Risk areas

One test, made at the Radcliffe Infirmary in Oxford, " identified two areas of the UK in which the incidence of stomach cancer was particularly high and two in which it was particularly low. People attending hospitals in these areas as visitors rather than patients were asked to provide samples of saliva. The hypothesis suggested that samples from the high-risk areas should contain more nitrite and nitrate than those from the low-risk areas, but this was not so. The samples from the low-risk populations had nitrate concentrations 50% greater than those from the high-risk areas. 

Place a red triangle warning device at the rear of the vehicle and near any spillage Prevent smoking and direct other vehicles away from any fire risk area Upon the police/fire brigade taking charge ... 

Fire Risk Area - A process plant is subdivided into fire risk areas, each of which is the maximum area which can reasonably be expected to be totally involved in a single fire. This is used to determine the combined requirement for... 

In order to determine the total vapor capacity to be relieved when several vessels are exposed to a single fire, a processing area is considered as being divided into a number of single fire risk areas. Plant layout should be designed... 

When a fire occurs, it is assumed that all fluid flow to and from the fire risk area has been stopped. Therefore, flow loads such as control valve failure or incoming feed streams are not additive to the fire load. Credit is not generally given to flow out through normal channels, since they could also be blocked during the fire emergency. 

If a situation occurs which involves more than one fire risk area simultaneously (such as an entire Refinery or Chemical complex), it would be classed as a remote contingency event, and the 1.5 Time Design Pressure Rule may be applied. 

Class I-III Cabinets Containment cabinets used for various requirements. In a high-risk area, a Class III cabinet would be used. Class I and II cabinets are used in low-risk areas. 

These are Just some examples of key areas this is not an exhaustive list. Look around your workplace to identify other risk areas. If any risks apply to your work activities, you will need to do risk assessments to check that you have removed or reduced the risk. 

Are raw process and waste materials stored in a safe and appropriate manner for example, are bulk acids in tanks bunded with secondary containment, are flammable materials in a fire-protected, ventilated store, are powders and pellets in areas fitted with dust extraction segregation of noncompatible materials Provide details of existing storage arrangements, inducing plans and specifications. Identify risk areas. Identify the risk category. 

Has consideration been given to the requirements for segregation of incompatible materials Provide details on the type of wastes stored in specific areas. Identify risk areas. Identify the risk category.

Identification of high risk areas through a program to assist States in conducting surveys to identify these areas, and through the development of predictive geological models. 

EPA is approaching this problem in two ways (1) by encouraging and providing assistance for State surveys to identify high risk areas and (2) through the development of predictive methodology to identify such areas. 

The flammability properties of the hydrophilic PU foam developed in USA in the late 1970 s were outstanding even under severe fire conditions but it s physical properties and high densities restricted its use for other than highly specialised high risk areas.
