CONFINED SPACE A spacc which is substantially, although not always entirely, enclosed and where there is a reasonably foreseeable risk of serious injury from hazardous substances or conditions within the space or nearby. The risks may include flammable substances oxygen deficiency or enrichment toxic gases, fume or vapour ingress or presence of liquids free-flowing solids presence of excessive heat. For the purpose of the Confined Spaces Regulations 1997 a confined space means any place, including any chamber, tank, vat, silo, pit, trench, pipe, sewer, flue, well or other similar space in which, by virtue of its enclosed nature, there arises a reasonably foreseeable specified risk. 

Vessel or equipment cleaning can also be automated, e.g. using high-pressure liquid sprays. This is essential, whenever practicable, to avoid entry under the Confined Spaces Regulations 1997.

Fig. 11.—Schematic Diagram of the Interaction of a Guest with Gamma Cyclodextrin Bearing Two Naphthyl Groups. [Ueno and coworkers proposed two possible mechanisms of inclusion, I and 2. In 1, one of the naphthyl groups acts as a space regulator. In 2, the two naphthyl groups form a flexible, hydrophobic cap across the cavity of the cyclodextrin. In the cases of the guests that they investigated, Ueno considered that mechanism 2 is predominant.]...

All design methods to be discussed in this section are for linear dynamic systems. Such systems can be described in the time domain by the state space regulation equation... 

An interesting situation is the enhancement of fluorescence of a-napthoxyacetic acid in y-cyclodextrin by the space regulating role of cyclohexanol. Excimer formation also occurs in these systems. 

The level of proliferation attained by SMC as part of the wall response to endothelial injury has already been described by Schwartz and coworkers [7] as an appearance of consecutive, time- and space-regulated waves . Each wave is characterized by a precise set of growth factors/hor-mones/cytokines whose activity imposes a specific pattern of proliferation and/or migration on SMC. Based on a comparative analysis performed on developing and endothelial damaged wall arteries, Belknap et al. [27] came...

Because of this lack of detail, many construction companies use the general industry confined space regulations at 1910.146. The general industry regulations are used in this talk. 

In this case, we called Y a spacer or a space-regulating molecule which narrows the large y-CD cavity. The charge-transfer complex formation enhanced by y-CD is another evidence of the Type B complex formation. ...

Risk assessment is an essential requirement of the Confined Spaces Regulations and must be done so that a safe system of work may be determined. The risk assessment needs to identify the hazards present in the confined space, assess the risks and determine suitable controls to address those risks. The first part of the risk assessment will determine whether the work can only be done in the confined space.

A vessel large enough for entry will almost certainly come under OSHA s definition of a "confined space." Regulations and permits for such work are covered in Sections 4.5.1 and 7.1.4.
