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.
Greenham 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
|Dust*||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*||A Normal respiratory equipment will not protect against this hazard.|
* Note Dusts, Mists and Fumes are all classified as particulate
Access and understand the hazard
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
Training for user and care of the respirator
- 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.
