Rope access is used for various purposes, some of which are:
The workplace is difficult to reach.
A riser is not enough.
A tap is too expensive.By means of so-called rope access, employees can reach the workplace quickly, safely and economically.
Using rope techniques, people with access experts can reach places that are difficult or impossible to reach with scaffolding, cranes or other means.
The use of rope access is also usually a more economical solution for carrying out work in hard-to-reach places.
Example: Building scaffolding that often costs a lot of equipment and man hours. Can reach the workplace in a very short time with rope access and start with the assignment.
Now, rope access is often seen as dangerous. Worldwide, however, relatively fewer accidents with rope access have been registered than with scaffolding, ladders, or cranes.
This is partly due to all safety regulations and a great sense of responsibility and the strict safety requirements that the contractors must meet and the modern climbing materials with which they work.
three main methods of cleaning facades are water, chemical, and abrasive treatments. Abrasive treatments, such as grinding, sanding, and blasting, are not recommended as they remove surface material along with dirt and paint. That leaves behind water and chemical treatments, both of which are effective and safe when used correctly.
Water
There are three types of water-based facade cleaning methods:
• washing under pressure
• soak
• wash with steam / under high pressure
water pressure cleaning
The most common method is pressure cleaning, where you apply a low to medium pressure sprayer (100 to 400 pounds per square inch) to the surface of the building. (As a reference point, the spray from a garden hose is about 60 psi.) Water pressure usually starts low and is increased as needed, followed by scrubbing with a natural or synthetic (but not metal) brush for stubborn areas and detailed features.
Soaking involves spraying or misting the masonry surface for extended periods, usually up to a few days at a time, to loosen heavy build-ups of soot and crusts, especially in areas of the building not exposed to rain. Soaking, used in conjunction with pressure and followed by a final rinse with water, requires repeated applications that can last several weeks. But because it is mild, it is ideal for historic masonry.
The third method, steam or high-pressure cleaning, is not commonly used but can effectively remove built-up dirt deposits and plants, such as ivy. It is also an option for cleaning stones sensitive to the acids used in some chemical cleaners.
Chemicals
Chemical cleaners are effective for removing dirt and unlike water-based treatments, they can also be used to remove paint, coatings, metal stains and graffiti. Acid-based cleaners are effective on unglazed brick and terracotta, cast stone, concrete, granite and most sandstones. Alkaline cleaners are best used on acid-sensitive masonry, such as limestone, marble, polished granite, and calcareous (chalky) sandstone.
Abrasive treatments
Abrasive treatments
Some stones may contain impurities, such as iron particles that can react with certain cleaning agents, causing stains. Choosing the wrong type of cleaning method can cause irreversible damage to the building materials, so when in doubt, it is best to consult a historic preservationist about the masonry composition.
Also, keep in mind that some chemicals (and even water) that are safe for masonry can corrode or damage other building elements, such as decorative metal elements, glass, wooden window frames, iron window bars, and window air conditioner sleeves. All parts of the building that cannot be cleaned but are prone to damage must be covered or otherwise protected.
Safety tips for cleaning outside windows
Your dirty, dusty windows could be the reason why 5 pm. Sunsets will make you want to retire under a Snuggie.
Dirty windows significantly limit the amount of sunlight that fills a room during short winter days. The lack of natural light can put even the sunniest people into hibernation.
Whether you live in a walk-up or detached house on the fifth floor, you won’t have to spend a minute more looking out of dirty glass. Here are five ways to get your windows sparkling clean inside and out for the winter.
Magnetic window cleaner
Cleaning the outside of windows that won’t unlock and sink into a room is no easy task, especially for apartment dwellers, unless you want to stagger precariously on a window frame. Or you can pick up a magnetic window cleaner that doesn’t risk life or limb.
Such tools wash both sides of a window at once with microfiber cloths to wipe off whatever liquid cleaning product you decide to use.
People who own these gadgets say it takes some practice to get the tool to slide smoothly. For example, if you spin it too fast while cleaning, the magnets may loosen.
