Silica Exposure Safety: Mini-baghouse Systems and Methods for Controlling Particulate Release from Large Sand Transfer Equipment

CDC/NIOSH scientists have developed an effective point-source control for silica-containing dusts that can be generated from machinery on sites where hydraulic fracturing is occurring. The CDC/NIOSH mini-baghouse retrofit assembly is a bolt-on control designed to contain silica-containing respirable dusts generated during refill operations of sand...

Ultrasonic in situ Respirator Seal-Leakage Detection with Real-time Feedback Capabilities

This CDC invention entails methods and apparatuses for in situ testing seal integrity and improved operation of respiratory masks (respirators). A variety of external factors, such as individual face shape, user environment, mask age and material used to construct the respirator, can lead to device malfunction and failure to sufficiently protect a...
