2 1 Laboratory Safety & Hazardous Waste Training

3 2 Agenda  Laboratory Safety —Regulatory Introduction –Hazard Recognition Physical Chemical –Exposure Management Engineering Controls Administrative Controls –Material Segregation and Management Personal Protective Equipment –Fire Safety and Procedures –Spills and Emergency Response  Hazardous Waste Management

4 3 Regulatory Introduction Columbia University laboratories must comply with rules set by the following regulatory bodies:  New York City –Fire Department (FDNY) –Department of Environmental Protection (DEP)  New York State –Department of Environmental Conservation (NYSDEC)  Federal –Department of Labor: Occupational Safety and Health Administration (OSHA) –United States Environmental Protection Agency (USEPA)

5 4 Peroxide-Forming Chemicals  Must be dated immediately upon opening  Discard any unused chemicals within a year of opening date  Ethers, THF and dioxanes New York City Fire Department

6 5 New York City Fire Department Compressed gas cylinders  Stored upright and restrained.  Oxygen cylinders should be kept at a minimum of 25 feet away from flammable gas cylinders.  i.e. hydrogen

7 6 New York City Fire Department Flammables in Refrigerators  Flammable chemicals must be stored in a “Flammable Material Storage” or “Explosion Proof” refrigerator  Domestic refrigerators located in labs are labeled “Store No Flammables Flashing below 100 F”.

8 7 New York City Fire Department Chemical containers must be Clearly and Visibly labeled to indicate their contents at all times.

9 8 Certificate of Fitness Program  At 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. New York City Fire Department

10 9 The Occupational Safety and Health Administration (OSHA)  Regulates workplace health and safety  OSHA Laboratory Standard (29 CFR ) : –Information on hazard identification and protection –Information on chemical exposure, detection, and management –Emergency procedures –Employers’ and employees’ rights and responsibilities

11 10 Hazard 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.” 29CFR –Safety and hazard information is available from multiple sources.

12 11 Hazard Recognition Sources of hazard information:  USDOT (Department of Transportation) Diamonds  NFPA (National Fire Prevention Association) Diamonds  Manufacturers’ labels  Material Safety Data Sheets (MSDS)  Office of Environmental Health & Radiation Safety/ Environmental Health & Safety

13 12 Hazard Recognition  Chemicals 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.

14 13 Material Safety Data Sheets (MSDS)  Shipped with all chemicals –All safety information exposure limits precautions for safe handling and use other hazard information  Must be accessible (paper copy or via internet) in the lab for all chemicals present.

15 14 Hazard Recognition -Physical & Chemical Hazards  Awareness of the potential risk  Knowledge about the hazard  Precautions and protective measures –Burns –Asphyxiation –Slips, Trips, Falls –Electrocution –Blunt Force Trauma, Lacerations –Compressed Gas and Cryogenic Hazards –Flammability –Corrosivity –Toxicity –Reactivity

16 15 Oxygen Alarms  Oxygen 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.

17 16 DANGER If you hear Alarm, DO NOT ENTER; Call Public Safety During Work hours also call EH&S POTENTIAL OXYGEN DEFICIENCY HAZARD If Alarm is Activated Assume alarm activation to be valid Evacuate all workers in room and close the door Call Public Safety immediately; also PI and EH&S Be prepared to provide information to responders  DO NOT Enter the room  DO NOT Attempt to rescue anyone, as asphyxiation can be rapid with no warning signs  DO NOT Open door within first hour after the alarm has stopped sounding  Do NOT attempt to repair a faulty sensor. Report it to TechAir ( ) or EH&S.  Review Columbia University policy (

18 17  What type of refrigerator is required for storage of flammable chemicals?  Peroxide forming chemicals must be upon opening. Questions

19 18 Hazard Recognition What does the blue part of the NFPA diamond signify?

20 19 Exposure Management - Chemical Routes of Entry  Inhalation  Absorption  Injection  Ingestion

21 20 A common route of chemical exposure is ingestion due to contaminated food or hands. Chemical Routes of Entry

22 21 Chemical Exposure – Health Effects  Acute effects – sudden, traumatic effects –Headaches, dizziness, burns from corrosive chemicals  Chronic effects – slow, gradual effects not rapidly perceived; poor or no warnings of exposure –Cancer, mutation, reproductive effects

23 22 Chemical Exposure - Exposure Limits  Risk = Exposure x Hazard –Toxic effects can be minimized by keeping exposures to a minimum.  Acceptable limits of exposure

24 23 Question Eating or drinking in a laboratory is strictly prohibited but acceptable in other areas where toxic/harmful chemicals are stored? FALSE

25 24 Exposure Management Hierarchy of control measures to minimize risk. Reduce time or amount of exposure, or alter nature of exposure. –Engineering controls –Administrative controls –Personal protective equipment (PPE)

26 25 Engineering Controls - Chemical Fume hoods Reduce exposure to airborne hazards. Ensure that your fume hood is:  Free of clutter  lfm  ‘Kim-wipe test’  Not open more than 12”

27 26 Chemical Fume hoods

28 27 Engineering Controls – Chemical Fume Hoods

29 28 Alter work practices:  Chemical substitution  Proper storage and segregation of hazardous materials  Proper housekeeping practice  Prudent inventory and purchase order management  Appropriate training and Right to Know information (such as MSDS) Exposure Management - Administrative Controls

30 29 Administrative Controls – Chemical Substitution Less hazardous alternatives  Citrosolv v. xylene  Enzymatic detergents v. chromic/sulfuric acid-based glass cleaners  SYBR Safe v. ethidium bromide

31 30 Administrative Controls – Chemical Substitution Mercury is a TOXIC metal. Clean-up is time and resource-intensive.

32 31 Administrative Controls - Chemical Storage Proper chemical storage reduces exposure risk.  Segregation –Hazard Class –Incompatibles –deep spill bins or separate cabinets  Labeling –All containers, including reaction vessels.

33 32 Administrative Controls - Chemical Storage Consider the following:  Compatibility  container and cabinet with chemicals  Proximity  chemicals, incompatible materials, heat, or open flame

34 33 What is wrong with this?

35 34 What is wrong with this?

36 35 Administrative Controls – Chemical Storage (Flammables)  Allowable limit of flammable materials.  Determined by construction materials and presence of sprinklers. –4 Lab types: I, II, III, IV –Flammable limits of 30, 25, 20, 15 gallons, respectively –Flammable waste materials count toward these limits

37 36 Administrative Controls – Chemical Storage (Flammables) Explosion-proof or intrinsically-safe refrigerators

38 37 Administrative Controls - Housekeeping 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. Poor housekeeping contributes to accidents and can hinder emergency response activities.

39 38 What is wrong with this?

40 39 What is wrong with this? Labeling Exposed Sharps Objects Open Bottle Open Sash Not Properly Managed

41 40 What is wrong with this? Poor housekeeping Excess chemical on the workbench

42 41 Administrative Controls - Inventory Management  Purchase order management  Smallest quantity sufficient for your work  Utilize ‘just in time’ delivery  Excess chemicals become Hazardous Waste  Updated chemical inventory  Dispose of all outdated or unused chemicals properly and promptly.

43 42 Exposure Management - Personal Protective Equipment  Safety glasses / goggles  Protective gloves  Aprons / lab coats

44 43 Personal Protective Equipment - Eye Protection Determined by risk factors  Safety glasses provide basic protection  must be worn when handling hazardous materials.  Safety goggles  splash hazards or highly corrosive materials  Laser goggles  wavelength-specific protection, with opaque non-lens components to protect the face.

45 44 Personal Protective Equipment - Hand Protection No one glove protects against all chemicals. Consult manufacturers’ guides Never re-use Change frequently contaminated or torn

46 45 Personal Protective Equipment - Hand Protection DO NOT TOUCH DOOR KNOBS OR ELEVATOR BUTTONS

47 46 Personal 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 contaminated  Keep coat buttoned to prevent entanglement in moving equipment.

48 47 What do you wear when you work in the lab?

49 48 Test weekly and keep a log. Don’t wait for an emergency! Safety Equipment
