    Assigned Protection Factors

    Definition: APF is an acronym for Assigned Protection Factor.
    APF is the workplace level of respiratory protection that a respirator or class of respirators is expected to provide to employees when the employer implements a continuing, effective respiratory protection program.


    More Information:
    An APF of 1,000 means the respirator is approved for concentrations up to 1,000 times the Permissable Exposure Limit for the respiratory hazard.

    Air Sources

    Supplied Air Respirators (SARs) require a Grade D Breathing Air source. This source may be provided in one of three ways: 

    1. Via oil-less Ambient Air Pump, such as a Bullard Free Air® Pump, which draws in fresh air and delivers it to the respirator without additional filtration or CO monitoring. It is critical that the intake for this type of pump be located in a known clean air location.
    2. Via Shop Air Compressor with after market filtration and monitoring such as Bullard's Clean Air Box Series of 3-stage filtration with integrated CO Monitoring.
    3. Via a Breathing Air Compressor with factory installed filtration and CO monitoring.


    Powered Air Purifying Respirators (PAPRs) can be thought of as a hose-free air source that one wears on his/her own waist. In the simplest of terms, a PAPR is a filter and a fan that draws the air into the filter and/or chemical cartridge and, purifying it, and delivering it to the respriator wearer. NIOSH tests and approves PAPRs specific to the hazard capability of the filter cartridge. It is crticial that the correct filter cartridge is selected and used for the respriatory hazard in question.


    Cooling vs. Mobility
     One thing to consider in making the choice between a PAPR or SAR is the importance of cooling vs. mobility. SARs can often be equipped with vortex cool tubes to cool the incoming air by up to 30 degrees F but the worker will be tethered by the air supply hose. The high volume of air flow that the PAPRs provide makes them significantly more comfortable than negative pressure air purifying respiratos (APRs) but existing technology will not allow for the use of vortex cool tubes. However, the greater mobility without the air supply hose tether is often a determing factor in the respirator selection process.

    Product Features

    Intrinsic Safety is a protection method employed in potentially explosive atmospheres. Certificate IS tools are designed to prevent the release of sufficient energy to cause ignition of flammable material. IS standards apply to all equipment that can create one or more of a range of defined potential explosion sources: Electrical Sparks, Electrical Arcs, Flames, Hot Surfaces, Static Electricity, Electromagnetic Radiation, Chemical Reactions, Mechanical Impact, Mechanical Friction, Compression Ignition, Acoustic Energy, Ionizing Radiation.


    Fit Testing is required by OSHA (29 CFR 1910.134) for tight-fitting respirators. This testing is to be prior to the initial use of the respirator, whenever a different respirator facepiece (size, style, model or make) is used, and at least annually thereafter. Additional fit tests are necessary whenever a change in the employee's physical condition is observed that could affect respirator fit including: facial scarring, dental changes, cosmetic surgery, or obvious body weight change. However, loose fitting style respirators such as Bullard's 20LF, CC20, RT, GR50, and 88VX Series do not require fit testing.

    Pharmaceutical Manufacturing

    Pharmaceutical Manufacturing

    Since the development of the first Tychem® disposable hood-style respirator (CC20) for Eli Lilly in 1983, Bullard has long been a leader in respiratory protection for the pharmaceutical manufacturing industry. No matter whether it is Pilot Plant, Solid Dosage, API Handling, or Granulation, Bullard has the product and expertise to meet the needs of the pharma industry.

    Laboratory Sciences

    Laboratory Sciences

    Conducting Lab Animal Research? Developing a new vaccine? Working in a BSL-3 facility? Several prominent labs have chosen Bullard's line of Supplied Air Respirators (SAR) and Powered Air Purifying Respirators (PAPR) to help prevent their workers from contracting Lab Animal Allergy (LAA) and/or from being exposed to deadly viruses or toxic chemicals while performing research.

    Painting

    Painting

    Organic vapors and isocyanates are just two of the hazards that require high levels of respiratory protection in many painting operations. Bullard has a long history of providing Air Quality products to ensure Grade D Breathing Air and Respiratory Protection products to ensure worker safety for the painting industry. In addition, Bullard offers a wide variety of integrated cooling options to increase worker comfort and productivity.

    Abrasive Blasting

    Abrasive Blasting

    Beginning In the 1930s, with the development of one of the first abrasive blasting respirators as part of the Golden Gate Bridge construction project, Bullard has been the leader in protecting those who repair and maintain bridges, ships, tanks, railcars, and virtually anything that requires surface preparation. Choose from CO Monitors or Free Air Pumps for Grade D Compliance and NIOSH approved Supplied Air Respirators with integrated cooling options for OSHA compliance.

    Confined Space

    Confined Space

    According to OSHA Regulations 29 CFR 1910.146a and 29 CFR 1910.134, Permit-Required Confined Space work operations that can potentially be IDLH, such as in the wastewater and utility industries, require the use of a full facepiece pressure demand SCBA or a combination full facepiece pressure demand supplied-air respirator (SAR) with auxiliary self-contained air supply. The Bullard Spectrum Series provides protection and compliance for these types of applications.

    Spray Foam

    Spray Foam

    Bullard can protect Spray Foam applicators from the respiratory and vision hazards caused by the isocyanates in the foam chemicals. The low profile designs of Bullard respirators allow for maximum freedom of movement in tight spaces such as attics and crawl spaces. Bullard Free Air Pumps offer compact, portable breathing air solutions for mobile jobsite operations.

    Abatement

    Abatement

    Bullard can protect Mold and Asbestos abatement workers from the respiratory and vision hazards encountered in such operations. The low profile designs of Bullard respirators allow for maximum freedom of movement in tight spaces. Bullard Free Air Pumps offer compact, portable breathing air solutions for mobile jobsite operations.

    Powder Coating

    Powder Coating

    Choose a Powered Air Purifying Respirator (PAPR) with HEPA filtration for maximum mobility or a Supplied Air Respirator (SAR) with a vortex action cooling tube for maximum comfort and a multi-stage filtration system with CO monitoring for Grade D compliance. Regardless of configuration, Bullard respirators and air quality products are a great fit for powder coating operations.

    Grinding

    Grinding

    Particles from grinding wheels can be small enough to constitute a respiratory hazard. Sparks from grinding chips can melt or ignite lesser forms of PPE. Shop operations often require the use of hard hats. Fabrication and repair jobs are often hot leaving the workers searching for relief. Bullard Grinding Hood style respirators provide integrated solutions for all of these issues.

    Healthcare

    Healthcare

    The possibility of mass infections among health care workers is increasing with SARs, TB, Flu, and other airborne communicable diseases. A PAPR with loose fitting facepiece provides these critical community service providers 150% more protection than traditional N95 mask-style respirators while eliminating the need for expensive fit testing. New technology has made PAPRs quieter and lighter than ever while the loose fitting facepiece design allows for stethoscope use.

    Welding

    Welding

    Stricter OSHA Permissable Exposure Limits (PELs) for the airborne hazards generated by welding operations are driving the need for higher respiratory protection. Bullard welding respirators offer 400% more protection than traditional N95 mask-style respirators while maintaining a low profile to accommodate the welder's helmet of choice. Bullard offers both Supplied Air (SAR) and Powered Air Purifying Respirator (PAPR) choices.
