Single use respirator, which when worn securely on the face reduces the exposure to airborne particle hazards. Half Mask Filter Respirator • A face piece that covers the nose and mouth. • A filter or filters. • A system of one-way valves. • A head harness that keeps the respirator securely on the face The valves enable the wearer to breathe in through the filter which cleans the contaminated air before it reaches the lungs. The air the wearer breathes out is then released through the exhalation valve(s) without any contaminated air leaking in. Full Face Filter Respirator • An inner mask that covers the nose and mouth. • An outer mask with visor that covers the eyes and face . • A filter or filters. • A system of one-way valves. • A head harness that keeps the respirator securely on the face The valves enable the wearer to breathe in through the filter which cleans the contaminated air before it reaches the lungs. The air the wearer breathes out is released through the exhalation valve(s) without any contaminated air leaking in. The full face respirator not only filters out harmful materials from the air, but also protects the face and eyes from dust, gas, liquid splashes and impact. Type Features How it Works Types of Air Supply Supplied Air Respirator • Face pieces including or compatible with supplied air connection. • Loose-fitting hoods, helmets or blouses with supplied air connection. A supplied air respirator is a respirator to which clean air is pumped through a hose or air line from a remote source. Self-Contained Breathing Apparatus (SCBA) • Carrying a bottle of clean, compressed air on the back. Supplied Air • Pumping clean air from a remote source through a hose to a mask or hood around the head. Powered Air Purifying Respirator (PAPR) Breath-Responsive Respirator (FPBR): • A motor-driven fan which draws contaminated air through a filter and then provides clean air to the face. Intrinsically Safe Powered Air Purifying Respirator (PAPR): • A motor-driven fan which draws contaminated air through a filter and then provides clean air to the face in explosive/ignitable environments when worn with suitable face piece. Filter Type Use Filter Life Particle filters Protects only against particles, that is, dust, aerosols, smoke, mould, bacteria etc. A particle filter does NOT protect against gases and vapours. Some particle filters are single use such as filtering face pieces, and others are not and can be reused (these filters absorb more and more particles and will eventually clog, it will then become more difficult to breathe through the filter). Gas Filters/Cartridges Protects only against gases and vapours. There are different kinds of gas filters/cartridges for different kinds of gases. A gas filter/cartridge does NOT provide protection against particles. Absorbs gas until they become saturated. After this, the filter will simply not absorb any more gas. There is no difference in breathing resistance, and it is unlikely that the user will be able to tell by smell or taste that the filter has become ineffective; the gas will just go right through the ‘spent’ filter. This is why it is very important to replace gas filters/cartridges before the end of the filter lifetime. This has to be done according to a time schedule based on the type and concentration of the gas or vapour. Combination Filters/ Cartridges Protects against both particles and gases. Different combination filter/cartridges are used depending on the gas or vapour present in the air. Lifetime expires when either the particle component becomes clogged and hard to breathe through, or when the time is up for the gas component.
