  • Course ObjectivesUpon completing this course, you will know how to:Recognize work-related routes of exposure to hazardous chemicalsIdentify and label chemical hazardsTake action to reduce exposure potentialDispose of chemical waste according to the Universitys waste management processPrepare for emergenciesIdentify revisions to the HazCom Std and their effective dates

  • Purpose of HCS to ensure that the hazards of all chemicals produced or imported are evaluated, and that information concerning their hazards is transmitted to employers and employees.You have a right to knowAbout the hazards in your workplaceHow to protect yourself from these hazards

  • OSHA Hazard Communication Standard RevisionTo align with the United Nations' Globally Harmonized System of Classification and Labeling of Chemicals

  • Effective Dates of Revised OSHA Hazard Communication Standard

    Effective Completion DateRequirement(s)WhoDecember 1, 2013Train employees on the new label elements and safety data sheet (SDS) formatEmployersJune 1, 2015Revise container labels and safety data sheets, SDSsChemical manufacturers, importers, distributors and employersJune 1, 2016Update alternative workplace labeling and hazard communication program as necessary, and provide additional training for newly identified physical and health hazardsEmployers

  • Hazardous Chemicals can pose a Health HazardAcute health hazards cause adverse health effects immediately or soon after the exposureUsually occur from a short term, high dose exposureChronic health hazards cause adverse health effects after years of multiple low dose exposureThey may cause measureable adverse changes in the body:

  • Sensitizers: cause an allergic skin or lung reactionLatex, chlorinated hydrocarbonsCarcinogens: may cause cancer.formaldehyde, methylene chlorideToxic & highly toxic agents: may cause adverse effects at low dosesIrritants: cause redness and swelling of the skin, eyes, respiratory tractacid gases, aromatic hydrocarbonsHazardous Chemicals can pose a Health Hazard

  • Corrosives: cause tissue damage and burns on contact with skin and eyeshydrofluoric acidTeratogens: may cause birth defectsOrgan Specific Hazards: may cause damage to specific organ systems such as the blood, liver, lungs, reproductive systemHazardous Chemicals can pose a Health Hazard

  • Hazardous Chemicals can pose a Physical HazardThey have a potential to cause harm because they are:Fire HazardsCombustible liquidsFlammable liquidsFlammable aerosolsFlammable gasesFlammable solidsOxidizersPyrophoricsExplosion HazardsCompressed gasesExplosivesReactive HazardsOrganic peroxidesUnstable (reactives)Water-reactives

  • Routes of Exposure to Chemical HazardsInhalation of dusts, fumes, mists, and vapors

    Skin absorption

    Ingestion of contaminated food and beverages through poor work habits

    Injection-usually associated with BBP

  • Exposure ConsiderationsMaintain concentrations of airborne contaminants as low as practical below established exposure limitsMost regulatory limits are maintained with a properly functioning fume hoodSingle digit and fractional exposure limits may require greater controlsEH&S can conduct personal exposure monitoring to determine exposure levels

  • Examples of OSHAs Personal Exposure Limits (in ppm)

    acetonitrile40benzene1 (0.5 action) (5 STEL)chloroform50 (ceiling)formaldehyde0.75 (0.5 action) (2 STEL)methanol200methylene chloride25 (12.5 action) (125 STEL)pyridine5

  • Hazard Identification

  • Safety Data Sheets, previously known as Material Safety Data SheetsA tool prepared by the manufacturer or importer outlining:Physical and chemical characteristicsHealth and physical hazard informationControl measuresEmergency, first aid, and spill proceduresProtective exposure limit(s)

  • SDS: What is my responsibility?Update your chemical inventory annuallyObtain a SDS for each hazardous material before it is usedEnsure the SDS file is readily accessible to employees when they are in their work areasChemical inventory lists and SDSs are exposure records, maintain either/both for 30 years after employment

  • Uniform Safety Data Sheet (SDS) format effective June 1, 2015Section 1, Identification includes product identifier;manufacturer or distributor name, address, phonenumber; emergency phone number; recommended use;restrictions on use.Section 2, Hazard(s) identification includes all hazardsregarding the chemical; required label elements.Section 3, Composition/information on ingredientsincludes information on chemical ingredients; trade secretclaims.Section 4, First-aid measures includes important symptoms/effects, acute, delayed; required treatment.Section 5, Fire-fighting measures lists suitable extinguishingtechniques, equipment; chemical hazards from fire.Section 6, Accidental release measures lists emergencyprocedures; protective equipment; proper methods ofcontainment and cleanup.Section 7, Handling and storage lists precautions for safehandling and storage, including incompatibilities.

  • Uniform Safety Data Sheet (SDS) format effective June 1, 2015Section 8, Exposure controls/personal protectionlists OSHAs Permissible Exposure Limits (PELs);Threshold Limit Values (TLVs); appropriate engineeringcontrols; personal protective equipment (PPE).Section 9, Physical and chemical properties lists thechemicals characteristics.Section 10, Stability and reactivity lists chemical stabilityand possibility of hazardous reactions.Section 11, Toxicological information includes routes ofexposure; related symptoms, acute and chronic effects;numerical measures of toxicity.Section 12, Ecological information*Section 13, Disposal considerations*Section 14, Transport information*Section 15, Regulatory information*Section 16, Other information, includes the date of

  • Sample of Revised Container Label, effective June 1, 2015

  • Standard Pictograms for container labels to alert users of chemical hazards effective June 1, 2015

  • Secondary Container LabelsMust provide:The identity and percent composition of the hazardous chemical componentsAppropriate hazard warningsThe name and address of the responsible partyThe hazard label message must be legible, permanently displayed and written in English.

    Rating Summary







    Rating Summary

  • Controlling Exposures

  • Elimination or SubstitutionEliminate the use of hazardous materials when possible

    Substitute with less hazardous materials, equipment, and processesUse ordinary detergents or enzymatic cleaners instead of dichromate/sulfuric acid mixturesUse digital or alcohol thermometers instead of mercury thermometers

    Reduce the quantities you purchase/use

  • Use Engineering ControlsInitial design specificationsChange the processPhysically change the machine or workenvironment to prevent exposuresEnclose the processIsolate the processUse ventilation

  • Tips for Effectively Using Fume HoodsKeep your lab doors closedAdjust the sash to the lowest level for convenient useWork at least six inches inside the face of the cabinetKeep the hood free of clutter, avoid use as chemical storageAvoid heating perchloric acid in regular fume hoodsPlace materials along the side panels, avoid placement in front of rear slots

  • Wash your handsDo not prepare, store, or consume food or beverages where hazardous chemicals are used or storedSecure compressed gas cylindersStore flammables in an approved cabinetsRegularly inspect and test peroxide-formersSegregate stored chemicals by hazard classUse secondary containment to transport chemicalsShield equipment from fire and explosion hazardsIncorporate Good Hygiene and Work Practices

  • Anticipate exposures Wear personal protective equipmentPPE is used if other controls cannot provide adequate protectionThe minimum PPE that should be worn while handling chemicals:GlovesSafety glasses/gogglesLab coat

  • Anticipate exposures Wear personal protective equipmentSelect chemical-resistant gloves based on the hazard. Avoid latex gloves!Have your lab coat professionally laundered.Ensure your eyewash is always accessible.

  • Contact EH&S if you are concerned about needing respiratory protectionAvoid respirators for routine lab work

    Before wearing a respirator, you must:Participate in additional trainingComplete a medical evaluationReceive a fit test

  • Dispose of Hazardous Chemical WasteFollow the procedures outlined in Advisory 7.3: Management of Chemical WastesComplete a waste labelEnsure waste is secure and store in an accessible areaNever drain dispose of hazardous chemicalsAvoid storing hazardous waste on the floorTriple rinse acute hazardous waste (P-list) containers before placing them in the dumpster, dispose of the rinsate as wasteLabel empty containers with the word EMPTY and take to the dumpster
