Protective capabilities

Protection capabilities of bags can be maximized by maintaining the moisture content of the paper at 6—8% by weight, relative to a shipping environment of 21°C at 60% in relative humidity. When the moisture content of shipping-sack paper drops below 6%, the sacks become excessively brittle however, if short-term storage under such conditions is unavoidable, an attempt should be made to place them in an environment with adequate relative humidity for 24—48 hours prior to their use. 

Process units and facilities now have a potential operating life of many years. During the course of operation, it can be expected that changes will be made that effect fire protection capabilities. These changes could result in increased hazards, resulting in changes to ... 

Applications can be found in any sector where high durability and protection capability are required.

The combination of explosion safety technologies can provide more effective safety than is possible by deploying just one safety measure. In this respect, the improved capabilities of explosion suppression further enhance overall explosion protection capability. 

System approach interface engineering (SAIE) by means of low-pressure plasma in corrosion protection of metals was first applied on cold-rolled steel (CRS) [1-3]. Unlike aluminum alloys described in the previous chapters, oxides on the surface of steel and iron are less stable than those on aluminum alloys, i.e., iron oxides formed on the surface do not have corrosion protecting capability of iron underneath and hence are more vulnerable for corrosion. On the other hand, the oxides on the surface of steel can be removed by plasma treatment, particularly of (Ar- -H2) plasma. Hence, SAIE could be performed in totally dry processes. The improvement of corrosion protection by means of environmentally benign process was the motivation for the approach. 

Advice to naval leadership on the chemical warfare (CW) and biological warfare (BW) threat can be traced to the Cold War period. As the Navy undertook a major force buildup in the early 1980s, a memorandum from committee member Joshua Lederberg to the CNO, Admiral James Watkins, USN, was instrumental in precipitating the decision to equip some new vessels with collective protection capabilities and improved chemical weapons detectors.1... 

Corrosion tests in artificial atmospheres [1, 2, 3] are used as comparative tests for the evaluation of corrosivity of metals and metal alloys and corrosion protection capability of various corrosion protection means by metal plating, varnishing and paint coating as well as anodic and conversion coating. Therefore, it is essential to know precisely the corrosivity of the test cabinet environment. 

SPMs can now be found in commercial markets and specialty clothing due to their lightweight structure, liquid and aerosol repellent properties, and facilitation of moisture vapor transport. However, for military use, SPMs have limitations (Wilusz 2007). SPMs may act as liquid-repellents but may allow vapors to pass and therefore need an activated carbon layer to add extra protection capabilities. Moreover, military garments experience tremendous stress on a day-to-day basis. SPM-based ensembles are more susceptible to tearing as compared to activated carbon-based textile fabrics (Wilusz 2007). Optimizing the permselectivity of the membrane by surface modification or other such techniques is necessary to achieve a balance between comfort (e.g., moisture vapor transmission) and chemical vapor barrier properties. Furthermore, SPMs or membrane-carbon ensembles must possess acceptable mechanical strength to sustain daily military operations. 

Initially this increased risk of myocardial infarction was attributed to the myocardial protective properties of the nonselective COX inhibitors. COX-2 selective inhibitors may lack this protective capability. Later meta analysis suggested that the degree of myoprotection associated with naproxen could not account for the difference in the incidence of myocardial infarction. Merck, the maker of rofecoxib, withdrew the drug from the market because of this association. The other two coxibs, celecoxib and lumiracoxib, remain on the market as no similar increase in myocardial infarction has been associated with these drugs. It must be stated here that there is controversy regarding this issue and only time will provide the ultimate answer regarding the car-diotoxic potential of these two coxibs. 

IDENTIFICATION OF PROTECTION. Protection reduces the probability of the consequence occurring given that the cause has occurred. There are two key questions to ask when reviewing the protection portion of a PrHA. First, is the protection capable of preventing the consequence if it functions correctly Second, will the protection function, given the cause For example, a normally open electric solenoid valve will not close after loss of electrical power and, therefore, cannot function as protection under that circumstance. A motor-operated valve also will not operate after loss of electrical power. However, a normally closed electric solenoid valve will automatically close upon loss of power.
