How to Cut Control Joints in Concrete with a Cut-off Saw, by ConcreteNetwork.com

How to Cut Safely with a Diamond Blade and Handheld Saw

We’ve shown you how control joints in concrete work. Now we’re going to show you how to make them with cut-off saws.

You can make these cuts with walk-behind or early entry saws, of course. However, some surfaces like stamped and other decorative concretes demand smaller cut-off saws, according to Bob Harris of the Decorative Concrete Institute. This video from ConcreteNetwork.com shows you how to do cut control joints in these surfaces with these saws. Watch it now, and let us know what you think in the comments section.

How to Use Fire Escapes to Access Roofs Safely, by Firefighter Toolbox

Lt. John Hayowyk, Jr. of the Passaic, NJ Fire Department has been running a three-part series on accessing the roofs of Type 3 construction buildings over at Firefighter Toolbox. He’s already covered using the roofs of adjacent buildings and ladders. Today, Hayowyk wraps up his series with one of the most dangerous and least desirable ways to access roofs: fire escapes.

This article covers choosing which fire escape to use on a building, sizing it up, climbing it safely, getting your tools to the roof, and then climbing back down. Oh, and if you’re not checking out the fire escapes in your district on a regular basis, both for yourself and for potential victims, then you just don’t get it.

We’ve posted a lot about roof ventilation here, including how to size up roofs, how to carry your saw and start it safelyhow to make safe ventilation cuts in flat roofs and peaked roofs, not to mention all the other things you can do on a roof. None of that’s going to do you any good, though, if you can’t get up to the roof.

This Firefighter Toolbox article – the first of a three-part series by Lt. John Hayowyk, Jr. of the Passaic, NJ Fire Department – tells you how to use upwind adjacent buildings to access the roofs of Type 3 or “ordinary” construction buildings. We’ll be following this series as Hayowyk covers roof access via ladders and fire escapes.

Tip o’ the hat to Christine Sarracino.

How to Control Dust when Cutting Concrete, by Concrete Network

How to Cut Safely with a Diamond Blade and Handheld Saw

Controlling respirable crystalline silica dust can prevent lung conditions like silicosis, COPD, tuberculosis, and lung cancer. The best way to do that, aside from wearing a respirator, is wet-cutting. However, wet-cutting has disadvantages: it’s messy and not suited for indoor cutting, not all saws are equipped for it, and cutting sites don’t always have access to water.

Using a vacuum to control dust is less preferable to wet-cutting, but it has the advantages of being easier to set up and clean up. This video from ConcreteNetwork.com showcases three kinds of vacuums, from Shop-Vac-type vacuums all the way to HEPA filter-equipped monsters.
