Menu Copyright © 2005 by The SEA Group FILTERS 1: Particle Filters Skip to Half Masks
5
Menu Copyright © 2005 by The SEA Group Two main types Mechanical impact (such as Sundström) A fine mesh barrier that lets air through but not particles Electrostatic Electric charged filter material acts like a “glue”, making particles stick to filter surface
6
Menu Copyright © 2005 by The SEA Group The 1 st problem with ELECTROSTATIC: It’s like throwing tacks at a magnet: Throw them SLOWLY, and the magnet catches them all
7
Menu Copyright © 2005 by The SEA Group …but throw them QUICKLY, and some will get through The 1 st problem with ELECTROSTATIC:
8
Menu Copyright © 2005 by The SEA Group The 1 st problem with ELECTROSTATIC: REDUCTION in some filters up to
9
Menu Copyright © 2005 by The SEA Group So how can electrostatic filters pass standards tests?
10
Menu Copyright © 2005 by The SEA Group So how can electrostatic filters pass standards tests? Because standards tests are done at 95 litres/minute… …while people often breathe at 300-500 litres/minute!
11
Menu Copyright © 2005 by The SEA Group The 2 nd problem with ELECTROSTATIC: Moisture | Humidity | Oil mist
12
Menu Copyright © 2005 by The SEA Group The 2 nd problem with ELECTROSTATIC: Oil mist is EVERYWHERE!
13
Menu Copyright © 2005 by The SEA Group Mechanical Impact Not affected by air speed Not significantly affected by humidity or oil mist Only keeps on collecting particles Gets “better” the more particles are caught Replace when hard to breathe through
14
Menu Copyright © 2005 by The SEA Group Sundström particle filter P100 Dry particles (dust) Wet particles (aerosols, sprays) Smoke and fumes Fibres Mould Bacteria and viruses
15
Menu Copyright © 2005 by The SEA Group When to replace If there is any damage to the filter or When the filter feels hard to breathe through or After 4-6 weeks’ use
16
Menu Copyright © 2005 by The SEA Group Comparison Other brands: Every week* Sundström: Every 4-6 weeks Particle filter replacement *) Average filter life 40 hours, as stated by manufacturer
17
Menu Copyright © 2005 by The SEA Group FILTERS 2: Gas Filters
18
Menu Copyright © 2005 by The SEA Group Adsorption efficiency of gas filtres NOT affected by air flow rate
19
Menu Copyright © 2005 by The SEA Group Pulsating air flow MAY affect life span (still 100% adsorption, but time before breakthrough may be shortened)
20
Menu Copyright © 2005 by The SEA Group Colour coding Organic vapour AmmoniaAcid gas - Inorganic Gas Particles
21
Menu Copyright © 2005 by The SEA Group Combination filters If you need protection against BOTH particles and gas: A: Use a special combination filter B: Make a combination filter by pressing a particle filter onto the front of a gas filter
22
Menu Copyright © 2005 by The SEA Group To separate a combination filter Insert a coin or similar between the rim of the particle filter and the lug on the side of the gas filter Twist apart
23
Menu Copyright © 2005 by The SEA Group When to replace According to a replacement schedule Replacement of gas filters depends on: Type of contaminant Concentration of contaminant Temperature and Humidity Workload
24
Menu Copyright © 2005 by The SEA Group FILTERS: 3: Pre-filters
25
Menu Copyright © 2005 by The SEA Group Pre-filters… Should ALWAYS be used Protect the main filter Are low cost items Should be replaced AT LEAST once a day
26
Menu Copyright © 2005 by The SEA Group Sundström half mask SR100 Skip to Fitting
27
Menu Copyright © 2005 by The SEA Group Features Mask body and filter holder are made of a SINGLE PIECE of silicone material
28
Menu Copyright © 2005 by The SEA Group Features Large surface area of the filter holder means a lighter filter and lower breathing resistance
29
Menu Copyright © 2005 by The SEA Group Features Filter holder situated very low on the mask. This means much better weight balance on the face
30
Menu Copyright © 2005 by The SEA Group Features Continuous one-piece head harness works like shock absorbers on a car: weight and tension are evenly distributed
31
Menu Copyright © 2005 by The SEA Group Features Head harness is easily removed for cleaning or replacement
32
Menu Copyright © 2005 by The SEA Group Features Specially designed valve cups with internal deflectors to eliminate clogging of the valve by spray or aerosols
33
Menu Copyright © 2005 by The SEA Group Features Exhalation valves have a 90 degree flange to stabilize movement and ensure rapid return to closed position
34
Menu Copyright © 2005 by The SEA Group Features Sealing surfaces (rims) are sandblasted (matted) for slip-free seal. A deep chin cup ensures secure fit and good balance
35
Menu Copyright © 2005 by The SEA Group Features The mask if fitted with a water-proof bar-coded name tag for easy identification and tracking
36
Menu Copyright © 2005 by The SEA Group Features The special test adapter can be used on the wearer’s own mask without leaving any marks
37

38
Menu Copyright © 2005 by The SEA Group Knowledge base A wealth of information and knowledge support is available on CD-ROM and Internet
39
Menu Copyright © 2005 by The SEA Group Training program Sundström respiratory protection is backed by a solid authorisation program
40
Menu Copyright © 2005 by The SEA Group How to fit Make sure the mask is: Intact Fully assembled Fitted with correct filters Clean Yours 1 Skip to Maintenance
41
Menu Copyright © 2005 by The SEA Group How to fit Sling neck strap around your neck Start by placing your chin in the chin cup Cup the mask up over your mouth and nose 2
42
Menu Copyright © 2005 by The SEA Group How to fit Pull the head strap over your head Head pad should rest on the crest of your head NEVER fit head harness over helmet, cap, ear muffs or other head gear 3
43
Menu Copyright © 2005 by The SEA Group How to fit Adjust the tension by using the buckle, if needed 4
44
Menu Copyright © 2005 by The SEA Group How to fit Pull a few times on the BOTTOM strap. This will create more tension in the upper strap, resulting in greater lift and optimum balance 5
45
Menu Copyright © 2005 by The SEA Group Leakage test Perform a leakage test every time you will use the mask Place the leakage test disk instead of a pre-filter in the pre-filter holder Breathe in and hold your breath The mask collapses against your face. It should stay collapsed until you release your breath. If it returns quickly to normal shape, you have a leakage problem
46
Menu Copyright © 2005 by The SEA Group Annual fit test Individual fit testing using PortaCount or similar equipment should be performed at least once a year This will ensure that people whose facial features have changed (due to dentures, lost teeth, severe acne, facial scarring etc) are still receiving the protection they need
