Exit Routes

Fig. 1. Exit route of xenon in simulations of the extraction process. The xenon atom is solid black. The atoms of the residues surrounding the exit path are shown a.s spheres, and the protein backbone is shown as a thin curve. On the left, the xenon is viewed through the exit between residues on the right, the view is from (ho side and the direction of the tug is marked with a line.

Exit routes and doors from all facilities should be provided according to the requirements of NFPA 101. The minimum width of all exit routes should not be less than a standardized width, 1.0 meter (39 inches) being commonly adopted. Where low occupancy rooms are provided in offshore facilities near process areas, a secondary emergency escape hatch is provided as an alternative means of escape in addition to the normal means of egress. 

Incidental combustible liquid storage (e g., lube oil reservoirs, fuel day tanks, etc.) should normally not be installed within 1.8 meters (6 ft.) of an emergency exit route, especially if it is the only means of egress from an enclosure. 

Wet or dry chemical fixed suppression systems are typically provided over the kitchen cooking appliances and in exhaust plenums and ducts. Activation means is afforded by fusible links located in the exhaust ducts/plenums usually rated at 232°C (450°F). Manual activation means should not be provided near the cooking area, but in the exit routes from the facility. The facility fire alarm should sound upon activation of the fixed suppression system and power or gas to the cooking appliances should be automatically shut off. The ventilation system should also be shut down by the activation of the fire alarm system. Protective caps should be provided on the suppression nozzles to prevent plugging from grease or cooking particulates. 

Figure 3.2. Generalized clean room design. Entry of personnel occurs via changing rooms, where the operators first remove their outer garments and subsequently put on suitable clean room clothing (see e.g. Figure 3.3). All raw materials, portable equipment, etc. enters the clean room via a transfer lock. After being placed in the transfer lock, such items are sanitized (where possible) by, for example, being rubbed down with a disinfectant solution. They are then transferred into the clean room proper, by clean room personnel. Processed product usually exits the clean room via an exit transfer lock and personnel often exit the room via a changing room separate from the one they entered (in some cases, the same changing room is used as an entry and exit route). Note that, in practice, product may be processed in a number of different (adjacent) clean rooms...

Emergency planning includes tornado and storm shelters, flood protection, earthquakes, proximity to public areas, and safe exit routes. It also includes planning for the effect that an emergency in the new process would have on other plants, and the effect that an emergency in another plant would have on the new process. The effects of potential spills on waterways and aquifers should be considered. 

Air locks and pass-throughs are bidirectional and can be used for movement in either direction. When used as an exit route, the decontamination procedure can be omitted. Where production volumes warrant separate entry and exit, air locks may be necessary to maintain both adequate capacity and separation between clean and used items. In an emergency, airlocks can serve as emergency exits for personnel, in which case the interlocks can be overridden. 

The recent rise in LBO activities has also created a httle known phenomenon the largest number of deals that have yet to exit Our research indicates that only one third of LBO deals closed over the last twenty years have exited, most sold to trade buyers, with IPOs becoming an unhkely exit route (Fig. 8.9). There are indications from our interviews that some LBO owners are now becoming impatient with the increasing difficulty of achieving the kind of exit they had once hoped for. There is an increasing sense that the real test for the more recent LBO players in chemicals will come when they seek their exits. Some industry observers indicate there is now reason for caution about the rate at which the chemical LBO market will continue to grow. 

Make sure that you know what to do in case of fire, including exit routes, how to raise the alarm, and where to gather on leaving the building. Remember that the most important consideration is human safety do not attempt to fight a fire unless it is safe to do so. 

Be familiar with the emergency exit route (Figure 1.5). In the event of a fire alarm, proceed in an orderly fashion to the nearest exit. 

Looking up slope-shaft E at Spring Quarry. This was the emergency exit route from the main operatives canteen area in the south-east section of the quarry. 

Emergency Evacuation Training Preparing for the Future First responder, pre-planning, notification systems, exit routes, assembly areas, all-clear signals, and lines of authority. 

A similar behaviour is shown by the axon of the grasshopper motoneuron FETi (Fast Extensor Tibiae), which consistently extends down aberrant pathways in the body wall when its normal exit route from the CNS, nerve 5, is missing (Whitington and Seifert, 1984). However, the growth of the FETi axon in the periphery in this... 

These engineers do not normally contribute any power consumption data, but their input to the work of the electrical engineer is to advise on subjects such as equipment layout, access to equipment, maintainability, maintenance lay-down space, emergency exit routing, operational philosophies of plant and systems, hazardous area classification. 

Procedures for emergency evacuation, including type of evacuation and exit route assignments ... 

Occupants must be able to open an exit route door from the inside at all times without keys, tools, or special knowledge of door operation. Exit route doors... 

Exit routes must support the maximum permitted occupant load of each floor and the capacity (width) of an exit must not decrease in the direction of travel. 

Exit routes must be arranged so that occupants will not have to travel toward a high-hazard area (such as a flammable liquid storage room), unless the path of travel is effectively shielded from the high-hazard area by physical barriers.
