Oxygen and acetylene mixed in a ballon will produce a very large explosive bang when lit and a loud noise and gratifying plume of putrid black smoke. Hydrogen and oxygen is going to be many times more explosive, not sure how many times more though.

Police Scotland established Specially Trained Officers in 2018 who work in local policing divisions and are available as a specialist resource to be deployed with a Taser, if necessary.

If you've reported domestic abuse, rape or sexual crimes to us, we'd appreciate your feedback on the service we provided.

Is hydrogen flammablewithout oxygen

The trick behind this is in the ratios. As Hydrogen will burn on top, air will be sucked in at the bottom. As long as the mixture has not the right ratio, it will not explode but just burn at the top. Once enough oxygen has entered it will ignite the whole thing and do a phenomenal bang. The experiment is pretty safe.

Hydrogenexplosive limits in air

So bottom line start very small with these kinds of experiments and be aware things can and will go wrong so always take as much precaution as you can.

The key function of the group is to act as a critical friend to advise on the impact Taser may have on their areas and how that might be mitigated.

They might not know the age or history of that person. Officers still have to quickly deal with the circumstances presented to them. The priority is removing the risk anyone presents to themselves or others.

Police Scotland set-up a National Taser Advisory Group and met for the first time in February 2022. It contains a number of groups representing areas of the community such as disability, mental health, children’s rights and human rights.

Officers use a UK-wide decision making model on a daily basis to help them assess whether any use of force might be required, so that consistent thought process and model is always being applied. We want officers who will calmly assess a situation and think carefully before considering using Taser.

Police Scotland support those who wish to become police officers, special constables or police staff by hosting various online and in-person recruitment events throughout the year.

We recognise the importance of de-escalating a situation, so we differentiate use into individual types: drawn, aimed, red dot, arcing or contact mode. Discharged is when the metal probes are fired from the device.

I was on the back of a flat bed truck with a parade display and a weather ballon on a string about 10 feet above the tray (possibly less was twenty years ago) was accidentally ignited (not by me!) and a few of us were knocked to the floor/truck tray and the closest person had open flesh burns all the way down his arm which was extended in the air towards the weather ballon (may have even been holding a party sized ballon with acetylene as he was lighting them while holding them which is very dangerous and I in no way endorse (he was a lunatic this guy and I had no authority over him)).

A. Taser can be a useful tool to protect people from violence or threats of violence. Other more traditional use of force methods such as baton strikes and prolonged physical restraint can lead to injury to both the person and officers. Any use of force must be fully justified and proportionate to the threat faced.

I want to electrolyze water to get oxygen and hydrogen. I want to mix them in a regular balloon and ignite it. How much hydrogen would you need in a 2:1 ratio with air for it to be dangerous? Is this generally a safe experiment?

Place the container on a stable, nonburnable table/ bench. Have a lighter ready. Now open the top hole and ignite the hydrogen gas. Move away from the experiment. After a while you will hear a phenomenal boom (make sure you have your mouth open). Do not try this in a small room.

Police Scotland has a duty to protect life and ensure the safety of police officers and the public. Police officers carry Taser as one of their options to protect people from violence.

Is hydrogen flammablein air

Now while the explosive limits of hydrogen in air range from about 18 -- 60 % the flammable limits are from 4 -- 75 %, in oxygen the limit of flammability goes all the way from 4% to 95% read: for practical purposes, hydrogen in oxygen is always at least a flammable mixture. For comparison, gasoline in air is flammable roughly between 1.5 - 7%.

All uses are reviewed and if it’s fired, it will be reported to the independent Police Investigations Review Commissioner (PIRC).

Taser initially generates around 50,000 volts of electricity, mainly to allow the wires to pass through the air and through clothing. Once it makes contact with somebody, it drops to 1,500 volts delivered in extremely short pulses.

Is hydrogen flammableor explosive

The nature of policing means officers often respond to dynamic, fast-moving incidents where information is limited and time is critical.

The most important point presented above is, in my opinion, the explosive range of hydrogen mixed in air. It is uncommonly and dangerously large!

A. The normal reaction of a person exposed to the electrical discharge of a Taser is the loss of muscle control which can make the person fall to the ground and stop them from causing harm to themselves or others.

It can stop the person moving, allowing police officers to remove the threat the person is posing to themselves or others.

Relatedly, if you enter a room and smell natural gas, do not touch that light switch! Either leave immediately or turn off the power to the house and then open windows and such. Why? Because opening the window impacts temperature which could trigger a thermostat to turn on the heating/cooling system (possible spark or flame).

SJCAM's body cameras for police are typically small, lightweight, and durable, making them easy to wear for extended periods.

Jan 24, 2023 — With a maximum range of 45 feet, the TASER 10 creates more distance for officers to de-escalate and resolve conflicts.

Here is a neat experiment, but it unfortunately needs a welder to make the equipment, a metal sphere with a volume of about 100 mL. It should have a very small opening on top and a larger one on the bottom. It also needs feet to stand.

How explosiveis hydrogencompared to gasoline

First, close the hole on the top of the container and place it in the bucket under water until it is completely full. Now you can fill the container with hydrogen gas until all water is gone from it. When you remove your container, make sure that the bottom hole stays on the bottom. As Hydrogen is much lighter than air, it will be trapped inside.

First, let me say that I've enjoyed many times exploding soap bubbles of about one milliliter filled with hydrolysis gas. That is 1 cubic centimeter. That will give you a sound that rings in your ears in a decent sized living room. You may wish to use ear protection for the experiment.

Originally, Taser was only carried by firearms officers. Assaults on police officers have increased and officers need to be provided with additional tactical options to better protect them and the public.

The metal container should be capable of some pressure, because the gas will explode inside and you don't want to hurt anyone. Additional you need bucket or bowl filled with water and hydrogen gas.

Officers will use their communication skills and assess an incident before deciding whether Taser is appropriate as a last resort. Taser is only discharged in 15 per cent of uses.

However, you start with a stochiometric mixture which is ideal for explosion (after all, that's why you do it, right?), and it is in oxygen, not in air. So even if you "only" have a flammable mixture reaching an ignition source (e.g. electric switch), chances are quite high that as the ignition proceeds through the mixture, it can reach a zone where the gas/air mixture is explosive. Also, because hydrogen is so much lighter than air, it tends to accumulate under the ceiling, so even if there is enough air in the room that an ideal mixture would not be explosive, chances are that there is an explosive layer of gas. (Same with gasoline or, practially more relevant: solvent from glue for parquet floor tiles)

Real world point is, for example, I would NOT recommend recharging your fuel cell car in your garage! Accumulation of odorless and colorless H2 in a room followed by ignition from a spark from flipping on the light switch is a potential disaster for you, the car and the entire house!
