Foam use in regular fire-fighting, particularly in industrial situations, has been common for a number of years now. However, foam is a relative newcomer as a tool in combating forest and grassland fires. Wetting agents have been a standard in the field, used to "stretch" the available water supplies in situations where water is often at a premium. 

Tanks should be grouped so that no more than two rows of tanks are provided within diked areas separated by roads to ensure fire fighting access is available. Large tanks within a common diked area should be provided with intermediate spill dikes or drainage channels between the tanks, as an intermediate level of protection against spill spread. When a small number of small tanks are located together the level of major impacts is less and therefor the financial risk is lower. In these cases it is acceptable not to provide full or intermediate dikes. 

GMT can be preferred to SMC for small or medium runs in the automotive industry. For example, German fire-fighting equipment manufacturer Rosenbauer is using ther-moformed sheet (multilayer ABS/PMMA) instead of hand-laid GRP. The cost of a body panel can be cut by 30% if the number of parts - in Three-digit quantities - is sufficient to justify the investment in thermoforming tools. 

One thing should always be remembered. Under direct attack of the most severe fire, paint and many other forms of fighting fire have limited value. At the edges of the fire, however, the combustion may be equivalent to a finite number of matches. The combustion of a finite number of matches is controllable. Properly designed paints will, in any case reduce the rate of fire spread. The reduction may make it possible for additional fire-fighting techniques to take effect quicker as well as having a fire of smaller magnitude to combat. 

Not only should laboratory workers be aware of emergency telephone numbers, but they also should know the location and proper use of fire-fighting appliances, rescue equipment, and emergency exits. They also should be familiar with the prescribed procedure for evacuating the building and the location of the outside assembly point where personnel rollcalls will be checked.

When a leakage happens, the chain of information has to be indicated, with telephone numbers, in order to call for help without loss of time. In most cases the upper management of an operation has to be informed as well, so that reference to the alarm plan would be useful. With chemical reactions - if not already described within the standard operation procedure - indication of safety measures are appropriate in case of deviations of temperature or pressure. In case of a fire, the instruction should contain information on suitable fire extinguishing agents, especially when water is not allowed for use. Further information on that subject can be found in Chapters 5 (fire fighting measures) and 6 (accidental release measures) of the material safety data sheets. 

Each code consists of a number, indicating the fire-fighting medium that should be used, and a letter which covers the explosion risk, the protective clothing to be worn and the action to be taken. In some cases a second letter, always E , indicates that evacuation of people may be necessary and should be considered. 

In the event of having to fight a fire of more than one solvent, the fire-fighting medium designated by the highest number should be used. Note, alcohol-resistant foam should normally be stored on a premises storing chemicals and, if more than one site in the near neighbourhood may need to use it, the ... 

Collection of samples for organic component analysis has a number of special difficulties. The sampling platform (i.e., the ship) is a considerable source of organic material, notably hydrocarbons from fuel and lubricating oil residues and CFCs/halons from refrigeration and fire-fighting equipment. Considerable attention must therefore be paid to sample design such that the sampler can be deployed, retrieved, and the sample processed without exposure to external contaminants.

The number and type of fire extinguishers required is dependent on the level of fire risk and the size of the premises. Fire fighting capacity is indicated by either an A rating for carbonaceous material fires or a B rating for liquid fuel fires. The actual rating is determined by tests specified in BS 5423 1987. 

Freons (Sect. 11.8) CFCs that were heavily used for a wide variety of commercial applications, including as refrigerants, as propellants, in the production of foam insulation, as fire-fighting materials, and many other useful applications, frequency (Sect. 15.1) For electromagnetic radiation, the number of wavelengths that pass a particular point in space per unit time.

The fire safety facilities provided should include a number of fire warning devices and fire-fighting appliances suitably placed aroxmd the site. All those on site should be trained in what to do in the event of a fire and the evacuation procedure. This can be linked to emergency evacuation. 

A number of metals and metal powders found in industrial situations and in transport will burn. Some metals burn when heated to high temperatures by friction or exposure to external heat. Others burn from contact with moisture or in reaction with other materials. These metals and metal powders require special extinguishing agents and special fire-fighting techniques. Some result in explosions and very high temperatures, and some react violently with water. Still others give off toxic fumes when burning. 

In addition, other laws, including the Fire Act, stipulate what should be taken into consideration in designing as to the performance of fire detectors and the water sources of fire fighting water supply systems. Redundancy and diversity of the fire fighting pump system and compliance to the law on the location and numbers are confirmed in the course of PSR, as well.

The site of the fire will present a number of significant and unusual hazards. The normal substances in the workplace may have undergone a chemical reaction and be more hazardous than before the fire. In addition to the normal products of combustion, including soot, contaminated water used for fire fighting may contain carcinogenic material. Other hazards may be presented by the building materials which will themselves have been affected by the fire. The elements of the building may have been seriously weakened or asbestos may have been disturbed.
