Editor's Notes
- According to AS/NZS1715:2009, respiratory protection shall be adapted according to the working environment, the task to be performed and the user. The assigned protection factor is lower than the nominal rating. The assigned protection factor is not based solely on laboratory measurements, it also takes into account actual measurements taken in the workplace. The assigned protection factors relate to the recommended values published by the Health and Safety Executive (HSE).
- Normal oxygen concentration is 21%; must not fall below 19.5% Clear warning characteristics (except for substances such as mercury, isocyanates).
- Contaminants can get into the body in a variety of ways: Via the mouth, e.g. when we eat Through the skin when we touch various substances, e.g. different types of fluid Via the lungs when we breathe
- Particles are split into three groups 1. Inhalable dust (100 μm) 2. Thoracic dust (10 μm) 3. Respirable dust (4 μm) Collectively, these 3 groups are called TOTAL DUST The total dust concept will be changed to Inhalable dust Particles that are sufficiently small are drawn down into the lungs with each breath and may lead to sensitive people suffering breathing difficulties.
- There are "only" two types of contaminant - gases and particulates can usually be easily filtered out. NB Purifying respiratory protective devices cannot be used in instances where there is a lack of oxygen. Appropriate breathing apparatus must be used instead.
- Definition of particles: dust, smoke, mist (Aerosol)
- Silicosis = pneumoconiosis, caused by the inhalation of silica dust Solvents can cause brain damage and permanent nerve damage. Symptoms mimic those of an alcoholic - forgetfulness, shivers and irritability! Many contaminants are carcenogenic, e.g. petrol, TRE (trichloroethylene) and asbestos A foetus is generally exposed to the same health hazards as its mother! Lead, cadmium and mercury Many substances are allergenic (e.g. isocyanites) or may act as a catalyst for asthma. Remember, the only safe exposure to substances that are allergenic or carcenogenic is zero exposure. Therefore, try to use equipment with as high a protection factor as possible.

- Activation Chemical activation Carbonised peat Chemical + 700°C Washing, drying, Ground to powder or extruded into pellets Steam activation Coal and coconut Coking Activation with steam 1000°C Impregnation Impregnated active carbon is prepared using chemicals that react with certain gases that would otherwise pass straight through. Examples of impregnations: Chromium, copper, potassium carbonate, potassium iodide, TEDA, silver, sulphur, etc. Chemical activation Steam activation Carbonised peat, coal and coconut Chemical + 700°C Washing, drying, Ground to powder or extruded into pellets
- Example of Ammonia penetration; Point A = smell limit; Point B = Hygienic Limit Value, i.e. Ammonia has clear warning characteristics Example of Isocyanate penetration Point A = Hygienic Limit Value Point B = smell limit, i.e. Isocyanates have no warning characteristics, use compressed air initially. Gas filters only protect against gas not particles !
- Gas filters must be marked with both a letter and colour code!
- Product Description Gas and fumes are filtered away in the active carbon. Sundström has a wide range of gas filters. Gases and vapors are adsorbed/absorbed by the active carbon
- NB Particle filters only protect against particles Indicated by the letter code "P" and colour code "White" Particle filters intended for single shift use must be marked "NR" Particle filters that can be re-used must be marked "R" Split into three classes, the higher class(es) covering those below Large filter surface provides low breathing resistance and long filter service life Filter to be replace when increase breathing resistance felt P1 Not effective against carcinogens, radioactive substances, micro-organisms (e.g. viruses, spores) or biochemical substances (e.g. enzymes, hormones) P1 and P2 Not effective against micro-organisms (e.g. viruses, spores) or biochemical substances (e.g. enzymes, hormones) P3 Protects against all types of particle * Filtering quota = 100 % contaminant / filter penetration. The filtering quota refers only to the filter material, i.e. it does not take into account deficiencies in the fit!
- Particle filter SR 510 marking SR 510 P3 SR 610 marking SR 610 P3 NB - cannot be combined with a gas filter!
- Theoretical filtering quota refers only to the filter material (separation level), i.e. it does not take deficiencies in the fit into account! Example 1,000,000 particles in the air when using FFP3 1 000 000/100 = 10,000 particles behind filter 1,000,000 particles in the air when using SR 510 1,000,000/33,000 = 33 particles behind filter Although this only theoretically applies to the filter, it has a major significance on the respiratory protective device's total leakage.
- Sundström particle filters SR 510 and SR 610 are not affected by air speed, humidity or temperature.
- A combination filter must always be used whenever gas and particles occur at the same time.
- We all have slightly different facial features, and this is something that can affect leakage.
- Remember, you should be smooth shaved before using half or full facemasks. Filter: Gas filters do not leak. Particle filters leak depending on separation level. The SR 510 has a maximum separation level of > 99.997 %, i.e. < 0.0003% leakage Low inhalation resistance in the filter minimises the risk of leakage. Exhalation valve: Clean and intact Easily accessible Low exhalation resistance Between face & mask Clean shaven Size Wide and flexible seal against face High level of comfort affords longer wear time
- Wear time = the actual length of time the protective device is used during the working day High level of comfort affords longer wear time. The wear time for a vacuum mask is, to a large extent, determined by the level of comfort. Example of comfort factors for a half and full facemask.: Inhalation resistance Exhalation resistance Mask structure softness and fit Harness design and adjustability An achieved effective protection factor of 1000 will be reduced by 90% if respiratory protection is not used for 5 minutes in an 8 hour working day, or if it leaks for an equally long period of time!
- Based on a large number of "Portacount" quantitative fit tests conducted on Sundström's half facemasks since 1989.
- A half facemask covers the user's nose, mouth and chin, and is held in position by an adjustable strap. When used in combination with a filter, the user breathes in the air. Exhalation air is released through one or more exhalation valves. There are particle filters, filters for gases/fumes and combination filters. Best suited for use at lower exposure levels and where there is no potential for eye irritation. The principle is based on achieving a good seal between the mask and face, which forms a vacuum inside the mask during inhalation. Vacuum masks increase pressure on the respiratory system and are most suited for use with low workloads or during shorter periods of activity. Sundström produces half facemasks, full facemasks (and fan-assisted respiratory protective equipment, see step 2)
- Body and membrane made from silicon Robust structure Does not degrade over time Flexible, which affords a high level of comfort and a good fit Heat finished, which means that no silicon oil is released from the material (200 degrees for 6 hours) Stable and well-balanced mask Two sizes (S/M and M/L) Dual exhalation valves Body uses muscles when inhaling. Exhalation is passive. In other words, it is important to have a low exhalation resistance.

- A full facemask covers the user's eyes, nose, mouth and chin, and is held in position by an adjustable harness. When used in combination with a filter, the user breathes in the air. Exhalation air is released through one or more exhalation valves. There are particle filters, filters for gases/fumes and combination filters. Thanks to a large contact surface area on the face and more substantial strapping, full facemasks provide a higher level of protection. The principle is based on achieving a good seal between the mask and face, which forms a vacuum inside the mask during inhalation. Vacuum masks increase pressure on the respiratory system and are most suited for use with low workloads or during shorter periods of activity. Sundström produces half facemasks, full facemasks (and fan-assisted respiratory protective equipment, see step 2)

- Check that there are no scratches, deformations, etc. in the mask. Check that the harness has ”normal” elasticity and that the inhalation membrane and the exhalation membrane are in position. It is important that the valve covers on the maskare also in position as they protect the exhalation valve against external influences. Lost valve covers may lead to leakage! Fitting accessories, e.g. hoods, must be done before the user enters the contaminated environment! Connect test disc 322 to where the pre-filter normally sits (make sure that it goes in straight and covers the entire filter!). Take the mask in one hand and place it against your face without putting on the harness. Suck air into the mask. If the face seal is good, it will remain on your face for approximately 5-10 seconds. If this does not happen, visually inspect the mask a second time. Beards/stubble may cause leakage. Get your shaver out! Hang the mask around you neck so that ”the main plate” ends up on the "nose" section of the mask.. Perform an initial adjustment of the harness. Normally, a perfectly tensioned harness means that the nose section of the mask is at the same height as the user's breastplate. 5. The mask is put on by first placing the chin into the mask before it is positioned against the nose. The harness is then put into position. The crown plate must be positioned at the top ofå the rear section crown. Adjust the mask so that it sits comfortably on your face. The mask must not be too tight to the face, as this can be uncomfortable and lead to leakage! Check the directions for use!
- Store the mask and filter dry and clean in airtight packaging! Never clean the mask using strong solvents (e.g. acetone) as it may become deformed!!
