    The 3M™ Organic Vapor Service Life Indicator Cartridge i helps provide organic vapor protection in a variety of environments. The cartridge may be used for vapor concentrations up to 10 times the Permissible Exposure Limit (PEL) with half facepieces or 50 times PEL with quantitatively fit . End of service life for gas and vapor cartridges is determined by either: •an end-of-service-life indicator (ESLI) certified by NIOSH, or •the employer must implement a change schedule to ensure cartridges are changed before the end of their service life.

    A respirator cartridge or canister is a container that cleans pollution from air. People working in polluted atmospheres use respirators for health preservation. If the air in the workplace is polluted with noxious gases, but contains sufficient oxygen (>% in US; >18% in RF) they often use air-purifying respirators (APR). These respirators provide users breathable air by removing pollution. A typical organic vapor respirator cartridge is a metal or plastic case containing from 25 to 40 grams of sorption media such as activated charcoal or certain resins. The service life of the cartridge varies based, among other variables, on the carbon weight and molecular weight of the vapor and the cartridge media, the concentration of vapor.

Development of a prototype service-life indicator for organic vapor respirators by Arthur D. Little, Inc. Download PDF EPUB FB2

A NIOSH sponsored effort to develop and test a prototype service life indicator for organic vapor air purifying respirators is reported. A series of performance requirements for an end of service life indicator (ESLI) was developed which addressed indicator characteristics, specificity, reliability, respirator fit, weight, impairment of vision, durability, breathing resistance, temperature and.

A prototype end of service-life indicator for organic vapor air purifying respirators was developed and tested under laboratory conditions. A metal oxide gas sensor (MOGS) was incorporated in the unit.

The detector and indicator light are designed to fit on the face mask of a chemical cartridge respirator, and the associated electronics and. Development of a prototype service-life indicator for organic vapor respirators.

A prototype device for indicating the end of service life of respirator cartridges was developed. The device consisted of a microsensor embedded in the charcoal bed of the cartridge that was electrically connected to a small low power producing module mounted on the face mask.

A piece of filter paper containing aquohydroxocobinamide [OH(H 2 O)Cbi] was placed on the end of a bifurcated optical fiber, and the reflectance spectrum of the OH(H 2 O)Cbi was monitored during exposure to ppm hydrogen sulfide gas (NIOSH recommended exposure limit).Cited by: 2.

ST. PAUL, Minn(BUSINESS WIRE)--Using a respirator cartridge beyond its service life can endanger workers and lead to regulatory violations. 3M has launched a new line of organic vapor respirator cartridges with 3M™ Service Life Indicator technology, an end-of-service-life-indicator (ESLI) that, when used in appropriate environments, visually shows when users should change cartridges.

How an Organic Vapor Respirator Cartridge Works Factors that influence service life: • Exposure concentration • Temperature • Humidity (water vapor takes up space in carbon pores) • Breathing rate Activated carbon adsorbs organic vapors on molecular level. Unfiltered organic vapors are drawn into the cartridge.

Service life continues. Prototype end of service life indicator devices were evaluated on a respirator cartridge test system. The detector system for the prototype devices was based on a metal oxide combustible gas sensor.

The duty cycle in the prototype and the effects of humidity on the sensor could allow exposure of the user to vapor concentrations greater than. What is claimed is: 1. An effective-end-of-service-life indicator system for a filter cartridge for a respirator for organic vapor, comprising: a sensor, located within the cartridge, that fluoresces visible light upon exposure to UV light; a UV lamp operable to emit UV light; and a visible light detector operable to detect the intensity level of visible light; wherein: the UV lamp is directed.

How the 3M Service Life Indicator works. 3MTM Organic Vapor Cartridges i and i contain the 3M Service Life Indicator, a visual ESLI for certain organic vapors and exposure levels. The ESLI is located inside the cartridge, next to the activated carbon.

As organic vapors travel through the cartridge, they are also adsorbed into the ESLI. 3M™ Novec™ Contact Cleaner/Lubricant, oz 3M™ Cubitron™ ll Cloth Belt A. out of 5 stars. Festool Compressed Air Orbital Sander LRS out of 5 stars.
