How can you protect yourself from electric shock?

Be sure the power is off before touching any electrical wiring. You can't rely on the color coding to know what wires are hot. Be sure you know what you are doing . Do not take shortcuts and wire according to code. Test your work after you finish. If you have any doubts about your expertise, hire a professional. Faulty wiring can start a fire or maybe even shock or electrocute someone.

What are chances of being in fire?

While there is always a chance, they are very slim due to current technology.

How do you secure an outward opening door?

Besides the obvious answers of steel door locks, no glass, for me, hands down is an alarm system. For years I slept with one eye open and only when I had a real scare thinking I had a fire in my basement 2 levels down, did I have an alarm system installed. Not only do I feel immediately secure when I come home, but I can sleep knowing that is anyone tried to come in or if a fire broke out, the alarm company would call the police and fire department immediately...no matter what!

Why would safety glass shatter on a shower screen?

There are a number of reasons but the most obvious one seems to be that over time the frame that supports the glass slowly tightens... perhaps one one thousands of an inch over the years and eventually you have an explosive situations. A good idea would be to replace this glass once a decade with a shatter safe type of glass. Cheers.

How do you respond to a kitchen fire at home?

In case of a kitchen fire, get the extinguisher quickly.

One of the best home safety devices is a large, thick, 100 percent cotton bath towel. Not a thin, worn one you'd otherwise throw out, but a good-quality one.

Keep this towel in your kitchen on a rail or hook; apart from being great to dry hands, comfort small rain-soaked children or pets, or mop up sudden big water spills, it should be your second response to a small domestic fire.

Your first response to a small domestic fire is to calmly but very firmly tell everybody else to get outside and be ready to call emergency. Never, ever, underestimate the speed with which fire can spread.

Now, simply hold out the towel at arms-length, keeping it as flat as possible, turn your face aside, and gently lower the towel onto the centre of the fire. This should stop the fire immediately.

If the fire is getting higher or spreading, soak the towel in water. This takes far too long under a tap; the best way to soak a towel in case of fire is to drop it in the toilet, close the lid, and flush. Take it out and flush as many more towels as you're likely to need, so you have them ready to throw onto the fire or fires, as well as to cover your face for smoke protection.

Since most indoor domestic fires are either electrical, or are happening near electrical equipment, don't use water unless you're one hundred percent certain no electrics are involved or nearby.

For a fire anywhere in the home, use your extinguisher if you have one, provided you're certain it is the right sort of extinguisher for the type of fire. If you don't have an extinguisher, or don't have the right type, use thick, heavy rugs or anything else which will cut oxygen from the fire. Never use synthetic fabrics, and never, ever use cushions or pillows, which will be filled with materials that will not only burn - and feed the fire - but will give off toxic fumes as they burn.

If your fire is clearly spreading beyond the small stage, call emergency, at the same time making absolutely certain all people and pets (in that order) are out of the house. Stay calm and be sure to give the full address and special directions, if necessary, to the emergency operator.

Most importantly: get in touch today with your local fire service and ask them for information on domestic fires and other emergency situations. They'll have heaps of information, which all the family should read and use to formulate some basic, essential, easy-to-remember emergency responses, and maybe make up an emergency kit. Kids love to be involved in this kind of thing, and it's reassuring to them to know people can prepare for bad things that probably wont, but just might, happen.

Being prepared for the unexpected saves lives every single day, and one of those lives you save this way could be your own or that of a loved one.

Why can't you shower during a thunderstorm?

You shouldn't shower during a thunderstorm because water is a conductor of electricity and it may direct the energy of a lightening bolt through your body.

And the power may go out. This might cause you to slip and fall and cause an injury.

What are the advantages of living in the country?

Combined brain power of the world over: leads to great leaps in human advancement and technology. There is a large variation and diversity of talent to be had in the world.

Large population results in overall, more immigration. This increases the mixture of races in any country and reduces the possibility of conflict and corruption between nations. The world benefits from a better sense of unity.

Greater defenses against alien invasions which may never actually happen

What is good room temperature for baby?

baby's need to be warm and that's why they need to be in a room that have the temperature 30 Celsius

Babies are usually warmer than adults--usually comfortable in one layer less than the parent is wearing, particularly in winter!

What are the advantages of having personal protective equipment?

The primary purpose of personal protective equipment is to protect the wearer from injurious contact with hazardous agents when other means of preventing contact are inadequate or unavailable.

How many volts can a human take?

16 thousand volts

The voltage isn't anywhere near as important as the current (Amps) A human regularly takes voltage sparks of 86,000 volts as found in static discharges but the current is negligible.

People frequently survive millions of volts discharge when struck by lightning. Also you have to consider that the path that the electricity takes through the body will alter how deadly it is too.

The most dangerous path is through the torso to ground through the feet. If the electricity travels this path the current would travel through the nerves that control the heart and possibly lead to cardiac arrest.

I believe that Mythbusters tested the theory of how much current it took to kill and came up with a minimum value of 300 milliamps (0.3 amps) across the heart would cause it to stop beating. (Mythbusters website episode 19 Toaster in the bath). If you are really lucky the heart could re-fibrillate again and you might survive.

<<>>

Milliamps are dangerous 1 amp = 1000 mA

Less than 1/2 milliamp no sensation

1/2 to 2 milliamps Threshold of perception

2 to 10 milliamps muscular contraction

5 to 25 milliamps painful shock (may not be able to let go)

Over 25 milliamps Could be violent muscular contraction

50 to 100 milliamps Ventricular fibrillation

over 100 paralysis of breathing.

How do you prevent and control the environmental pollution?

I really believe that we can make a solution and apply it, you know. But then most us don't really understand what are the results of doing these things to the environment, deteriorating it time by time. We can prevent environmental polltuon simply by reusing, reducing and recycling things. Disposing our trashes well to their places and disposing harmful toxics to their right places so that it won't harm our trees, rivers and of course our wildlife. :))

What is the cost to change house lock when forget key?

It's not expensive. They don't actually replace the lock. They just take it out and change the position of the latches inside of it. Then, they make a new key. I had front, back and side door (in garage) changed for $45. It might be higher or lower in your city.

How can you protect yourself from vampires?

Here's the facts sweety. YOU,

Yourself cannot kill it...

A "Werewolf" can only be killed by,

1. A hunter.

2. Another wolf.

Normally that other wolf is either its mate.

With yes they do sometimes kill there mates

or

an alpha of there pack or another.

But a simple mortal cannot kill a "Werewolf" Them selves.

_______________________________________

In human form, you can kill a werewolf the same way that you kill any human, in wolf form, first you have to be lucky enough to actually find a werewolf in wolf form, and even then it would be very hard to kill it, because it would more likely kill you than the other way around. They are very hard to kill in wolf form.

How can carbon monoxide poisoning be prevented?

What you do is buy a carbon monoxide detector, you can get them at hardware stores like canadian tire or home depot. You plug it into the outlet you'd like, and its alarm will go off if it detects carbon monoxide.

How can you protect yourself from incidents and accidents?

Try to have a soft landing.

Seriously, though, professional fighters and stunt men and women who fall all the time are trained to dissipate the energy of the fall over time and area. In other words, rather than hitting with a sharp impact on a solid object, try to make the landing last a few tenths of a second longer by rolling or crumpling or by hitting at an angle and skidding rather than putting all the force into the initial impact.

Why do we use yellow colors on the roads?

The yellow is a stark contrast to the black/grey especially at night or poor driving conditions i.e. fog and snow - In some countries they use white which can "disappear" in poor condition yet use the yellow to mark restricted stopping and parking

Are horse riders required to wear a helmet by law?

It is always best to wear a helmet, and strongly suggested if you are a child. However, the laws can differ from state to state. Log on to your state or county website and you can find out what the laws are for your state there.

What possible threats to your personal safety and well being when using the internet to communicate using IT?

As Internet use has increased, so have the ways crooks use to undermine users' safety. Because the Internet is a data medium, crooks look for "Personally Identifying Information" as their main vehicle to commit crime. With your personal information, a crook may be able to access your online accounts, including banking. With other pieces of information, they can open charge accounts, wreck your credit, or even break into your home.

Therefore, you should:

  • make your passwordS hard to guess
  • use different passwordS on each website or online account
  • never tell or share your passwords
  • change your passwords frequently
  • use caution when giving your birthdate, name, and address to any website
  • don't post personal details on Social websites
  • don't post your whereabouts on Social websites
  • use caution in chats -- don't answer personal questions!
  • don't talk about family members by name
  • don't talk about your school by name
  • don't talk about your teachers by name (people can research the teacher and find the school's name and address)
  • suspect everyone, even a "friend"
  • remember that you can "friend" a person online---but they aren't really "friends"
  • if in doubt---don't! Ask your parents!
  • Never ever agree to meet someone in person who you met online.

How can you protect yourself from gang members?

Most gang members aren't going to pick a fight with someone whose just walking and minding their own business. However, if one does happen to approach you, stay calm and relaxed. If you appear too on-guard or frightened, they'll be encouraged to mess with you. The best advice I can give you is not to fear them. Gang members only have as much power over you as you give them.

How many volts can a human take to the body without dying and how many volts would a 10 year old be able to take?

It is a combination of voltage and current flow that kills. A body can take many thousands of volts with little harm. When you draw an arc between your fingers and that door knob you just touched after shuffling across the rug on a dry day, you are on the receiving end of several thousand volts. Yes, that's how much voltage it takes to break down dry air and make it conduct. But current is low. If you happen to get "hooked up" to a car battery, the 12 volts (actually, it's a tad more on a good battery) can deliver a punishing amount of current flow. Usually our skin resistance is high enough to ward off a shock like that, but we can get a "wake up call" from the vehicular cell set if conditions are right. But it isn't a fatal encounter. It is a combination of voltage (which is the driving force that creates current flow) and the resistance of the current path, which is your body, that sets up the current flow. Actually, the "experts" often talk about a fatal shock in terms of voltage and a current flow at that voltage. Or they'll talk about current flow across the heart itself. But the body, which is the current pathway, sets the current based on its resistance. And when they apply the figure to the heart, how do we know how much current will flow there? That makes things clear as mud. Electric current must flow through vital organs to kill, and to target the heart requires a bit of "trick" wiring. Current will flow in lots of places within the body because of the high conductivity of the ionic fluids inside us. Why did you have to sit through this long-winded report on what may or may not be? Simple. There is no "dead bang" voltage that a person "can take to the body" and survive. There is a threshold voltage above which it may be possible to be fatally electrocuted. How hard can you be hit in the head with a 2 x 4 without dying? And where in the head? Same general type of question. Exactly the same. Lots of variables and no "slam dunk" for an answer. And don't blame the responder; blame the electricity. It's electricity's fault that it doesn't come in portions you can choose when you're about to be electrocuted. And it's electricity's fault you can't choose where you'll take the shock, choose what pathways the current will take through your body. Electricity makes all those decisions for you. Electricity, voltage, actually, has perfect "vision" when it comes to any and all pathways that it can drive current through. It always "sees" the possibilities. Always. And it always sees all of them. And when it can make a move because conditions allow it to, it does. It's that simple for electricity. It evaluates materials on one basis and one basis alone - can I force current flow there? And if so, how much? And it makes these decisions in the twinkling of an eye.

How do padlocks work?

There are various forms of padlock each with a different type of locking mechanism. Some are more secure than others but as a rule the two most popular are keyed and combination.

Keyed Padlocks

A padlock that uses a key will have a locking barrel mechanism. In most cases there will be tiny pins located at 90 degrees to the key as it is inserted. The key then has between 3 & 6 groves cut into it and as it is inserted into the barrel it lifts the pins into alignment. Once aligned the barrel can then rotate which causes a horizontal spring loaded bar to shorted. This is often what causes a padlock to spring the key back into its original position if released.

Diagram: http://www.nothingbutpadlocks.com/images/locks/padlock_diagram.gif

The horizontal bars lock into the loop of the padlock. This is known as the shackle and is usually made from a special type of hardened steel. Once released the shackle will spring open.

Combination Padlocks

A combination padlock uses number dials rather than a key and does not have a barrel mechanism. They are usually designed with a series of ball bearings that are aligned when the correct combination is used. The mechanism does not allow the same type of strength you would get in a keyed padlock and so are generally considered a less secure option. Combination padlocks also tend to be less reliable when used outdoors or when exposed to dirt, grit and sand.
