8New York City Fire Department Certificate of Fitness ProgramAt least one C of F holder is required per lab while the laboratory is in operation (includes nights & weekends).holder knows emergency procedures in the event of a fire in the lab.Labs with large amounts of compressed gases or cryogenics may require additional Certificates.Contact EH&S for information on obtaining a C of F.
9The Occupational Safety and Health Administration (OSHA) Regulates workplace health and safetyOSHA Laboratory Standard (29 CFR ) :Information on hazard identification and protectionInformation on chemical exposure, detection, and managementEmergency proceduresEmployers’ and employees’ rights and responsibilitiesis the specific regulation that applies to laboratory environments
10Hazard Recognition“The employer shall provide employees with information and training to ensure that they are apprised of the hazards of chemicals present in their work area.” 29CFRSafety and hazard information is available from multiple sources.
11Hazard Recognition Sources of hazard information: USDOT (Department of Transportation) DiamondsNFPA (National Fire Prevention Association) DiamondsManufacturers’ labelsMaterial Safety Data Sheets (MSDS)Office of Environmental Health & Radiation Safety/ Environmental Health & Safety
12Hazard RecognitionChemicals are often marked with the NFPA Diamond or similar hazardous communication markings to denote their hazards.Note the hazards as listed on chemical containers in your lab prior to using them.
13Material Safety Data Sheets (MSDS) Shipped with all chemicalsAll safety informationexposure limitsprecautions for safe handling and useother hazard informationMust be accessible (paper copy or via internet) in the lab for all chemicals present.
14Hazard Recognition -Physical & Chemical Hazards Awareness of the potential riskKnowledge about the hazardPrecautions and protective measuresBurnsAsphyxiationSlips, Trips, FallsElectrocutionBlunt Force Trauma, LacerationsCompressed Gas and Cryogenic HazardsFlammabilityCorrosivityToxicityReactivityPhysical hazards may be present in laboratories and cover a wide range of concerns including the following:Cuts, Slips, Trips, and Falls. Broken glassware is a frequent cause of cuts in laboratories. Water on the floor, especially around sinks or ice dispensers may cause slips.Compressed GasesAlthough compressed gases may have chemical hazards associated with them, physical hazards include asphyxiation and rupture of the tank.Non-flammable CryogensLiquid nitrogen is the most widely used non-flammable cryogen. Such materials may cause tissue damage or asphyxiation in poorly ventilated areas. Liquid oxygen condensation in vacuum traps may cause explosion.High Pressure ReactionsEquipment failure can lead to explosion at pressures over one atmosphere.Vacuum WorkWork in vacuum lines and at subambient pressure includes the danger of glass breakage, implosion, and flying glass particles.Ultraviolet, Visible, and near-Infrared RadiationUse of lamps and lasers in the laboratory can cause substanitial eye damage.Radiofrequency and Microwave HazardsThese occur within the range of 10 kilohertz to 300,000 megahertz. Microwave ovens may cause super heating of liquids. Metals in ovens may cause arcing. Capping of vials in the oven can result in explosion from pressure build up.Electrical HazardsElectrical equipment usually found in laboratories have safety features incorporated into their design and construction, but these features should not be defeated. Electrical malfunctions can lead to electrical fires, and may also ignite flammable vapors.Magnetic FieldsNMR spectrometers and other instruments generate large magnetic fields. While the field strength fall off rapidly with distance, there is evidence that at fields above 50 to 100 gauss ferromagnetic objects moved too close to the magnet may become projectiles aimed at the magnet.
15Oxygen AlarmsOxygen alarms are used where large amounts of cryogenics or inert gases are stored, which can potentially cause asphyxiation by displacing oxygen.DO NOT ENTER any area where an oxygen alarm is going off.Asphyxiation can be rapid and sudden, with no warning signs.Rescues must be performed by someone with a supplied air respirator.If it is possible to open doors/windows to ventilate area without entering, do so.
16POTENTIAL OXYGEN DEFICIENCY HAZARD DANGER If you hear Alarm, DO NOT ENTER; Call Public Safety During Work hours also call EH&SPOTENTIAL OXYGEN DEFICIENCY HAZARDIf Alarm is ActivatedAssume alarm activation to be validEvacuate all workers in room and close the doorCall Public Safety immediately; also PI and EH&SBe prepared to provide information to respondersDO NOT Enter the roomDO NOT Attempt to rescue anyone, as asphyxiation can be rapid with no warning signsDO NOT Open door within first hour after the alarm has stopped soundingDo NOT attempt to repair a faulty sensor. Report it to TechAir ( ) or EH&S.Review Columbia University policy (www.ehs.columbia.edu/OxygenDeficiency).

19Exposure Management - Chemical Routes of Entry InhalationAbsorptionInjectionIngestion
20Chemical Routes of Entry A common route of chemical exposure is ingestion due to contaminated food or hands.
21Chemical Exposure – Health Effects Acute effects – sudden, traumatic effectsHeadaches, dizziness, burns from corrosive chemicalsChronic effects – slow, gradual effects not rapidly perceived; poor or no warnings of exposureCancer, mutation, reproductive effects
22Chemical Exposure - Exposure Limits Risk = Exposure x HazardToxic effects can be minimized by keeping exposures to a minimum.Acceptable limits of exposure
23QuestionEating or drinking in a laboratory is strictly prohibited but acceptable in other areas where toxic/harmful chemicals are stored?FALSE
24Exposure Management Hierarchy of control measures to minimize risk. Reduce time or amount of exposure, or alter nature of exposure.Engineering controlsAdministrative controlsPersonal protective equipment (PPE)Engineering controls are measures designed to prevent exposure to a harmful substance or hazard. The most common engineering controls are:Chemical Fume HoodsBiosafety Cabinets
25Engineering Controls - Chemical Fume hoods Reduce exposure to airborne hazards.Ensure that your fume hood is:Free of clutterlfm‘Kim-wipe test’Not open more than 12”
28Exposure Management - Administrative Controls Alter work practices:Chemical substitutionProper storage and segregation of hazardous materialsProper housekeeping practicePrudent inventory and purchase order managementAppropriate training and Right to Know information (such as MSDS)
29Administrative Controls – Chemical Substitution Less hazardous alternativesCitrosolv v. xyleneEnzymatic detergents v. chromic/sulfuric acid-based glass cleanersSYBR Safe v. ethidium bromideAn effective way to reduce exposure to a hazardous material is to remove it from your work practice entirely. Consider the use of safer chemical alternatives when designing your experiments.
30Administrative Controls – Chemical Substitution Mercury is a TOXIC metal. Clean-up is time and resource-intensive.
31Administrative Controls - Chemical Storage Proper chemical storage reduces exposure risk.SegregationHazard ClassIncompatiblesdeep spill bins or separate cabinetsLabelingAll containers, including reaction vessels.
32Administrative Controls - Chemical Storage Consider the following:Compatibilitycontainer and cabinet with chemicalsProximitychemicals, incompatible materials, heat, or open flame
35Administrative Controls – Chemical Storage (Flammables) Allowable limit of flammable materials.Determined by construction materials and presence of sprinklers.4 Lab types: I, II, III, IVFlammable limits of 30, 25, 20, 15 gallons, respectivelyFlammable waste materials count toward these limits
36Administrative Controls – Chemical Storage (Flammables) Explosion-proof or intrinsically-safe refrigerators
37Administrative Controls - Housekeeping Poor housekeeping contributes to accidents and can hinder emergency response activities.Do not:block exits, aisles, or doorways.block access to emergency equipment.store chemicals in excess of lab’s limts.store chemical containers on the floor.
39What is wrong with this? Clutter Open Sash Open Bottle Labeling Exposed Sharps ObjectsNot Properly Managed
40What is wrong with this? Excess chemical on the workbench Poor housekeeping
41Administrative Controls - Inventory Management Purchase order managementSmallest quantity sufficient for your workUtilize ‘just in time’ deliveryExcess chemicals become Hazardous WasteUpdated chemical inventoryDispose of all outdated or unused chemicals properly and promptly.present in the laboratory should be prepared, updated, and maintained in the laboratory.
43Personal Protective Equipment - Eye Protection Determined by risk factorsSafety glasses provide basic protectionmust be worn when handling hazardous materials.Safety gogglessplash hazards or highly corrosive materialsLaser goggleswavelength-specific protection, with opaque non-lens components to protect the face.
44Personal Protective Equipment - Hand Protection No one glove protects against all chemicals.Consult manufacturers’ guidesNever re-useChange frequentlycontaminated or torn
45Personal Protective Equipment - Hand Protection DO NOT TOUCH DOOR KNOBS OR ELEVATOR BUTTONS
46Personal Protective Equipment - Lab coats Limited but critical protection from chemical splashes.Small (i.e., research sized) quantities of hazardous chemicals.Dispose or launder if heavily contaminatedKeep coat buttoned to prevent entanglement in moving equipment.
