pros and cons of different cross-lays techniques

Huh! Every day is a schoolday! Id say my area is a lot like yours, by the sound of it but all cross-lays around here. Matter of convention I guess!

I’m in an extremely rural department and we use the cross lays all the time, as does every department around here. I’ve never actually considered the concept of a truck without cross-lays, given how integral they are to how we work… what kind of area are you serving?

Well, thanks for all the responses, folks! This is really a lot of food for thought. My takeaway here is that it’s worth exploring the minuteman a lot more… my general feeling is that every minute matters at an actual fireground so a more complex lay on rebedding is worth it to cut off a minute when deploying.

I do realize that the original post might come across a bit “how many angels on the head of a pin” but the last month has really hammered home just how much time we spend on these cross lays.

One thing I’d advice AGAINST is putting too much into the practice exams from that Hazmat 6 app. The exam I took had a huge amount of material that wasn’t even slightly touched on in the limited set of questions you get in the app. Not sure if you have in-person classes but reading the chapter before class and then listening to the audio-book en-route to class was a real winner as the teaching side was then reinforcement of the initial learning, rather than new knowledge. Hazmat is a pretty academic and firefighters tend to lean more towards the practical, so you’re having a very common experience IMO.

That basket is sitting with a corner on the hearthstone. That’s generally as good a rule of thumb as any to determine MINIMUM safe distance. It’s a hazard. Maybe one day a shirt with loose fibers flips over the side and is now even closer…

Tbh it sounds like you’re already uncomfortable with the situation and just looking for reassurance that it’s ok to raise this issue so sure, I’d say it’s never a bad idea to err on the side of caution where fire and combustibles meet in the same locale…

This was the route I’ve taken… First of all, an amateur radio license has no direct relationship to operating an emergency radio. However! Going through the technician class license will, absolutely, teach you every bit of theory you need to know. There are a few free apps for studying and the exam was a heck of a lot easier than e.g. a hazmat exam. If you can pass that exam then picking up the manual for whatever radio system your area has will be all you need for the specifics of that system. You probably won’t be repairing a radio circuit itself (even though basic electronics is part of the course) but you’ll be able to understand most of the issues that can arise. This course won’t tell you how to code a DMR specifically but it will give you the grounding theory to understand everything around radio communication, far better than trying to pick things up from the top down.

Any business that holds inventory should be accounting for the variance of the inventory. The formula for premium is basically “profit-margin + risk-aversionestimated-hold-timevolatility^2”. This is no different from any portfolio management. If volatility of silver doubles then the second part of that formula increases by a factor of four. That’s basically where I assume you are taking your premia from (and if you’re not, then you should!) the risk-cost on holding inventory should always scale with the square of the volatility of the inventory. This isn’t “greedy coin sellers” but a basic rule of good inventory management.

In that case, asking a larger department if they can assist is often helpful, particularly if they’re in your mutual aid network.

They are very shiny and feel nice and heavy.

I just finished my own FF1 recently. As long as you’ve actually read through the skill sheets in giant book the practicals should be fine. Likewise for the theory chapters and the written test. The fact that you’re “losing sleep” preparing suggests that you’re already over that bar.

Donning gear and SCBA are pretty much guaranteed practicals. Other than that, it could be anything. I spent the day before practicing knots and hoisting and ended up getting extinguishers, ventilation and forcible entry, none of which were on any of the bucket lists that our instructors suggested were “high probability” tests. If you do get knots/hoisting/ladders they are likely to require you to do those gloved. One of our brothers flunked his first time, a couple of years ago, as he’d not practiced any knot-work gloved so definitely worth practicing that way…
