Hazardous Materials Incidents by Chris Hawley CHAPTER 3: Information Resources
Chapter 3: Overview • Introduction • Technical reference texts • Material Safety Data Sheets • Shipping papers • Facility documents • Computer resources • Chemtrec • Reference and information texts • Industrial technical assistance • Summary
Technical Reference Texts • Two common texts • DOT Emergency Response Guidebook • NIOSH Pocket Guide to Chemical Hazards
DOT Emergency Response Guidebook • Printed every 3-5 years by DOT • Provided to each emergency response vehicle nationwide • Covers commonly transported materials • General guide for first 30 minutes of incident
ERG Major Sections • Introduction • Placard, truck, rail guides • Listing by DOT Identification number • Alphabetical listing by shipping name • Response guides • Table of initial isolation and evacuation • List of dangerous water reactive materials
Common Abbreviations in the ERG • N.O.S. – Not otherwise specified • P.I.H. – Poison by inhalation • T.I.H. – Toxic by inhalation • P – Polymerization hazard • SCA – Surface contaminated articles (radiation) • LSA – Low specific activity (radiation) • PG I, II, or III – Packing group I, II or III • O.R.M. – Other regulated Material (listed as ORM A-E) • LC50 – Lethal concentration to 50% of the population • LD50 - Lethal dose to 50% of the population
Chemical Names • Chemicals have many different names. • Variation on chemical names • Trade names • Foreign names • Synonyms • Chlordane has more than 48 different names.
CAS Numbers • Chemical Abstract Service (CAS) registry service • Service registers chemicals with a specific number that can be equated to a social security number. • No matter the number of names, if they represent the same chemical, they will have one CAS number. • Numbers are in XXX-XX-XXXX format.
NIOSH Pocket Guide • National Institute Occupational Safety and Health (NIOSH) • Research arm of OSHA • Provides exposure levels and chemical information • Provides specific chemical and physical properties
Material Safety Data Sheets (MSDS) • Required by Hazard Communication Standard (HCS) • OSHA regulation • Commonly referred to as “Right to Know” • Required for chemicals above “household commodity” amounts • Employer required to keep MSDS on hand
MSDS • Employers must keep MSDS accessible for employees and emergency responders. • Annual training is required for MSDS, chemical listing, and emergency plan. • Information is for employee safety and handling. • There is no standard format.
Chemical identification Chemical composition Hazard identification Physical and chemical properties Stability and reactivity Toxicology Ecological information Disposal considerations Transportation information Regulatory information Elements of an MSDS
Shipping Papers • Who is shipping the material • Who is receiving the material • Emergency contact information • Number and weight of packages • Hazard or hazard class of material • Special notations
Shipping Paper Names • Airplane – Air bill • Highway- Bill of lading • Water (Ship) - Dangerous Cargo Manifest (DCM) • Railroad - Waybill and Consist
Computer Resources • Computer Aided Management for Emergency Operations (CAMEO) • Hazard information • Plume modeling • Facility and planning information • Chemical information databases • NIOSH Pocket Guide • Many others
Chemtrec • Sponsored by American Chemistry Council (ACC) • Maintains emergency response information provided by member companies • Maintains large stockpile of MSDSs • Great resource for emergency contacts • Transportation or facilities
