Respiratory Protection Guide

Introduction to Respiratory Protection

Respiratory protection is essential when working in an atmosphere contaminated by dust, vapours, fumes or gases. Many health and safety regulations place statutory demands on employers to ensure that the necessary level of protection is provided and used.

Unlike head or foot injuries, respiratory injuries are not readily apparent in the workplace. In some cases it may not be until after workers retire that symptoms occour. It is therefore important that all staff that are, or may be at risk have access to Respiratory Protective Equipment.

To help you meet Health & Safety Executive demands for personal protection, the SCAN respiratory range offers an extensive range of disposable masks and respirators.

The Hazards

Dust
Formed by the breaking down of solid materials, normally when materials are altered. For example, sanding, cutting, grinding and brushing. In general the smaller the dust particle the greater hazard that it represents. Fibres from materials should also be treated as dusts.
Vapour
A gaseous state formed by evaporation from substances that are normally either solid or liquid at room temperature (e.g. petrol, methalated spirits), many industrial processes used in degreasing vapourise particularly quickly once heated.
Fume
Formed by the vapourisation of a solid material by the application of intense heat. Extremely fine particles are formed as the fume cools and condenses. Many processes form fume; such as smelting, pouring metals and many welding applications.
Mist
Formed by processes that involve atomisation (such as spraying, cleaning and cutting/grinding using coolants) and consist of tiny liquid droplets rather like steam in a bathroom.


Disposable Masks

EN 149: Understanding the Standard

CONFORMS TO EN 149:2001 A1:2009

EN149 Filtering Face Piece for Particulates
Designed to cover the nose, mouth and chin. The construction is made of the filter material itself. To be disposed of after each period of work or 8 hour shift.

APF - Assigned Protection Factor
Level of respiratory protection that can be expected to be achieved in the workplace by 95% of adequately trained and supervised wearers using a properly fitted and functioning respiratory protective device.

OEL - Occupational Exposure Limit
The OEL is the 'Safety' line decided upon by the Health and Safety Executive.

NPF - Nominal Protection Factor
The potential maximum protection factor using the maximum percentage inward leakage permitted for a given standard class of respiratory protective device, expressed as a ratio: 100% / % allowable inward leakage


EN 140 & EN 143: Half Mask Respirators

CONFORMS TO EN 140

The European standard that covers the technical specifications for half masks which cover the nose, mouth and chin. They have their face piece manufactured from natural or synthetic based rubber allowing the mask the flexibility to fit the contours of the face.


CONFORMS TO EN 143

Covers particle filters. These are classified according to their filtering efficiency P1, P2 and P3. P1 filters are intended for use against solid particles only, P2 and P3 filters are subdivided according to their ability to remove both solid and liquid particles or solid particles only.

Respiratory protection selection guide

This table has been designed to help you select the correct SCAN respirator for a selection of hazards that may be encountered in the occupational area. It should not be used as the only means of selecting a respirator and it does not relieve the employer/user of their duties as described by COSHH and other Health & Safety Executive Regulations. It does not in any way override any recommendations made in the required appropriate COSHH/Risk assessment.
