Fire precautions flames

SAFETY PRECAUTIONS - Very stable, but should be made up as needed. AN should be kept dry to ensure proper detonation. This explosive is a definite fire hazard. Flame and heat should be avoided. Not shock sensitive as explosives go, but can be detonated by a very sharp blow (30cm drop of a 2 Kg. weight will detonate). Copper and brass should be avoided in manufacture and all munitions loading and finished products. 

Polymers possess the benefit of low density, and in the form of composites they can obtain a very high strength/weight ratio. They are therefore suitable in means of transport. The application of plastics on offshore platforms has been limited primarily because the demands on fire precautions are stricter than they are onshore, and for some purposes due to higher cost than the metallic alternatives. The use of polymers offshore has, however, increased in recent years. One field of application where these materials are interesting is pipe systems of flame-resistant polymers. 

Health nd Safety Factors. The mononitrochlorobenzenes are toxic substances which may be absorbed through the skin and lungs giving rise to methemoglobin. Their toxicity is about the same as or greater than that of nitrobenzene. The para isomer is less toxic than the ortho isomer, and the maximum allowable concentration that has been adopted for -nitrochlorobenzene is 1 mg/m (0.1 ppm) (6). The mononitrochlorobenzenes are moderate fire hazards when exposed to heat or flame. They ate classified by the ICC as Class-B poisons. The same handling precautions should be used for these compounds as are used for nitrobenzene. 

The inflammable solvents most frequently used for reaction media, extraction or recrystallisation are diethyl ether, petroleum ether (b.p. 40-60° and higher ranges), carbon disulphide, acetone, methyl and ethyl alcohols, di-wo-propyl ether, benzene, and toluene. Special precautions must be taken in handling these (and other equivalent) solvents if the danger of fire is to be more or less completely eliminated. It is advisable to have, if possible, a spedal bench in the laboratory devoted entirely to the recovery or distillation of these solvents no flames are permitted on this bench. 

Various fires and explosions caused by use of wooden containers with chlorates, and precautions necessary during handling and storage, are discussed [1,2]. A wooden pallet burst into flames as it was dragged across ground contaminated with sodium chlorate [3],... 

A patented water injection system has been devised for extinguishing oil and gas well fires in case of a blowout. The "Blowout Suppression System" (BOSS) consist of finely atomized water injected to the fluid stream of a gas and oil mixture before it exits a release point. The added water lowers the flame temperature and flame velocities thereby reducing the flame stability. In the case where the flame cannot be completely dissipated, the fire intensity is noticeably deceased, preserving structural integrity and allowing manual intervention activities. A precaution in the use of such a device is that, if a gas release fire is suppressed but the flow is not immediately isolated, a gas cloud may develop and exploded that would be more destructive that the pre-existing fire condition. 

Coal Mine Fires. Fires in coal mines are particularly dangerous not only because a naked flame may ignite firedamp (or coal dust) and initiate an expln, but also because coal itself provides a virtually unexhaustible supply of fuel. Every precaution should be taken to prevent such fires and the use of combustible materials in mines should be avoided. As an example of fire caused by a combustible article, may be cited the disastrous fire in 1950 at Creswell Mine, England, responsible for the death of 80 people. It was caused by flammable rubber conveyer belting. To prevent a repetition of such disaster, the British National Coal Board ordered replacement of all underground rubber belting by non-flammable polyvinyl chloride belting... 

Burner management controls, complete with flame scanners, purging, and cooling should be provided to ensure boiler safety. Supplementary firing should be limited to a fraction of the gas turbine load. The applicable safety codes are a function of the presence of fuel gas in the proximity. Precautions include the use of double stuffing glands with bleeds between the glands on... 

Fire protection Keep away from ignition sources naked flames. Take precautions to avoid static discharges in working area. 

Many slush baths " are inflammable - the normal precautions should be taken to avoid fire or explosion, i.e. no flames should be permitted in the vicinity of these inflammable slush baths. 

Observe normal precautions appropriate to the circumstances and quantity of material handled. Chlorocresol can be irritant to the skin, eyes, and mucous membranes. Eye protection, gloves, and protective clothing are recommended. Chlorocresol presents a slight fire hazard when exposed to heat or flame. It burns to produce highly toxic fumes containing phosgene and hydrogen chloride.
