Let’s say you’re a professional window cleaner, and you’ve been doing storefronts, small businesses, and residential jobs. You want to get into highrise cleaning, but where do you start? What sort of gear do you need?
Personal GearThere are five pieces of personal gear you’ll need to find: a harness, a bosun’s chair, a descender, a back up device, and carabiners.
The very first thing you need to invest in is a good harness. It should be comfortable for you. Since everyone has a different body, take some time to search for the right one for you. Regardless of which harness you choose, it needs a minimum of a front or back D Ring for your back-up device (but preferably will have front, back, and waist D rings). When you’re shopping, make sure that it meets ANSI standards. Your harness may also meet NFPA standards, but this isn’t crucial.Next, you’ll need a bosun’s chair, which is at its simplest just a plank suspended by rope for you to sit on as you work. You get your choice between 2-point and 4-point suspension, which means that the strap is either going to attach to two points on the plank or four. Is 4-point safer? No, not really; you’re tied off either way. It’s more a question of preference. Optionally, you can also pick a bosun’s chair that has a cushion for added comfort. Regardless of which chair you choose, make sure you pick one that has connection points for your buckets and tools!
The fourth thing you need is a back up device (also known as a rope grab). This attaches to your safety line, and catches you in case your main line fails. We recommend purchasing a self-trailing back up device that will automatically follow you down the rope without manual adjustment. Some back up rope grabs come with lanyards, but others simply specify maximum lanyard length. If that’s the kind you get, make sure to select a lanyard that is compatible with your rope grab. Also note that handle ascenders are not acceptable back up devices.
The final item on your list is a set of good carabiners. You probably already know what a carabiner is, but it’s the clip that connects all of your components together. Window cleaners will want to only use ANSI rated carabiners. Though you can use non-ANSI rated biners (and there are lots of great ones), you’ll have to be prepared to explain to an OSHA inspector why! At any rate, it’s always a good idea to have a few extra carabiners around. It can’t hurt. If you want to learn more about the jargon associated with carabiners, check out this handy info page we put together awhile back.
All of the above items are carried on your person when you descend the building, but you’ll also need ropes to descend on. Specifically, you’ll need two: your main line and a safety line. Ropes come in different sizes—7/16″, 1/2″, or 5/8″—and you’ll need to pick the right size for your equipment. In terms of length, you’ll need to pick a rope that is as long as your tallest job.
You’ll also need some way to anchor your rope. This will vary from job to job based on available anchors on the roof. We recommend having some anchor straps on hand. They can wrap around almost anything to give you your anchor point. Note that whatever you attach to has to be able to support at least 5,000 lbs.
Depending on your setting, there are other things you can get yourself such as gloves, suction cup grabbers, and more. That being said, if you have a harness, a bosun’s chair, a backup device, some carabiners, two ropes, a helmet, and a rope protector you should be good to go.
Of course, in addition to having all the right gear, you need to get proper training. High rise window cleaning is an inherently dangerous job. It is essential that you get all of the training you need before attempting any work at height.
