Compact Solutions for Working from Home
Cities across the United States have been ordering shelter-in-place or stay-at-home orders to try to prevent the spread of the coronavirus. These measures have drastically changed the way people work requiring more workers to be able to work from home. Non-essential businesses and factories have been closing but employees still want to work to maintain… Learn More
Respiratory Hazards of Diacetyl and 2,3-pentanedione Exposure in the Coffee Roasting Industry
During coffee production of both flavored and unflavored coffee, production employees become exposed to dangerous VOCs resulting in irreversible lung damage (Ref. 1). The most hazardous VOCs released from flavorings and naturally from roasting coffee beans are diacetyl and 2,3-pentanedione. Exposure to even small amounts over time or large concentrations over a short period… Learn More
Laboratory Fume Hoods
Laboratory fume hoods provide operator and environmental protection from hazardous fumes, particulate, and other gases. Through inhalation, harmful fumes directly enter the blood stream and small particles may become embedded deep within the lungs (Ref. 1). A laboratory fume hood reduces exposure by containing the fumes and particulate dispersed during an experiment and a… Learn More
A discussion on 3D printers, UFP emission, and HEPA filtration
Nowadays, it is a common sight to see 3D printers in homes, schools, offices, labs, and workshops. The ability to quickly and economically print objects and prototypes make 3D printing one of the fastest-growing technologies today. The process of creating three-dimensional printed objects is actually quite interesting. The majority of commercially available 3D printers… Learn More
Mineral Dust: Geological Sample Preparation
Crushing, cutting, splitting, pulverizing and dividing. These are all common practices when preparing geological and mineral core samples for further testing and analysis. Breaking down a larger sample via these methods helps reduce volume and/or particle size, creates representative samples, and preps the sample for analyses like specific gravity or bulk density. There are several… Learn More
Respiratory protection from Schaudinn Fixative vapor
Schaudinn’s Fixative is a mercuric chloride-based fluid that is used to preserve the integrity of sample specimens in preparation for analysis. Once specimen fixation occurs, a stain is usually applied to the samples to help in the identification of specific microscopic organisms. While not a complete list, the fields of Parasitology, Cytology and Fecal Sampling… Learn More
Chloroform vapor control with carbon filtration
Chloroform is a by-product formed when chlorine disinfects water but also has many industrial uses (Delaware). French chemist, Jean-Baptiste Dumas, formally named and characterized chloroform in 1834. Since then, the chemical has been used for a variety of applications, including: • Solvent in the laboratory and pharmaceutical industries • Production of dyes • Bonding agent… Learn More
Reducing hexavalent chromium exposure with cleanable filter media
Sentry Air Systems is excited to publish our Industrial Hygiene Report on the Control of Welding Fume Particulates using Cleanable Filter Media as it relates to Hexavalent Chromium. Hexavalent chromium [Cr(VI)] is highly regulated by the Occupational Safety and Health Administration (OSHA) due to the fact that Cr(VI) fume is a known human carcinogen. Cr(VI)… Learn More
Workplace engineering control for sulphur dioxide, an acid gas
Sulphur dioxide [also called sulfur dioxide and SO2] is a colorless gas or liquid with a strong odor. It can be produced by the burning of coal, the source of most sulphur dioxide released into the environment.2 Because it can be inhaled in the general environment, much of the research on sulphur dioxide’s effect is… Learn More
