It emphasizes information-sharing, developing educational materials - including a video on struck-by injuries - and raising awareness about industry hazards and leading causes of occupational fatalities. (scienceblogs.com)

Medical waste includes anything that comes into contact with bodily fluids or infectious materials, such as needles, syringes, and medical gloves. (tkgservices.com)

Routine air sampling, appropriate screening for radioactive materials, and maintaining a tidy work environment are crucial to protecting employees. (cari-acir.org)
The term background is also sometimes used in this report to indicate radioactive elements present in the environment that are not a direct result of SRS activities (e.g. atmospheric weapons testing fallout, see definition for fallout ). (cdc.gov)
The containment of sources of alpha particles within protective enclosures to prevent their release into the environment forms the basis of risk management. (thincb2b.com)
Immobilization of the radioactive material prevents release of those materials into the environment. (justia.com)
Experimental releases may include females and males and evaluation must consider their effects based on the number released, their genotype and phenotype, the environment into which they are released, and postrelease collection activities. (cdc.gov)

Chlorine and other noxious chemical gas releases from intact, closed-valved containers at metal recycling facilities are preventable. (cdc.gov)

The first presentation by the Gesellschaft für Anlagen- und Reaktorsicherheit (GRS) focused on the interaction between the pre- and post‑closure phases of geological repositories in terms of the features, events, and processes (FEP) analysis and derivation of hazards. (oecd-nea.org)

The concern is the possible inhalation and/or ingestion of scale particles contaminated with radium-226 and possibly other radioactive material that may become airborne during welding, cutting or reaming of pipe containing the radioactive scale. (osha.gov)

Our initial experience with our license renewal process, by almost all measures, appears to have been successful,' commissioner Greta Joy Dicus told the 16th International Conference on Structural Mechanics in Reactor Technology, held in August in Washington, D.C. (ieee.org)

Well-planned radiation safety-together with a radiation protection program-helps employers create a hazard-free zone where the optimal prevention measures are enforced. (safetystratus.com)

The product stream of enriched UF 6 obtained is then converted to the form of UO 2 for further processing to nuclear fuel assemblies. (ratical.org)

Additionally, metal recycling facilities could consider strategically placed escape gas masks in the case of unintentional chemical gas releases. (cdc.gov)
Metal recycling facilities should not accept containers for processing unless they are open without a valve. (cdc.gov)
Similar administrative controls to identify intact, closed-valved containers brought to metal recycling facilities before processing begins may further protect employees. (cdc.gov)
According to Esther Harlander, Head of ERA, grant funds allocated by donors have already facilitated the closure of mine openings, the demolition of derelict uranium ore processing facilities, and the recultivation of waste dumps and tailings in multiple locations across Central Asia. (ebrd.com)
The NRC only names one item on the "pro" side of the ledger for this option, which is that the agency is already in the process of updating regulations for utilization facilities. (forbes.com)

[ 1 ] The main challenge was adapting the existing models, whose primary focus was containing a hazardous material release, to one that reflected the chaos of a large-scale disaster involving a large number of affected individuals. (medscape.com)
