Particle filters:

Particle filters are divided in 3 classes:

• P1 low effect-filter
• P2 medium effect-filter
• P3 high effect-filter.

Class P1 has the lowest degree of excretion and therefore only protects to a limited extent from dust (solid particles). The filter must not be used if the limit value of the pollutant is below 5 mg / m3. Examples of dust types that the filter does not protect are asbestos fibers and quartz, metal and wood dust.

Class P2 has a higher degree of excretion and therefore protects to a greater extent. It can be used against harmful and toxic dust, but not against radioactive dust, bacteria and viruses. These filters are available in two types, partly for use only against solid particles and partly for use against solid particles and liquid aerosols.

Class P3 has the highest degree of excretion and protects as class P2 as well as against radioactive dust, bacteria and viruses. The filter is usually for use against both solid particles and liquid aerosols. Not all P3 filters are suitable for use in half masks.

Gas filters:

Filter type A protects against vapors from organic solvents with a boiling point above 65 ° C, eg mineral turpentine, toluene, xylene and butyl acetate. A filters have brown color code.

Filter type AX protects against vapors from organic solvents with a boiling point of / or below 65 ° C. Filter type AX is only available in one class. The filters are disposable filters and must be discarded the same day they were used. AX filters have brown color code.

Filter type B protects against chlorine and cyanobiocyte and the like. gases. B filters have gray color code.

Filter type E protects against sulfur dioxide and the like. gases. E-filters have yellow color code.

Filter type K protects against ammonia and the like. K filters have green color code.

There are filters that cover several types A, B, E and K at the same time. Filters for several different gases and combinations of particles and gases have color code for each type.

Filter type Hg-P3 protects against mercury vapors and particles. Hg-P3 filters have red / white color code.

Filter type NO-P3 protects against nitrous gases and particles. NO-P3 filters have blue / white color code. However, AT recommends compressed air.

Filter types Hg-P3 and NO-P3 are only available in one class.

Note that full and half masks are equipped with some very thin rubber inhalation and exhalation membranes.

In order for the mask to be dense and functioning properly, it is important that the membranes are intact. It is therefore necessary to check this periodically and to replace defective membranes.

Types of respiratory protection:

Filtrating short-time mask
Disposable mask covering nose and mouth. Consists of filter material through which the inhalation and exhalation air passes. To facilitate breathing, the mask may be provided with an exhalation valve.

The masks must be labeled with the filter class as well as an R (reusable) for multiple use masks or NR (non reusable) for single use masks.

Some masks are labeled with, for example, FFP2D. The D-mark (Dolomit test) means that the material has a particularly large dust capacity, so that the resistance only increases slowly. Masks with D-marking are suitable for multiple use.

• Class P1 has the lowest excretion rate and therefore only protects to a limited extent from dust (solid particles). If the filter has been tested according to EN 149: 2001, the filter protects against both solid particles and liquid aerosols. The filter must not be used if the limit value of the pollutant is below 5 mg / m3. Examples of dust species that the filter does not protect against and therefore must not be used are asbestos fibers and quartz dust.
• Class P2 has a higher degree of excretion and therefore protects to a greater extent. It can be used against harmful and toxic dust, but not against radioactive dust, bacteria and viruses. These filters can protect only against solid particles or both from solid particles and liquid aerosols. If the filter has been tested according to EN 149: 2001, the filter protects against both solid particles and liquid aerosols.
• Class P3 has the highest excretion and protects as class P2 as well as against radioactive dust, bacteria and viruses. The filter is usually used for both solid particles and liquid aerosols. If the filter has been tested according to EN 149: 2001, the filter protects against both solid particles and liquid aerosols.

Half mask:

Mask covering the chin, mouth and nose. The mask is equipped with an inhalation valve, an exhalation valve and is for the application of filters.

The masks can also be fitted with solid filters and must be labeled with the filter class as well as an R (reusable) for multi-use masks or NR (non reusable) for single use masks.

Some masks are labeled with, for example, FFP2D. The D-mark (Dolomit test) means that the material has a particularly large dust capacity, so that the resistance only increases slowly.

Masks with D-marking are suitable for multiple use.

Full face mask:

As the name says, the mask covers the entire face - chin, mouth, nose and eyes. The mask is equipped with an inhalation valve, an exhalation valve and interchangeable filters.

Full face masks are also supplied for use with external air supply.

Turbo equipment:
Filtering respirators equipped with a turbo unit, ie. a battery-operated motor which blows air into the respirator through one or more filters.

The turbo gear is combined with a full or half mask, hood or a body with a tight-fitting visor.

Air supplied respiratory protection:
Respiratory protection is provided with clean air, usually from a compressor which, through a pipe or hose system as well as a filter unit, blows in the air.

The equipment is combined with a full- or half-mask, hood or a body with tight-fitting visor.

Choice of respiratory protection:

When choosing a respirator, it is important to consider the following: What air pollution is this? - dust, fumes, gases, aerosols or a combination - and at what concentrations?

• Is there a risk of oxygen deficiency? In many wells, tanks and other containers there is a risk of oxygen deficiency.

What kind of freedom of sight and movement is wanted from the equipment?
All masks more or less restrict vision and can therefore increase the risk of ignoring hazards.

How big the work load?
When working with heavy and stressful work that results in heavy breathing, a turbo or fresh air supplied respirator will definitely be preferable.

Use for how long?
If you work with respirators for more than 3 hours in total on one working day, the air must be supplied either from turbo equipment or compressor / fresh air supply.

When supplied air has to be chosen? 

• when there is - or may be - oxygen deficiency, ie less than 17% oxygen content in the inhalation air.
• when air pollution occurs in high concentrations.
• when the composition and / or concentration of the air pollution is unknown.
• when there is no suitable / approved filter for the type of pollution
• when prescribed by law.

Protective gloves requirements for mechanical testing

EN 388:2016
MECHANICAL EFFECTS
Gloves are tested against following effects:
1 = lowest value, X = not tested, O = Didn't reach minimum requirements.

EN ISO374:2016

& EN ISO374-2:2014

Protective gloves for protection against chemicals & micro organisms General requirements

EN ISO374:2016
AGAINST DANGEROUS CHEMICALS & MICRO ORGANISMS
The standard indicates requirements for the functionality of gloves regaridng protection of the wearer against penetration, permeation and degradation by chemicals and micro organisms.

The standard classifies three types of gloves after protection level (A, B and C).

EN ISO 374-2:2014
PENETRATION

The gloves must pass the air or water penetration test and meet the established AQL inspection level. In an air penetration test, the interior of the glove is pressurized with air and the surface is checked for holes. In a water penetration test, the glove is filled with water and checked for the presence of water droplets on the outside after a specified period. AQL (Accepted Quality Level) is a quality assurance measure based on an ISO 2859-1 sampling procedure used by manufacturers to measure the likelihood of pinhole defects in a batch of gloves. An AQL of 1.5 accepts the statistical probability that the lot contains less than 1.5% faulty gloves.

EN 16523-1:2015

Test method for measuring the resistance of the materials used for the personal protective equipment in relation to the penetration of hazardous chemicals at the molecular level and during uninterrupted contact. The resulting value is the penetration time or the time it takes for the dangerous liquid or gas to come in contact with the skin. The glove is classified according to the performance level performance from 1 to 6. (see table at top right).

This standard lists 18 chemicals. The minimum penetration time for a type A glove is 30 minutes. (level 2) for 6 chemicals, for type B it is 30 min. for at least 3 chemicals, and for type C it is 10 min. (level 1) for at least 1 chemical on the list.

TYPE A: Penetration time ≥ 30 minutes for least 6 chemicals from list.
TYPE B: Penetration time ≥ 30 minutes for least 3 chemicals from list.
TYPE C: Penetration time ≥ 10 minutes for least 1 chemicals from list

The pictogram for “chemical resistant” gloves must be accompanied by the code letters for the tested chemicals for type A and type B gloves. Type C gloves are without code letter.

PENETRATION TIME (PERMEATION) =

The time it takes for a chemical to penetrate from the outside to the inside of the glove material. Penetration test shall be performed at 23 ° C ± 1 ° C.

EN ISO374-4 and EN ISO374- 5

EN ISO 374-4
RESISTANCE AGAINST DEGRADATION FROM CHEMICALS
Degradation is a harmful change in one or more of the properties of a protective glove that occurs as a result of contact with a chemical. Indications for degradation can be delamination, discoloration, hardening, softening, dimensional changes, loss of breaking strength etc. It is determined by measuring the percentage change in the perforation resistance of the glove material after continuous contact for 1 hour between the outside and the provocation test substance. The results of the degradation test must appear in the information brochure for all three glove types.

EN ISO 374-5
PROTECTION AGAINST MICRO ORGANISMS

Microorganisms are defined in the standard as bacteria, fungi or viruses. In order to be able to indicate resistance to bacteria and fungi, the glove must meet the requirements for the test of resistance to penetration in accordance with standard DS / EN 374-2: 2014. If the glove meets the requirements of the test according to ISO 16604: 2004 (method B), it indicates that it is resistant to viruses, and the word “VIRUS” can be added under the pictogram of biological hazard.

EN 407
HEAT AND/OR FIREThe glove is tested against thermal hazards, heat and/or fire. The number indicates the result of the glove in the test. The following points are tested:

^{1 = lowest value}

EN 12477
WELDING

This standard is based on a series of tests from a number of other standards. The standard specifies minimum requirements for the results of these tests, to be tested and approved as a welding glove according to EN 12477. The standards that are tested according to are: EN 388 mechanical impact, EN 407 heat and/or fire. EN 367 heat transfer, EN 702 contact heat and EN 348 spray of molten metal. Welding gloves are approved in two types. Type A and type B. The requirements for type A are higher than type B in relation to the standards mentioned in most areas.
