is '. In medieval times, anyone who worked with lead was referred to as a plumber; this can be seen from an extract about workmen fixing a roof in Westminster Palace; they were referred to as plumbers: "To Gilbert de Westminster, plumber, working about the roof of the pantry of the little hall, covering it with lead, and about various defects in the roof of the little hall".
Thus a person with expertise in working with lead was first known as a ''Plumbarius'' which was later shortened to ''plumber''.

United States
Each state and locality may have its own licensing and taxing schemes for plumbers. Some states license journeymen and master plumbers separately, while others license only master plumbers. To become licensed, plumbers must meet standards for training and experience, and in most cases, pass a certification exam. There is no federal law establishing licenses for plumbers.
Canada
In Canada, licensing requirements differ by province; however, the provinces have pooled resources to develop an Interprovincial Program Guide that developed and now maintains apprenticeship training standards across all provinces. The
Red Seal Program, formally known as the Interprovincial Standards Red Seal Program, is a program that sets common standards to assess the skills of tradespeople across Canada. The Red Seal, when affixed to a provincial or territorial trade certificate, indicates that a tradesperson has demonstrated the knowledge required for the national standard in that trade.

Australia
Plumbing work is defined in the Australian Standards (AS3500) Regulations 2013 and refers to any operation, work or process in connection with installation, removal, demolition, replacement, alteration, maintenance or repair to the system of pipes and fixtures that conveys clean water into and liquid waste out of a building.
To become a licensed plumber a four year apprenticeship and a Certificate III in Plumbing is required.
As part of this course, instruction in the basics of gas fitting will be undertaken. Upon completion, these basics in gas fitting will allow the plumber to not only apply for his plumbing license but also an interim gas license and carry out gas work under the supervision of a fully qualified gas fitter.
To obtain a full gas license from the Department of Mines and Energy, the plumber will need to have worked on an interim gas license for a minimum period of twelve months and successfully completed a Certificate IV in Plumbing.
Dangers
There are many types of dangers to a plumber. These include electric shock, strains and sprains, cuts and lacerations, bruises and contusions, fractures, burns and scalds, foreign bodies in the eye, and hernias. Working at height or in confined spaces, or working with lead and asbestos are all on-site dangers that plumbers can face.
