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

diacetyl coffee production

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 of… Learn More

Laboratory Fume Hoods

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 powerful… 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

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 Reagent in organic synthesis Anesthetic Refrigerant Production of tetrafluoroethylene (TFE) which is used to make polytetrafluoroethylene (PTFE) – a primary… 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

Fluorine: Hazardous effects from a single atom

Fluorine [floo r-een], commonly misspelled as “flourine”, is a poisonous pale yellow odorous element found in the Halogen Group of elements of the periodic table. Fluorine is one of the most reactive elements known; it reacts violently with water yielding flammable O2 and corrosive and toxic hydrofluoric acid. Periodic Table of Elements: Fluorine Hydrofluoric acid… Learn More
