Fire Safety in Healthcare Facilities: An Indian Perspective
Abstract: Fire protection and safety measures in hospitals are of utmost importance to ensure the safety of patients, staff, and visitors. Due to the patients' limited mobility, hospitals are more susceptible to fire disasters. Short-circuits, basements being used as storehouse, inappropriate storage of flammable liquids, improper power supply load, false ceiling panel lined with thermocol, faulty electric wirings, and overheating leading to burning of wires are some of the common causes …

Sustainable Manufacturing: The Role of Additive Technologies in Waste Reduction
Abstract: Additive manufacturing (AM) is transforming modern manufacturing by significantly reducing material waste while enabling highly efficient production processes. Unlike conventional subtractive manufacturing methods—such as cutting, drilling, and milling—which remove excess material and generate large volumes of scrap, AM constructs objects layer by layer, depositing material only where required. This precise material placement minimizes waste generation and supports resource-efficient production, making AM a critical technology for sustainable industrial development. Beyond waste …

Assessment of Acoustic Noise Generated from Machines in a Mechanical Workshop Using 1-Octave Band Frequency Analysis
Abstract: Acoustic noise is one of the prominent occupational health hazards, particularly in manufacturing and process industries. Prolonged exposure to loud noise can cause noise induced hearing loss of the exposed personnel. Limiting the exposure to noise intensity within its permissible exposure limit is adopted as one of the administrative control measures to reduce the risk of hearing loss. However, frequency specific assessment of occupational noise exposure is limited. Here, we …
