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 movers during hydraulic fracturing.

Focused Electrostatic Collection of Aerosol Particles for Chemical Analysis by Spectroscopic Techniques

This CDC-developed technology is an aerosol preconcentration unit (APU) designed for use with spectroscopic detection techniques, including emission, Raman, or infrared spectroscopies. Most existing pulsed microplasma techniques, such as laser-induced breakdown, for aerosols rely mainly on filter-based collection and suffer from poor accuracy, precision, and detection limits and require long sample collection times.

Improved Acoustic Plethysmograph System for Noninvasive Measurement of Pulmonary Function

CDC researchers have developed a novel acoustic whole body plethysmograph (AWBP) that allows measurement of tidal volume in lab animals, independent of gas compression in the lung. This system provides particular advantages over the traditional whole body plethysmograph (WBP) when measuring model animals with increased gas compression due to increased airway resistance or increased acceleration in the breathing pattern.

Hearing Safety Devices: System for Monitoring Exposure to Impulse Noise

This CDC-developed technology entails a system for monitoring and assessing the risk of auditory damage from exposure to impulse noise, such as noise created by construction machinery and firearms. Noise dosimeters have been used extensively over the past two decades to document personal exposure to noise and assure workplaces comply with permissible noise exposure levels. However, due to older methods of calculating "noise dose," current noise dosimeters often inaccurately determine the risk of an impulse event.

Occupational Safety: Portable Exposure Assessment System for Prevention of Musculoskeletal Injury

CDC researchers have developed the Portable Exposure Assessment System (PEAS), a field-based, remotely deployed tool to monitor and provide early warning of working conditions that have a high likelihood of musculoskeletal injury. PEAS is a noninvasive, real-time, instrument-based system. Sensor technology simultaneously measures and collects data regarding the body loads and awkward postures imposed by package handling as well as driving-related, low-frequency vibrations.

Occupational Health: Wearable Kneel-Sit Support Device for Manual Labor and Heavy Industry Applications

This CDC-developed technology describes a novel ergonomic device that supports a portion of the worker's weight while kneeling, relieving the knee pressure and pain common to many manual labor occupations. Unfortunately, many of the devices that have been used in the past to relieve pressure on the knees are bulky, heavy, and of questionable durability.

Emergency Maritime Battery Charger

Boats and other watercrafts have emergency lifesaving equipment like strobe lamps to help rescuers locate individuals overboard in the event of a disaster. The battery life of the equipment is limited, so the amount of time rescuers have to find the victims is also limited. An emergency battery charger that can power emergency equipment is needed to remove this limitation.

Swing-Away Winch Cathead Guard

Shrimp boat operators use two trawl retrieval mechanisms mounted on the same winch frame. The main spools are used in the first operation; the shrimpers stand within inches of rotating cathead drums and guide incoming wire rope onto the main spools. Second, lazy lines are wrapped multiple times around each of the two spinning catheads (horizontal beams that raise and secure the anchor). Lastly, the guarding ends are pulled by the operators to cinch the rope to the rotating spool aiding trawl retrieval, but poses a hazard for operators to get entangled in the spinning cathead spools.

Direct Reading Detection Kits for Surface Contamination by Anti-Neoplastic (Anti-Cancer) Drugs

Anti-neoplastic drugs, also known as anti-cancer drugs or chemotherapy, are used in the treatment of many types of cancer. However, these drugs are harmful to healthy cells as well as the cancerous cells. Exposure of healthcare workers to anti-neoplastic drugs from contaminated surfaces and drug vials in hospitals and pharmacies is a continuing problem as the drugs can cause both acute and long-term effects. Although there are sensitive techniques to evaluate contamination, results from these tests take time and must be performed in a laboratory.
