Qualitative Face Fit Testing (Hood/Taste Method)

The qualitative hood and taste method is a widely used face fit testing approach for tight fitting disposable and reusable respirators. It is commonly applied across construction, manufacturing, facilities management and general industry where a pass or fail outcome is required to confirm that a mask forms an effective seal against the wearer’s face.

Course Overview

Employers by law are required to fit test every employee who is required to wear a tight-fitting respirator no matter how long they are required to wear one or the frequency. We are Fit2Fit approved and as such you can rest assured our testing procedures are of the highest standard and will enable you to meet your legal duties.

The Qualitative Face Fit Testing method is used to conduct testing on FFP disposable respirators and re-usable cartridge half masks only.

This is a subjective method based on the test subject’s ability to detect/taste a test solution. Typically, a bitter or sweet solution, we usually advise using bitter as standard as people in general tend to taste bitter more easily than the sweet solution…we all like our fizzy drinks and sweets so our taste buds can be somewhat dulled to a sweet stimulant.

This method makes use of a test capture hood. The wearer is asked to perform seven exercises whilst regular measured doses of the test solution are sprayed into the hood.

All staff successfully fitted will be issued with an official Advanced Safety Group Fit Record detailing all the data and mask type. This can be kept by the business to prove that that individual has been tested appropriately in line with COSHH and HSE standards.

Quantitative face fit testing using ambient particle counting method delivered by Advanced Safety Group Ltd

Quantitative Face Fit Testing (Ambient Particle Counting Method)

The ambient particle counting method is a highly accurate face fit testing approach used for tight fitting respirators where a measurable fit factor is required to confirm protection. It is widely used across healthcare, construction, manufacturing and emergency services where respiratory protection is critical and exposure risks are higher.

Course Overview

Employers by law are required to fit test every employee who is required to wear a tight-fitting respirator no matter how long they are required to wear one or the frequency. We are Fit2Fit approved and as such you can rest assured our testing procedures are of the highest standard and will enable you to meet your legal duties.

The quantitative method or ambient particle counting method gives an objective and quantifiable assessment of a facial fit to an individual mask. It provides a numerical result known as a fit factor which is set at various limits depending on the type of mask tested. 

This method allows you to test all tight fitting RPE including:

  • Disposable respirators/masks
  • Re-usable cartridge half masks
  • Full face masks (full face masks can only be tested using this method)
  • Positive pressure full face masks

This test is conducted using an ambient particle counting machine, typically using a TSI Portacount or AccuFit 9000. These machines use lasers to count the number of particles inside a mask and compare it to the number of particles outside the mask in order to calculate the integrity of the seal.

All staff successfully fitted will be issued with an official Advanced Safety Group Fit Record detailing all the data and mask type. This can be kept by the business to prove that that individual has been tested appropriately in line with COSHH and HSE standards.

Face Fit Testing FAQs

Yes. Employers must ensure tight fitting respiratory protective equipment is suitable and effective for the wearer under the Control of Substances Hazardous to Health Regulations. HSE guidance requires face fit testing to confirm that respirators provide an adequate seal and the intended level of protection.

The correct method depends on the type of respirator and level of protection required. Qualitative testing is commonly used for disposable and half mask respirators, while quantitative testing is preferred where higher levels of protection are required or a measurable fit factor is needed. Selection should be based on risk assessment and equipment specification.

The face fit testing guidance is for a period of two years from test date, retesting is required whenever there are changes to the respirator model, facial features, weight, facial hair, medical condition or workplace risk. Regular review should form part of an effective respiratory protection programme and ongoing COSHH compliance.

Any employee required to wear tight fitting respiratory protective equipment must be face fit tested. This includes roles in construction, healthcare, manufacturing, emergency services, facilities management and environments where exposure to dust, fumes, chemicals or airborne hazards exists.

Yes. Face fit testing is commonly delivered on site so staff can be tested using the respirators they wear in their actual working environment. This ensures practical compliance and minimises disruption to operations.
