and doffing sequences.
  • Annual refresher covering changes in equipment or site hazards.
  • Toolbox talks once a month focusing on one PPE item (e.g., “Respirator fit check week”).
  • Competency evaluations where workers demonstrate proper technique under observation.
  • Signage at PPE stations showing step-by-step graphics in multiple languages.

Use the OSHA Construction Training Resources to structure your program.

Conclusion

Proper donning and doffing of PPE is not a one-time lesson but a daily practice that protects every worker on a Nashville construction site. By following the correct sequences, maintaining equipment, and adapting to local climate and language needs, contractors can reduce injuries, prevent long-term health damage, and remain compliant with OSHA and local regulations. Invest in regular training, monitor compliance, and foster a culture where safe PPE use is second nature. The result is a safer, more productive work environment for everyone building Nashville’s future.
