Frequently Asked Questions

01: What is a Full Face Mask?

Full face respirator masks cover the full face & provide protection from hazardous particles, gases as well as providing protection for the eyes with a panoramic protective screen. A Full Face Respirator with filters will protect against highly toxic hazards including fumes & fine toxic dust.

02: What safety standards are there for Full Face Dust Masks?

In the UK, Full Face Dust Masks & Respirators are classified to the EN136 standard and used in negative pressure systems. These are classified into 3 classes:

Class 1 – Light duty

Class 2 – General duty

Class 3 – Heavy-duty protection

03: Do Full Face Respirator Masks provide a higher level of protection than Half Face masks?

Full Face masks provide protection for the whole face including the eyes and mouth and are recommended for very dusty environments. The correct mask filters (Gas/Particulate filters) need to be selected depending on the hazard encountered however P3 filters provide an increased protection level APF 40 when used with a full face mask respirator.

04: Do I require a face fit test for a Full Face Mask / Full Face RPE ?

Personnel that use Full Face Dust Mask Respirators are required to have passed a face fit test. This face fit test must be quantitative only as per HSE recommendations. Qualitative face fit tests cannot be used.

05: Can I wear a Full Face Mask if I have a beard?

This is dependent on the degree of growth. Limited growth would be fine with a non powered Full Face Respirator as long as there is no beard growth where the mask seals around the face. An enclosed powered air system is recommended as a specific Full Face mask for beards.

06: What filters are required for Full Face Masks?

The mask filters required are dependent on the hazard encountered. These maybe gas & vapour filters or particulate.

A Organic fumes

B Inorganic fumes

E Sulphur Dioxide

K Ammonia Green

P Particle White
