Evo Jaya supply Segre Dust Mask • Made in Sweden by Segre AB • Production in Örebro, Sweden • Produced only Dust Mask • Certified according to ISO 9001:2000
European standard EN 149:2001 • Previous EU standard for disposable masks: EN 149:1991. • The latest EU standard for disposable masks: EN 149:2001. • The standard specifies the limit values for each class (FFP1, FFP2 and FFP3) and the test methods to be used to test masks. • EN 149:2001 also specifies that all masks must filter both solid and liquid-borne particles (SL).
Requirements/tests of EN 149:2001 • Visual Inspection • Packaging • Materials • Practical performance tests • Finish • Compatibility with skin • Flammability • Carbon dioxide • Head harness (straps) • Field of vision • Exhalation valve The field of vision is acceptable if determined so in practical performance tests. Exhalation valves shall be protected against or be resistant to dirt and mechanical damage. It shall continue to operate correctly after a continuous exhalation flow of 300 l/min over a period of 30 s. The carbon dioxide content of the inhalation air (dead space) shall not exceed an average of 1%. The head straps should be designed so the mask can be removed easily. It should be adjustable or self-adjusting and robust to keep the mask in position. The material shall not be of highly flammable nature. When tested the mask shall not burn or continue to burn for more than 5 seconds after removal from the flame. Materials that may come into contact with the wearer’s skin shall not cause irritation or any other negative effect to health. Parts that likely will come in contact with the wearer shall have no sharp edges. The mask shall undergo practical performance tests under realistic conditions to find possible imperfections. Materials should be suitable to withstand handling and wear over the period for which the masks are designed to be used. Masks shall be packaged in such a way that they are protected against mechanical damage and contamination before use. The visual inspection shall include the marking and the information supplied by the producer.
Dusts • Created when solid materials are broken down into fine particles that float in the air before settling under gravity. • Dusts are produced in grinding, drilling, blasting, sanding, milling etc. • Dust, including nuisance dust, has an OEL that cause long term health problems. • Wood dusts cause respiratory problems which can lead to cancer of the sinuses and nose – Emphysema. • Organic dusts set off allergies and asthma fever.
Toxic dusts • Definition: a solid, mechanically produced particle. How the dust is created is of importance as it will define it’s toxicity. • Metal and Organic dusts are harmful to the whole of the body, not just the lungs. • Generally a minimum level of protection would be FFP2 or other specialised product. • Examples; Asbestos, Lead, Chrome, Silica, Grain, Cement. • Silica dusts vary in toxicity and are so small that they go deep into the lungs causing irreversible damage. • Asbestos is a barbed particle that hooks itself into the lungs and causes fatal infection.
Fumes • Created when solid materials vaporise under high heat and then condense into fine particles that float in the air. • For instance, metal vapour cools and condenses into tiny particles, less than one micron in diameter. • Metal fumes can form when welding, smelting and pouring of molten metal. • Fumes vary in toxicity and cause damage to the respiratory system and other vital organs.
Mists • Small liquid droplets formed from liquid materials by atomisation and condensation processes. • Mists can form when spraying, plating, mixing, cleaning etc. • Examples; Water based pesticides.
Organic vapours • Definition: gaseous form of a substance which is normally solid or liquid until temperature or pressure is applied. • Liquids change in to a vapour and mix with the surrounding atmosphere. • Generally have addictive smells. • Examples: Petrol, Alcohol, Styrene and Solvents.

Filter classes in EN 149:2001 • FFP1 or just P1: for basic use. • FFP2 or just P2: for standard use in high particle concentrations. • FFP3 or just P3: for advance use in extremely high particle concentrations. • Segre’s masks, CN Particlefilter, have colour coding: FFP3 FFP1 FFP2
Logic product names • CN = Range name • P1–P3 = Filter class • C = Carbon mask • V = Valve • HF = Hydrogen Fluoride
Comfortable masks; CN P1 and CN P1 V • FFP1: nominal protection factor: 4 • Protect against: wood dust, quartz dust, allergenic particles, pollen, concrete dust, chemical particles, polishing dust etc.
Carbon masks; CN P1 CV and CN P2 CV • Nominal protection factor: 4 and 12 • Activated carbon; removes strong or unhealthy odours, organic vapours, acid gases, metal fume, ozone etc. FFP1 Agriculture Chicken farms Sanitation Clearance Refineries Veterinary Horticulture FFP2 Welding Casting Grinding Extreme Sanitation
Material • Optimal combination of filter material • Multiple layers • Electrostatic filtration • Mechanical filtration • Outside layer/carbon • Minimal breathing resistance • High filtration
Exhalation Inhalation • The CN masks have three layers Meltblown (mechanical filter) Microfilter layer (electrostatic filter) Filter against coarse particles
Several benefits for users • Hygienic plastic bag • Convenient pocket size • Easy to put on • Adjustable straps • Simple to adjust nose clip • Easy to adapt to perfect fit • Good sight • Easy to speak through
