![]() Uses replaceable chemical cartridges or canisters to remove the contaminant.It is important to know what hazards you will face in order to be certain you are choosing the right filters/cartridges. There are cartridges available that protect against more than one hazard, but there is no "all-inone" cartridge that protects against all substances. Selecting the proper filter can be a complicated process. Gas masks are effective only if used with the correct cartridge or filter (these terms are often used interchangeably) for a particular biological or chemical substance. The cartridge may also have a filter to remove particles. This respirator includes a facepiece or mask, and a cartridge or canister. Examples: filtering facepiece or elastomeric respirator.Ĭhemical Cartridge/Gas Mask Respirator: Gas masks are also known as "air-purifying respirators" because they filter or clean chemical gases out of the air as you breathe.Must be replaced when they become discolored, damaged, or clogged.Are usually disposable dust masks or respirators with disposable filters.Particulate respirators are "airpurifying respirators" because they clean particles out of the air as you breathe. The commonly known "N-95" filtering facepiece respirator or "dust mask" is one type of particulate respirator, often used in hospitals to protect against infectious agents. They do not protect against chemicals, gases, or vapors, and are intended only for low hazard levels. These respirators only protect against particles (e.g., dust). Particulate Respirators: Particulate respirators are the simplest, least expensive, and least protective of the respirator types available. Respirators work by either filtering particles from the air, chemically cleaning (purifying) the air, or supplying clean air from an outside source. There are several different types of respirators, as described below. ![]() This assessment should be done by experienced safety personnel or by an industrial hygienist. The identity of the hazard and its airborne concentrations need to be determined before choosing a respirator. Selecting the right respirator requires an assessment of all the workplace operations, processes or environments that may create a respiratory hazard. Respirators are among the most important pieces of protective equipment for working in hazardous environments. ![]() What is a respirator?Ī respirator is a device that protects you from inhaling dangerous substances, such as chemicals and infectious particles. The guidance provides information on what respirators are, how they work, and what is needed for a respirator to provide protection. Never clean the filters with compressed air or compressed water.The information in this bulletin will provide basic information to workers and employers who may find themselves using respiratory protection for the first time. ![]() The filter must not be exposed to shocks, dangerous gases or vapors.ĭo not attempt to regenerate filters. Temperatures can range between -5 ° C and 30 ° C with a relative humidity of up to 80%. The filter should be stored in a dark, cool, dust-free environment that is regularly ventilated and without sudden temperature changes. ![]()
