What are the contraindications for the use of filtering and absorbing equipment?

Filtering-absorbing respiratory protective equipment must not be used when:

• in the atmosphere of the working environment, 7% deficiency (less than 1 volume)
• from card-based sources, no odor and / or taste or origin, no odor and / or taste origin, or perceptible origin, higher than TLV value;
• work for small, unventilated facilities
• In the statute of the equipment in the form of settings in working condition it is large that it does not ensure safe use;
• Steam and gas turbine in the atmosphere of the working environment is greater than 1 vol;
• unidentified chemicals are present;
• in the conditions of the working environment, extreme temperature conditions occur;
• a platform of "tightly" stubble filtering equipment with or atypical, deformed face.

To ensure quality to work in technical conditions and work at work. Offers with a mask have their own specification:

Filtration efficiency - they have value, users have high values.

       Filtration class Max. Efficiency Type

       aerosol filtration preparations

       P1 4 X TLV 80% dust, smoke, fog

       P2 10 X TLV 94% dust, smoke, fog

       P3 30 X TLV 99% dust, smoke, fog

Class respirators: In accordance with the requirements of EN 149: 2001, P1, P2, P3, they are tested with sodium chloride aerosol and paraffin oil mist. Passing this test while meeting the requirements for high product quality.

Typical Application:

• P1 class half masks - agriculture, food industry, quarries, cement plants, construction, soft wood
• Class P2 half masks - industrial, chemical, chemical, metallurgical, create the possibility of creating fire
• P3 class respirators - processes and soldering

Dust absorption:

The hygiene mask should be suitable for dust by increasing breathing resistance.

Comfort of use: Dependent, among others on the quality of the filter materials used, culture of use, technology, progress and ease of handling.

Adjusting to the user's face: Good pressure on the nose clip and the adhesion of the surface that touches the face are important here. Failure to tighten the half-mask leads to the lack of its filtration system.

Look after: Dependent accidents on the occasion of a game opportunity opportunity (called Absorb with the progress of the magnification and in the coals that has been removed from the procedure.
