The INDG479 document is a guide provided by the Health and Safety Executive (HSE) working alongside BSIF (British Standards Industry Federation) that offers essential advice on the fit testing of tight-fitting Respiratory Protective Equipment (RPE). It is primarily aimed at employers and competent persons responsible for carrying out fit testing.

This guide outlines:

• The legal requirement to ensure that tight-fitting RPE fits the wearer correctly.
• The importance of fit testing as part of a full RPE programme.
• The responsibilities of employers in ensuring fit testing is carried out by a competent person.
• How to conduct both qualitative and quantitative fit tests, depending on the type of RPE.
• The need for re-testing if the wearer experiences any physical changes (e.g. weight loss/gain, facial hair) or changes RPE model or size.
• The requirement to keep records of fit tests.

The INDG479 helps ensure that workers are properly protected by making sure their RPE fits correctly and provides the intended level of protection.

Key points:

• INDG479 is HSE’s guidance on fit testing tight-fitting RPE.
• It is aimed at employers and competent persons conducting fit tests.
• Covers legal duties, fit testing methods, and when re-testing is required.
• Explains the need for competent testers and maintaining fit test records.
• Supports a robust RPE programme for effective respiratory protection.
