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.

Near Real-time, Low-cost, Hand-held Sensors for Measuring Elemental Concentration of Airborne Particles for Indoor or Outdoor Air Quality Monitoring

Airborne particles can have great impact on air quality, weather, and human health. In particular, long-term inhalation of toxic particulate matter in workplaces could pose a significant health risk. NIOSH scientists have developed a new, low-cost approach based on application of atmospheric radio frequency glow discharge (rf-GD) optical emission spectroscopy for near real-time measurement of elemental concentration in aerosols. The method involves collection of aerosol particles on an electrode tip in a coaxial microelectrode system, followed by excitation of the particles using rf-GD.

Respirator Protection Devices and Methods to Detect and Remove Toxic Gases from the Air - Cobinamide Encapsulated Silica-based Materials for Respirator Canisters

A respirator protects the wearer from inhaling dangerous substances, such as chemicals and infectious particles. CDC developed devices and methods to detect and remove chemicals such as hydrogen cyanide, cyanogen, hydrogen sulfide, nitrite, and nitric oxide from the air for those wearing respirators. Cobinamide (a Vitamin B12 analog with a high affinity to cyanide) molecules are immobilized within a silica matrix that allows for the infiltration and containment of gaseous chemicals.

Adjustable Barricade Safety Rail System and Roof Bracket Assembly to Prevent Worker Falls

Falls are the leading cause of death in construction. In 2016, there were 370 fatal falls out of 991 construction fatalities (Bureau of Labor Statistics, Census of Fatal Occupational Injuries data). These deaths are preventable. According to the Occupational Safety and Health Administration, employers must set up the workplace to prevent employees from falling from overhead platforms, elevated work stations, or into holes in the floor and walls.

Wipes and Methods for Removal of Lead and Other Metal Contamination from Surfaces

Exposure to lead (Pb) has long posed serious health risks. Ingestion of lead from skin exposure can adversely impact every organ in the body; the kidneys, blood, nervous, and reproductive systems are most affected. Washing skin with soap and water is not sufficient to remove lead residues. To prevent adverse impacts from Pb exposure, exposed individuals need cleaning methods that will effectively remove Pb ions from the skin to less than the limit of identification (i.e., 10 µg or less).

Handwipe Disclosing Method for Detecting the Presence of Lead

Lead (Pb) exposure can cause serious health concerns including abdominal pain, headaches, loss of appetite, memory loss, weakness, and other symptoms. Lead residues on human skin, especially on the hands of workers can be a significant health risk since such residues may be ingested during normal activities (e.g. eating, drinking, and smoking). A key component to reducing lead exposure is being able to identify areas of lead contamination.

New Insect Sf9-ET Cell Line for Determining Baculovirus Titers

The baculovirus-based protein expression system has gained increased prominence as a method for expressing recombinant proteins that are used in a wide range of biomedical applications. An important step in the use of this system is the ability to determine the virus infectious titer, i.e., the number of active baculovirus particles produced during an infection of the insect host cell.

Topical Sodium Nitrate Ointment for Sickle Cell Disease

Chronic leg ulcers are a debilitating vasculopathic complication for some patients with sickle cell disease (SCD). Prevalence of leg ulcers varies based on age and geographic location; about 5-10% of all SCD patients may suffer leg ulcers. These leg ulcers are painful, result in infections, hospitalization, disability, and negatively impact the patient’s social and psychological wellbeing on an ongoing basis.
