Danger zones

Provision of an adequately equipped emergency control centre of suitable design located outside potential danger zones. 

Red means stop This is a danger zone. Notify the primary care health provider immediately. Use the medication prescribed when peak flow readings indicate that asthma is not in good control. 

By producing transparent versions of the maps and superimposing copies related to different classes of risk it is possible to synthesise a msip that helps identify danger zones - areas of high risk density. 

For display shells of 200 mm and above, reinforced fibreglass mortar tubes are invariably used. Welded steel tubes have long been considered to be amongst the safest because, in the event of a pressure-burst, the tube will split in the vicinity of the weld, thus creating a predictable danger zone. With seamless tubes the fragmentation is completely random and creates a shrapnel hazard for the fireworks operator. 

The safe use of AcaO—HClO as electrolytic polishing bath has been investigated by Hikita Asaba (Ref 12) and by Me dard Sartorius (Ref 10) resulting in a 3 phase diagram to show the dangerous zones... 

Generally, a distance of approximately 200 km of the Trans Caucasian main gas pipeline is considered a dangerous zone in terms of geodynamic events. Currently the complex geodynamic conditions are observed at the river Amala, Baidar and the Kuro area (in the Kazbegi region), where intense erosion and mudflow occurrences are present. 

Dinitrobenzene is sparingly soluble in water. It is prepared by direct nitration of benzene or nitrobenzene. It is an insensitive explosive. For purposes of official transport regulations, the sensitivity and the reactivity of dinitrobenzene are just on the limit between high-explosive and the non-dangerous zone. 

This involves the clarification of the danger zone in the factory, fire extinguishing equipment, the number of workrooms, the maximum number of workers in a room, the limit on the maximum quantity of explosives allowed in a room, special or exclusive use of a room, equipment, instruments, e.g. for red phosphorus use, for chlorate use etc. 

The dangerous zone is divided into two parts upper (1) in which pyrolysis mainly occurs and is manifested by rapid variations of pressure and explosions, and lower (2) where the reaction proceeds quietly, but the products are liable to react further. He also indicated a practical criterion of the reaction the colour of the products. Yellow colour characterized the normal course of the reaction,... 

As soon as this Dream-I sinks to the lowest threshold of perception, it enters into a danger zone, where the personal and collective subconsciousness flow together, and out of the latter, dark chaotic figures emerge (encounter with the Guardian of the Threshold). 

Bleaching with hypochlorite solution containing 1 g/1 of available chlorine with the addition of 5 g/1 sodium carbonate at pH close to 7 can be done in just 10 min. The system is more reactive in the danger zone and thus bleaching can be done in a shorter time. 

Once a suitable power source has been determined, it s time to move onto cap assembly. First one puts the igniter wire into the cap. It should be positioned along the wall of the cap body so there is room to add other ingredients to the cap. Next add enough reloading powder to fill the cap about one-quarter full. The relatively safe part of the job is now done. From here on out, it s into the danger zone ... 

Although the concentration of vapor must be kept well below the danger zone, it should not be reduced to a needlessly low point as this involves handling unnecessarily large volumes of air. The vapor concentration is maintained at the optimum point by proper design of the hoods at which the vapor-laden air is collected. Devices are available which automatically maintain the vapor concentration at the proper point.
