Static ropes are used whenever you're working with a static load, either raising or lowering. Dynamic ropes should be used whenever there is potential for a fall and high impact forces. Static ropes are used for rappelling/abseiling, ascending, hauling, rescue work and making anchors (accessory cord). Pretty much they are to be used in every situation ...

If you're not a climber, then don't buy a climbing rope for doing roof repairs. If you're going to buy a rope for a very specific job, then you should get the right equipment for the job. For about the same cost as a climbing rope you could get a full roofers kit that comes with a: 5 point safety harness 50ft lifeline anchor plate 3' shock absorbing ...

No, it is not safe to burn just any kind of wood, because some woods contain toxins that have the potential to be fatal if inhaled as ash (poison oak, poison ivy). However, most wood found in nature is safe. There's no such thing as smoke that won't cause damage to the lungs, smoke is a particle, your body has many levels of defense to try and prevent ...

You shouldn't inhale too much smoke. Everything which is (or used to be) alive is mostly carbon, and whenever carbon burns, you get carbon-monoxide which is poisonous. Symptoms of acute carbon-monoxide poisoning are: Dull headache Weakness Dizziness Nausea Shortness of breath Confusion Blurred vision When you have these symptoms while spending some time ...

Always surface dive/snorkel first. I have cliff dived in two locations - one is normally deceptive: poor visibility, shadows etc but on visual checks turned out to have 100 ft straight down to a sandy floor; the other looked clear and deep but had rocky ledges at about 20 feet! Considering we dived from 80 - 100 feet, that second location was scary! ...

While there are slightly different needs (on your roof you are likely to get more friction against edges than a climber) for most purposes you can use perfectly normal climbing ropes, and a standard figure eight knot to connect to your harness. However - you should be equally as interested in how you will use the rope. Do you have an experienced belayer? ...

This is not a survival technique. The way to determine how many calories is in a particular food item is to measure the amount of heat energy emitted when an item is burned. Anything burned to ash is basically calorie free as far as food value goes. Ash is composed of whatever was unable to vaporize into smoke in a fire. The hotter the fire, the more ...

To answer the third question: Charcoal is basically wood (technically any biomass, but it's usually wood) that has had its water and other volatile components completely removed, leaving pretty much a lump of almost entirely carbon. Charcoal compared to wood is similar to comparing distilled, concentrated alcohol to sugar cane. The charcoal burns ...

Pressure treated wood is especially toxic, since it contains chemicals meant to preserve it and kill things that would destroy it. Never burn pressure-treated wood. Other answers covered the rest pretty well.

Where I'm from the water is clear enough for you to simply look over the edge and visually check if it's safe, you can see at least 30-40ft deep sometimes if not all the way down to the bottom. The occasions where you need to check depth around here are when you're by a waterfall and your vision is obscured by all of the bubbles. Swimming around the bottom ...

In addition to ShemSeger's excellent answer: Try hanging in the harness in a safe spot and think about how you will be rescued if you fall. Hanging in a harness might be disabilitatingly painful. Some people loose consciousness within minutes of being suspended (https://en.wikipedia.org/wiki/Suspension_trauma), and there are many deaths on record, in ...

Bear bangers and bear spray are designed for slightly different situations. Bear bangers are intended to use when a bear is still a ways off, but is showing no signs of leaving, or is wandering towards you. The idea is to scare the bear off before he gets close enough that you need to be seriously worried. They generally shoot a few hundred feet. Looking ...
