Essay on fire hazards

These materials oxides, hydroxides, hydrides, anhydrides, alkali metals, phosphorus, etc. This is valid also for the vapours of liquids. Storage containers are generally required to contain the application of overpressure relief devices.

This phenomenon is in most cases due to the faulty construction of joints or to unworkmanlike installations. There are two means of protecting against the consequences of electrostatic charging: Spontaneous ignition of liquids is also promoted if they come into contact with air on solid materials of large specific surface area.

Burning phenomena and the phases of the burning process fundamentally depend on the physical and chemical properties of the material involved. On its own, the energy content of sparks is insufficient for the ignition of the materials in the environment or to initiate an explosion. The combustible materials at the place of lightning stroke and its surroundings might ignite and burn off.

It is interesting to note that the ignition temperature as determined by various test methods differs. The buildings for handling and storing radioactive materials as well as for their technological use need to be built of non-combustible materials of high fire resistance.

These parameters are combustibility, ignitability, ability to develop smoke, inclination to produce toxic gases and burning dripping. Experience has shown that all the ignition sources, even of minimum ignition energy, are capable of igniting dust clouds open flames, electric arc, mechanical or electrostatic spark, hot surfaces, etc.

Fires of metals may be controlled with very early detection, the rapid and appropriate action of fire-fighters using the most effective method and, if possible, removal of metals and any other combustible materials from the zone of burning or at least a reduction of their quantities.

Fire Hazards

They can have a very strong ionizing effect, and are capable of the fatal destruction of living organisms. The structure and shape of these macromolecular materials, produced by polymerizational, polyadditional or polycondensational reactions, will strongly influence their properties.

Experience has shown that fire and explosion might occur-depending on the temperature and pressure of the system-within the range of concentration between the two flammable limits. Depending upon whether or not this parameter is determined-with special test methods-by the use of any ignition source, we distinguish between the piloted ignition temperature and the auto ignition temperature.

Dust can be an explosion hazard not only when floating in the air, but also when settled.

Burners, matches, furnaces, heating equipment, flames of welding torches, broken gas and oil pipes, etc. With the knowledge of these parameters, one can allocate the fields of their application determined, pointed out, setand the fire safety provisions can be elaborated.

Some metals have such a high sensitivity that they are stored separately from air, in inert gas atmospheres or under a liquid that is neutral for the metals.

The non-combustible gases not supporting burning are called inert gases nitrogen, noble gases, carbon dioxide, etc. The working safety of electrical systems is most frequently endangered by short circuits.

The test results obtained influence the fields of application for these products tents and flats, furniture, vehicle upholstery, clothes, carpets, curtains, special protective clothing against heat and weatheras well as the stipulations to restrict the risks in their use.

Clothing, furniture and the built environment partly or totally consists of textiles. The effect will be the same if inert gases are mixed in the mixture of air and dust, because the oxygen concentration necessary for burning will be lower.

Fire Hazards

The choice of the proper extinguishing agent and the process in which it is applied are of great importance. In these cases, safety is provided by tools that do not spark, i. A large number of tools in general use and various types of technological equipment operate with open flames, or enable the formation of open flames.

The choice of the proper extinguishing agent and the process in which it is applied are of great importance. Information on the properties of chemicals can be obtained from the technical data sheets issued by manufacturers and from the manuals and handbooks containing the data of hazardous chemicals.

In cases of short circuits, when some units of the electric system come in contact with each other, the resistance will be considerably lower, and as a consequence, the intensity of current will be extremely high, perhaps by several orders of magnitude higher.

The toxicity of chemicals, as potential fire hazard, may act in two ways. This is the reason for which the data published in literature for autoignition temperature and piloted ignition temperature can be significantly different.

A large portion of the current flowing through places with increased resistance will transform to heat energy. If this energy cannot be dissipated sufficiently and the reason cannot be eliminatedthe extremely large increase of temperature might lead to a fire condition that endangers the surrounding.

Chemicals Knowledge of the hazardous parameters of chemicals is one of the basic conditions of safe working. For these materials, the requirements for the conditions of storage and the rules for storing in the same place together with other materials should be carefully considered.

Essay Health and Safety - The Bradford City Fire. Gemma Kelly Health and Safety - The Bradford City Football Fire M3 – The health, safety and security issues that occurred within the Bradford fire were that the stands were wooden and smoking was allowed.

The different types of safety consist of being on the apparatus, safety in the fire station, personal safety, tool and equipment safety, safety in training, and emergency scene safety.

Riding the apparatus is the most common danger to a firefighter. Fire safety becomes everyone's job at a worksite. Employers should train workers about fire hazards in the workplace and about what to do in a fire emergency.

This plan should outline the assignments of key personnel in the event of a fire and provide an evacuation plan for workers on the site.

In. Fire Hazards of Materials and Products The presence of combustible material in combustible systems represents an obvious condition of burning.

Burning phenomena and the phases of the burning process fundamentally depend on the physical and chemical properties of the material involved.
