EMERGENCY RESPONSE RESOURCES
Chemical substances that have the ability to create a physical or health hazard are considered hazardous. Due to their properties chemical hazardous substances may be, but are not limited to being toxic, explosive, flammable, self-reactive, oxidizing, or corrosive. Exposure to these substances by different routes including inhalation, dermal absorption, or ingestion can lead to adverse health effects, enhancing the need to know about the hazards associated to these substances beforehand.
Chemical agent information is needed for emergency response and recovery workers to appropriately plan for risks resulting from possible chemical incidents. Several organizations have developed information databases, including short-term and long-term criteria, each with specific purposes, exposure scenarios, and severity of adverse health effects considered in their development.
Databases offer their users the possibility to consult by name, the properties, physical descriptions, exposure routes, target organs, associated symptoms in case of exposure, personal protection recommendations, standards, and first aid for a particular chemical.
This webpage offers a variety of resources containing chemical agent information open to employers and workers to consult and plan appropriately for risks of exposure to potential hazardous chemicals.
The following databases provide detailed information on a variety of chemical agents associated with emergency response. Information provided includes types of agents, agent characteristics, physical and chemical properties, CAS, common names, decontamination recommendations, health effects, occupational exposure limits, symptoms of exposure, and first aid recommendations depending on the type of chemical agent.
Emergency preparedness and Response databases
- The following database was developed by NIOSH for the emergency response community. The Emergency response safety and health database (ERSH-DB) provides information associated to potential hazards emergency response and recovery workers might find when responding to a terrorist event. The data base contains accurate and concise information on high-priority chemical, biological and radiological agents and provides multiple search fields such as agent category, characteristics, name, long-term implications, symptoms, and personal protective equipment.
The Emergency Response Safety and Health Database (ERSH-DB)
- The following website presents a list of chemical agents organized by alphabetically order presenting facts of each agent, descriptions of the chemicals, emergency response information from CDC related to specific chemical agents, toxic syndrome descriptions, and emergency response cards containing decontamination, disposal, use of personal protective equipment, and sampling information.
Public Health Emergency Preparedness and Response (CDC) Chemical Agents List A-Z
- The Pocket Guide is a source of general industrial hygiene information that contains data of several hundred chemicals and hazards that can be potentially found in the work environment. Key data provided for each substance includes name (synonyms, trade names), structure, formula, Chemical Abstracts Service (CAS) Numbers, conversion factors, exposure limits, chemical and physical properties, measurement methods, personal protection, respirator recommendations, symptoms, concentrations that are immediately dangerous to life or health (IDLH), and first aid.
NIOSH Pocket Guide to Chemical Hazards
- The International Chemical Safety Cards offer essential health and safety information on chemicals to promote their safe use. They are intended to be used by workers and employers as a clear communication tool. The information provided in these cards includes identity of the chemical, physical and chemical properties and hazards, fire and explosion hazards, health hazards and how to prevent them, first aid, spillage disposal, storage and packaging, and classification and labelling.
International Chemical Safety Cards
- The Medical Management Guidelines (MMGs) for Acute Chemical Exposures were designed to aid emergency department physicians and other emergency healthcare professionals who manage acute exposures resulting from chemical incidents. The intention of these guidelines is to support the labor of healthcare professionals involved in emergency response during decontamination processes. The guidelines also aim to provide responders with guidelines on how to protect themselves and others from contamination, communicate with other involved personnel, efficiently transport patients to a medical facility, and provide competent medical evaluation and treatment to exposed patients. The document covers basic chemical and exposure information, potential health effects and emergency management information.
Medical Management Guidelines
- Toxnet is a search engine that provides access to several databases on toxicology, hazardous chemicals, environmental health, and toxic releases provided by the National Library of Medicine. Toxnet contains databases with peer reviewed toxicology data for multiple hazardous chemicals, drugs and lactation databases, developmental toxicology literature, chemical releases and mapping information, genomics data, household product safety advice, occupational exposure to chemicals information, risk assessment, animal testing alternatives and carcinogenicity and mutagenicity information.
- The Agency for Toxic Substances and Disease Registry (ATSDR) produces “toxicological profiles” for hazardous substances that have been found in National Priorities List (NPL) sites. These profiles are a compilation of toxicological information available on a particular substance. Besides the general information such as chemical and physical information, the profile includes health effects, toxicokinetics, susceptible populations, biomarkers, potential of human exposure, regulations, and advisories.
- The ATSDR ToxFAQs™ is a series of summaries about hazardous substances containing toxicological information for each particular chemical substance. Each fact sheet provides information about potential exposure routes to a chemical, describes the substance and its implications in the environment and in human health. Additionally provides information regarding its carcinogenic potential and describes recommendations to protect human health. This document serves as a quick and easy guide to understand the use and exposure to chemical substances.
- The interaction profiles are a series of documents developed for certain priority mixtures. The purpose of the Interaction Profile is to evaluate toxicology data available for the mixture (if available) and on the joint toxic action of the chemicals in the mixture, aiming to recommend approaches for the exposure-based assessment of the potential hazard to public health. These interaction profiles provide an explanation of the mixture of concern and how each component of the mixture can affect human health depending on their individual chemical and physical properties as well as their interaction.
Toxicology Interaction Profiles
- Acute Exposure Guideline levels (AEGL) are Environmental Protection Agency recommended criteria intended to describe the potential health effects different types of exposures could have in human health. This levels include the risks of exposure resulting from once-in-a-lifetime or rare exposures to airborne chemicals. The National Advisory Committee for the Development of Acute Exposure Guideline Levels for Hazardous Substances (AEGL Committee) is involved in developing these guidelines to help both national and local authorities, as well as private companies, deal with emergencies involving spills, or other catastrophic exposures. The following page provides an overview of AEGLs, presents chemical priority lists and lists AEGLs by chemical name, CAS number or AEGL status.
