Toxic spills

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.

Great care should be taken with the use of mercury on account of its toxicity. Spills should be dealt with immediately and mishaps avoided by the use of trays placed under the apparatus. Additionally, the laboratory should be well ventilated.

Bleachex manufactures a variety of products using concentrated acids and bases. Plant officials noticed a large quantity of liquid, which was believed to be either sodium hydroxide or hydrochloric acid solution, flowing through the loading bay doors. An Emergency Toxic Spill Response Team attempted to determine the source and identity of the unknown liquid. A series of explosions and the presence of chlorine gas forced the team to abandon its efforts. The unknown liquid continues to flow into the nearly full containment ponds. 

January 20, 1997- Toxic spill in the 90-day storage yard improperly cleaned up. Haz-mat team called back to the plant prior to clean-up in "order to continue processing." Toxic material snow-plowed against the boundary fence and left.

ASIMO might also be able to complete tasks that are too dangerous for people such as cleaning up toxic spills or fighting fires. What a wonderful assistant that would be. 

A number of models exist for analysis of toxic spills, and in recent years we have seen numerous advances in the state of the art. This article reviews current ability to model toxic spills into waterways, including limitations. The basic equations are reviewed, along with a definition of the coefficients required. Methods of solutions to the equations are presented, along with specific presentations of some existing models of potential usefulness. An example is also presented. Emphasis throughout is on practical application, but a clear understanding of equation development and coefficient definition is needed to avoid some of the errors made in the past.

Segregation of Waste Streams — The segregation of waste streams permits recovery of heavy metals, caustic recovery and reuse, and control of toxic spills (such as dieldrin used for moth-proofing). Many of the older textile mills have a common collection system with chemical reuse, but the modem mills have a segregated collection system to permit chemical recovery and reuse.
