Fire Prevention

Fire interference needs segregating the 3 parts of the hearth triangle. In observe, a way to attain that goal is to post—and enforce—no smoking signs around combustible liquids and gases and have fireplace watches on all work involving torch-applied materials of a minimum of 2 hours when the last torch is turned off.

Flammable and flammable Liquids Proper storage and handling of combustible and flammable liquids can facilitate prevent fires from occurring; solely approved, closed containers for storage of flammable or flammable liquids could also be used beneath Occupational Safety and Health Administration rules. Such containers embrace safety cans or containers approved by the U.S. Department of Transportation. a security will could be an instrumentation that encompasses a self-closing lid, internal-pressure relief and flame arrestor with a capability of not more than five gallons. cheap, plastic cans while not those options previously mentioned, like those usually bought at hardware stores or gas stations, aren't approved to be used in roofing operations. However, manufacturers do sell plastic containers that meet the Occupational Safety and Health Administration needs for safety cans.

Flammable liquids that are extraordinarily viscous, or tough to pour, like single ply adhesive, will be left in their original shipping containers. Similarly, OSHA permits the employment of original containers of combustible liquids that are in quantities of 1 gallon or less. Static electricity could also be generated once transferring liquids, gases or solids through pipes or hoses. it's necessary to dissipate this electrical phenomenon once handling combustible and flammable materials. once transferring combustible or flammable liquids from one instrumentation to a different, the 2 containers must be “bonded” along. The bonding method involves attaching a wire with alligator clips on every finish to each container. The clips should penetrate the instrumentation coating and bit metal. you will have to be compelled to score the paint with the alligator clips. To dissipate static, the instrumentation receiving the liquid should be in-tuned with the bottom and not insulated from contact with the bottom.

For example, plastic or composite motor truck bed liners forestall the flow of static electricity to ground as a result of the liner doesn't conduct electricity. The receptacle instrumentation should have a transparent path to ground, by direct contact or use of a grounding strap or wire, to effectively eliminate static.

Service or refueling areas at job sites should have a 20 BC-rated fireplace extinguisher at intervals seventy-five feet of every pump. Safety cupboards yield bigger quantities of combustible and flammable liquids to be hold on safely within buildings. Up to sixty gallons of a combustible liquid or the maximum amount as a hundred and twenty gallons of a flammable liquid could also be hold on

indoors during a safety cupboard. every cupboard should be labelled “Flammable— Keep fireplace Away.” Up to 3 cupboards could also be hold on in one area. Without a safety cupboard, solely twenty-five gallons of either combustible or flammable liquids are allowed to be hold on within a building.

Liquefied crude oil Gas Liquefied crude oil gas (LP gas) is employed wide within the roofing trade to heat kettles and torches. as a result of phonograph recording gas could be a propellant, fairly giant quantities will be hold on in comparatively little containers. As some extent of reference, phonograph recording gas expands at a quantitative relation of 270-to-1. this implies that one liquid drop of phonograph recording gas would expand to a gas state 270 times bigger in volume.

LP gas collects in low-lying areas as a result of its vapour density is heavier than air. workers ought to be warned that if they believe a leak during a cylinder, they must not use fireplace to aim to seek out the outlet. Instead, they're to use soapy water and appearance for bubbles.

Classes of Fire

CLASSES OF FIRE  -  "A", " B", "C", "D" and "K"

Fires are classified by the types of fuel they burn.

CLASS A

Class A Fires consist of ordinary combustibles such as wood, paper, trash or anything else that leaves an ash. Water works best to extinguish a Class A fire.

CLASS B

Class B Fires are fueled by flammable or combustible liquids, which include oil, gasoline, and other similar materials. Smothering effects which deplete the oxygen supply work best to extinguish Class B fires.

CLASS C

Class C Fires. Energized Electrical Fires are known as Class C fires. Always de-energize the circuit then use a non-conductive extinguishing agent. Such as Carbon dioxide.

CLASS D

Class D Fires are combustible metal fires. Magnesium and Titanium are the most common types of metal fires. Once a metal ignites do not use water in an attempt to extinguish it. Only use a Dry Powder extinguishing agent. Dry powder agents work by smothering and heat absorption.

CLASS K

Class K Fires are fires that involve cooking oils, grease or animal fat and can be extinguished using Purple K, the typical agent found in kitchen or galley extinguishers.

SOUND LIKE A LOT?

An easy way to remember these types of Fires is (beat) Class A leaves an Ash, (beat) Class B boils,(beat) Class C has current (beat), and Class D has Dense Material (beat), And don’t forget the most overlooked, Class K for Kitchen.

About the GLOBAL POSITIONG SYSTEM

About the  GLOBAL  POSITIONG  SYSTEM

Global Positioning System (GPS) is a worldwide radio-navigation system formed from the constellation of 24 satellites and their ground stations. The Global Positioning System is mainly funded and controlled by the U.S Department of Defense (DOD). The system was initially designed for the operation of U. S. military. But today, there are also many civil users of GPS across the whole world. The civil users are allowed to use the Standard Positioning Service without any kind of charge or restrictions.

Global Positioning System tracking is a method of working out exactly where something is. A GPS tracking system, for example, may be placed in a vehicle, on a cell phone, or on special GPS devices, which can either be a fixed or portable unit. GPS works by providing information on exact location. It can also track the movement of a vehicle or person. So, for example, a GPS tracking system can be used by a company to monitor the route and progress of a delivery truck, and by parents to check on the location of their child, or even to monitor high-valued assets in transit.

A GPS tracking system uses the Global Navigation Satellite System (GNSS) network. This network incorporates a range of satellites that use microwave signals that are transmitted to GPS devices to give information on location, vehicle speed, time and direction. So, a GPS tracking system can potentially give both real-time and historic navigation data on any kind of journey.

GPS provides special satellite signals, which are processed by a receiver. These GPS receivers not only track the exact location but can also compute velocity and time. The positions can even be computed in three-dimensional views with the help of four GPS satellite signals. The Space Segment of the Global Positioning System consists of 27 Earth-orbiting GPS satellites. There are 24 operational and 3 extra (in case one fails) satellites that move round the Earth each 12 hours and send radio signals from space that are received by the GPS receiver.

The control of the Positioning System consists of different tracking stations that are located across the globe. These monitoring stations help in tracking signals from the GPS satellites that are continuously orbiting the earth. Space vehicles transmit microwave carrier signals. The users of Global Positioning Systems have GPS receivers that convert these satellite signals so that one can estimate the actual position, velocity and time.

The operation of the system is based on a simple mathematical principle called trilateration. Trilateration falls into two categories: 2-D Trilateration and 3-D Trilateration. In order to make the simple mathematical calculation the GPS receiver must know two things. First it must know the location of the place is to be traced by at least three satellites above the place. Second, it must know the distance between the place and each of those Space Vehicles. Units that have multiple receivers that pick up signals from several GPS satellites at a same time. These radio waves are electromagnetic energy that travels at the speed of light.

A GPS tracking system can work in various ways. From a commercial perspective, GPS devices are generally used to record the position of vehicles as they make their journeys. Some systems will store the data within the GPS tracking system itself (known as passive tracking) and some send the information to a centralized database or system via a modem within the GPS system unit on a regular basis (known as active tracking) or 2-Way GPS.

A passive GPS tracking system will monitor location and will store its data on journeys based on certain types of events. So, for example, this kind of GPS system may log data such as where the device has traveled in the past 12 hours. The data stored on this kind of GPS tracking system is usually stored in internal memory or on a memory card, which can then be downloaded to a computer at a later date for analysis. In some cases the data can be sent automatically for wireless download at predetermined points/times or can be requested at specific points during the journey.

An active GPS tracking system is also known as a real-time system as this method automatically sends the information on the GPS system to a central tracking portal or system in real-time as it happens. This kind of system is usually a better option for commercial purposes such as fleet tracking or monitoring of people, such as children or elderly, as it allows a caregiver to know exactly where loved ones are, whether they are on time and whether they are where they are supposed to be during a journey. This is also a useful way of monitoring the behavior of employees as they carry out their work and of streamlining internal processes and procedures for delivery fleets.
