Danger point

Occasionally all the valves on a ring main would be closed and the pressure in a pump rise to danger point. No one appeared to realize that there was anything wrong with this state of affairs. 

Focusing on the CH catastrophe we notice from Eq. (26) that the most dangerous point is where Xa is largest. In the MC models considered this obviously corresponds to a = 0 increasing a orients dipoles and makes them less susceptible to variation of the... 

Operators will often watch the readings from an array of thermocouples in a reactor, as an indication of imminent hot spot formation. The historical danger point for the reactors of Table I has been a band of 35°F. It is interesting to note that the average positive temperature fluctuation within a disturbance, from the integral of Equation (21), is about 30°F. 

Industrial plants may have their own medical staff, or a physician can be called and ambulances may be available in the nearby hospital for rapid transportation. First-aid measures can be taken until the arrival of qualified staff. In addition, medical assistance and firefighters may be requested as soon as possible, while the injured person should be given first aid and moved from the dangerous point. Normally it is not advisable to move any injured person if there is no nearby life-threatening hazard. This is to avoid aggravating any injury. If it is desirable to move a person, care should be taken that there should be no stress or strain imposed on the injured part of the body. 

Danger points 1, 2 and 3 (see above) can be related to a quotation from Paulus of Aegina (625-690 AD) At all events, avoid any rapid evacuation of the fluid, since there are some ignorant operators who have removed the life and soul of the patient with the fluid, thereby bringing the life of the patient to an end. ... 

The front hall and the staircase arc the two most dangerous points. Try medxod of getting and do rom floor to floor but the main staircase. If it u not barricaded it will certainly be mined. The fire escape may help. If the staircase must be used, fcjpl in front of you with a kmg pole or throw a grenade at it, to set off any boot traps. 

Second, try to keep the person in question awake, at least for the next couple of hours, until you re sure the danger point has passed. The longer he is awake, the more chance the system has of getting all the drug through the bloodstream. Check every now and then to make sure breathing is normal. 

There are practical difficulties in working with vapor concentrations in the upper nonexplosive zone, because there is always a possibility that the concentration may be diluted to a dangerous point through leakage of air. In the relatively few cases where it is necessary to use high vapor concentrations, it becomes desirable to employ a noninflammable solvent, or else, provide an inert atmosphere. The latter involves installation of completely enclosed equipment to prevent access of air. 

Bar Koehbar always fought in the front line at the most dangerous points. He led two hundred thousand men to establish an independent Jewish state, but it was to last only three years. The Romans lost an entire legion regaining eontrol. In retribution, the Romans leveled one thousand villages, killed half a million people and sent many thousands of people abroad as slaves. 

VALVE, PRESSURE RELIEF - A valve designed to minimize the possibility of explosion when air temperature surrounding a refrigeration system may rise to a point where the pressure of the refrigerant gas to increase to a danger point. 

By inspection of a layout of the shield structure, a danger point is. selected and a line along the path of minimum attenuation determined. This line is generally inadirection from the outer to the inner mouth of the duct. The intensity contribution of the surface element at the source/of the minimum, path is calculated, as well as the contribution of all neighboring surface elements which can be "seen through the effectively thinner j>ortion of the shield. These neighboring contributions usually fall off very rapidly as elements further from the minimum line are considered. 

A second danger point for electrochemical corrosion is at the junction of the aluminium and the steel which must comprise the water cooling system outside of the pile. Tests on inhibitors and corrosion from H2O2, O2, H2, etc. in hot water while under radiation seem to indicate no great danger from corrosion at these junctions, if proper precautions are taken. 

Figure 13-3. The distance guards must be located from a danger point depends on the size of the opening in the guard.

Mechanical power transmission equipment that is out of reach of people may not require guards. Various standards set the minimum distance required from a floor or walking surface to overhead mechanical power transmission apparatus. The minimum distance is often about 8 ft. Most people would not be likely to contact or reach above this distance. Anthropometric reach data can also establish safe distances from people to danger points. Distances to danger points within reach require guarding. There may be overhead or enclosing screens, walls or fences that create safe locations. These barriers must be permanent and substantial. Only trained workers should have access to the enclosed locations. 

The sensing device must be far enough from the danger point to assure that someone cannot reach into the point-of-operation faster than the time needed to stop the machine. 

A proposed British Standard provides more usable, and appropriate, data for both reach-through openings and reach-over barriers. Two sets of reach-over data are proposed. The first is based on the existing standard and would only be suitable for low-risk situations where people are unlikely to attempt to reach the danger point. The second is aimed at preventing determined attempts at reaching dangers that have the potential to cause serious injury. The recommended reach distances are comparable with, but rather more cautious than, the data presented in Table 26.4. 

A viable decision shall be made, with a minimum of delay, that the danger point has been reached. 

A trip device does not physically keep people away but detects when a person approaches close to a danger point. It should be designed to stop the machine before injury occurs. A trip device depends on the ability of the machine to stop quickly and in some cases a brake may need to be fitted. Trip devices can be ... 

ALL OTHER APPARATUS IS DANGEROUS Points at which system is isolated. . 

One caveat that 1 need to emphasize is that not all competition is good competition. There can be serious consequences for applying it ignorantly. This article will take you through the process of creating productive competition and tell you how to sidestep the danger points that you may face along the way. 

And here s the third danger point Adrenaline and cortisol also activate another part of the brain called the hippocampus. The hippocampus is involved in two parts of memory. For about an hour, it helps to store new information. But after an hour, it switches to organizing and attaching the information to existing cognitive mental models so that it can be remembered later at the right time in the right place. So the competition should last no more than an hour.
