Fire growth safety

The plant internal PSA can be used to identify critical equipment that could be damaged by fire. This form of screening was employed in the fire-risk portions of ZIP. At each location considered, the loss of all the equipment in the zone is postulated regardless of the size or position of the fire in the zone. If this does not show the occurrence of an initiating event (LOCA or transient) or if the safety functions are not damage to required for safe shutdown, the location is eliminated from consideration. If the location is found to be critical, it is considered furilier lot-detailed fire growth and fire suppression analyses. 

This report presents experimental and theoretical results from a study within the project "Fire Hazard - Fire Growth in Compartments in the Early Stage of Development (Prefiashover)". The project is carried out jointly by the department of Fire Safety Engineering at Lund University and the Division of Fire Technology at the Swedish National Testing Institute. An outline of the research program is...

Some people may be at significant risk because they work in areas where fire is more likely or where rapid fire growth can be anticipated. Where possible, the hazards creating the high level of risk should be reduced. Specific steps should be taken to ensure that people affected are made aware of the danger and the action they should take to ensure their safety and the safety of others. 

The rapid growth and expansion of the chemical industry has been accompanied by a spontaneous rise in human, material, and property losses because of fires, explosions, hazardous and toxic spills, equipment failures, other accidents, and business interruptions. Concern over the potential consequences of catastrophic accidents, particularly at chemical and petrochemical plants, has sparked interest at both the industrial and regulatory levels in obtaining a better understanding of the subject of this book Health, Safety, and Accident Management (HS AM). The writing of this book was undertaken, in part, as a result of this growing concern.

However, current CFD cannot provide good predictions of HRR evolution (i.e., hre growth) in real complex enclosures/scenarios. Fire modeling is not yet able to predict the HRR, and research efforts need to be tailored toward this issue. However, hre environments for hre safety design can still be calculated using CFD, if the HRR is an input data to the design process. This is because, current CFD tools provide good predictions of the effects of a hre (e.g., temperature held, smoke movements, etc.) once the HRR is provided.

The required hazardous material information is primarily being provided to the fire departments as printed material presently but this is rapidly changing. Generic databases containing thousands of Material Safety Data Sheets are now available on optical disks (CD-ROMs) which provide encyclopedic amounts of data. SmaU computers have also developed the capabihty of inexpensively placing information on these disks so that locaUy specific irrformation can be added. The rapid growth of the Internet and the expansion of high speed data access also makes it feasible to obtain MSDS... 

The greatest development in the rapid growth in plastics consumption for transport is in the motor vehicle industry, so it is little wonder, that fire safety problems have been the subject of many studies. ... 

The introduction of new fire safety standards and environmental regulations will mean a period of growth for the FR chemicals market and affect industries such as constmction, electronics and transport. 

The key driver for future growth will be fire safety and environmental regulations, which will demand the use of these chemicals in many more industries than before. This new legislation will also result in end-users changing the t3q)e of FR they buy to meet the latest specifications. This in turn will have a knock-on effect for the producers who will be forced to develop new products to keep pace and to serve the new markets and applications that will then be covered. 

The US Consumer Product Safety Commission (CPSC) has found that the outer cover fabric is the primary determinant of the initial growth of small open flame-ignited furniture fires. Injuries caused by these fires are principally those of children playing with lighters and matches. 

No regulations wae in effect that would have saved lives. The fire did lead to legislatbn requiring improved factory safety standards and helped spur the growth of the International Ladies Garment Workers Union and the Women s Trade Union League. 

Under these conditions, regulations impose the use of materials possessing thermal stability as well as efficient fire retardant properties. In parallel, emissions of smoke must be low, not very opaque, not very toxic, and not very corrosive. This evolution toward greater safety seriously limits the use of many materials and involves the rejection of solutions largely used so far and, in particular, halogen-based flame retardants, on account of environmental concerns. Moreover, analysis of various statistics on plastic consumption (180 MT/yr, with a global annual growth rate of approximately 8%) shows the economic importance of this field and illustrates the world s industrial stake in it.
