Half Face Mask Dust and Airline Respirators
Overview

Respiratory protection is a necessary adjunct in any industry where dusty or toxic atmosphere is met within the working atmosphere. Even in the plants having well designed ventilation systems and confinement systems, use of respiratory protective equipment may become necessary under certain conditions to protect workers from inhalation hazards. The degree of respiratory protection needed can vary over a wide range and thus different types of respirators have come to be in use. Bhabha Atomic Research Centre has developed half face mask dust and airline respirators to protect from inhalation of atmospheric contaminants such as radioactive particulates, bacterial and viral loaded particles, dusts, fumes & vapors (using chemical cartridges), smoke etc.

Bhabha Atomic Research Centre has developed half face mask dust and airline respirators to protect workers from inhalation of atmospheric contaminants such as radioactive particulates, bacterial and viral loaded particles, dusts, fumes & vapors (using combination cartridges), smoke etc.

Half Face Mask Dust Respirator

This is an air-purifying respirator having half-face mask to cover nose and mouth. The dust respirator, a half-face mask fitted with HEPA filter cartridges (P100, P3 or FFP3 type) provides respiratory protection of the personnel against inhalation of atmospheric contaminants such as radioactive particulates, bacterial and viral loaded particles, dusts, fumes & vapors (using combination cartridges), smoke etc.. The mask can also be fitted with a pair of combination type filter cartridges to remove organic & iodine vapors in addition to particulates from the working atmosphere. The newly modified face piece of the mask made up of silicon elastomer has soft internally rolled periphery, which assures comfortable and airtight fit on persons of widely varying facial contours and sizes. These Respirators are normally fitted with a pair of high efficiency filter cartridges having minimum efficiency of 99.97% against 0.3-micron size particles.

Half Face Mask Airline Respirator

Airline respirator is a continuous flow air supplying respirator. It has a half mask face piece to which clean and filtered air is supplied through a small diameter air hose. In this type of respirator, a set amount of air is continuously fed to the face piece. This respirator can be used in an atmosphere contaminated with gaseous and /or particulate matter. Positive pressure inside the face piece gives very little possibility for outside contaminated air to leak in. Continuous flow of fresh and cool air to the face piece provides cooling to the face of the wearer. This type of respirator can be worn for long duration without any discomfort.

These Respirators are normally fitted with a pair of high efficiency filter cartridges having minimum efficiency of 99.97% against 0.3-micron size particles. This respirator can also be fitted with a pair of combination (Impregnated charcoal + HEPA) filter cartridges to remove organic and iodine vapors in addition to particulates from breathing atmosphere. These respirators are normally used in plants where toxic particulates/radionuclides are likely to be present in the working environment where there is a requirement for highly efficient respiratory protective equipment with filters having particulate removal efficiency in the order of 99.97% or more for 0.3 micron size particles. Also these respirators are applicable in atmospheres where protection against particulates like radioactive particulates, fumes and dusts generated during welding operations, beryllium dust, silica dust generated during mining operations, civil construction work etc.

Half Face Mask Airline Respirators

This is a continuous flow air-supplied respirator. It has a half-face mask to which respirable air at the rate of 120 l/min is continuously fed by means of an air-hose. Positive pressure inside the face-piece gives very little possibility for outside contaminated atmosphere air to leak in. These respirators are mainly used in conjunction with plastic suits to provide air for breathing and to protect the personnel against dusts, vapors and gases. Plastic suits are used to prevent skin contamination in the nuclear facilities. These equipment can also be used in various other industries such as chemical, food processing, agriculture, petroleum, pharmaceutical or mechanical industries. The effectiveness of a respirator depends on many factors such as the integrity of the face seal, the filtration capability of the selected canister or filter medium etc.

INFRASTRUCTURE REQUIREMENTS

Testing Facility

Various facilities and equipment are required for the testing of components. Equipment like rubber hardness tester and a compressor for checking the hardness & leakage due to rubber components respectively are essential. A respirator jig has to be fabricated for testing the leakage in exhalation valves, dust respirators and also to determine the pressure drop/ resistance of the exhalation valve as well as filter cartridges. For inward leakage testing of the respirator, a leakage testing setup by leak meter is required. Visual inspection of all the rubber and plastic components under good light condition is to be carried out for smoothness, blowholes, cracks, good workmanship etc. A portable compressor and a test unit (technology of which will be provided by BARC) to test the leakage in respirators and pressure drop of filter cartridges, exhalation valves and other components are required.

INFRASTRUCTURAL FACILITIES

The firm should have:

  1. A well maintained light duty workshop to fabricate metal components required for the production of respirators, servicing of moulds, etc.
  2. A hand / semi-automatic plastic molding machine to fabricate plastic components
  3. A large size hot press (60cm X 60cm) for molding rubber components. The moulds required for face-piece (nose-cup), corrugated rubber hose; exhalation valve, cartridge holder etc. either can be made by outsourcing or fabricated in the workshop as per drawings

Space Required

  • A covered space for workshop and molding facilities would be about 35 sq. meters and that for assembly and testing of finished products would be an air-conditioned dust free space of 30 sq. meters for production of 2000 dust respirators and 1000 airline respirators annually.

Power requirement

  • Three phase power connection.

MANPOWER

For the production of 2000 dust respirators and 1000 airline respirators per annum, the man- power requirement is as follows:
