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 …

Application of flux cored arc welding (fcaw) without pre-heating for heavy structures in ship building fabrication & construction of heavy offshore structural steels
Abstract: In fusion welding processes, the reason often given to explain the need for preheating, controlling the inter pass temperature (in multi-pass welds), and post-weld heat treatment (PWHT) is to reduce the risk of residual stresses and it can be removed by heating weldment in the heat affected zone (HAZ). Cold cracking is a hydrogen embrittlement phenomenon, often referred to as hydrogen induced cracking or HAZ cracking. During the construction and …
