To define and secure boilers safely, some professional specialized organizations such as the American Society of Mechanical Engineers (ASME) develop standards and regulation codes.
For instance, the ASME Boiler and Pressure Vessel Code is a standard providing a wide range of rules and directives to ensure compliance of the boilers and other pressure vessels with safety, security and design standards.5 Historically, boilers were a source of many serious injuries and property destruction due to poorly understood engineering principles.Thin and brittle metal shells can rupture, while poorly welded or riveted seams could open up, leading to a violent eruption of the pressurized steam.
Because of this, steam is a great way of moving energy and heat around a site from a central boiler house to where it is needed, but without the right boiler feed water treatment, a steam-raising plant will suffer from scale formation and corrosion.
At best, this increases energy costs and can lead to poor quality steam, reduced efficiency, shorter plant life and unreliable operation.At worst, it can lead to catastrophic failure and loss of life.
Collapsed or dislodged boiler tubes can also spray scalding-hot steam and smoke out of the air intake and firing chute, injuring the firemen who load the coal into the fire chamber.
Extremely large boilers providing hundreds of horsepower to operate factories can potentially demolish entire buildings.Źródło: https://en.wikipedia.org/wiki/Boiler#Safety
Similar repairs are done at home.
But in such buildings often you have to also carry out work related to repair leaks resulting in the installation of plumbing.
This is because the state of the responsibility of owners of housing blocks and homes can have installations mounted a dozen years earlier.Similar situation may occur also in the case of hospitals..
