Emergency - Gas Fire!
Woooooooo??Woooo???The siren sounded. All of us looked at each other with excitement. The time has come for us to go into action. From all over the building, we can see Emergency Response Team members coming out, some looking a bit dazed. A general alarm had been sounded and the ERT has been activated! At the command post, the "Commander" quickly briefed all the ERT members about the situation. There was a fire at the LPG storage tank, and there was an urgent need to put out the fire before the tank becomes so hot and pressurized that it explodes. Very serious and widespread damage will certainly occur if that happened. So all the ERT members swung into action. From the command post, they ran all the way to the LPG area. One member was assigned to the fire pump house to take care of the fire pumps. This type of fire needed a tremendous amount of water to cool down the tank. A few members barricaded the area leading to the fire. This was necessary to ensure that the scene of the fire be restricted only to people who are able to help, to ensure that the fire brigade has free access, and for controlling the crowd. As the ERT members reached the scene of the fire, the Commander directed the operations while keeping in touch with one member who was assigned for communications work at the command post. The Direct Attack Team swung into action with their hoses. There were 4 persons in each hose team - the first nozzle member, the second support, the third runner, and the fourth hydrant valve operator. Each member played their part to make the hose connections, operate the valves, and advancing as smoothly as possible. The LPG fire need to be extinguished - but not by the water. Extinguishing the fire in this way will create another hazard. If the gas were to escape unburned, it could be more dangerous. Any spark later on can ignite the gas and cause a bigger fire, possibly causing a tremendous rush of expanding gases. So the hose team have to try to approach the fire in order to close the gas valve. That will stop the fire and the escaping gas. There were sufficient people to operate 3 hose teams. While one team approach the flaming area with a water-wall spray, another two teams directed the water to the top of the LPG tanks with water jet for cooling. After a while, it was discovered that there was a casualty. Somebody has been overcome by the smoke and has fainted. He has also sustained a fracture on his arm. The first aid team was called in, and they rendered first aid to the victim. Within a few minutes, the fire was put off, and the building was no longer in danger. Fortunately, this was not a real fire. It was just a simulation, using real LPG gas and burning in a controlled manner. This was done to give the ERT members some feel of the real thing, to check on our readiness, coordination, and skills so that they can improve and develop their actions. This type of simulation was very beneficial to the ERT members as it gave them a first hand knowledge of what to expect in an actual situation. Think safety...

Emergency Disaster Planning: Building a Bug-Out Kit Report after report comes in about how many people couldn't or didn't escape the wrath of Hurricane Katrina. More reports come in about the disorganized relief effort, the communications problems they're having and the difficulty in getting survivors to safety even when they are reachable by rescue personnel. Tips for Keeping Your Home Invasion Free Home invasion formerly known as burglary is the type of crime that you can do something to prevent. Home invasion falls into two categories burglary and robbery. In my book "Crime Awareness 101" I discuss the differences of both and what you can do. In this article I am going to address preventative steps to protect your home from being unlawfully entered. What is home invasion? Home invasion is where someone enters a dwelling with the intent to commit a felony, larceny (theft), or assault. In most cases these criminals look for easy opportunities or in other words look for the path of least resistance. In fact it is stated that statistically a home invasion criminal will not at the most spend more then two minutes attempting to break into a home. By understanding this, your best defense is to create a path of great resistance. Here some suggestions to securing your home. Alarm System: Wireless Remotes WIRELESS ALARM SYSTEM REMOTES Home Security System, You Are A winner Have you ever been to a local trade show or fair and filled out a raffle and later you find out you have won a Home Security System? Well, you are not alone. Sometimes everyone one wins. That's right you are not as lucky as you think you are. Well you are lucky in one regard; home security systems do work, not only do the little flags out front of the stickers near the front door help prevent crime, but an alarm sends the culprits running big time. Emergency - Gas Fire! Woooooooo??Woooo???The siren sounded. All of us looked at each other with excitement. The time has come for us to go into action. Hurricane Preparedness If you are about to get hit by a Hurricane are you prepared? Do you have enough plywood to board up your windows? Often the local lumber companies will be sold out. In fact if you wait till the last minute Home Depot will be out too. Do you own a portable generator? No? Get one. Do you have enough fuel to keep it powered up? Most generators can use up to 1.5 gallons per hour and thus you need spare fuel tanks as well? If you wait too long the gas stations will be closed and after the Hurricane the power may not be turned back on for up to two-weeks depending on the damage. If you are talking about a direct hit Category III or IV it is entirely possible that it will be at least that long. Surveillance Camera Positioning It is a known fact that advertising is made to attract our eyes. Marketers work very hard to plant visual memories in your mind. They use anomaly phrases, rhetorical questions, sexy images and ironic text. There are many reasons why this is done but the biggest reason is that it works. Our eyes are often caught and our brains captured for a moment while we digest the advertisement. Since the advertising world has done such a good job in making us look and think there is a slight hesitation in our gaze and direction of sight. This of course is the world's best time to snap a shot or grab an image of a human on a surveillance camera. Security Alarm System Motion Detectors Passive Infrared Motion Detectors- These detectors are also known as PIR detectors. The technology they utilize is "passive infrared". The device is mounted on a wall or in the corner of a room. It sends invisible fingers out into the covered area in several layers. The top layer goes the furthest and averages about 60 feet straight ahead and 35 feet on the sides. The Real Desire for the UK House Buyer Location location location, central heating, air conditioning, double glazing, good neighbours,good schools and a long lease these are just some of the factors that buyers consider when buying a property. So it was some surprise when we learnt that that new UK research (Jan 05) commissioned by the Homebuyer Show revealed something completely different. Protect Your Family From Solar Flares Protect your family from solar flares. Solar flares emit dangerous gamma radiation, which affects everything from gravity waves to the Earth's tectonic system. These solar flares are dangerous to human life. The Gamma Radiation is dangerous to the human bio system. Many severe solar flares can cause cancer and It heats up the atmosphere and can drastically change weather patterns too. We have had some serious solar flares in the last few years, which have affected our lives. Some say that Earthquakes are in part due to the disruption of the natural electromagnetic distribution of the Earth along with causing disruptions in gravity waves. Garage Door Openers--Buy the Best Gagage Door Opener only Buying the right garage door opener has not never been more simpler.Whether you want to buy one for residential use or the commercial use read the tips below and buy the garage door opener which ideally suits you . Alarm System: Glass Break Detectors Alarm System Glass-break detectors- Glass-break detectors are also known as "Audio Discriminators". They are a perimeter device because they catch a burglar attempting to make entry into your home or business as opposed to walking around the interior and being picked up by a motion detector. They are available in both hardwired and wireless versions. The detector mounts in a wall or ceiling and listens to an area approximately 35 feet in all directions. They do not hear through walls or around corners or into a room because the door is open. The more windows you have in a device's area of protection, the better the value. Some examples of good coverage are as follows. Who Has Keys to Your Castle? One area of home security that is often overlooked, and one of the most visible, is the common key. Even if you are the owner of a new house, or the first tenant of your apartment, you cannot be sure that no one else has a key to your door. Handling a Hurricane; Part 2 - Preparing for and Surviving an Approaching Hurricane Part 1 of this article described some of the characteristics of hurricanes and the damage they can cause. In the days before high tech weather forecasting, well organized emergency services, and mandatory evacuation, major hurricanes resulted in hundreds, if not thousands of deaths. Who Abducted the Missing Child? What is going on with these people who feel they can walk onto your property or in front of your home and abduct your child? If those parents had installed a hidden camera in their home, the police could use the recordings from the camera and have a quick lead to find the child and return them safely. Being prepared for the unthinkable act of your child being abducted by installing hidden cameras is much better than wishing later you had installed cameras! Home Security After An Earthquake After an Earthquake you need to do an immediate damage assessment. First go turn off the gas if you smell anything, a leaky gas line could explode and take out your entire home and your cats nine lives. Look for cracks in the slab or any areas where the house carpet is lifted up. Then walk around the exterior of the house, what do you see? Do you see downed fences, retaining walls, support structures holding up the garage at weird angles or any areas where your house was knocked off its foundation? Look also for water pipes which have been broken, if so shut off the main water line coming into the house. If there is extensive damage then that means the other neighbors have also and the entire area. Handling Weather Emergencies: Part 2; Home Security, Evacuation, and Emergency Kits Introduction Where Does Safety & Security Begin? Security Expert Explains Personal safety begins with you. It is widely accepted that a wide-ranging personal safety strategy must incorporate prevention, deterrence and defiance. Eavesdropping and Counter-Measures: Technology and Techniques You need to know how to protect yourself, since your security department or any consultant may not be truly aware of these threats and therefore not dependable. Since September 11th, a number of businesses entered the security field with little to no knowledge of the trade itself; only of its profit potential. Even outfits that have been around for some time and well-established have not been able to stay current with the latest innovations. Realistically, viewing your threat level has to be considered since everyone should expect some sort of impending privacy issue no matter how small. Thanks largely to the Internet you can arm yourself with much of the knowledge and equipment that the so-called experts use. If a respected agent of computer crimes for the Secret Service in NYC had his T-Mobile Sidekick hacked, who knows what else happens out there to others in any business.

If a respected agent of computer crimes for the Secret Service in NYC had his T-Mobile Sidekick hacked, who knows what else happens out there to others in any business. We'll start acoustic ducting evaluation is the inspection of air ducts, baseboard heaters, coffee rooms, lounges, bathrooms or any way the architecture of a building can transfer sound. A simple example is to put your ear to a wall and listen. Basically anything that requires the use of the naked ear is called an acoustic bug. Softer surfaces can help muffle sounds but there are more efficient means out there. So be aware that the way an office site is designed can act as a conduit for conversations. Also, be aware of any changes can have adverse affects. Simply playing music can do wonders for masking conversations. Inspection of telephone equipment and wiring is called line analysis. This is trickier than it seems since sometimes a possible weakness has an actual purpose to the telecommunication system. Especially if it requires constant maintenance and software upgrades. All instruments should be opened and inspected. Ideally they should be compared with a known safe phone or device. If you're not sure, just remove that piece of loose components and wiring and see if the phone still works. The wiring can be modified in a switch within the handset that essentially turns it into a microphone. If you bypass this hook switch, you can listen in from anywhere on the landline. Technical equipment won't be able to detect this. Time Domain Reflectometry is the sending of a pulse down a telephone line. If there is some sort of disruption; a wall outlet or wiretap; a portion of the pulse will be sent back to the device called a Time Domain Reflectometer (TDR). Then the time difference between the reflection and the continuous run is measured. This helps in determining the distance to the anomaly. These devices can perform all sorts of diagnostics including mapping a wire network. That can be useful in locating a hidden phone. Hidden phones have several obvious uses such as making long distance phone calls to being placed in an office across the street to receive betting requests by bookies; a practice called back strapping. If you open up the modular jacks where you connect your phone, you'll usually see four wires. In most cases only two wires are connected; commonly known as ring and tip. If you see all four connected, be aware that is not usually consistent for most wiring situations, especially in homes. The other two wires could be used for a bugging device. For instance, the microphone you use in a voice recorder can be cut in half. Connect the mike head to one set of unused wires anywhere on the phone wire. Then, so long as there are no breaks in the wire, connect the other end to the jack that connects to your recorder. Now place your recorder to be VOX (voice) activated and now you have an extremely reliable bug. By the way, this should be manually inspected for since using a specialized bug detector may see nothing wrong or inconsistent. A bug such as this that connects to a wire is called a direct tap. The other general type is called an inductive tap. This is when an instrument is outside a wire but can still distinguish what's transacting over a wire. They are harder to detect since they don't draw power from the line such a standard telephone would. These are referred to as snuffle bugs. A simple probe used in hunting wire signals has a speaker, which can display sounds. By accident one day I was working on an apartment intercom system while using a probe. I could hear conversations throughout the building quite clearly just through the intercom boxes mounted on walls from the master unit in the basement. If you're using wireless headsets or cordless phones, the radio signals can be intercepted. A cordless phone acts like a radio, but depending on the frequency and a few other factors, can make interception extremely difficult. With some manufacturers, you can buy the same model as your neighbors or the office and have it join their phone system. Double check Caller ID boxes to see if they also record numbers dialed besides obviously those being received. If you're using VOIP (Voice Over IP), remember that calls can be recorded in a fashion identical to intercepting data between two computers. These packets of data can reassemble an audio file. Obviously electronic devices possess semiconductor components such as diodes, resistors and such. The method to hunt for these components is called Non-Linear Junction Detection (NLJD). The NLJD unit emits a radio signal while listening for the return signal from an electronic device. This becomes very useful when a bug is embedded in a picture frame or wall. The eavesdropping device doesn't have to be active for it to be discovered. If a device is active and transmitting wirelessly (or even on a wire), you can detect it with a Radio Frequency Spectrum Analyzer. Depending on the detection device used, you can determine whether voice, data or video is being sent, and possibly listen to the data. Try to use different size antennas or buy one that collapses. Different frequencies can be detected more efficiently by using various sizes. The use of filters with antennas can also help pinpoint devices on specific frequencies. Electronics such as computers, FAX machines and especially CRT monitors can radiate electromagnetic signals or pulses that can be received by other equipment. This is known TEMPEST. One way to complicate the surveillance of this is to use certain fonts and line walls or equipment with different gauges of copper mesh wire. You can further enhance this posture by using special paints, which block radio transmissions. Radio waves will look for a leak or break, so be careful of defensive applications. One-way window tints can help in blocking signals. Since an electronic device could generate some heat they can be detected in another way. The use of a thermal imagery device can detect and actually see minute amounts of heat radiated for your viewing. You can hide the heat signatures by using creams or neoprene. Technology exists to collect information from blinking LEDs of modems, routers, print servers and similar devices. You can only see some general blinking but with the use of properly tuned optics, filters, oscilloscopes and good timing you can discern much more. One of the LEDs on your keyboard can be altered to blink while you are typing in a fashion similar to Morse Code. You can also use a tap in the keyboard that sends out radio waves again similar to Morse Code and no anti- virus software will ever be able to find it. Even when a CRT computer monitor is facing a wall the light can be in a sense read by its flickering emanations from some distance. A good defensive measure is to buy new LCD flat panel types. Another approach to attacking FAX machines is to simply record the noises it makes and play it back to another machine. I used to do this for a client so they could keep a record of all the faxes they made and received. There are creative and potentially illegal defenses against wiretappers and Peeping Toms. One is to transmit an extremely high pitch down the wire, thereby rupturing the listener's eardrums. I knew someone who once sent a powerful electrical spike down his phone wire thereby destroying his divorced wife's recorder. By the way, this leads to another topic-expect the device to be discovered someday. Don't leave your fingerprints on it. He found it and had it dusted, thereby producing some prints. My friend used this as leverage against the Private Investigator that planted it. Advice to Private Investigators, a word to the wise: if you do this part-time, hire someone who does this full-time. This P.I. lost his license and almost went to jail. The lawyer who recommended him got into a lot of trouble as well. He received some unwanted attention from the Feds because of his telephone dealings went across state lines and also happened to involve the Post Office. There is another budding field related to this topic called Protective Intelligence. Currently there are only a few experts who do this kind of work. A laser or an infrared beam can be used at a considerable distance from a target building. Conversational sounds can vibrate unto solid objects such as windows. The beam's reflection varies in relation to the movement to the window, which is received and converted back into something audible. To mask the sounds, you could attach a vibrating device (basically an altered electric razor) to the window. Of course if the window is open, then a laser can target another object instead of the window. A beam of light or laser can be directed to go through a window onto a solid object thereby nullifying such defensive measures again. Generally you really can't detect such attacks unless the laser, infrared or light beam is being used that moment. Certain materials can be used to detect IR emissions, as well as the use of passive night vision gear. Certain fabrics or even a curtain may actually show the spot where a beam of light or laser is being focused. Unless the room is dusty or you have an artificial can smoke, you can follow the beam up to a point and guesstimate it's location. One type of optical bug is an infrared transmitter. When placed in the area of interest for transmission of the conversation to an infrared receiver which will then translate the conversation into an audible format. Many of these same procedures used can be applied to locating hidden cameras. A relatively new device uses a series of lasers to seek out optics. This was originally intended to locate snipers by bodyguards. I have listed the techniques, counter-measures and then the counter to the counter-measures to prevent any false sense of security. Usually constant vigilance is your best weapon besides knowing what to look for. Even if you find a "bug sweeper" with good credentials, certifications and experience, ask them detailed questions. Not just to test them but also for your own peace-of-mind. This makes our job easier and we appreciate greatly when dealing with knowledgeable customers. How to Buy a Safe for Your Home The first step is to determine who or where you will buy your safe from. There are many places to buy a safe today, you can buy from a "big box store", an office supply store, a furniture store, a hardware store, online, or even from a professional safe retailer or locksmith.
