What You Need to Know About Photo Ionization PID Gas Detectors

by

Photo ionization gas detectors work by detecting changes in the molecular structure of a gas. Photo ionization gas detectors use ultraviolet light to ionize any molecule in the air into a charged ion. These charged ions are then detected by a photo tube or ion sensitive electronics. Photo ionization gas detectors are the best gas … Read more

Respirator Fit Testing

by

Respirator Fit Testing Respirator fit testing consists of several exercises designed to stress the respirator/face seal during which the test subject wears the respirator to be tested, and the ratio of the challenge agent concentration inside the mask to the ambient concentration is measured. This Ratio is the Fit Factor. In the CNC method ambient … Read more

Chemical Hazard of the Month

by

Chemical Hazard of the Month n-Hexane C6H14 Hexanes are significant constituents of gasoline. They are all colorless liquids, odorless when pure, with boiling points between 50 and 70°C (122 and 158°F). They are widely used as cheap, relatively safe, largely unreactive, and easily evaporated non-polar solvents. In industry, hexanes are used in the formulation of … Read more
