Designing Safety Vests to Fit Women
Get PDFThis paper focuses on the design and construction of safety vests for women, particularly in XS and XXL sizes. Safety vests are an essential piece of protective equipment worn by individuals working in environments requiring high visibility for safety reasons. The American National Standards Institute (ANSI) and the International Safety Equipment Association (ISEA) develop safety vest standards to ensure 360-degree visibility of workers, but these standards create limitations in manufacturer’s abilities to create a well-fitted vest for women of smaller stature, particularly in the sizes between XXS and S, as the required square inches of material result in a baggy fit. This project aims to improve the design of safety vests to provide a better fit for women by using a woman-specific bodice block pattern, which addresses the areas of discomfort women have identified with their vests in previous studies. The paper discusses the process of designing and creating a high-visibility safety vest, including the creation of a bodice block, pattern, and vest construction. Both of the resulting vests were measured and compared to ANSI/ISEA standards to determine whether they met the minimum square inch requirements. With more women entering the field of construction, the design of safety vests should be updated to fit their bodies from both a safety and comfort standpoint

Building San Francisco, CA
Get PDFThe objective of this report is to conduct a thorough analysis and evaluation of the existing fire life safety and fire protection systems in place at the Building located in San Francisco, California. The building is classified as a Type II-A building and serves predominantly as office space. The building is six stories tall with a total gross area of approximately 97,170 SF.
The initial portion of this report concentrates on a thorough prescriptive-based analysis, which provides an evaluation of the egress design, fire alarm system, communication systems, fire suppression system, structural and construction design, smoke control, and flammability requirements. The results of this comprehensive analysis demonstrate that the building complies with the requirements of the applicable building and fire codes.
The subsequent portion of this report provides a performance-based analysis, which evaluates two distinct fire and life safety assessments. The first assessment involved the evaluation of the I.T. room located in the basement, with a focus on identifying potential flashover occurrences, the activation times of smoke and sprinkler detection, and the possibility of secondary ignition. The outcomes of this analysis revealed that flashover is unlikely to occur, with smoke detection activation taking approximately 674 seconds, and sprinkler activation occurring approximately 744 seconds after the onset of the fire. Note that the activation times appear relatively long for a room of this size, which is understood to be primarily due to the inclusion of the fire\u27s incipient slow growth phase. The results also indicated that secondary ignition does occur. These results suggest that the room is vulnerable to a fire scenario that could significantly impact the operations of the business and safety of occupants. To mitigate this risk, it is recommended that a fire protection system, such as a clean agent halon system or CO2 system, be installed to suppress fires and minimize equipment damage. Additionally, regular equipment maintenance performed by qualified professionals should be conducted to minimize the risk of ignition. The room should also be regularly inspected to ensure that the space does not contain large amounts of combustible materials to reduce potential fuel sources.
The second fire scenario involves the atrium, which connects the basement level to the second floor. The design fire occurs at the base of the atrium in the basement. The scenario was assessed using Fire Dynamic Simulator (FDS) and Pathfinder to determine the Available Safe Egress Time (ASET) and Required Safe Egress Time (RSET). The primary objective was to determine whether the ASET exceeds the RSET, thus ensuring that the building and its associated life safety systems can maintain a safe and tenable environment for all occupants to evacuate safely. The ASET analysis will specifically focus on the deployment of the fire-rated shutters to assess whether the conditions on the levels above the fire, as well as the areas remote from the fire, will remain safe and suitable for the evacuation of building occupants. Pathfinder was utilized to determine the RSET, and the results indicated a time of 1034 seconds (~18 minutes) which takes into account a 1.5x safety factor.
ASET was calculated by FDS, which simulated and assessed various tenability criteria, including smoke layer descent, heat exposure, visibility, and carbon monoxide dosing. The results indicated that the ASET could be maintained for 18 minutes for floors and areas remote from the fire. This is primarily due to the activation of fire-rated shutters, which compartmentalized the basement from the floors above. It should be noted that the atrium complies with all applicable prescriptive code requirements. The analysis emphasizes the crucial role of fire safety equipment functioning properly to ensure the safety of occupants within the building. The primary recommendation is to minimize potential ignition sources and fuel sources near the atrium. Additionally, regular equipment inspection and maintenance from qualified professionals should be conducted to ensure that the fire alarm system, automatic sprinkler system, and fire-rated shutters operate properly
“Civil Dialogue” as Feminist Pedagogy: Engendering Material and Symbolic Movement
Get PDFIn the United States, we are socialized to think in Western dualisms, and these patterns of communication characterize discussion of social issues. Consequently, discussion becomes debate and dominant approaches to inquiry are privileged over experience with persuasion being the end goal. Fostering agency, cultivating empathetic understanding, and facilitating critical thought are made more difficult—outcomes that are neither productive nor edifying in the college classroom. This original teaching activity resists hierarchical forms of debate in favor of visibility and solidarity in discussions of gendered violence. Grounded in principles of invitational rhetoric and provocation, the activity uses a “Civil Dialogue” format to prompt engaged discussion of consent relative to university life. Students assess the effectiveness of sexual assault prevention campaign slogans (e.g., “Consent Is Sexy”) by situating themselves along a spectrum of opinion by degrees of agreement, neutrality, and disagreement, where the goal is an understanding of positions rather than motives. By situating a precarious topic in a communal space where narrative is privileged and movement is validated, the activity is a powerful exercise in identification and sensemaking. Outcomes include development of civil speech and listening skills and the co-creation of knowledge by diverse voices. The activity is adaptable to other curricula, including critical methods and health campaigns
Inguinal Wound Vacuum Dressing
No full textNegative pressure wound therapy (NPWT) is a prevalent medical procedure that accelerates the healing process for open wounds post-operation. Currently, a disease called necrotizing fasciitis is becoming more frequent in the inguinal area of women. NPWT has demonstrated great outcomes for the post-operational treatment of necrotizing fasciitis, however, two problems arise: the inguinal geometry is complicated, making it difficult to apply NPWT materials and NPWT materials will occasionally cover the urethra and anus, preventing patients to urinate and defecate. This document describes the conceptualization, testing process, and final design of a modification to current, medical-grade NPWT that solves the problems stated for NPWT application on the female inguinal region. Highlights of this modification are specialized NPWT material geometry and flexible ports that accommodate for an inserted rectal tube and/or foley catheter
Drop Test Release Mechanism
Get PDFMany boxes for shipping undergo drop tests by the manufacturer to ensure their durability. Certain constraints are necessary to successfully carry out these tests such as not damaging the box prior to the drop and maintaining consistency throughout every drop.
Our team has designed a Drop Test Release Mechanism that addresses these constraints. It provides repetitive drops for different objects that vary in shape and size such as small electronics or parts. This device utilizes a soft-clamping mechanism that can release an object with minimal force applied onto it prior to drop. A frame made of 80/20 was designed to provide rigidity to the soft-clamping mechanism. The soft clamping mechanism supports the object between it by utilizing foam and a friction pad to induce a high friction force. The clamp can be adjusted for multiple sized objects by use of sliding rails that allow it to widen or tighten. Our design focuses on just the release of the test object. A test stand to introduce varying heights must be designed for a fully functional drop test measurement process.
The final prototype was tested to analyze the effectiveness of our design. The tests involved verifying the repeatability of the drop mechanism by testing the object to see if it fell in the same orientation and with the same impact each time. The drop mechanism passed these tests but failed at a usability test and an electronic test. The report goes into detail about the design and testing of the prototype

SLO City Riparian Grazing Project Handbook
No full textA handbook for future leads on this project. This project is about the vegetation surveying of several segments of Prefumo and San Luis creeks that flow through the city of San Luis Obispo. The city needs to open up the undergrowth in the creeks to allow crews to find and clear out debris for flood and fire prevention. We are mapping the vegetation to help Beth Reynolds plan where to set up temporary grazing units for her goats, and we will be photographing the condition of the creek (riparian) channels before the grazing begins and after in order to document the effectiveness of the grazing treatment
