L'explication/l'anotation:To protect respiratory organ from acid gas harmful substances (fluoride or hydrogen chloride, chlorine, sulphureous gas, para of sulphur, acetic acid etc ) in case of their concentrations into the air to 15 maximum permissible concentrations.
La description détaillée de marque:Device:
the respirator represents ïîãëîùàþùå-ôèëüòðóþùóþ in the form of cone the half-mask from polymer fibrous chemically active material with exhalation valve, aluminium nasal plate and elastic tapes of headband.
the technical characteristics
the respirator mass,. To 20 initial resistances âäîõó, item. To 30
restriction of field of view, not more, %. 12 dynamic sorption capacities of respirator - 28 mM of harmful substance.
application and maintenance:
the respirator are donning on person, the aluminium plate pressed in accordance with the form of bridge of the nose so as the respirator densely ïðèëåãàë to person without sensation of pain, squeeze and inleakage of air on page of obturation.
upon completion of the works, if required, the respirator is subject to purification and or regenerations, and then - reuse. The material withstand 30 regeneration cycles. The purification carry out by hand in solution of powder, respirator regeneration of mark in - in 5-7 % soda solution. The solution temperature shall not out-top +45 S. squash only light pressure of palm, without twisting. Drying at a temperature of not higher than 60 with ðàñïðàâëåííîì kind.
the development time of respirators is specified:
- on gases - by odour under mask,
- on dust (àýðîçîëÿì) - on breathing resistance.
range of applicability and condition of respirators regeneration:
from what noxious gases and steams protects - the hydrogen fluoride, the sulfur dioxide, the hydrogen chloride, the acetic acid etc. acid gases. Refreshing water solution - sodium carbonate, 5-7%.
attention! The respirators impossible to apply for protection against specially hazardous gases with narrow band of acute action, as well as in irrespirable C atmosphere oxygen content lower 18% on. |
