Types of Respirators This guide provides a brief overview. Please review the following for more detailed information: • OSHA • NIOSH There are a variety of different types of respirators that are typically categorized as either air-purifying or atmosphere-supplying, with some being further sub-categorized as: • Positive or negative-pressure • Tight or loose-fitting • Continuous-supply, demand or pressure-demand • Half or full-face What is important is to make sure the appropriate one is being used given the: • Type and concentration of airborne contaminants in question. • Comfort of the user. The more uncomfortable it is, the less likely it will be used, or used properly. Be sure to also consider heat-stress issues associated with the type of respirator selected for use.
Air-purifying Respirators (APR) APRs work by removing gas, vapor and particulate contaminants from the air through the use of filters, cartridges or canisters. There is no one filter or cartridge/canister that removes all contaminants, so it is important to use the right one for the air contaminants of concern. For example: in an organic solvent-based paint spray operation you would probably need a combination of a particulate/aerosol pre-filter and an organic vapor cartridge. All filters/cartridges have a NIOSH approval label and are color-coded. Examples of air-purifying respirators include: • Disposable filtering facepiece respirators (dust masks) used for airborne particulates

Are respirators necessary to protect the health of the employees (or required by the employer)? Yes Establish and implement a written respirator program with the following procedural elements: • Selection of Respirators • Medical Evaluation • Fit Testing of Tight-fitting Respirators • Proper Respirator Use • Maintenance and Care of Respirators • Breathing Air Quality and Supply • Employee Training and Information • Program Effectiveness Evaluation • Recordkeeping
This saying that is against OSHA and here in California CalOSHA regulations to give untrained unmedically monitored and unsupervised school children N95 respirators
It’s a long overdue start but without explaining the purpose and effectiveness of the various filter elements the rest is pretty much useless. Been doing respiratory protection stuff from dozens of different angles, for at least six decades, and have most of the common equipment right here in the shop. It is so incredibly boring to always hear just pieces of the basic methods/problems/equipment spouted by people who obviously never read a book on the subject.
My business requires respirators for certain tasks. You can not just hand out a respirator including the N95 without following the regulatory guidelines. The State of California is violating its own rules
