The choice and use of respirators in developed countries is regulated by national legislation. To ensure that employers choose respirators correctly, and perform high-quality respiratory protection programs, various guides and textbooks have been developed:
Respiratory protective equipment (RPE), also called protective breathing equipment (PBE) in the US, [1] is a form of personal protective equipment designed to protect the wearer from a variety of airborne hazards in the form of a gas, fume, mist, dust or vapour. Respirators filter the air to remove harmful particles and alongside the breathing ...
PAPRs can provide an assigned protection factor between 25 and 1000 depending on the type, as compared to an N95 mask's assigned protection factor of 10. [2] [3] When comparing various makes and models of PAPR, the supporting documentation from each of the respective manufacturers should be consulted in order to confirm the APF value of each ...
Polish Au-2 escape respirator. Escape breathing apparatus, also called escape respirators, escape sets, self-rescuer masks, emergency life saving apparatus (ELSA), emergency escape breathing devices (EEBD), and Respiratory Protective Smoke Escape Devices (RPED), [1] [2] are portable breathing apparatus that provide the wearer with respiratory protection for a limited period, intended for ...
Surgical masks are designed to protect against splashes and sprays, [16] but do not provide complete respiratory protection from germs and other contaminants because of the loose fit between the surface of the face mask and the face. [17] Surgical masks are regulated by various national standards to have high bacterial filtration efficiency (BFE).
The respiratory protective devices (RPD) can protect workers only if their protective properties are adequate to the conditions in the workplace.Therefore, specialists have developed criteria for the selection of proper, adequate respirators, including the Assigned Protection Factors (APF) - the decrease of the concentration of harmful substances in the inhaled air, which (is expected) to be ...
The user respiratory interface is the delivery system by which the breathing apparatus guides the breathing gas flow to and from the user. Some form of facepiece, hood or helmet is usual, but for some medical interventions an invasive method may be necessary.
An open circuit SCBA typically has three main components: a high-pressure gas storage cylinder, (e.g., 2,216 to 5,500 psi (15,280 to 37,920 kPa), about 150 to 374 atmospheres), a pressure regulator, and a respiratory interface, which may be a mouthpiece, half mask or full-face mask, assembled and mounted on a framed carrying harness.
