Book Description
Chlorine dioxide (ClO2) exists as a greenish yellow to orange gas at room temperature. It is used in the paper and pulp bleaching industries as a sterilizing agent, in hospitals as a biocide in water treatment, and as an improving agent in flour. This document focuses on exposures via routes relevant to occupational settings principally related to the production of chlorine dioxide, but also contains environmental information. The health effects and environmental fate and effects of chlorine dioxide used in the treatment of drinking-water, together with those of halogenated organics produced by the interaction between the disinfectant and other materials present in the water are covered in a recent Environmental Health Criteria publication (EHC No. 216 2000) and are not dealt with in detail here. Chlorine dioxide is an irritant and it seems likely that health effects would be restricted to local responses. The few ecotoxicity data available show that chlorine dioxide can be highly toxic to aquatic organisms.

Management of Legionella in Water Systems
Author: National Academies of Sciences, Engineering, and Medicine
Publisher: National Academies Press
ISBN: 030949382X
Category : Medical
Languages : en
Pages : 291
Book Description
Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.

Publisher: Simon and Schuster
ISBN: 1626363765
Category : House & Home
Languages : en
Pages : 352
Book Description
Does the identification number 60 indicate a toxic substance or a flammable solid, in the molten state at an elevated temperature? Does the identification number 1035 indicate ethane or butane? What is the difference between natural gas transmission pipelines and natural gas distribution pipelines? If you came upon an overturned truck on the highway that was leaking, would you be able to identify if it was hazardous and know what steps to take? Questions like these and more are answered in the Emergency Response Guidebook. Learn how to identify symbols for and vehicles carrying toxic, flammable, explosive, radioactive, or otherwise harmful substances and how to respond once an incident involving those substances has been identified. Always be prepared in situations that are unfamiliar and dangerous and know how to rectify them. Keeping this guide around at all times will ensure that, if you were to come upon a transportation situation involving hazardous substances or dangerous goods, you will be able to help keep others and yourself out of danger. With color-coded pages for quick and easy reference, this is the official manual used by first responders in the United States and Canada for transportation incidents involving dangerous goods or hazardous materials.

The Microbiological Safety of Low Water Activity Foods and Spices
Author: Joshua B. Gurtler
Publisher: Springer
ISBN: 1493920626
Category : Technology & Engineering
Languages : en
Pages : 437
Book Description
Low water activity (aw) and dried foods such as dried dairy and meat products, grain-based and dried ready-to-eat cereal products, powdered infant formula, peanut and nut pastes, as well as flours and meals have increasingly been associated with product recalls and foodborne outbreaks due to contamination by pathogens such as Salmonella spp. and enterohemorrhagic E. coli. In particular, recent foodborne outbreaks and product recalls related to Salmonella-contaminated spices have raised the level of public health concern for spices as agents of foodborne illnesses. Presently, most spices are grown outside the U.S., mainly in 8 countries: India, Indonesia, China, Brazil, Peru, Madagascar, Mexico and Vietnam. Many of these countries are under-developed and spices are harvested and stored with little heed to sanitation. The FDA has regulatory oversight of spices in the United States; however, the agency’s control is largely limited to enforcing regulatory compliance through sampling and testing only after imported foodstuffs have crossed the U.S. border. Unfortunately, statistical sampling plans are inefficient tools for ensuring total food safety. As a result, the development and use of decontamination treatments is key. This book provides an understanding of the microbial challenges to the safety of low aw foods, and a historic backdrop to the paradigm shift now highlighting low aw foods as vehicles for foodborne pathogens. Up-to-date facts and figures of foodborne illness outbreaks and product recalls are included. Special attention is given to the uncanny ability of Salmonella to persist under dry conditions in food processing plants and foods. A section is dedicated specifically to processing plant investigations, providing practical approaches to determining sources of persistent bacterial strains in the industrial food processing environment. Readers are guided through dry cleaning, wet cleaning and alternatives to processing plant hygiene and sanitation. Separate chapters are devoted to low aw food commodities of interest including spices, dried dairy-based products, low aw meat products, dried ready-to-eat cereal products, powdered infant formula, nuts and nut pastes, flours and meals, chocolate and confectionary, dried teas and herbs, and pet foods. The book provides regulatory testing guidelines and recommendations as well as guidance through methodological and sampling challenges to testing spices and low aw foods for the presence of foodborne pathogens. Chapters also address decontamination processes for low aw foods, including heat, steam, irradiation, microwave, and alternative energy-based treatments.

Reopening Public Facilities After a Biological Attack
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309165059
Category : Political Science
Languages : en
Pages : 224
Book Description
The anthrax attacks in fall 2001 spurred an extensive and costly decontamination effort where many decisions had to be made about which sites required cleanup, what method to use, how to determine the effectiveness of the cleanup, and how "clean" the building had to be for reoccupation. As part of a project funded by the U.S. Department of Homeland Security (DHS), and managed by Lawrence Livermore National Laboratory, the National Research Council was asked to consider the criteria that must be met for a cleanup to be declared successful, allowing the reoccupation of a facility. The report finds that efficiently sampling and characterizing a pathogen is critical for choosing the best remediation strategy. However, there should be no universal standard for deciding when a building is safe to re-enter because varying pathogen amounts and characteristics could require different strategies. The report offers a flowchart for decision-makers that includes questions about the characteristics of the pathogen; how far it has spread; whether it is transmissible between humans; and how long it will survive to pose a threat. The report also recommends that a risk-assessment approach be adopted as part of a strategy for achieving a "socially acceptable" standard for cleanup.
