Cleaning professionals working in laboratories, pharmaceutical facilities, and cleanrooms face a variety of workplace hazards, from chemical splashes and airborne particles to contamination risks. Selecting the right personal protective equipment (PPE) helps protect workers while maintaining the integrity of controlled environments.

This guide explains what PPE is required for cleaners, how to choose the right equipment for different tasks, and what factors should be considered when working in regulated cleanroom environments.

Quick Answer: What PPE Is Required for Cleaners?

The PPE required depends on the workplace, cleaning chemicals, and contamination risks. In most laboratory and cleanroom environments, cleaners typically require:

• Eye protection: Safety glasses or safety goggles compliant with ANSI Z87.1 and/or CSA Z94.3. Select direct ventilated or indirect ventilated goggles based on the application and splash risk.
• Face protection: Face shields used together with safety goggles when splash or spray hazards exist.
• Gloves: Chemical-resistant gloves such as nitrile, selected according to the chemicals being handled.
• Protective clothing: Cleanroom gowns, coveralls, sleeves, and chemical-resistant aprons where required.
• Respiratory protection: Surgical masks, N95 respirators, or other approved respiratory protection based on the hazard assessment.
• Foot protection: Cleanroom boot covers or dedicated cleanroom footwear with slip-resistant soles.
• Hearing protection: Required only where workplace noise exceeds permissible exposure limits.

Always perform a documented risk assessment before selecting PPE and review requirements whenever chemicals, equipment, or work processes change.

Eye and Face Protection

Eye protection is one of the most important components of a cleaner’s PPE because many cleaning tasks involve chemical splashes, disinfectants, aerosols, or airborne particles.

Direct Ventilated Goggles

Direct ventilated goggles provide maximum airflow, helping reduce heat buildup and lens fogging during extended wear.

Best suited for

• General industrial cleaning
• Low splash-risk environments
• Tasks where ventilation and comfort are priorities

Advantages

• Excellent airflow
• Reduced fogging
• Comfortable for prolonged use

Because direct ventilation allows greater air exchange, these goggles are generally recommended for environments where exposure to liquids and aerosols is limited.

Indirect Ventilated Goggles

Indirect ventilated goggles feature covered ventilation channels that promote airflow while helping reduce the direct entry of liquids and airborne contaminants.

Best suited for

• Laboratory cleaning
• Pharmaceutical manufacturing
• Biotechnology facilities
• Medical device production
• Cleanroom environments
• Areas with moderate chemical splash exposure

Advantages

• Better splash protection
• Improved contamination control
• Reduced fogging compared to fully sealed eyewear
• Comfortable for extended wear

For many laboratory and cleanroom cleaning tasks, indirect ventilated goggles provide an excellent balance between protection, visibility, and comfort.

Safety Glasses and Face Shields

Safety glasses with side shields are suitable for low-risk cleaning activities where splash hazards are minimal.

Face shields provide additional facial protection but should always be worn with safety goggles rather than replacing them.

Choosing the Right Gloves, Clothing, Respiratory Protection, and Footwear

Gloves

Choose gloves based on chemical compatibility, task duration, and dexterity requirements. Nitrile gloves are commonly used for cleaning operations, while double-gloving may be appropriate for handling more aggressive chemicals.

Protective Clothing

Select cleanroom gowns or coveralls according to your facility’s ISO classification. Chemical-resistant aprons may be required when handling corrosive or oxidizing cleaning agents.

Respiratory Protection

Respiratory protection should be selected according to the hazard assessment. Depending on the task, this may include:

• Surgical masks
• N95 respirators
• Elastomeric respirators
• Powered Air-Purifying Respirators (PAPRs)

Ensure all respiratory protection complies with your organization’s respiratory protection program.

Footwear

Use cleanroom-compatible shoe covers or dedicated cleanroom footwear with slip-resistant soles to reduce contamination and improve worker safety.

Cleanroom Considerations

The same cleaning task may require different PPE depending on the cleanroom classification.

Consider:

• ISO cleanroom classification
• Particle control requirements
• Chemical splash risks
• Material compatibility
• Proper donning and doffing procedures
• PPE maintenance and replacement schedules

Document PPE requirements for each cleanroom area to ensure consistent compliance.

Standards and Compliance

Your PPE program should align with applicable safety standards.

ANSI Z87.1 (United States)

Defines requirements for industrial eye protection, including impact resistance, optical quality, and splash protection.

CSA Z94.3 (Canada)

Canadian standard covering eye and face protection.

ISO 14644

Provides guidance for cleanroom classifications and contamination control requirements.

Safety Data Sheets (SDS) should always be used when selecting gloves and respiratory protection for chemical handling.

Improving Comfort and Compliance

Comfort directly influences PPE compliance.

Choose eye protection that offers:

• Adjustable, low-lint straps
• High-quality anti-fog coatings
• Comfortable fit during extended wear
• Compatibility with respirators, masks, and face shields
• Easy cleaning and maintenance

Properly fitted PPE encourages workers to wear it correctly throughout their shift.

Choosing Cleanroom Eye Protection

When selecting cleanroom safety goggles, consider:

• Workplace hazards
• Splash risks
• Required safety standards
• Cleanroom classification
• Compatibility with other PPE
• Anti-fog performance
• Cleaning and maintenance procedures

Klaritex supports contamination control with cleanroom-compatible eye protection solutions, including direct ventilated and indirect ventilated safety goggles, helping organizations improve worker safety, visibility, and compliance across laboratory and cleanroom environments.

Frequently Asked Questions

Do cleaners always need safety goggles?

Not always. Safety glasses may be suitable for low-risk cleaning tasks where splash hazards are minimal. For laboratory, pharmaceutical, or cleanroom cleaning involving chemicals or disinfectants, safety goggles generally provide a higher level of protection.

Which goggles are best for cleanroom cleaning?

The choice depends on the application. Indirect ventilated goggles are commonly preferred in many cleanroom and laboratory environments because they help reduce liquid splash exposure while maintaining airflow. Direct ventilated goggles are often selected where increased ventilation and wearer comfort are priorities and splash risks are lower.

What standards should PPE comply with?

Eye protection should comply with ANSI Z87.1 or CSA Z94.3, while cleanroom PPE should align with ISO 14644 requirements and your organization’s safety procedures.

Conclusion

Determining what PPE is required for cleaners begins with a thorough hazard assessment and selecting equipment that matches the work environment, cleaning chemicals, and contamination risks. In laboratory and cleanroom settings, choosing the appropriate eye protection, gloves, garments, respirators, and footwear helps protect both workers and controlled environments. By implementing standards-compliant PPE, maintaining proper training, and selecting the right combination of direct ventilated and indirect ventilated safety goggles, organizations can improve workplace safety, support regulatory compliance, and strengthen contamination control.
