1 University of Southern Indiana Chemical Safety on the Job
2 We use many chemicals… We want you to know how to use them safely You will learn about…The Hazards of ChemicalsOur Written ProgramHow Chemicals are LabeledSafe Use of ChemicalsMaterial Safety Data SheetsBasic Procedures for SpillsWho you can ask for more information
3 Hazards of Chemicals… There are 2 basic types of chemical hazards Physical HazardsHealth HazardsThe first rule of chemical safety is… "Know what you are working with and how to protect yourself and others“
4 Physical Hazards…Chemicals are classified as having Physical Hazards if they areExplosiveCompressed GasCombustible LiquidsFlammableUnstableWater ReactiveOxidizers
5 Physical Hazards…Some chemicals may be safe by themselves, but become dangerous when in contact with other substances.
6 Chemicals with Physical Hazards… Used only by trained employeesStored in a safe mannerNever mixed with other chemicals unless by an approved procedure
7 Health HazardsChemicals are classified as being a health hazard if they:Can cause cancerAre poisonous (toxic)Cause harm to your skin, internal organs, or nervous systemAre corrosive - such as acidsCause allergic reactions after repeated exposure
8 Chemicals can enter the body through: your lungs if you breath fumes, mists or dustyour skin if liquid or dust touches or spills on you or splashes in your eyesyour mouth if you eat after handling chemicalsaccidental swallowing of a chemical
9 Health Effects…Some chemicals affect specific organs such as your kidneys, liver, reproductive or nervous system.
10 Our Written Hazard Communication Program provides… Written information on hazardsLists chemicals we use and their hazardsSystem for ensuring chemicals are labeledMeans to ensure we have an Material Safety Data Sheet (MSDS) for each chemical
11 Our Written Hazard Communication Program… Lists who is responsible for the programProvides chemical specific safety training methodsTells you where to find chemical safety informationYou can see a copy of our written program by asking you supervisor
12 Labeling of Chemicals… Chemical labels provide information on Identity, Hazards and Safe UseAll chemical containers are labeled by the manufacturerOur company may place additional labels on the containers
13 Labeling of Chemicals… If chemicals are placed in another container, this new container must have a a label placed on it.All containers must be properly labeled
14 Uniform Labeling System… Our university “Uniform Labels” are used to ensure we have one labeling system.These may be placed on containers when chemicals are delivered to us or chemicals are transferred to other containers
15 2 Basic “Uniform Labels” HMIS - Hazardous Material Identification SystemNFPA - National Fire Protection AssociationBoth types must identify thechemical name and hazards
16 Uniform Labels…Pictures may be used to identify hazards and required protectionThis information may also be on the manufacturer’s label
17 HMIS and NFPA labels are very similar Both use colored boxes to identify specific hazardsNumbers or codes in the boxes tell you the hazard valuehigher number = higher hazard
18 NFPA and HMIS Label Colors Red - Fire HazardBlue - Health HazardYellow - Reactivity Hazard - explosive, unstableWhite - Special Hazards - corrosive, radioactive, water reactive, acid
19 NFPA Label..The purpose of the NFPA 704 labeling system is to provide a way of quickly identifying the various fire related hazards associated with a particular material. The NFPA 704 "diamond" is commonly found on bulk storage containers, but is also widely used on chemical containers and the MSDS.
20 NFPA Flammability Codes 4 Materials that will rapidly or completely vaporize at atmospheric pressure and normal ambient temperature, or that are readily dispersed in air and that will burn readily. Liquids with a flashpoint below 73ºF and a boiling point below 100ºF.
21 NFPA Flammability Codes 3 Liquids and solid that can be ignited under almost all ambient temperature conditions. Liquids with a flashpoint below 73ºF and a boiling point above 100ºF or liquids with a flashpoint above 73ºF but not exceeding 100ºF and a boiling point below 100ºF.
22 NFPA Flammability Codes 2 Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Liquids with flashpoint above 100ºF but not exceeding 200ºF.
23 NFPA Flammability Codes 1 Materials that must be preheated before ignition can occur. Liquids that have a flashpoint above 200ºF.0 Materials that will not burn.
24 NFPA Health Hazard Codes 4 Materials that on very short exposure could cause death or major residual injury.3 Materials that on short exposure could cause serious temporary or residual injury.
25 NFPA Health Hazard Codes 2 Materials that on intense or continued, but not chronic exposure could cause incapacitation or possible residual injury.
26 NFPA Health Hazard Codes 1 Materials that on exposure would cause irritation but only minor residual injury.0 Materials that on exposure under fire conditions would offer no hazard beyond that of ordinary combustible material.
27 NFPA Reactivity Hazard Codes 4 Materials that in themselves are readily capable of detonation or of explosive decomposition or reaction at normal temperatures and pressures.
28 NFPA Reactivity Hazard Codes 3 Materials that in themselves are capable of detonation or explosive decomposition or reaction but require a strong initiating source or which must be heated under confinement before initiation or which react explosively with water.
29 NFPA Reactivity Hazard Codes 2 Materials that readily undergo violent chemical change at elevated temperatures and pressures or which react violently with water or which may form explosive mixtures with water.
30 NFPA Reactivity Codes1 Materials that in themselves are normally stable, but which can become unstable at elevated temperatures and pressures.
31 NFPA Reactivity Codes0 Materials that in themselves are normally stable, even under fire exposure conditions, and which are not reactive with water.
32 NFPA Special Hazard Codes ACID = Acid ProductsALK = Alkali or BasesCOR = Corrosive ProductsOX = OxidizerW =Reacts with waterRadioactive
33 What do I do… if there is no label or I cannot read the label? STOP - do not use the chemicalTELL your supervisorREAD the MSDS and have another label put on the container
34 Chemicals can be safely used if… you know the hazards and how to protect yourselfthey are used only for approved purposesthey are stored properlyyou use the correct personal protective equipment
35 Chemicals can be safely used if… you do not eat in areas where chemicals are usedyou wash immediately if you come in contact with chemicals
36 Chemical Disposal…Each chemical and container must be disposed of properlyNo container is truly "empty" unless properly cleanedFollow MSDS requirements for container disposal
37 Chemical Disposal… Recycle unused chemicals Do not place hazardous chemicals in normal trash receptaclesDo not pour chemicals into sinks, onto the ground or in storm drains
38 Safe Storage… Store incompatible chemicals in separate areas Limit the amount of flammable material to the minimum neededStore flammable liquids in approved flammable storage lockers
39 Safe Storage… Store acids in separate flammable storage lockers Do not store chemicals in a refrigerator used for food storageDo not store food in refrigerators used for chemical storage
40 In case of an emergency… Implement the proper Emergency Action PlanEvacuate people from the areaIsolate the area-keep others from enteringTurn off ignition and heat sourcesOnly trained employees are permitted to clean up spills
41 Material Safety Data Sheets (MSDS) Show chemical safety informationEach chemical has a separate MSDSMSDS is written by the chemical manufacturerMSDS are kept in the workplace for your useIf you can't find an MSDS, ask your supervisor
42 Material Safety Data Sheets… are provided by the chemical manufacturer to provide additional information concerning safe use of the product.
43 Each MSDS tells you… 1. Common name and chemical name of the material 2. Name, address and phone number of the manufacturer3. Emergency phone numbers for immediate hazard information4. Date the MSDS was written
44 MSDS… 5. Hazardous ingredients 6. Physical and health hazards of the chemicals7. Identification of chemical and physical properties8. First aid / emergency information9. Safe handling and use information
45 MSDS… have specific hazard information on Fire and Explosion Chemical ReactionsControl MeasuresHealth HazardsSpill and Leak Procedures
46 MSDS Fire and Explosion Information Material flash point, auto-ignition temperature and upper/lower flammability limitsFire extinguishing agents to be usedFire fighting techniquesAny unusual fire or explosive hazards
47 MSDS Reaction Information Stability of Chemical..Conditions and other materials which can cause reactions with the chemicalDangerous substances that can be produced when the chemical reacts
48 MSDS Control MeasuresEngineering controls required for safe product usePersonal protective equipment required for use of productSafe storage requirements and guidelinesSafe handling procedures
49 MSDS Health HazardsPermissible exposure and threshold limits (PEL and TLV)Symptoms of exposureRoutes of entry into the bodyMedical conditions that can be made worse by exposureCancer causing propertiesEmergency and first aid procedures
50 MSDS Spill and Leak Procedures Clean up techniquesPersonal protective equipment to be used during cleanupDisposal of waste and cleanup material
51 Protecting Yourself…Personal Protective Equipment (PPE) may be needed to protect yourself from chemical hazardsUse the PPE our university has required for each chemicalCheck the PPE before use to make sure it is not damaged
52 Protecting Yourself…Use face shield and goggles if there is a splash hazardUse the proper respirator for dusts, mists and fumes
53 Protecting Yourself… Use the right gloves when handling chemicals Properly clean and store your PPE after useDon't take PPE home - why risk exposing your family?
54 Stay safe when using chemicals… Know what you are working withKnow where MSDS are located and how to use themAsk your supervisor if you have questionsOnly trained employees may use chemicals
55 Stay Safe… Make sure all containers are properly labeled Use the proper protective equipmentStore chemicals only in approved areasImmediately report leaks and spillsDispose of used chemicals and containers properly
