HAZARDOUS MATERIALSAWARENESS2019

PREFACEWelcome to the Hazardous Materials - Awarenesscertification course. This course complies with NFPA 472,Standard for Competence of Responders to HazardousMaterials/Weapons of Mass Destruction Incidents, 2018and with NFPA 1072, Standard for HazardousMaterials/Weapons of Mass Destruction EmergencyResponse Personnel Professional Qualifications 2017.Annual refresher training is required for all graduatesof this course in accordance with the code of federalregulations. Refresher training must be of sufficient contentand duration to maintain their certification, or the graduateshall demonstrate competency in those areas at leastyearly (i.e. HazMat exercise, multimedia training, classroomtraining, or participating in an actual HazMat emergencyresponse). This is a mandatory employer requirement tocomply with the law (29 CFR 1910.120-q-6)The State Emergency Response Commission requires 4hours per year of continuous education to retain certificationper year (i.e. HazMat exercise, multimedia training,classroom training, WMD training or participating in anactual HazMat emergency response).

Learning Objective 1Hazardous Materialsfor First RespondersFifth EditionDefine a hazardous materials incident.Chapter 1 — Introduction toHazardous Materials1–1Hazardous materials are substancesthat possess harmful characteristics.WMDs have the potential to causemass casualties and damage.WMD Weapons of Mass icalNuclear1–21–3Hazmat/WMD incidents poseunreasonable risks.ExplosiveHazmat incidents have manypotential causes.A hazardous materials/WMD incidentis an emergency involving substancesthat pose unreasonable risk toPotentialCauses ofHazmatIncidentsHuman errorMechanical breakdowns or malfunctionsContainer identsDeliberate acts1–4Chemical suicidesWMD incidents1–51

Container failure is one way that ahazmat incident may occur.Hazmat incidents are often morecomplex than other types of incidents.HazmatincidentsmayPresent a variety of dangers,sometimes in small quantitiesBe extremely difficult to containand/or controlCourtesy of Barry LindleyRequire specialized equipment,procedures, PPEBe difficult to detect, requiringsophisticated monitoring equipment1–61–7REVIEW QUESTIONCAUTIONHazardous materials incidents are notalways clearly defined before firstresponders arrive. You must beconstantly alert to the presence ofhazardous materials and their possibleeffects on the incident. Whetherinvolved or not, the mere presence ofhazardous materials may changeincident’s dynamics.How are hazardous materials incidentsdifferent from other types of emergencyincidents?1–8Learning Objective 2Describe roles and responsibilities of firstresponders in hazardous materialsincidents.1–101–9Hazmat first responders must safelyrespond to hazmat incidents.You must understandRole you playin theseincidentsYourlimitationsWhen youcannotproceed anyfurther1–112

Awareness level personnel might befirst to arrive at a hazmat incident.Awareness level personnel shouldtransmit, protect, and isolate.1–18Awareness level responders must beaware of clues to help them recognizehazardous materials.Clues thatmayindicate thepresence ofhazardousmaterialsLocationContainer shapeTransportation or facility markings1–19Awareness responders are notresponsible for planning the responseto a hazmat ering devicesMay provideinitial actionsto be takenSensory input such as odor, taste,appearance1–20Awareness personnel play animportant role at hazmat incident.Initial actions can affect course of incident for better or worseExpected to transmit information to appropriate authoritiesCall for appropriate assistanceInitiate protective actions1–21Ops level personnel respond to hazmatreleases as part of their normal duties.Operationslevelrespondersmust beable toID potential hazardsID response optionsImplement planned response tomitigate or control releaseEvaluate progress of actions takenIsolate hazardous area and deny entry1–221–234

REVIEW QUESTIONLearning Objective 3What are the three levels of hazmatresponders and what are theirresponsibilities?Recognize the ways that hazardousmaterials harm people.1–301–31Hazardous materials can hurt you invarious ways.You must understand hazmatincidents to safely mitigate them.Variety of hazardous materials you mayencounterMay cause harmby their behaviorand/or physicalpropertiesMay affect healthif they contact orget into you bodyPotential health effects of materialsPhysical hazards associated with them1–321–33Many hazardous materials havepotential health effects.Health affects may beAcuteChronic1–34Delayed1–356

Hazardous materials can enter thebody in multiple ways.Inhalation is the most commonexposure route.InhalationBreathinghazardousmaterials inthrough yournose or mouth1–36Poor hygiene can lead to accidentalingestion.Ingestion1–37Some materials easily pass throughskin and mucous membranes.AbsorptionEating orswallowinghazardousmaterials throughyour mouthTaking in materialsthrough your skinor eyes1–38Sharp objects can cut or punctureyour skin.1–39Hazardous materials can harm you inthree ways.InjectionTaking in materialsthrough apuncture in yourskin1–401–417

Energy release at hazmat incidentspresents the greatest threat.Heat (thermal) hazards are commonat hazmat incidents.Hazardous material can cause temperature extremesFires, explosions, burnsEnvironmental factors can cause heat illness,complicate hazmat operationsLack of heat can also cause harm1–42Heat and lack of heat can both causeharm.ThermalEnergyHazards1–43Objects possess mechanical energydue to their position or motion.Elevated temperature materialsExothermal reactionsFires and explosionsHot weatherCryogenic liquids and gasesResponders canbe injured byflying or fallingobjectsFriction injuriesmay occur –abrasions,blisters, burnsCold temperatures1–44Pressurized materials can releaseviolently.Hazardous material stored under pressureCan release violentlyMaterials may expand rapidly1–45Electrical hazards and electricitymay be present at hazmat ed containersElectrical equipment Portable generatorsPower toolsSpread hazards quickly over potentially large areas1–461–478
