The document summarizes key elements of firefighting including:
- The fire triangle of fuel, heat, and oxygen and how eliminating one can extinguish a fire.
- Classification of fires into classes A, B, and C and appropriate extinguishing agents.
- Common firefighting equipment used on ships such as fire hoses, nozzles, foam production equipment, CO2 extinguishers, portable pumps, and oxygen breathing apparatus.
- Proper procedures for using equipment like flame safety lamps and oxygen breathing apparatus when entering hazardous areas.
Rajyog Fire Services Pvt. Ltd. established in the year 1992. The Proprietor of the company Mr. Yogesh Asher is a fire protection engineers and contractors and have experience in fire protection field for more than 25 years.
We have highly qualified & well Experienced Engineers supported by skilled & experienced erection team members consisting of Supervisors and work force who specialize in erection of fire Safety devices and related fabrication & installation etc.
The company provides sophisticated technical tools needed to safeguard lives and property from fire.
It has become more apparent over the years how important it is to have adequate fire protection in every building. For most people (Non-technical), what comes to mind when they think of fire protection are Sprinkler system, smoke detectors and fire extinguishers. However, these two elements only cover a small portion of the protection services you should have at all times. There are in fact two types of fire protection: Active Fire Protection (AFP) and Passive Fire Protection (PFP). One type of protection must not be chosen over the other. On the contrary, both AFP and PFP must be used together for full fire protection. It is important to understand the difference between AFP and PFP so that you are confident that your building is protected by both types.
Fire fighting, types of fires, types of fire extinguishers, building management systems, sprinkler systems, heat and smoke sensors.

Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.

FIRE,FIREFIGHTING & FIREFIGHTING EQUIPMENT
1. Elements of Fire:
The process combustion of fire may be regarded as a chemical triangle in its
three side consisting of fuel, heat and oxygen.
The control and extinguishing of fires in general are brought by eliminating
any one side of this triangle. If oxygen (air) can be diluted or smothered out, the
flame will go out. Its heat can be removed by cooling the fuel to temperature
below that at which it will take fire, then the fire will no longer exist. For the purpose
of this manual, it is assumed in ships that except in rare cases, it will be impossible
to remove the fuel from heat and oxygen in order to put out the fire.
Oxygen comes from the air that we breath. Air consists of 21% oxygen and
79% nitrogen. If oxygen can be diluted below 15% fire will be extinguished.
HEAT
There are three stages of temperature relative to ignition of a material
namely: Flash Point, fire point and ignition temperature.
1. Flash Point – is the temperature of the substance at which it will give a vapor
sufficient to form an ignitable mixture.
2. Fire Point – is the lowest temperature at which vapors being given off-by a
material can be ignited and will continue to burn.
3. Ignition Temperature – is the temperature at which the vapor being given off-by
a substance will ignite spontaneously in the air.
FUEL
Any combustible substance which will burn when heated to its ignition
temperature.
The importance of the spread of fire to all fire fighting operations cannot be
over emphasized. Fire grows as fast as they can develop a fire temperature in the
surrounding material.
Before a fire can be successfully extinguished, its class must be identified so
that the proper extinguisher will be used.
The following chart is a sample of classification and corresponding
extinguishing agent:
