Forcible Entry through a Glass Door, by Brotherhood Instructors, LLC

Forcible Entry with a Glass Door, by Brotherhood Instructors, LLCYou’ve probably run across a glass door during a fire and wondered, “Why do we have to break out our forcible entry tools for this thing? Why not just smash the glass?”

That’s a bad idea, according to our partners at Brotherhood Instructors, LLC. Breaking a glass door can take longer than conventional forcible entry techniques if it has a push bar, since you have to get rid of the bar before you can use the door. You also can’t control the ventilation of a glass door once you break it, and the broken glass can cut your lines.

Bottom line: don’t break a glass door if you encounter one on the fireground. Use your forcible entry tools like the REX tool or – our personal favorite – the power saw.

When Do You Replace a Worn Out Diamond Blade?

When Do You Replace a Worn Out Diamond Blade?First of all, remember that a diamond blade is different from a knife blade or toothed saw blade. Because of this, it won’t have dull edges or dull teeth when it’s worn out. (In fact, we’ll bet that your diamond blade’s cutting segments look dull whether they’re worn out or not)

That’s because a diamond blade cuts with the diamonds impregnated into its cutting segments. These diamonds wear down during cutting, despite being one of the hardest substances on earth. When these diamonds are worn out, then your diamond blade is worn out, and you’ll need to replace it [1].

How can you tell this? Simple. Before your diamond blade is worn out, it’ll cut slower and slower and eventually won’t cut at all [2]. You should also look at the blade before you start cutting to see if the blade core has worn-out spots [3] or if the cutting segments have completely worn down [4].

Keep in mind that you can’t always gauge the life of your diamond blade by its cutting speed. Some blades will become “glazed over” if they’re too hard for the material that you’re cutting. You can usually restore these blades by running them through something abrasive, like asphalt, instead of trying to replace them [5]. In other words, the best way to determine if you need to replace your diamond blade is to look at it.
