The Definitive Guide to Disinfecting Lab Surfaces: Ensuring a Sanctuary of Safety and Precision

In the intricate world of scientific discovery and medical diagnostics, the laboratory stands as a bastion of precision. Every experiment, every analysis, every sample handled within its confines hinges on an often-overlooked yet critically important factor: surface hygiene. Far more than a mere chore, the meticulous disinfection of lab surfaces is the bedrock of reliable results, the frontline defense against contamination, and the unwavering guardian of human health. This comprehensive guide will transcend the superficial, delving deep into the “how” and “why” of effective lab surface disinfection, equipping you with the knowledge and actionable strategies to transform your laboratory into a sanctuary of safety and scientific integrity.

Why Lab Surface Disinfection Isn’t Just Good Practice, It’s Essential for Health

The air we breathe, the surfaces we touch – all are teeming with microorganisms. While most are harmless, the controlled environment of a laboratory, with its delicate samples, sensitive equipment, and often immunocompromised researchers or patients, magnifies the risk posed by even a seemingly innocuous microbe. Contaminated lab surfaces can lead to a cascade of detrimental outcomes, each with significant health implications:

Compromised Experimental Integrity: Imagine months of research invalidated by an unexpected bacterial growth in your cell culture, traced back to a contaminated workbench. This isn’t just a setback; it’s a loss of valuable resources, time, and potentially crucial scientific breakthroughs. The health implication here is the delay or erroneous outcome in developing new treatments or understanding diseases.
Cross-Contamination of Samples: In clinical diagnostic labs, a single contaminated surface can lead to misdiagnoses, potentially impacting patient treatment plans and health outcomes. A false positive or negative in a pathogen test, for instance, could result in inappropriate medication or a missed opportunity for early intervention.
Direct Health Risks to Personnel: Lab personnel are routinely exposed to a variety of biological materials. Contaminated surfaces can facilitate the transmission of pathogens through direct contact, inhalation of aerosols generated from contaminated surfaces, or transfer to mucous membranes. This can lead to laboratory-acquired infections (LAIs), ranging from mild illnesses to severe, life-threatening conditions. For example, a spill of a bacterial culture, if not properly disinfected, could lead to skin infections or respiratory issues if aerosolized.
Biofilm Formation: Microorganisms can adhere to surfaces and produce extracellular polymeric substances, forming biofilms. These biofilms are incredibly resistant to disinfectants and can serve as persistent reservoirs of contamination, continuously shedding microbes into the lab environment. This creates a chronic health hazard and a constant threat to experimental purity.
Damage to Sensitive Equipment: Some biological contaminants can degrade or corrode delicate lab instruments, leading to costly repairs and downtime. While not a direct health impact, malfunctioning equipment can indirectly compromise safety and accuracy.

Understanding these profound implications elevates disinfection from a routine task to a critical component of laboratory health and safety protocols. It’s about protecting the science, the samples, and, most importantly, the people who work within these vital spaces.

The Pillars of Effective Lab Surface Disinfection: A Holistic Approach

Effective disinfection isn’t a single action; it’s a multi-faceted strategy built upon several foundational pillars. Neglecting any one of these can undermine the entire effort, leaving your lab vulnerable.

1. Risk Assessment: Knowing Your Enemy

Before you even reach for a disinfectant, a thorough risk assessment is paramount. Not all lab surfaces, and not all contaminants, pose the same level of threat.

Identify the Nature of Biological Agents: Are you working with BSL-1 agents (e.g., non-pathogenic E. coli) or BSL-3 agents (e.g., Mycobacterium tuberculosis)? The type of microorganism dictates the required level of disinfection and the specific disinfectants needed. For instance, a disinfectant effective against vegetative bacteria might be insufficient for spores or non-enveloped viruses.
Assess the Frequency and Likelihood of Contamination: High-touch surfaces (door handles, microscope eyepieces, keyboards) and areas where spills are common (benchtops near centrifuges, biosafety cabinet work surfaces) require more frequent and rigorous disinfection. Consider the proximity of sterile work to potential sources of contamination.
Evaluate the Vulnerability of Samples and Experiments: If you’re working with primary cell cultures that are highly susceptible to contamination, your disinfection protocols for the surrounding environment must be exceptionally stringent. Conversely, a robust, non-biological chemical synthesis might tolerate a slightly lower level of biological cleanliness.
Consider the Health Status of Personnel: Are there individuals in the lab who are immunocompromised or pregnant? Their presence necessitates even more stringent disinfection protocols to minimize their exposure risk.

Example: In a clinical microbiology lab processing patient samples for highly infectious agents like MRSA, the risk assessment would dictate daily disinfection of all benchtops, biosafety cabinet interiors, and common touchpoints with a hospital-grade disinfectant proven effective against such pathogens. Conversely, a synthetic chemistry lab working only with non-biologicals might focus more on chemical spill cleanup than microbial disinfection on certain surfaces.

2. Disinfectant Selection: The Right Tool for the Job

Choosing the correct disinfectant is critical. A “one-size-fits-all” approach is a recipe for inefficiency and potential failure.

Efficacy Spectrum:
- Bactericidal: Kills bacteria.
- Virucidal: Inactivates viruses.
- Fungicidal: Kills fungi.
- Sporicidal: Kills bacterial and fungal spores (the most resistant forms).
- Tuberculocidal: Kills Mycobacterium tuberculosis, a highly resistant bacterium. Always check the disinfectant label for its efficacy claims. For example, a common quaternary ammonium compound (quat) might be bactericidal but not sporicidal, making it unsuitable for areas where spore-forming bacteria are a concern.
Contact Time: Disinfectants need a specific amount of time to effectively kill microorganisms. This “dwell time” or “wet contact time” is crucial and often overlooked. A disinfectant that needs 10 minutes of contact time is useless if it dries in 30 seconds. Example: If your chosen disinfectant states a 5-minute contact time for virucidal activity, you must ensure the surface remains visibly wet with the disinfectant for the entire 5 minutes. This might require re-application or using a slower-evaporating formula.
Compatibility with Surfaces: Some disinfectants can be corrosive to certain materials (e.g., bleach on stainless steel over time, alcohol on certain plastics). Always check for compatibility to prevent damage to expensive equipment and lab infrastructure. Example: While bleach is highly effective, its corrosive nature makes it unsuitable for daily disinfection of precision optical lenses or delicate electronic components. Isopropyl alcohol (IPA) is generally safer for electronics but has a more limited spectrum of activity.
Safety Profile: Consider flammability, toxicity, and irritancy to skin, eyes, and respiratory system. Proper Personal Protective Equipment (PPE) is essential regardless of the disinfectant chosen, but some agents require more stringent precautions. Example: Formaldehyde-based disinfectants are highly effective but are also carcinogens and respiratory sensitizers, requiring specialized handling and ventilation. Less hazardous alternatives should be prioritized where possible.
Storage and Shelf Life: Disinfectants have specific storage requirements (e.g., away from light, at certain temperatures) and a defined shelf life, especially after dilution. Expired or improperly stored disinfectants may lose their efficacy. Example: A 1:10 bleach solution must be prepared fresh daily, as its active chlorine content rapidly degrades, rendering it ineffective within 24 hours.

Common Disinfectant Categories and Their Applications:

Alcohols (Ethanol, Isopropanol):
- Pros: Rapid evaporation, good for surfaces where residue is undesirable, effective against many bacteria and enveloped viruses.
- Cons: Not sporicidal, flammable, can damage certain plastics over time, limited efficacy against non-enveloped viruses.
- Application: General surface disinfection, cleaning small equipment, wipe-down of biosafety cabinet interiors (after other procedures). Often used at 70% concentration for optimal efficacy.
Quaternary Ammonium Compounds (Quats):
- Pros: Good detergent properties, broad spectrum against many bacteria and enveloped viruses, low toxicity, residual activity.
- Cons: Not sporicidal, less effective against non-enveloped viruses, can leave a film.
- Application: General lab surface cleaning, routine disinfection of floors, walls, and non-critical surfaces. Often found in “hospital-grade” disinfectants.
Chlorine-Releasing Agents (e.g., Sodium Hypochlorite/Bleach):
- Pros: Broad spectrum, sporicidal at higher concentrations, virucidal, relatively inexpensive.
- Cons: Corrosive to metals, strong odor, inactivated by organic matter, short shelf life when diluted, irritating to skin/respiratory system.
- Application: Decontaminating spills of biological material, disinfection of highly contaminated surfaces, inactivation of waste. Typically used at 1:10 dilution (0.5% hypochlorite) for general disinfection, or 1:100 for blood spills.
Phenolics:
- Pros: Broad spectrum, good in the presence of organic matter, residual activity.
- Cons: Skin irritant, can be absorbed through skin, strong odor, not sporicidal, can be corrosive to some plastics.
- Application: Historically used, but less common now due to toxicity concerns, though still found in some general disinfectants for high-risk areas.
Hydrogen Peroxide:
- Pros: Broad spectrum (including some spores at higher concentrations), breaks down into water and oxygen, good for sensitive equipment in vaporized form.
- Cons: Can be corrosive to some metals, not always effective against all spores at typical concentrations, can bleach fabrics.
- Application: Surface disinfection, increasingly used in vaporized form for room decontamination.
Accelerated Hydrogen Peroxide (AHP):
- Pros: Enhanced efficacy and shorter contact times than standard hydrogen peroxide, broad spectrum, good material compatibility.
- Cons: Can be more expensive.
- Application: Often found in ready-to-use wipes and sprays for rapid, broad-spectrum disinfection.

3. Training and Competency: The Human Factor

Even the best disinfectants and protocols are useless without properly trained personnel. Human error is a leading cause of contamination.

Comprehensive Training: All lab personnel, from new hires to seasoned researchers, must undergo regular, documented training on disinfection protocols. This includes understanding the rationale behind the protocols, proper PPE use, disinfectant selection, contact times, spill response, and waste disposal.
Practical Demonstrations: Hands-on training is invaluable. Show, don’t just tell. Demonstrate proper wiping techniques, how to prepare dilutions, and how to effectively clean complex equipment.
Competency Assessments: Periodically assess personnel competency. This could involve direct observation, quizzes, or simulated scenarios. This ensures that knowledge translates into correct practice.
Understanding Contamination Pathways: Training should emphasize how contamination spreads. For instance, touching a contaminated surface and then touching one’s face, or transferring microbes from gloves to a clean keyboard. This understanding fosters a mindset of vigilance. Example: A new lab technician is trained on a biosafety cabinet disinfection procedure. The training includes a demonstration of wiping from clean to dirty areas, ensuring the entire work surface is covered, and maintaining the correct contact time. The technician then performs the procedure under supervision, receiving immediate feedback.

4. Protocol Development and Documentation: The Blueprint for Cleanliness

Written, clear, and accessible protocols are non-negotiable. They provide consistency and a reference point for all personnel.

Standard Operating Procedures (SOPs): Develop detailed SOPs for all disinfection tasks. These should include:
- Specific surfaces to be disinfected: E.g., benchtops, biosafety cabinets, incubators, centrifuges, pipettes.
- Frequency of disinfection: E.g., daily, weekly, after each use, after spills.
- Type of disinfectant to be used: Specific product name and concentration.
- Required PPE: Gloves, lab coat, eye protection, etc.
- Detailed step-by-step instructions: How to prepare the disinfectant, how to apply it, wiping technique, contact time, rinsing (if necessary), and drying.
- Spill response procedures: For different types and sizes of spills.
- Waste disposal procedures: For contaminated materials.
Accessibility: Protocols should be readily available in the lab, perhaps laminated and posted near relevant equipment, and also accessible electronically.
Regular Review and Updates: Protocols must be living documents, reviewed and updated annually or whenever new equipment, procedures, or disinfectants are introduced.
Documentation of Disinfection Activities: Maintain a log of disinfection activities, especially for critical equipment or areas (e.g., biosafety cabinets, incubators). This provides an audit trail and ensures accountability. Example: An SOP for “Daily Disinfection of Biosafety Cabinet Work Surface” might specify: “Use 70% ethanol. Don nitrile gloves and lab coat. Spray surface liberally to ensure complete wetting. Wipe from back to front, clean to dirty. Allow 5 minutes contact time. Do not dry. Dispose of wipes in biohazard bag.”

Practical Implementation: Actionable Steps for a Spotless Lab

Now, let’s translate principles into practice with concrete, actionable steps for various lab surfaces and scenarios.

1. General Lab Benchtops and Work Surfaces

These are the most frequently used surfaces and prime candidates for routine contamination.

Frequency: Daily, or after each major experimental session/change in procedure, and always after spills.
Disinfectant: A broad-spectrum, general-purpose disinfectant like a quaternary ammonium compound or 70% ethanol, depending on the expected contaminants.
Procedure:
1. Clear the Clutter: Remove all unnecessary items from the workbench. This allows for thorough cleaning and prevents contamination of items that don’t need disinfection.
2. Pre-clean: If visible dirt or debris is present, clean the surface with a detergent and water first. Disinfectants are less effective in the presence of organic matter. Wipe thoroughly to remove all detergent residue.
3. Apply Disinfectant: Liberally apply the chosen disinfectant using a spray bottle or by saturating a clean, disposable wipe. Ensure the entire surface is visibly wet.
4. Observe Contact Time: Allow the disinfectant to remain wet on the surface for the recommended contact time (e.g., 5-10 minutes). Do not wipe it dry prematurely.
5. Wipe and Dry: After the contact time, wipe the surface dry with a clean, disposable paper towel or allow it to air dry, depending on the disinfectant.
6. Dispose: Dispose of used wipes and cleaning materials in appropriate waste receptacles (e.g., biohazard bags if biological contamination is present).
Example: After completing a PCR setup, you clear the bench, spray with 70% ethanol, ensure the surface stays wet for 5 minutes, then wipe dry with paper towels, disposing of them in a biohazard bag.

2. Biosafety Cabinets (BSCs)

BSCs are critical for protecting personnel and samples from airborne contaminants. Their internal surfaces require meticulous attention.

Frequency: Before and after each use, after spills, and regularly as part of a deep cleaning schedule (e.g., weekly/monthly).
Disinfectant: 70% ethanol or a suitable broad-spectrum disinfectant. For spills, often a 1:10 bleach solution followed by ethanol.
Procedure (Routine Disinfection):
1. Activate Cabinet: Turn on the BSC fan for at least 5 minutes before and after use to purge the air.
2. Wear PPE: Always wear appropriate PPE (gloves, lab coat, eye protection).
3. Clear Items: Remove all items from the BSC, placing them in a designated clean area or decontaminating them as they are removed.
4. Spray/Wipe Disinfectant: Spray the interior surfaces (sidewalls, back wall, work surface, interior of the sash) with 70% ethanol or an appropriate disinfectant.
5. Wiping Technique: Wipe from the top down, and from the back to the front, using a clean, disposable wipe. This ensures you are always wiping from a cleaner area to a potentially dirtier area. Pay attention to corners and edges.
6. Contact Time: Allow the disinfectant to remain wet for the specified contact time.
7. Air Dry/Wipe: Allow to air dry or wipe dry with a fresh, sterile wipe.
Procedure (After Spills within BSC):
1. Containment First: Do not immediately turn off the BSC. Place absorbent material (e.g., paper towels) over the spill.
2. Apply Disinfectant: Pour or spray the appropriate disinfectant (e.g., 1:10 bleach solution for biological spills) directly onto the absorbent material, saturating it completely. Work from the outside of the spill inward.
3. Contact Time: Allow adequate contact time (e.g., 20-30 minutes for bleach).
4. Collect and Dispose: Carefully collect the saturated absorbent material and any broken glass using forceps or a dustpan. Place all contaminated materials into a biohazard bag.
5. Final Disinfection: Disinfect the entire BSC interior as per routine procedure after the spill cleanup.
6. Decontaminate Equipment: Any equipment that was in the BSC during the spill must also be decontaminated.
Example: Before starting cell culture work, you wipe down the BSC interior with 70% ethanol, ensuring the surface remains wet for 5 minutes. After completing the work, you repeat the process. If a flask of cell culture media spills, you immediately cover it with paper towels, saturate with 1:10 bleach for 30 minutes, then carefully collect and dispose of the materials before performing a final ethanol wipe-down.

3. Incubators and Water Baths

These environments are warm and humid, ideal breeding grounds for microorganisms.

Frequency: Weekly to monthly for routine cleaning, immediately if contamination is observed.
Disinfectant: For incubators, 70% ethanol, hydrogen peroxide, or a non-corrosive, broad-spectrum disinfectant. For water baths, specific algaecides/fungicides and thorough cleaning.
Procedure (CO2 Incubator):
1. Remove Samples/Shelves: Carefully remove all samples, racks, and shelves. Store samples safely in another incubator or cold room.
2. Empty Water Pan: Empty and clean the water pan thoroughly. Use a sterile cleaning brush to remove any visible biofilm or debris.
3. Disinfect Interior: Wipe down all interior surfaces (walls, floor, ceiling, door gasket) with your chosen disinfectant. Pay attention to corners and crevices. For mold growth, a more aggressive disinfectant like a dilute bleach solution may be needed, followed by thorough rinsing to prevent corrosion.
4. Disinfect Shelves/Racks: Disinfect shelves and racks separately. Autoclaving metal shelves is often ideal.
5. Refill Water Pan: Refill the water pan with sterile, distilled water and an appropriate anti-fungal/anti-algal agent if recommended by the manufacturer.
6. Wipe Exterior: Wipe down the exterior surfaces and door handle.
Procedure (Water Bath):
1. Drain Water: Drain the water bath completely.
2. Scrub and Clean: Scrub the interior walls and bottom with a brush and laboratory detergent to remove any slime or biofilm.
3. Rinse Thoroughly: Rinse multiple times with clean water to remove all detergent residue.
4. Disinfect: Fill with clean water and add a suitable disinfectant (e.g., a commercial water bath treatment, or a dilute bleach solution followed by thorough rinsing). Allow to sit for a recommended time.
5. Drain and Rinse: Drain again and rinse thoroughly with distilled or deionized water.
6. Refill: Refill with fresh, sterile water and a water bath algaecide/fungicide.
Example: Your CO2 incubator shows a faint pink discoloration (likely Serratia marcescens biofilm). You remove all samples, empty the water pan, and thoroughly wipe down the entire interior with 70% ethanol, ensuring long contact times. You also autoclave the shelves and add fresh sterile water with an antifungal agent to the pan.

4. Centrifuges and Rotors

Centrifuges can create aerosols if tubes break or seals fail, leading to widespread contamination.

Frequency: After each use (especially if tubes are known or suspected to have leaked), and as part of a weekly/monthly deep clean.
Disinfectant: 70% ethanol, quaternary ammonium compounds, or specific enzymatic cleaners for protein residues.
Procedure:
1. Unplug: Always unplug the centrifuge before cleaning.
2. Remove Rotor: Carefully remove the rotor.
3. Clean Rotor and Buckets:
  - If no visible spill: Wipe down the rotor and centrifuge buckets with a clean wipe saturated with 70% ethanol or a quat. Pay attention to the inside of the buckets and the O-rings.
  - If spill/leakage: Immediately apply disinfectant (e.g., 1:10 bleach for biologicals, followed by thorough rinsing to prevent corrosion, or a specialized enzymatic cleaner) to the affected areas of the rotor and buckets. Allow adequate contact time. Use forceps for broken glass.
4. Clean Centrifuge Chamber: Wipe down the interior of the centrifuge chamber with disinfectant.
5. Air Dry: Allow all components to air dry completely before reassembling.
6. Lubricate (if applicable): Some rotors require periodic lubrication of O-rings – consult the manufacturer’s manual.
Example: After spinning blood samples, you notice a small leak from one of the tubes in a centrifuge bucket. You immediately unplug the centrifuge, remove the rotor, and saturate the affected bucket and the inside of the rotor with a 1:10 bleach solution for 20 minutes, then rinse thoroughly with water, and wipe down the interior of the centrifuge with 70% ethanol.

5. Pipettes

Pipettes are high-touch instruments and can be a source of contamination.

Frequency: Daily for frequently used pipettes, or after each experimental session, and immediately if solution is drawn into the barrel.
Disinfectant: 70% ethanol is generally safe for the exterior. For internal contamination, follow manufacturer’s guidelines for decontamination and possibly professional servicing.
Procedure (Exterior):
1. Remove Tip: Eject the pipette tip into a waste container.
2. Wipe Down: Use a wipe saturated with 70% ethanol to thoroughly wipe down the entire exterior of the pipette, including the barrel, handle, and plunger button. Pay attention to the tip ejector.
3. Air Dry: Allow to air dry.
Procedure (Internal Contamination):
1. Manufacturer’s Guide: Refer to the pipette manufacturer’s manual for specific decontamination procedures if liquid is drawn into the pipette body. Some pipettes have autoclavable lower parts.
2. Disassembly (if indicated): Only disassemble the pipette if trained and specified by the manufacturer.
3. Decontamination Solution: Use the recommended decontamination solution (e.g., dilute bleach, specialized cleaning solution) for the specific components.
4. Rinsing and Drying: Thoroughly rinse to remove all disinfectant, and allow to dry completely before reassembly.
Example: At the end of the day, you wipe down all frequently used pipettes with an ethanol wipe, ensuring no visible residue. If you accidentally draw culture media into the pipette barrel, you immediately consult the manufacturer’s guide, dismantle the autoclavable lower section, and autoclave it.

6. Laboratory Equipment Exteriors (Keyboards, Phones, Microscope Eyepieces)

These are high-touch surfaces that can harbor a multitude of microbes.

Frequency: Daily, or before/after specific tasks that involve touching these surfaces with potentially contaminated hands.
Disinfectant: 70% ethanol is generally good. For electronics, specialized wipes or sprays designed for electronics may be preferred.
Procedure:
1. Power Off/Unplug: If possible, power off and unplug electronic devices before cleaning.
2. Wipe Down: Use a clean, disposable wipe saturated with 70% ethanol or an appropriate disinfectant. For keyboards, use a cotton swab for crevices. For microscope eyepieces, use lens paper or a specialized optical cleaning solution after a quick wipe with alcohol.
3. Avoid Excess Liquid: Do not oversaturate; excess liquid can damage electronics.
4. Allow to Dry: Ensure the surface is completely dry before powering on.
Example: Before starting molecular biology work, you use an alcohol wipe to clean your keyboard, mouse, and phone, minimizing the risk of transferring contaminants from these common surfaces to your sterile workspace.

7. Floor and Wall Disinfection

While not as critical as direct work surfaces, floors and lower walls can accumulate spills and dust.

Frequency: Regularly scheduled cleaning (e.g., weekly, monthly), and immediately after spills.
Disinfectant: A hospital-grade quaternary ammonium compound is often suitable for floors.
Procedure:
1. Clear Area: Remove obstacles from the floor.
2. Mop/Wipe: Use a dedicated lab mop or cleaning cloths with the disinfectant solution.
3. Proper Technique: Mop in sections, overlapping strokes, and frequently changing or rinsing mop heads to avoid spreading contaminants.
4. Spill Response: For spills on the floor, follow a similar protocol as for benchtop spills, increasing the area of disinfection to account for splash.
Example: The lab’s cleaning crew uses a quat-based disinfectant solution to mop the lab floors weekly, paying attention to corners and under benches.

Advanced Considerations and Best Practices

To achieve a truly definitive level of disinfection, consider these advanced points:

Environmental Monitoring: Periodically swab surfaces and culture them to verify the effectiveness of your disinfection protocols. This provides objective data and highlights areas needing improvement.
Biofilm Management: If biofilms are a persistent problem (e.g., in plumbing, water baths), consider specialized enzymatic cleaners or aggressive removal methods followed by robust disinfection. Biofilms are notoriously difficult to eradicate.
Aerosol Generation: Be mindful that spraying disinfectants can generate aerosols, potentially spreading contaminants or irritating personnel. Wiping methods are often preferred for routine disinfection.
Dedicated Cleaning Supplies: Use separate cleaning cloths, mops, and buckets for different areas of the lab to prevent cross-contamination (e.g., one set for general lab, another for biosafety cabinets).
PPE for Cleaning: Always treat surfaces as potentially contaminated when cleaning. Wear appropriate PPE, including gloves, lab coat, and eye protection. Consider respiratory protection if using volatile or irritating disinfectants.
Waste Disposal: All contaminated cleaning materials (wipes, gloves, paper towels used for spills) must be disposed of as biohazardous waste in designated, clearly labeled containers.
Post-Disinfection Verification: For critical applications, consider using ATP (adenosine triphosphate) bioluminescence swabs to objectively measure surface cleanliness after disinfection. High ATP readings indicate residual organic matter and potential microbial presence.
Manufacturer Recommendations: Always consult the manufacturer’s guidelines for specific lab equipment regarding compatible disinfectants and cleaning procedures. Deviating from these can void warranties or damage equipment.
Ventilation: Ensure adequate ventilation during disinfection procedures, especially when using volatile disinfectants.
Emergency Eyewash/Shower: Know the location and proper use of emergency eyewash stations and safety showers in case of accidental disinfectant splashes.
