3 Some examples of Hazardous characteristics Some examples of Hazardous characteristics –Toxins ( poisons ) –Corrosives (eat skin and metal and wood) –Explosive/Reactive ( burns) –Flammable (liquids, solids and gas) –Oxygen Deprivation ( gases, confined space) –Cryogenic (intense cold) –Radioactive –Biological Hazards (living things, plants & animals)

4 Hazardous Materials Corrosives (have the ability to corrode metal or skin)Corrosives (have the ability to corrode metal or skin) –pH (Acids or Bases) Neutral pH 7 (less acidic, more basic)Neutral pH 7 (less acidic, more basic) Low pH (0-4) = Strong AcidLow pH (0-4) = Strong Acid High pH (11-14) = Strong Alkaline or Base (Caustic)High pH (11-14) = Strong Alkaline or Base (Caustic)

5 Hazardous Materials Toxins (or poisons)Toxins (or poisons) –Evidence of an acute or chronic health hazard Reactive MaterialsReactive Materials –Chemical substance that will vigorously polymerize, decompose, condense, or become self-reactive due to shock, pressure, or temperature. Includes explosive materials, organic peroxides, pressure-generating materials, and water-reactive materials. (Violent Reaction alone, from shock/physical factors, or with air or water) OxidizersOxidizers –Substance that yields oxygen readily to stimulate the combustion of organic matter

6 Hazardous Materials FlammablesFlammables –a liquid with a flash point below 100 degrees F Flammable Gas:Flammable Gas: –Gas that at ambient temperature and pressure forms a flammable mixture with air Flammable Limits:Flammable Limits: –Minimum and maximum concentrations of flammable gas or vapor between which ignition occurs.

7 Hazardous Materials FLAMMABLE LIQUIDS:FLAMMABLE LIQUIDS: –Liquid that gives off vapors that can be ignited at room temperature; liquid with flash point below 100F. FLAMMABLE SOLID:FLAMMABLE SOLID: –Solid that will ignite readily and continue to burn or is liable to cause fires under ordinary conditions or during transportation through friction or retained heat from manufacturing or processing and that burns so vigorously and persistently as to create a serious transportation hazard.

8 Chemical Hazards Physical - Fire & ExplosivePhysical - Fire & Explosive Health - Effects on the body.Health - Effects on the body. –Acute - Rapid on-set of symptom. Effect experienced soon after exposure.Effect experienced soon after exposure. A lethal acute dose can cause immediate death. A lethal acute dose can cause immediate death. –Chronic – Adverse effect that develops slowly over a long period of time or that recurs frequently. Gradual on set of effect or symptoms, a latency period, or cumulative effects of small doses.Gradual on set of effect or symptoms, a latency period, or cumulative effects of small doses. Cancer is an example of a chronic effectCancer is an example of a chronic effect

9 How hazardous materials can harm you: Exposure Pathways Inhalation (lungs)Inhalation (lungs) Absorption / Contact (e.g. skin/eyes)Absorption / Contact (e.g. skin/eyes) Swallowing (more than one means)Swallowing (more than one means) Injection (sub dermal - needles, slivers, under nails, puncture wounds)Injection (sub dermal - needles, slivers, under nails, puncture wounds) Radiant penetrationRadiant penetration

10 Work smart Do your job in a way that protects yourselfDo your job in a way that protects yourself –Minimize your risk of exposure –Minimize the risk of a hazardous spill Be Aware! Be Alert! Be Alive!

11 IS there a hazard? How do you know? Get as much information as you can:Get as much information as you can: What is the substance?What is the substance? How does it harm?How does it harm?

23 MSDS: What on earth is THAT!?! MaterialMaterial SafetySafety DataData SheetSheet

24 MSDS Material Safety Data SheetsMaterial Safety Data Sheets –Provided by the product manufacturer as required by law. –Should come with new shipments of materials. –Copies should be located in your work area. Review these for the products you work withReview these for the products you work with

25 MSDS uInformation About the Material uHealth Effects, Routes of Entry & Protective Measures uHealth Hazard of Substance & First Aid uEmergency Response Procedures uEnvironmental Release Data

26 MSDS SECTIONS 1Chemical Product & Company Information 2Composition, Information on Ingredients 3Hazards Identification 4First Aid Measures 5Fire Fighting Measures 6 Accidental Release 7 Handling & Storage 8 Exposure Controls, Personal Protection 9 Physical & Chemical Properties 10 Stability & Reactivity

27 MSDS SECTIONS cont.. 11 Toxicological Information 12 Ecological Information 13 Disposal Consideration 14 Transport Information 15 Regulatory Information 16 Other Information

28 So how do you know if it is hazardous if there are no labels? You dont! But……. If you know what it is… consider the chemical properties

29 What if you are still not sure… If you need to err where life and safety are concerned how do you err…? On the side of safety Ask your supervisor or your safety trainer

30 Chemicals are risky unless… You decide now to do the right thing by YOURSELF Find and read your MSDS Label and only use labeled containers Know what to do to prevent and take care of splashes and spills AND DO IT!!!

31 If there is a Hazard How do you work with the stuff safelyHow do you work with the stuff safely When do you get help (see your supervisor)When do you get help (see your supervisor) What do you do if you are exposed (get it on you)What do you do if you are exposed (get it on you)

32 Safe Chemical Handling Never mix chemical productsNever mix chemical products Note the storage requirements, precautions and any temperature restrictionsNote the storage requirements, precautions and any temperature restrictions Store non-compatible products separatelyStore non-compatible products separately Ensure you have proper ventilation and be aware of what others are usingEnsure you have proper ventilation and be aware of what others are using Wear the proper PPE for the chemical being used.Wear the proper PPE for the chemical being used.

39 First Responders ResponsibilityFirst Responders Responsibility –Identify if hazard exists –Call for Assistance Supervisor, Environmental Health and Safety, PoliceSupervisor, Environmental Health and Safety, Police –Provide good information on hazard –Contain spill if you can without risk, –Provide first aid if you can without risk –Secure site and evacuate area as needed –Call dispatch for help If you come across a spill…

40 Proper Disposal of Chemical Hazardous waste Chemical containers – including spray cans – should be empty prior to proper disposal.Chemical containers – including spray cans – should be empty prior to proper disposal. Never discard unwanted chemicals in the sink or floor drain (unless you are certain they are not hazardous).Never discard unwanted chemicals in the sink or floor drain (unless you are certain they are not hazardous). EHS will pick up un-wanted hazardous materials from your work site.EHS will pick up un-wanted hazardous materials from your work site. –Call or for information and to arrange a pick-up.
