Emergency containment

Provide for addition of diluent, poison, or inhibitor directly to reactor. Provide for automatic or manual actuation of bottom discharge valve to drop batch into a dump tank with diluent, poison or inhibitor, or to an emergency containment area. 

Good housekeeping Keep toxicants and dusts contained. Use dikes around tanks and pumps. Provide water and steam connections for area washing. Provide lines for flushing and cleaning. Provide well-designed sewer system with emergency containment. 

This section will describe clinical practice and research concerning methods for reducing toxic effects of exposure to chlorine dioxide or chlorite. However, because some of the treatments discussed may be experimental and unproven, this section should not be used as a guide for treatment of exposures to chlorine dioxide or chlorite. When specific exposures have occurred, poison control centers and medical toxicologists should be consulted for medical advice. Standard texts that discuss treatment of toxicologic emergencies contained no information concerning chlorine dioxide or chlorite. 

Several appropriate emergency container leak repair kits should be stored near the chlorine application facility. 

It has been shown by Walsh et that the periodicity of the duplex, one of the main secondary structural elements of nucleic acid, is reflected in its RDCs. Since there are many more residues per turn in nucleic acids than in proteins, detailed features of the RDC wave emerge containing information on the orientation of both the secondary structure element and individual bond vectors. 

Assessment of tertiary containment should start with an initial worst-case assumption that available secondary containment will fail or capacity will be exceeded, and the consequent firewater flows and directions should be identified and estimated. Based on this, implementation of basic good practice measures should be considered, for example site kerbing/banking, sleeping policemen/ramps, permanent or temporary measures to close off potential environmental pathways and/or direct flows, and temporary emergency containment provision. This could include the provision of pollution containment equipment, for example pipe-blockers, drain sealing mats and land booms. 

There are a variety of emergency containment measures that may be used including ... 

A wide variety of off-the-shelf products are available to deal with spillages or to contain spills in emergency containment areas. Any materials or equipment used must be located at accessible positions which are clearly marked with durable notices explaining their use. In addition, any equipment must be fit for the purpose and effectively well maintained ready for use. The pollution incident response plan will identify the pollution prevention equipment and materials and their location. The type of materials and equipment that may be provided to mitigate the effects of a fire on the environment include ... 

A primary and a secondary water circuit is used to cool the bar before it is cut (at 13 meters). In the case of an emergency (if the cooling system does not work, the mold overflows, the tundish or ladles break), the casters must try to make use of emergency furrows to collect the steel and slag in emergency containers and must close the tundish nozzles using copper stoppers.
