Petroleum facilities containing welded steel bulk flammable liquid product storage tanks possess sundry fire hazards inherent to the facility. These installations urgently require indigenous efficient firefighting systems. So, the efficient design of firewater and firefighting foam system is dynamic in controlling fire-related emergencies. The paper deals with the in-depth conceptualization of the design and analysis of firefighting systems for a typical petroleum handling, processing and storage facility in compliance with international standards. The study is aimed to formulate the elementary technique for designing an optimized firefighting system. The proposed objective was achieved by considering an ideal tank farm site that is most commonly located in a range of terminal stations, pumping stations, petroleum refineries, well sites, etc. Sufficient illumination was enumerated on the standardized classification of the liquid fuel product with respect their flammability range. Special guidelines regarding firefighting system design basis were defined and an optimized firefighting and foam system design was developed. Moreover, sufficient limitations that must be considered during the firefighting of huge tank fires are discussed. This comprehensive numerical design philosophy offers a simple and wide-ranging guide to industrial practitioners by formulating the principles for industrial firefighting system design.

To enhance the performance of fluorine-free firefighting foam, a mixed dispersion system comprising silica nanoparticles (SiO NPs), guar gum (GG), and surfactants was developed and systematically evaluated. Compared with systems containing only NPs or GG, the combined formulation significantly improved foam stability and rheological properties. The optimized GG-NPs formulation exhibited the lowest drainage volume and the highest storage modulus, indicating enhanced structural integrity.

Background: Rescue services work is in constant change, yet operational responsibilities in high-stakes, unpredictable environments remain. In this study, we are interested in individual psychological performance, conceptualized as a balance between the challenges or threats perceived in a situation and one’s sense of capability and resources, with the goal of successfully completing tasks. We explored the effects of working amidst continuous change on individual psychological performance and its maintenance among rescue service personnel with three research questions: (1) What kinds of changes have occurred in the work of rescue services? (2) What effects does work amidst changes have on individual psychological performance from the perspective of rescue service personnel? and (3) How can individual psychological performance be supported amidst changes from the perspective of rescue service personnel?
Methods: This was a qualitative interview study with fire officers and fire sub-officers ( = 18) from five rescue departments across Finland.

Polycyclic aromatic hydrocarbons (PAHs) are increasingly recognized as a major contributor to the occupational cancer risk among firefighters. In response, the National Fire Protection Association (NFPA) and other regulatory bodies have recommended rigorous decontamination protocols to minimize PAH exposure. Despite these efforts, a critical gap persists: the absence of real-time, field-deployable devices capable of detecting these invisible and toxic compounds during firefighting operations or within fire stations.

Out-of-hospital cardiac arrest (OHCA) is a leading cause of mortality. Despite public awareness campaigns, widespread cardiopulmonary resuscitation (CPR) training initiatives, and deployment of public access defibrillators, potentially life-saving bystander intervention occurs inconsistently. Mobile technologies that alert nearby lay responders or off-duty professionals to OHCA events have emerged as a strategy to increase bystander CPR and AED use.

Objective: Public safety personnel (PSP) frequently screen positive for posttraumatic stress disorder (PTSD) based on the PTSD Checklist for (PCL-5). Approximately 30% of Canadian paramedics who might otherwise screen positively for PTSD using the PCL-5 may not because avoidance items are not endorsed, arguably as a function of their service requirements (e.g.
