Window cleaner

Window cleaning, or window washing, is the exterior cleaning of architectural glass used for structural, lighting, or decorative purposes. It can be done manually, using a variety of tools for cleaning and access. Technology is also employed and increasingly, automation.
Commercial work is contracted variously from in-person transactions for cash or barter, to formal tender processes. Regulations, licensing, technique, equipment and compensation vary nationally and regionally.
Methods of access and equipment related to both access and cleaning vary nationally and regionally. If a window is not easily accessible using one type of equipment then it is advisable to combine different tools to be able to clean it properly.
Direct access to a window obtained by egress from that window. This method is still used at the Empire State Building in New York City.
Windows that needed cleaning became higher as buildings became higher. A trade in window cleaning developed, for instance, in New York City in the late 19th century when early skyscrapers were being built. The height increased the risk to the washers. At first, washers cleaned skyscraper windows by standing on the window ledge and holding onto the frame. Later, leather safety belts attached to anchor bolts were introduced and then scaffolds. For example, the Otis Elevator Company built an electrically operated scaffold for use at Lever House.
Three window cleaners were working at the World Trade Center at the time of the September 11 attacks. Jan Demczur, Polish employee working in the North Tower, survived and helped save five other people who had been trapped in an elevator with him. Roko Camaj and Fabian Soto, working in the South Tower, were killed.
Risks include slipping on water or soap, and falling from heights. In 1932 in New York, an average of one out of every two hundred window cleaners were killed per year. On May 29, 1962, four window cleaners were killed when a scaffold fell at the Equitable Life Building. In 1993 Local 32BJ, the New York window cleaners' union, launched an apprentice training program, increasing job safety among its members, although increasing numbers of New York window cleaners are non-unionized.
Unlike in Scotland, there is no government licensing in the United States, England or Wales - this means anyone can claim to be a window cleaner. Window cleaning is considered the most dangerous job in the UK. Several window cleaners die each year, and many are injured.
Many window cleaning businesses are claiming that laws are about to come into force due to European Directive 2001/45/EC that will make ladders illegal for window cleaners. However, the government denies this stipulation, as ladder use for window cleaning is "low risk and short duration":
The Working at Height Regulations came into force in 2005 and does not ban ladders but merely restricts their use to safe methods, i.e. foot it by person or with a ladder stopper:
The HSE favours the use of scaffold towers, i.e. temporary workstations, for window cleaning but says this is rather awkward:
Although Water Fed Pole (WFP) systems are meant to be safer than ladders, the Health and Safety Executive has said that they spill large amounts of water which either the window cleaner or their client could slip on.
Another issue is how "green" window cleaning companies are seen to be. During the spring of 2006 Defra considered banning the non-essential use of water and extending their already tight restrictions to prevent the use of water-fed safer which reach up to 60 ft. Window cleaners could return to the bucket-and-mop method, because Health and Safety Working at Heights allows such for temporary access. Many window cleaners and window cleaning companies argue that their usage of water is minimal in comparison with water usages of large industry and energy companies, and that their water usage accounts for a small percentage of overall water consumption in developed countries.
Much progress has been made in the area of minimizing the need for labor in this industry by use of technology. The availability of technology such as the pressure washer has made it more efficient.
More recently, in high tech societies the use of fully automated robotic window cleaners, also for houses, is starting to become common.
Window cleaning and window cleaners are the subject of songs, films and comment, often with comic intent. Examples include George Formby's comic song "The Window Cleaner", also known as "When I'm Cleaning Windows" is one of the best known. Films about window cleaners include The Window Cleaner (1968) and Confessions of a Window Cleaner (1978). Journalists sometimes comment on the peculiarities of the trade.
