The word plumber comes from the Dutch word ploog, which means “to dig”.
The term was first used in the 19th century to refer to plumbers who worked on railways and in mines.
In South Korea, the term is often used to refer specifically to the profession of plumber.
South Korea’s Ministry of Labor, Industry and Trade recently reported a sharp rise in complaints of workplace safety and illegal workplace practices during the construction of the Yalu Dam, a massive hydroelectric project.
In June, the Korea Times reported that at least 17 workers were injured in a dispute at a construction site on the site of the dam, and four were killed.
Workers and local authorities said the incident occurred in September when the construction workers and contractors used heavy equipment to remove a bridge over a nearby river, causing a sinkhole.
A spokesperson for the Korean Workers’ Union (KWU) said it would investigate the case.
“Our union is concerned about the construction safety of the work site and the safety of our workers, but also about the use of heavy machinery and the illegal workplace conditions that were experienced,” said Gwang Il Sung, a spokesperson for KWU.
According to the Seoul Metropolitan Government, the construction work at the dam was suspended last October after a series of deadly accidents.
Seoul’s government said that construction on the dam is being conducted under safe working conditions.
The Ministry of Health, Labor and Welfare (MOHLL) reported that the number of injuries among construction workers had declined by 17 percent over the past six months compared to the same period last year.
On Friday, an accident at a quarry in the western province of Gyeonggi-do caused the deaths of at least 14 workers, the Ministry of Land, Infrastructure and Transport said.
There were also four deaths and nine injuries in other parts of the country.
