SU-CD-PinS Room/Hall E-00: HAZMAT Training for the Medical Physicist - Part I

Medical Physicists are frequently involved in shipping radioactive materials or supervising those who do. Current U.S. Department of Transportation Hazardous Material Regulations, 49 CFR Parts 171 - 185, require hazmat employees to have documented training specified in 49 CFR 172 Subpart H. A hazmat employee is defined as an individual who: (1) loads, unloads or handles hazardous material; (2) manufactures, tests, reconditions, repairs, modifies, marks or otherwise represents containers, drums or packagings as qualified for use in the transportation of hazardous materials; (3) prepares hazardous materials for transportation; (4) is responsible for safety of transporting hazardous materials; or (5) operates a vehicle used to transport hazardous materials. Recurrent training is required at least once every three years. (The IATA two-year training interval is not applicable and is generally misunderstood.) FAA has escalated inspection and enforcement. Facilities who ship radiopharmaceuticals to other laboratories, return radiopharmaceuticals or radioactive sources to suppliers, or otherwise ship radioactive materials have been cited for failure to provide and document the required training. The interrelationship of transportation regulations, 49 CFR, IATA, ICAO and other transportation regulations, which are frequently misunderstood, will be explained. The course will cover typical shipments by air and highway which are encountered in a medical institution. Items such as fissile materials, highway route controlled quantities, rail shipments, vessel shipments and such will be omitted; although specific questions may be addressed. A major objective of the course is to present the process of shipping radioactive material in a sequential and logical fashion. How radioactive materials for transportation purposes are defined by activity concentrations for exempt materials and activity limits for exempt consignments will be explained. Radioactive material shipments of excepted packages and Type A packages will be emphasized. The program is designed to meet the function specific DOT training requirements for shippers of medical radioactive materials. General awareness training and security awareness training can be obtained from two free DOT training CDs. Safety training and security awareness training is generally satisfied by the training required under the institution’s radioactive material license. For shippers of radioactive Yellow III labeled packages an in-depth written security plan and training are no longer required as of April 8, 2010. In general almost all shippers of medical radioactive material are now not required to have an in-depth security plan. Contents of general awareness training, security awareness training and in-depth security plans will be briefly outlined. It is the hazmat employer’s responsibility to ensure that each hazmat employee is properly trained. No third party can fulfill that requirement. It is the hazmat employer’s responsibility to determine the degree to which this course meets the employer’s requirements, including contents of the course and the examination. Participants will gain sufficient knowledge to prepare hazmat training programs for others in their institutions. A handout will be posted which should be printed out and brought to the course for reference during the presentation. The handout will also satisfy part of the training documentation required by DOT. A feature handout section is a composite table which provides A1, A2, RQ, Exempt Concentration, and Exempt Consignment values in a single table in both Becquerel and Curie units. Course attendance will be certified through the AAPM CEU documentation system. Learning Objectives: Understand the regulatory requirements for shipping radioactive materials. Understand the regulatory requirements for training of hazmat employees. Comprehend how to classify, package, mark, label, document, placard, and transport radioactive materials.

HAZMAT. I. The evolution of far-UV and near-UV emission from early M stars

The spectral energy distribution, variability, and evolution of the high-energy radiation from an M dwarf planet host is crucial in understanding the planet's atmospheric evolution and habitability and in interpreting the planet's spectrum. The star's extreme-UV (EUV), far-UV (FUV), and near-UV (NUV) emission can chemically modify, ionize, and erode the atmosphere over time. This makes determining the lifetime exposure of such planets to stellar UV radiation critical for both the evolution of a planet's atmosphere and our potential to characterize it. Using the early M star members of nearby young moving groups, which sample critical ages in planet formation and evolution, we measure the evolution of the GALEX NUV and FUV flux as a function of age. The median UV flux remains at a 'saturated' level for a few hundred million years, analogous to that observed for X-ray emission. By the age of the Hyades Cluster (650 Myr), we measure a drop in UV flux by a factor of 2-3 followed by a steep drop from old (several Gyrs) field stars. This decline in activity beyond 300 Myr follows roughly t {sup –1}. Despite this clear evolution, there remains a wide range, of 1-2 orders of magnitude, in observed emission levels at every age. These UV data supply the much-needed constraints to M dwarf upper-atmosphere models, which will provide empirically motivated EUV predictions and more accurate age-dependent UV spectra as inputs to planetary photochemical models.

HAZMAT. II. Ultraviolet Variability of Low-mass Stars in the GALEX Archive

The ultraviolet (UV) light from a host star influences a planet’s atmospheric photochemistry and will affect interpretations of exoplanetary spectra from future missions like the James Webb Space Telescope . These effects will be particularly critical in the study of planetary atmospheres around M dwarfs, including Earth-sized planets in the habitable zone. Given the higher activity levels of M dwarfs compared to Sun-like stars, time-resolved UV data are needed for more accurate input conditions for exoplanet atmospheric modeling. The Galaxy Evolution Explorer ( GALEX ) provides multi-epoch photometric observations in two UV bands: near-ultraviolet (NUV; 1771–2831 Å) and far-ultraviolet (FUV; 1344–1786 Å). Within 30 pc of Earth, there are 357 and 303 M dwarfs in the NUV and FUV bands, respectively, with multiple GALEX observations. Simultaneous NUV and FUV detections exist for 145 stars in both GALEX bands. Our analyses of these data show that low-mass stars are typically more variable in the FUV than the NUV. Median variability increases with later spectral types in the NUV with no clear trend in the FUV. We find evidence that flares increase the FUV flux density far more than the NUV flux density, leading to variable FUV to NUV flux density ratios in the GALEX bandpasses.The ratio of FUV to NUV flux is important for interpreting the presence of atmospheric molecules in planetary atmospheres such as oxygen and methane as a high FUV to NUV ratio may cause false-positive biosignature detections. This ratio of flux density in the GALEX bands spans three orders of magnitude in our sample, from 0.008 to 4.6, and is 1 to 2 orders of magnitude higher than for G dwarfs like the Sun. These results characterize the UV behavior for the largest set of low-mass stars to date.

Hazmat Incident in New Mexico: Sulfur Dioxide Alarm

Sandia National Laboratories (SNL) is a multimission laboratory located in Albuquerque, New Mexico, and is one of three National Nuclear Security Administration research and development laboratories located in the United States. Recently, SNL’s Emergency Response Team (ERT) responded to an incident involving a sulfur dioxide (SO2)-fixed monitor, setting off the alarm inside a laboratory and in the adjacent hallway. The potential sources for the alarm were various experiments involving batteries and an uninterrupted power supply (UPS) in the immediate area.

Oxidizer Testing on Alternative Absorbents for Los Alamos National Laboratory - 18656

In the summer of 2016, during glovebox operations in TA-55, cheesecloth, a cellulosic material, was used to clean up a small spill of 9.8 molar nitric acid (oxidizer). Because cellulosic materials and oxidizers are incompatible, this prompted a chemical compatibility evaluation of the waste in TA-55 to determine if this waste was Resource Conservation and Recovery Act (RCRA) ignitable waste (D001) or RCRA reactive waste (D003). After testing and consulting with the Carlsbad Field Office in Carlsbad (CBFO), Los Alamos National Laboratory (LANL) NPI-7 decided to look for alternative absorbents to use in the gloveboxes that would not create an incompatibility issue with an oxidizer. While small spills are infrequent, they do happen and LANL wanted to be proactive and search for a material that would be compatible with an oxidizer. In December 2016, LANL NPI-7 requested LANL-Carlsbad's (LANL-CO) Difficult Waste Team to perform compatibility testing on potential alternative wipes for disposal at the Waste Isolation Pilot Plant (WIPP). The purpose for testing was to meet the Operational Experience Level 3 (OE-3) requirements that states 'any proposed use of organic absorbents or engineered absorbents in combination with potentially oxidizing TRU waste, wet or dry, should be evaluated and approved by the National TRU Program, Carlsbad Field Office' [1]. LANL NPI-7 requested LANL-CO to perform these tests because they were the group that performed all of the oxidizer testing for CBFO for the Basis of Knowledge (BoK) [2]. LANL NPI-7 chose nine fabrics and KMI Zeolite to be tested. The testing in Carlsbad took approximately 2 months to prepare the procedures, test plans and for the procurement of items. The burn rate testing was done in accordance with the requirements discussed in the BoK and approved by the LANL-CO Difficult Waste Team. Each absorbent was tested for 1) capacity limiting tests, 2) verifying the non-oxidizer threshold concentration of the oxidizer and 3) establishing the non-oxidizer concentration based on the experimental results. The effect of rinsing cheesecloth samples that have absorbed an oxidizer was also tested [3]. The burn rate testing provided three potential alternative absorbents (Spilfyter Hazmat Sorbent SM Pads Premium, Kimtech Pure W4 Wipers and Polybenzimidazole (PBI) Staple fiber) that produced a non-oxidizer result as defined by the BoK. Two wipes Spilfyter Hazmat Sorbent SM Pads Premium and Kimtech Pure W4 Wipers were able to absorb the highest concentration of potassium nitrite and still produce a non-oxidizer. TA-55 has used Spilfyter Hazmat Sorbent SM Pads Premium for a number of years in several of the processes and has ordered Kimtech Pure W4 Wipers for use in the facility. PBI fabric passed at 25 wt. % solution. (authors)

Bridging the Radiation Science Divide Between Scientists and First Responders

To be prepared for a response to a complex radiological or nuclear emergency, the first responder community must incorporate radiation protection principles, and be able to conduct tactical operational measurements, assess data, and determine associated health risks. While these actions must occur promptly in the first hours of an unfolding crisis, the on-scene responders must do so with no scientific support from radiation protection experts, such as from the central government. To further the challenges to effectively perform these actions, local hazardous material (HAZMAT) response teams, which are usually the source of technical expertise at the scene of a hazardous materials release, rarely encounter radiological materials or respond to large-scale radiological or nuclear emergencies.

Development of an Active, Man-Portable, Cooling System with Dehumidification Capabilities for Personal Protective Clothing/Equipment

Mainstream Engineering Corporation completed a highly successful SBIR program, during which we developed and commercialized products for microclimate cooling systems (MCS) and the heating, ventilation, air-conditioning, and refrigeration (HVAC/R) industry. We are marketing the MCS family of products for use with personal protective clothing/equipment (PPC/PPE) for firefighters, workers in clean rooms, HAZMAT response and other contamination/remediation teams, and military personnel that are required to wear Mission-Oriented Protective Posture (MOPP) suits and bomb disposal suits. Workers in these industries risk heat stress when confined within protective garments while in hot and humid environments. Our family of MCS and HVAC/R products that resulted from this SBIR program includes: 1. Active, Man-Portable, MCS for PPC/E—Our active system provides 350 W cooling of personal cooling for workers in thermally stressed environments. Although industrially hardened, this system is compact (0.69 ft 3 ) and lightweight (22.9 lbs). The MSC is easily decontaminated or disposed of between uses. 2. Miniature Screw Compressor for MCS—Our 350 Wcooling miniature screw compressor was originally designed for MCS and personal cooling systems. Occupying only 11 in 3 and weighing 1.4 lbs, the size and weight are less than any commercially available compressor with a similar cooling capacity. This miniature screw compressor is marketable as a low-pressure compressor or refrigerant pump. 3. Miniature Sliding Vane Compressor and Drive for MCS—Our 350 Wcooling compressor subassembly consists of a commercial miniature sliding vane compressor packaged with our motor controller. At 29.4 in3 and 1.5 lbs, this compressor is larger and heavier than the miniature screw but is lower cost and capable of producing higher head pressure. 4. Small Screw Compressor for HVAC/R—Our 50 kW cooling small screw compressor is for commercial HVAC/R applications. This compressor is extremely power dense at 0.34 ft 3 and 43 lbs and has a specific cooling capacity (kW/lb) five times greater than existing commercial compressors. We demonstrated high reliability (>5,100 hrs of operation and >3,400 on/off cycles), and we are currently discussing commercialization opportunities with laser manufacturers for cooling of their high-power devices. This final report summarizes the design, fabrication, testing, features, and benefits of each product. The commercialization potential and recommendations for the future are included.

Rapid Radiological/Nuclear Consequence Assessment Tools

The goal of this work is to design a tool for rapid assessment of the areas impacted by airborne plumes and fallout from a radiological/nuclear incident, such as an Improvised Nuclear Device (IND) detonation or Radiological Dispersal Device (RDD) release, for use by state and local technical specialists and emergency responders. The tool would produce information on the distances and areas near an incident location in which hazards may exist. This would inform consequence management decisions by state and local responders in the critical minutes following an event, as well as assist in emergency planning before an incident. The products would be intended for use before more detailed products are available from non-local assets, such as the federal Interagency Modeling and Atmospheric Assessment Center (IMAAC) and the Federal Radiological Monitoring and Assessment Center (FRMAC). The tool’s products could provide, for example, predictions of damage zones and dangerous fallout areas to help guide the emergency response, including protection of emergency responders and the public. The initial focus of this effort is on the more difficult IND decision support tools. Existing HAZMAT tools and RDD guidance, described in this report, can also be integrated into the decision support tool.

Utilization of Local Law Enforcement Aerial Resources in Consequence Management (CM) Response

During the past decade the U.S. Department of Homeland Security (DHS) was instrumental in enhancing the nation’s ability to detect and prevent a radiological or nuclear attack in the highest risk cities. Under the DHS Securing the Cities initiative, nearly 13,000 personnel in the New York City region have been trained in preventive radiological and nuclear detection operations, and nearly 8,500 pieces of radiological detection equipment have been funded. As part of the preventive radiological/nuclear detection (PRND) mission, several cities have received funding to purchase commercial aerial radiation detection systems. In 2008, the U.S. Department of Energy, National Nuclear Security Administration Aerial Measuring System (AMS) program started providing Mobile Aerial Radiological Surveillance (MARS) training to such assets, resulting in over 150 HAZMAT teams’ officers and pilots from 10 law enforcement organizations and fire departments being trained in the aerial radiation detection. From the beginning, the MARS training course covered both the PRND and consequence management (CM) missions. Even if the law enforcement main focus is PRND, their aerial assets can be utilized in the collection of initial radiation data for post-event radiological CM response. Based on over 50 years of AMS operational experience and information collected during MARS training, this presentation will focus on the concepts of CM response using aerial assets as well as utilizing law enforcement/fire department aerial assets in CM. Also discussed will be the need for establishing closer relationships between local jurisdictions’ aerial radiation detection capabilities and state and local radiation control program directors, radiological health department managers, etc. During radiological events these individuals may become primary experts/advisers to Incident Commanders for radiological emergency response, especially in the early stages of a response. The knowledge of the existence, specific capabilities, and use of local aerial radiation detection systems would be critical in planning the response, even before federal assets arrive on the scene. The relationship between local and federal aerial assets and the potential role for the further use of the MARS training and expanded AMS Reachback capabilities in facilitating such interactions will be discussed.

The Heroes' Problems: Exploring the Potentials of Google Glass for Biohazard Handling Professionals

In “white powder incidents” or other suspicious and risky situations relating to deadly diseases or chemicals (e.g., Ebola investigation), those who handle the potentially hazardous materials are the heroes who spearhead the first responder’s operations. Although well trained, these heroes need to manage complex problems and make life-or-death decisions while handling the unknown and dangerous. We are motivated to explore how Google Glass can facilitate those heroes’ missions. To this end, we conducted contextual inquiry on six biohazard-handling, Personal Protective Equipment (PPE)-wearing professionals. With an inductive thematic analysis, we summarized the heroes’ workflow and four groups of “Heroes’ Problems”. A unique “A3 Model” (Awareness, Analysis, Action) was generated to encapsulate our qualitative findings and proposed Glass features. The findings serve as the groundwork for our future development.

Examining Rail Transportation Route of Crude Oil in the United States Using Crowdsourced Social Media Data

Safety issues associated with transporting crude oil by rail have been a concern since the boom of the U.S. domestic shale oil production in 2012. During the last decade, over 300 crude-oil-by-rail incidents have occurred in the United States. Some of them have caused adverse consequences including fire and hazardous materials leakage. However, only limited information on crude-on-rail routes and their associated risks is available to the public. To this end, this study proposed an unconventional way to reconstruct crude-on-rail routes using geotagged photos harvested from the Flickr website. The proposed method linked the geotagged photos of crude oil trains posted online with national railway networks to identify potential railway segments that those crude oil trains were traveling on. Here, a shortest path-based method was applied to infer the complete crude-on-rail routes, by utilizing the confirmed railway segments as well as their directional information. Validation of the inferred routes was performed using a public map and official crude oil incident data. The results suggested that the inferred routes based on geotagged photos had high coverage, with approximately 96% of the documented crude oil incidents aligned with the reconstructed crude-on-rail network. The inferred crude oil train routes were found to pass through several metropolitan areas of high population density, who were exposed to potential risk. These findings could improve situational awareness for policy makers and transportation planners. In addition, with the inferred routes, this study has established a good foundation for future crude oil train risk-analyses along the rail route.
