The second test apparatus mentioned is used to determine the maximum explosion pressure and the maximum pressure rate. It is a spherical stainless steel autoclave of 20 liters volume. Dust samples of up to 40 g per trial, covering a concentration range of up to 2 kg/m, are blown into the sphere through special ring nozzles. The dispersed dust is ignited with varying delay time. The pressxue/time-history is measured. The maximum pressure rate observed is transferred into the safety number Kst value with the help of the so-called cubic-root-law. 

With respect to all further considerations and the actual design, as well as the attribution of safety numbers to types of dryers and mixes, it is referred again to the literature mentioned.

At point A, despite full management commitment to safety performance, with low employee commitment to safety, the number of accidents remains high employees only follow procedures laid out because they feel they have to. At the other extreme, point B, when employee commitment is high, the number of accidents reduces dramatically employees feel responsible for their own safety as well as that of their colleagues. Employee commitment to safety is an attitude of mind rather than a taught discipline, and can be enhanced by training and (less effectively) incentive schemes. 

The safety triangle shows that there are many orders of magnitude more unsafe acts than LTIs and fatalities. A combination of unsafe acts often results in a fatality. Addressing safety in industry should begin with the base of the triangle trying to eliminate the unsafe acts. This is simple to do, in theory, since most of the unsafe acts arise from carelessness or failure to follow procedures. In practice, reducing the number of unsafe acts requires personal commitment and safety awareness. 

To give some structure to the process design it is common to present information and ideas in the form of process flow schemes (PFS). These can take a number of forms and be prepared in various levels of detail. Atypical approach is to divide the process into a hierarchy differentiating the main process from both utility and safety processes. 

Beside all these safety reasons, we are able to test 2 or 3 drums at the same time and by some improvements of the application we are able to reduce the test-period down to 4 hours, which results in an also for the production sufficient number of tested drums during the short shut down periods. These increase the availability and the production output of a plant and result therefore in a gain of safety an economical competitiveness of the European industry. 

The separation of cells from the culture media or fermentation broth is the first step in a bioproduct recovery sequence. Whereas centrifugation is common for recombinant bacterial cells (see Centrifugal separation), the final removal of CHO cells utilizes sterile-filtration techniques. Safety concerns with respect to contamination of the product with CHO cells were addressed by confirming the absence of cells in the product, and their relative noninfectivity with respect to immune competent rodents injected with a large number of CHO cells. 

Specifications, Standards, Quality Control, and Health and Safety Factors. Formerly, there was an Insulation Board Institute representing the insulation board industry, but the decline in the market and number of producers has led to its demise. Currently (ca 1997), the industry is represented by the American Hardboard Association (AHA). Specifications and standards are found in American National Standards Institute (ANSI) standard for CellulosicFiberboard (7). The standard includes descriptions of the various types and classes of ftberboard, as well as requirements for physical and dimensional stabiUty properties. QuaUty control tests are limited to a few basic strength and stabiUty tests, including bending strength, bond strength, and moisture resistance. 

Many compounds explode when triggered by a suitable stimulus however, most are either too sensitive or fail to meet cost and production-scale standards, requirements for safety in transportation, and storage stability. Propellants and explosives in large-scale use are based mosdy on a relatively small number of well-proven iagredients. Propellants and explosives for military systems are manufactured ia the United States primarily ia government owned plants where they are also loaded iato munitions. Composite propellants for large rockets are produced mainly by private iadustry, as are small arms propellants for sporting weapons. 

The assessment of the contribution of a product to the fire severity and the resulting hazard to people and property combines appropriate product flammabihty data, descriptions of the building and occupants, and computer software that includes the dynamics and chemistry of fires. This type of assessment offers benefits not available from stand-alone test methods quantitative appraisal of the incremental impact on fire safety of changes in a product appraisal of the use of a given material in a number of products and appraisal of the differing impacts of a product in different buildings and occupancies. One method, HAZARD I (11), has been used to determine that several commonly used fire-retardant—polymer systems reduced the overall fire hazard compared to similar nonfire retarded formulations (12).
