Ensuring a proper fit for workplace masks is essential for safety and compliance. Whether you're in construction manufacturing or healthcare an ill fitting mask reduces protection against airborne hazards. Here’s how to fit workplace masks correctly to maximise safety and comfort.
Why Correct Mask Fit Matters
A poorly fitted mask allows airborne contaminants to bypass the filter increasing exposure to harmful substances. Proper fit ensures:
- Maximum protection against dust fumes and harmful particles
- Comfort for extended wear
- Compliance with workplace health and safety regulations
Step by Step Guide to Fitting Workplace Masks
1. Choose the Right Mask Type
Different tasks require different levels of protection. Check your workplace risk assessment and select a mask rated for the hazards present. Dalton Safety offers a range of workplace masks including:
- Disposable Face & Dust Masks – Ideal for protection against dust and non-toxic particles
- Reusable Respirator Masks – Provides a higher level of protection against hazardous substances
- Powered Respirators – Suitable for prolonged use and high-risk environments requiring enhanced respiratory protection
2. Inspect the Mask Before Use
Before fitting, check for any damage loose straps or missing parts. A damaged mask won’t provide full protection.
3. Position the Mask Correctly
- Disposable Face & Dust Masks: Place the mask over your nose and mouth ensuring a snug fit against the face. Secure the straps behind your head or ears.
- Reusable Respirator Masks: Adjust the mask to cover your nose, mouth and chin ensuring a tight seal.
- Powered Respirators: Follow manufacturer guidelines to attach the hood or face piece securely.
4. Perform a Fit Check
A fit check ensures the mask seals properly.
- Positive Pressure Check: Exhale gently and feel for air escaping around the edges. If air leaks adjust the straps and nosepiece.
- Negative Pressure Check: Inhale sharply and ensure the mask collapses slightly against the face. If it doesn’t there may be leaks.
5. Adjust for Comfort Without Compromising Fit
The mask should feel secure but not overly tight. Straps should be firm but not cause discomfort. Ensure the mask sits properly and does not shift when talking or moving.
6. Maintain Facial Hygiene
Beards and stubble can interfere with mask fit. Clean shaven skin allows for a better seal. If facial hair is required for religious or personal reasons consider a powered respirator with a loose-fitting hood.
7. Replace or Clean Masks as Recommended
- Disposable Face & Dust Masks: Single use only replace after each shift or if damp or damaged.
- Reusable Respirator Masks: Clean with manufacturer approved disinfectant after each use and store in a clean dry area.
- Powered Respirators: Follow maintenance guidelines to replace filters and battery packs as required.
Face Fit Testing for Workplace Masks
Proper fit testing ensures that respiratory protective equipment (RPE) provides the required level of protection. Dalton Safety offers face fit kits designed to verify mask fit and ensure compliance with health and safety regulations. Regular fit testing is recommended especially when changing mask types or after significant facial changes (e.g. weight loss or dental work).
Common Mask Fit Mistakes to Avoid
- Wearing the mask too loosely
- Positioning the nose clip incorrectly
- Using a damaged or expired mask
- Touching the mask frequently during wear
- Failing to perform a fit check
Final Thoughts
A correctly fitted workplace mask is essential for safety. Regular training and fit testing help ensure workers are properly protected from harmful airborne hazards. If you’re unsure about mask fit or need guidance on respiratory protection consult with a safety professional.
