Respiratory Protection Information

Respirators are used to protect the wearer from inhaling harmful dusts, fumes, vapours or gases. It is the responsibility of the employer to provide respirators which are applicable and suitable for the purpose intended.
Protec Direct has a comprehensive range of respiratory products from fold-flat and moulded disposable masks to powered and supplied air respirators.
To select the correct equipment follow the four steps….Identification of the hazard
Dusts* Sanding, cutting , grinding and brushing
Mists* Spraying, cutting, cleaning and grinding
Fumes* Welding, smelting and pouring metals
Vapours Methylated spirits, petrol and degreasers
Gases Air like at room temperatures and have the ability to travel a long way very quickly
Oxygen Deficient Note: Normal respiratory equipment will not protect against this hazard.
* Note Dusts, Mists and Fumes are all classified as particulate hazards.
Ensure that you fully understand the hazard and the correct respiratory equipment is selected also the correct eyewear and skin protection may need to be selected.Select the correct type of respiratory equipment
Employer must supply suitable equipment for the employee
Employer must supply training including face fit testing COSHH regulations (2002)
Qualitative fit test for disposable masks and half masks
Quatitative fit test for full face masks
Equipment must be maintained and records kept.
Qualitative Fit Test Kits….
COSHH regulations require employers to conduct fit tests for all wearers of tight fitting face pieces, such as full or half face masks and disposable masks. If the fit is inadequate it will significantly reduce the protection provided to the wearer
UK Standard Assigned Protection Factor (APF)….
Reflects the level of protection that a properly functioning respirator would be expected to provide to a population of properly fitted and trained users.
The Nominal Protection Factor (NPF)….The reciprocal value of inward leakage.
