Phase change material (PCM) has been widely studied for efficient thermal management. This work is the first holistic experimental research on temperature control performance of PCM-integrated firefighters' gloves. The results showed that protection time could be extended by 2-5 times in direct contact to hot object tests and around 1.5 under radiant/convective heat source when embedding a 1-mm-thick PCM layer melting point 68°C best all test conditions since it had most phase function...
Abstract In surgical settings, infectious particulate wound contamination is a recognized cause of post-operative infections. Powered air-purifying respirators (PAPRs) are widely used by healthcare workers personal protection against aerosols. Healthcare infection preventionists have expressed concern about the possibility that particles expelled from PAPR exhalation channels could lead to associated infections, especially in operative settings where sterile procedural technique emphasized....

Firefighters face a multitude of hazards in their line duty, with overexertion being one the foremost causes injuries or fatalities. This high risk is often exacerbated by burden carrying heavy self-contained breathing apparatus (SCBA). study aims to explore impact SCBA weight on firefighters' musculoskeletal joint movements. Six firefighters participated this study, performing four simulated firefighting tasks under three different conditions. A hybrid inverse kinematics approach was...
Firefighters wear personal protective equipment to protect them from the thermal and chemical environment in which they operate. The self-contained breathing apparatus (SCBA) provides isolation of airway hazardous fireground. National standards limit SCBA weight, however, integration additional features could result an exceeding current limit. purpose this study was examine effects increased weight on firefighters' physiological responses, work output, dynamic stability, comfort. Completion...
In 2022, approximately 65,650 firefighter injuries were recorded on duty, marking an 8% rise from the 2021 tally of 60,750 [1]. The majority these took place during fireground operations, with burns and thermal stress accounting for about 15% such incidents Given this problem,a pressing need exists to advance turnout gear technology better protection firefighters. Our proposal involves integrating phase change material (PCM) into firefighters' enhance its protective capabilities through...
Transient three-dimensional (3D) heat and moisture transfer simulations were conducted to analyze the thermal performances of entire phase change material (PCM) integrated into firefighters' gloves. PCM was broken down several segments cover back palm hand but avoid finger joints keep functions. Parametric studies performed explore effects melting temperatures, locations in glove layer thicknesses on overall performance improvement The study found that could extend time for skin surfaces...
During infectious disease outbreaks or pandemics, an increased demand for surgical N95s that create shortages and necessitate the use of alternative National Institute Occupational Safety Health (NIOSH)-approved respirators do not meet Food Drug Administration (FDA) additional requirements. The objective this research was to quantify level bacterial contamination resulting from wearing NIOSH-approved lacking protections afforded by N95s.Participants performed simulated healthcare tasks while...
Powered air-purifying respirators (PAPRs) are worn to protect workers from hazardous respiratory exposures in a wide range of workplaces, including healthcare. However, PAPRs may diminish the ability wearers correctly hear words spoken by others, potentially interfering with safe performance healthcare duties. Accordingly, impact during use on speech intelligibility (SI) and consequently user safety, usability, patient care is not well studied. The objectives this study were (1) determine...
Loose-fitting powered air-purifying respirators (PAPRs) are used in healthcare settings, although barriers to routine, everyday usage remain, including usability concerns and potential interference with work activities. PAPRs approved by the National Institute for Occupational Safety Health (NIOSH) must meet minimum performance requirements, a airflow requirement of 170 L/min. One course action address is allow use designed reduced rates. The primary objective this study was assess effect...
The widespread emergence of the COVID-19 pandemic has transformed our lifestyle, and facial respirators have become an essential part daily life. Nevertheless, current possess several limitations such as poor respirator fit because they are incapable covering diverse human sizes shapes, potentially diminishing effect wearing respirators. In addition, do not inform user air quality within smart facepiece in case continuous long-term use. Here, we demonstrate novel N-95 filtering that...
The National Institute for Occupational Safety and Health's methods requirements air-purifying respirator breathing resistance in 42 CFR Part 84 do not include work of breathing. International Organization Standardization Technical Committee 94, Subcommittee 15 utilized to evaluate airflow all classes respiratory protective devices as part their development performance standards regarding devices. objectives this study were: (1) the relationship between Standardization's measurements test...
