Extract of sample "Flammable and Combustibles"

Flammables & combustibles Flammable and combustible liquids are liquids that can burn. They are ified, or grouped, as either flammable or combustible by their flashpoints. Generally speaking, flammable liquids will ignite (catch on fire) and burn easily at normal working temperatures. Combustible liquids have the ability to burn at temperatures that are usually above working temperatures.
What is a Flash Point?
The flashpoint of a liquid is the lowest temperature at which the liquid gives off enough vapour to be ignited (start burning) at the surface of the liquid. Sometimes more than one flashpoint is reported for a chemical.

Containers for flammable and combustible liquids shall be of the type, not exceeding the maximum capacities as set forth in the OSHA Standards.  Size limitation for containers must be followed in order to prevent ignition of liquid by sparks from static discharge during pouring operations. Refer to Table I for container size specification.
Program Components
Plan for Safety!
A good plan for safe use of flammables and combustibles contains the following components:
Control of ignition sources
Proper storage
Fire control
Safe handling
Open flames
Static electricity
Cutting and welding
Hot surfaces
Electrical and mechanical sparks
1. Electrical equipment and wiring should be suitable for the hazard.
2. If a heating operation is necessary, use only indirect heating methods.
3. Do not allow any open flames, hot surfaces, radiant heat sources or friction- and spark-producing equipment in flammable liquid areas.
4. Provide grounding and bonding for all equipment handling using these liquids.
5. Establish a maintenance program to assure that all equipment and safety controls are functioning satisfactorily.
Always provide adequate ventilation to reduce the potential for ignition of flammable vapors.
Accidental discharge is one of the major hazards concerning the storage of flammables and combustibles.
should be stored in tanks, drums, cabinets, or small containers

Drums and containers should be segregated from the rest to lessen potential fire risk.
Outside storage or storage in a detached building is preferred.
If the combustibles and flammables are stored inside, they should be stored in a detached room.
Suitable fire control devices, such as small hose or portable fire extinguishers must be available where flammable or combustible liquids are stored
Carefully read the manufacturer’s label.
Practice good housekeeping.
Clean up spills immediately.
Only use approved metal safety containers.
Keep the containers closed when not in use and store away from exits or passageways. 0slides%203-06.ppt Read More

The Security Professional and their role in Emergency, Disaster and Contingency Planning

...). In planning for a fire contingency one should be able to distinguish the different classes of fire and have the necessary equipment to handle any kind of fire. Different classes of fire have different causes. They include Class A which is caused by ordinary combustibles like paper, wood and cloth, Class B caused by flammable liquids like grease and gasoline, Class C caused by electrical equipment, motors and switches, Class D combustible metals and lastly class K caused by cooking oils and gas (Fischer, 2008). When planning for a contingency brought about by fire, the organization should make sure that they have all the resources relevant to fight any class of fire. The security...

Fireworks pressure, V=volume and T is temperature. The force of explosion is a component of the gas pressure. It is exerted equally in all directions obeying Pascal’s principle. Therefore, P=F/A where the ‘A’ is the area of confined combustibles. The force is responsible for the launching of the fireworks, their dispersion velocity and sound (report). Heat is a consequence of combustion and exothermic reactions such as oxidation and thermite-like redox reactions with the firework. The total summation of the energies produced obeys the first law of thermodynamics by adhering to the basic principle of “conservation of energy” 3) Hypothesis Fireworks are manufactured by compounds that are toxic,...

Fire Protection Management

...material, cooling it to the point at which combustion is no longer self-sustaining. Fires involving flammable liquids, certain chemicals, and combustible metals often require special extinguishing agents and techniques. With some fuels the use of water may actually be dangerous. Foam extinguishers use an aqueous film forming foam (AFFF) agent that expels a layer of foam when it is discharged through a nozzle. It acts as a barrier to exclude oxygen from the fire. Foam extinguishers work well in fire fighting, proven not only on Class A fires which include those ordinary combustibles such as wood, cloth, and paper. But especially on fires involving...

Collection of Arson Evidence and Analysis of Flammable Residue

...Running Head: Arson Collection of Arson Evidence and Analysis of Flammable Residue Arson can be defined as the crime of setting structures and buildings on fire and the motive is seen as deliberate and malicious. Arson can be done in various forms and can be committed in towns, cities, rural areas and even wild land. It is important to note that arson is different from other causes of fire such as spontaneous combustion, lightning and wildfires in that arson is committed by a human being. The study that is involved in the evaluation of the causes and the motives of arson is referred to as fire investigation. It has been deemed that many motives for arson exist and they include the need to collect insurance compensation, criminal... ...

Arsonist motivations and methods

...) explained that this fire setter lacks a conscious motivation for his act only that he take some form of pleasure from it. There is no method employed in this case as the pyromaniac set homes and properties on fire impulsively and that there is no plan for the fire setting. “Rather than carry flammables or combustibles to use as fuels in setting fires, they simply ignite whatever combustibles are close by.” (Redsicker and O’Connor p. 24) Crime Concealment Another type of arson is those committed to conceal other crime committed previously by the fire setter. Burglaries as well as murder are often masked by fires. Also missing items or those that could be used as evidences are mostly...

...Inflammable The term ‘inflammable’ is of interest since it has confusion and at times controversy over its usage. From the Oxford English Dictionary, the term means ‘combustible’ or ‘easily set on fire’. This is the adjective form of this word. The noun form of this term is the substance, which easily catches fire or can be easily set on fire, referred to collectively as the ‘inflammables’ (Drabble 1). There are also other derivatives of this term such as inflammableness and inflammability. However, this term ‘inflammable’ needs further reading about because it shares the same meaning with the other term; ‘flammable’ which many people would, and, in fact, should understand to be the opposite of the...

Common Ways to Ensure Fire Safety rise and the fire will die out. As it has been established, fire does not exist without the presence of these three components. To fight with fire, effectively, we need to identify the fuel for that fire. The fuel can range from solids to liquids to gasses. To enhance such process of detecting what has caused the fire, three certain classifications of fire are found. Though the US version and the Australian/Asian versions also exist, let’s refer to the European version for better understanding. Class A: Ordinary combustibles Class B: Flammable liquids Class C: Flammable gases Class F/D: Electrical equipment Class D: Combustible metals Class F : Cooking oil or...
