People Share Little Known Facts That Could Save Your Life


Random bits of knowledge may seem pretty useless most of the time, but you never know when they might be useful.

Reddit user u/clomsyclose asked:

"Reddit, what's an "unknown" fact that could save your life?"


Probably said already but....bad CPR is better than no, even if you're unskilled. You literally cannot make the person more dead, as being dead is what predicates CPR.

If you have a puncture wound to the chest or abdomen, the first thing you should do is place a non porous(think plastic bag) object over the wound, it will help prevent tension pneumothorax.

A tourniquet is quite simple to put on and can save a life if there is no other option. Place close to the site or near (not on) a joint. NEVER remove a tourniquet once placed, as clots can travel to the brain and lungs. Also mark the time you put it on.

If you're at an accident scene and have no medical training, something you can do is collect information and help calm victims. This is quite helpful as it assists the paramedics with triage and keeps potential injured persons heart rates down. Alternatively, learn how to hold C-spine.

If your car ever gets stuck on the train tracks, look for a sign on the crossing arms, this is the "railway 911" and has a number to call to stop traffic as well as your exact location.

If you've been cut deeply pack gauze into the wound as tightly as possible then hold pressure.

If you are driving in inclement weather pay attention to truckers, they are often warned ahead of time of wrecks and things due to their radios. Also never drive in the rain without headlights!!



This is a New Zealand specific one, but all emergency numbers work here. The official number is 111. But 999,000,911, etc. will all work. This is so that tourists can still reach emergency services easily.



If you smell a fish smell in your house (some people also report a urine like smell) for no reason, 9 times out of 10 it means there's an Electrical Fire.



If you either

a. have a longstanding alcohol problem,

b. show any signs of alcohol withdrawal when you go too long without drinking

Do not attempt to quit drinking without medical assistance. Alcohol withdrawal can be fatal.


And if you can't or don't want to use a rehab, ask your doctor to help you. They are more than happy to assist you tapering off and dry up safely. So many people don't know how dangerous alcohol is. My dad nearly died twice because he tried quitting by himself.



If someone is stabbed or punctured by a sharp object, leave it inside.

Do not – absolutely do not – try to pull it out! Leave the object in until help arrives.

Pulling it out will only double the damage: the object can considerably reduce and stop the flow of blood by exerting pressure on the injured area. The moment you pull it out, blood flow is likely to increase.



If you are being followed by someone, the best chance you have at deterring the person pursuing you is to turn around and yell firmly at them "What do you want!" whilst getting the best description of their face. This will help people that are around you know where you are whilst hopefully scaring the creep off as they will most likely realise that you have seen their face and know that they are following you. To make sure someone is following you, take a few random turns (avoid alleyways and dark areas, try to get to populated spots) and if they are still there go for gold.



Rescuing a drowning person can be just as dangerous as drowning. That drowning person is completely panicked and has only one goal: get air down air pipe, and a desperate drownee will do ANYTHING to obtain it: that includes climbing on top of a perfectly able swimmer and submerging them underwater to get their own head above water.

Know your limits. If you yourself are a poor swimmer or the water conditions aren't favourable (strong currents, rough waves, murky water), don't attempt rescue. Immediately contact emergency services and throw something that floats at the drowning person. If you do feel confident to perform rescue AND the water conditions are favourable to your abilities, make sure you take something that floats with you so you can immediately hand it to the drowning person before they latch onto you. If they attempt to make a grab at you, immediately kick away (feet should be pointing towards to the victim), and thrust the flotation aid at them. If they still attempt to grab at you, keep kicking away until they calm down or even pass out. Better only 1 person to rescue than 2.

Trying to punch a drowning person is completely outdated and not only further endangers the person you are trying to rescue, but puts you at risk as well. As current and trained lifeguards have already commented: if a drowning person grabs you, swim down further underwater until they release you. Remember the only goal of a drowning person is to be able to breath and stop water getting in their lungs. If you are pulling them underwater with you that goal can't be achieved and they'll let go of you.



If you get kidnapped try to leave as much traces of yourself behind as you can. For example leave bits of clothing behind or scratch your arms a lot to leave dead skin behind. This way you increase your chances that a search dog could pick up your sent and find you.


If someone's trying to kidnap you, your chance of survival drops by 50% once you get in a vehicle and even more once you reach a destination.



Never give an unconscious diabetic insulin. Please. It’s quite likely to kill them


Yes, this. I'm a type 1 diabetic and that's the last thing you'd want to do.

If a diabetic is unconscious and it's due to the diabetes, it's because of low blood glucose. Insulin is used to lower blood glucose as usually that's what the body naturally does, but for diabetics it's not the case.

The right thing to do is search whatever they have with them as they'll likely have a red plastic case which resembles a small pencil box (picture below) Inside will be a syringe and a vial with a white substance in it (picture also seen below). You want to inject the syringe into the vial, empty the contents of the syringe into it, remove the needle and shake the vial violently (but be careful not to drop it), reinsert the needle and draw the contents, and finally inserting it in the back of their arm (the tricep area) or next to the bellybutton on either side, whichever is easier to get to.

Edit: I was unaware of this, but you can inject the syringe though clothing, so the butt and thighs are also good spots for injection.

2nd edit: Diabetics can be unconscious due to hogh glucose, but if you're in a situation where you are unsure if they are high or low, it's safer to assume they are low and use the glucagon as the majority of the time it is due to them being low. I just thought I should add this just for information's sake.



That whole waiting 48 hours to report someone missing is total BS. If someone is missing, especially a child, report it asap. Make sure your family knows, and it could save your life.



It's hard working in customer service, especially with irate customers. You need to be able to empathize and understand where your customers are coming from, show sympathy, and be willing to help them with their problem. However, if they come at you ranting and raving about an issue which clearly has nothing to do with you, well, then you're free to rant about them on the internet.
