OSHA LABORATORY STANDARD29 CFR 1910.1450
13
OSHA LABORATORY STANDARD

• The OSHA Occupational Exposures to Hazardous
  Chemicals in Laboratories Standard, or
  Laboratory Standard for short, requires employers
  to protect laboratory workers from health hazards
  associated with chemical exposure in the
  laboratory.

14
OSHA LABORATORY STANDARDCHEMICAL HYGIENE PLAN
(CHP)

• A requirement of the OSHA Lab Standard is for all
  employers that have laboratories to develop a
  written Chemical Hygiene Plan (CHP).
• Tulanes CHP is located in the Laboratory Safety
  section of the OEHS Policies Procedures Manual
  which can be found at the OEHS website,
  www.som.tulane.edu/oehs.

15
OSHA LABORATORY STANDARDCHEMICAL HYGIENE PLAN
(CHP)

• Tulanes CHP is a generic plan covering the many
  different types of laboratories at Tulane.
• It is to be supplemented by annually updated
  Standard Operating Procedures (SOPs) developed by
  laboratory supervisors/principal investigators
  discussing safety practices and procedures
  specific to the laboratory.

16
OSHA LABORATORY STANDARDCHEMICAL HYGIENE OFFICER
(CHO)

• The Lab Standard also requires each employer with
  laboratories to appoint a Chemical Hygiene
  Officer.
• The certified CHO for Tulane University is Pam
  Fatland of OEHS.

17
OSHA HAZARD COMMUNICATION (HAZCOM) STANDARD29
CFR 1910.1200
18
OSHA HAZARD COMMUNICATION STANDARD

• States You Have a Right to Know about Chemical
  Hazards in the Workplace and How to Protect
  Yourself
• Tulane has a Written Hazard Communication Plan
  located in the OEHS Policies and Procedures
  Manual (see the OEHS website www.som.tulane.edu/oe
  hs)
• A Supervisors Guide to the OSHA Hazard
  Communication (HAZCOM) Standard is available on
  the OEHS Website under the Chemical Safety Link

19
OSHA HAZARD COMMUNICATION STANDARD

• Under the OSHA HAZCOM standard, manufacturers of
  chemicals are required to evaluate the hazards of
  the chemicals they produce and transmit that
  information to customers on labels and Material
  Safety Data Sheets (MSDSs)

20
Become Familiar with Chemicals inYour Laboratory

• Chemical Inventory
• Container Labels
• Laboratory Door Signs
• Material Safety Data Sheets
• Reference Materials
• Training

21
PURPOSE OF UPDATING CHEMICAL INVENTORY

• To verify that you have Material Safety Data
  Sheets (MSDSs) you need in the work area and that
  OEHS library of MSDSs is complete
• Emergency Responders need inventory for
  emergencies, such as fires and spills, and for
  planning purposes
• To perform a hazard evaluation of the area,
  obtain appropriate PPE, verify proper storage and
  that containers are in good condition and not
  expired

22
PURPOSE OF UPDATING CHEMICAL INVENTORY

• Tulane is required to report inventory to local,
  state, and federal agencies such as the EPA, the
  State Police, and the Fire Department
• Fees based on the inventory must be paid to
  regulatory agencies (Example City of New Orleans
  Hazardous Materials Tax which helps to support
  the Fire Depts HAZMAT unit)

23
CHEMICAL LABELS Required Information

• Full Chemical Name
• Physical and Health Hazards (Flammable,
  Corrosive, Toxic)
• Manufacturer Name/Address/Phone Number (on
  incoming containers)

24
CHEMICAL LABELS Required Information

• Labels are required on all incoming containers,
  all transfer containers that will be left for a
  period of time, and on all containers that will
  be used by more than one person
• You can label an entire shelf instead of each
  individual container if all containers on the
  shelf contain the same thing (Ex. specimen
  containers of ethanol)
• Labels must be legible, in English with the full
  name of the chemical spelled out (no symbols or
  abbreviations)

25
CHEMICAL LABELS Required Information

• The purpose of labeling is to identify the
  material and to become aware of the hazards and
  the methods of protection
• Sometimes OSHA requires special wording to appear
  on the label of certain chemicals or at the
  entrance to a regulated area (Ex. Formaldehyde
  containers must say Irritant and Potential
  Cancer Hazard)

26
More Chemical Label InformationSometimes labels
contain other information that serve to enhance
the hazard warnings and identify means of
protection

• Signal Word (e.g., Danger, Warning, Caution)
• First Aid Procedures
• Handling Storage (e.g., Avoid contact with
  Acids)
• Special Instructions (e.g., Keep out of reach of
  children, Use with adequate ventilation)

27
Chemical Labeling SystemsOptional information
which may be found on a container label

• The National Fire Protection Association (NFPA)
  uses a color-coded diamond with a numerical
  rating system to identify the degree of health
  (blue), fire (red), or reactivity (yellow)
  hazards associated with a chemical in a fire
  situation. A zero means minimal hazards whereas
  a four indicates severe hazards.

28
Chemical Labeling SystemsOptional information
which may be found on a container label

• The National Paint and Coatings Association uses
  the Hazardous Materials Identification System
  (HMIS), a similar system of labeling which rates
  chemicals from zero to four on their health
  (blue), flammability (red), reactivity (yellow),
  and also gives personal protective equipment
  designations.

29
Improper Labeling
30
Improper Labeling - Abbreviations
31
LABORATORY DOOR SIGNSSignage for laboratory
doors stating the hazards found in the lab and
emergency contact information are available from
OEHS

• Door sign request forms available on OEHS website
  www.som.tulane.edu/oehs under the Chemical Safety
  link form can also be used for updates of
  current signs
• Signs contain stickers relating to hazards found
  in that laboratory (Example Flammable,
  Corrosive, Water Reactive)
• Signs also contain authorized admittance/emergency
  contact information which should be used before
  entering a lab or during an emergency to contact
  appropriate personnel
• Copies of signage forms are kept in OEHS for
  emergency response purposes

protection, skin protection such as gloves or
aprons, or face and eye protection such as face
shields and goggles.

• INHALATION Nose
• INGESTION Mouth
• SKIN CONTACT Skin, Eyes
• INJECTION Skin (subcutaneous vs. dermal)

38
MATERIAL SAFETY DATA SHEETS (MSDSs)

• MSDSs are documents that inform you of the
  hazards associated with a chemical and how to
  protect yourself from those hazards
• MSDSs must be readily accessible to employees in
  the work area where the chemicals are used
• Each company publishes its own MSDSs with their
  address and emergency contact information. Thus
  if you have a chemical such as acetone from two
  different manufacturers, you will need an MSDS
  from each company

39
MATERIAL SAFETY DATA SHEETS (MSDSs) (The
following are types of information that can be
found on an MSDS)

• Identity
• Ingredients
• Physical Properties
• Hazards
• Physical
• Health

• Precautions
• Storage
• Control Measures
• Disposal
• Spills
• Personal Protective Equipment (PPE)

40
MATERIAL SAFETY DATA SHEETS - ACQUISITION

• Manufacturers are required to ship MSDSs to
  Tulane with the first shipment of a chemical
• OEHS maintains a hard-copy library of all MSDSs
  received from the manufacturers and all chemicals
  listed on the inventories that are submitted.
  The OEHS library of MSDSs is kept at the OEHS
  office downtown
• MSDSs are also available on the OEHS website
  www.som.tulane.edu/oehs under the MSDS link
• The OEHS website/MSDS link also contains FAX
  numbers for common chemical manufacturers
• Contact OEHS if you have trouble finding an MSDS
  that you need

met

• All employees must be trained on how to obtain
  MSDSs
• You must be able to print MSDSs
• You must have an alternative to obtaining MSDSs
  in the event of power loss or other emergency
  (Contact OEHS Library of MSDSs)

43
OSHA LABORATORY STANDARDTRAINING INFORMATION
TOPICSThe OSHA Lab Standard States that you must
be familiar with the following

• Methods to detect hazardous chemicals in the work
  area
• Signs and symptoms of exposure to chemicals
• Methods to reduce exposure
• Physical health hazards of chemicals used in
  the work area
• PPE and emergency procedures
• CHP/SOPs reference materials

44
OSHA LABORATORY STANDARDDetecting Hazardous
Chemicals

• Permissible Exposure Limits
• Signs symptoms of exposure to chemicals
• Odors/Leaks/Spills
• Monitoring exposure

45
OSHA LABORATORY STANDARDEXPOSURE CONTROLThere
are three main ways to control exposure to
chemicals

• Engineering Controls (usually consists of
  ventilation, safety showers/eyewash units, etc.)
• Work Practices (handling, storage, housekeeping,
  etc.)
• Personal Protective Equipment (gloves, eye/face
  protection, etc.)

46
CHEMICAL FUME HOODS

• Designed to protect the worker from toxic or
  hazardous chemicals
• 100 of air exhausted to outside
• No recirculation of air
• Baffles in back should adjust for work with
  chemicals of different volatilities and vapor
  densities

47
CHEMICAL FUME HOODS

• All chemical fume hoods at Tulane must have an
  alarm or airflow indicator device on them to show
  that they are operating properly
• Most chemical fume hoods should have a face
  velocity in the range of 80-100 fpm

48
Fume Hood Alarm
49
CHEMICAL FUME HOODS

• Do not assume that your fume hood is operating
  properly. Check the alarm indicator. At the
  very least, use a piece of tissue paper and make
  sure it is drawn inward. IF NOT OPERATING
  PROPERLY, DISCONTINUE WORK WITH HAZARDOUS OR
  TOXIC CHEMICALS!

50
FUME HOOD SAFETY TIPS

• Keep the sash as low as possible
• Work at least 6 inches inside hood
• Keep work surface clear of unnecessary items
• Keep baffles clear of obstructions elevate
  large equipment off work surface

51
FUME HOOD SAFETY TIPS

• Avoid rapid movement into and in front of hood
• Pedestrian traffic in front of hood creates
  turbulence and can pull vapors out of hood and
  into operators breathing zone

52
FUME HOOD SAFETY TIPS

• Keep the amount of material in a hood to a
  minimum excessive clutter increases turbulence
  and reduces hood efficiency
• An airfoil helps to minimize undesirable
  turbulence when air entering the hood impacts the
  front edge of the floor of the hood be sure
  airfoil is installed and side panels are in place

53
FUME HOOD SAFETY TIPS

• Secure loose lightweight objects such as paper
  towels
• Run water in hood drains often to reduce odors
  that may develop in p-trap
• Ensure adequate illumination in hood
• Be aware that opening and closing lab doors can
  affect hood performance

54
FUME HOOD SAFETY TIPS

• Keep the sash clean and unobstructed
• Place cords and hoses under the airfoil so sash
  can be kept closed
• Practice good housekeeping
• Clean chemical residues and spills from interior
  hood surfaces

55
FUME HOOD SAFETY TIPS

• Do not place absorbent paper under heating
  appliances
• Do not place incompatible chemicals together
• Remember the emptier the hood, the better air
  currents can flow through it! Do not use hood as
  storage cabinet.

56
CANOPY VENTILATION

• May be 100 Exhausted to outside, but not
  recommended for chemical use
• Draws fumes past workers breathing zone
• Best used for heat removal such as in a kitchen

57
OSHA LABORATORY STANDARDEXPOSURE CONTROL
EYEWASHES/SHOWERS

• Eyewash fountains are required in work areas
  where formaldehyde, irritants, or corrosive
  chemicals are used and there is the potential for
  a splash to the eye.
• Eyewashes must be tested weekly by the laboratory
  personnel. Showers must be tested at least
  annually by Facilities Services.

58
OSHA LABORATORY STANDARDEXPOSURE CONTROL
EYEWASHES/SHOWERS

• Emergency showers/eyewashes must be readily
  accessible, clear of obstructions, and clearly
  labeled.

59
OSHA LABORATORY STANDARDEXPOSURE CONTROL WORK

• Use in a designated area
• Use containment devices such as a fume hood
• Dispose of waste properly
• Decontaminate work area
• Have an emergency plan

66
OSHA LABORATORY STANDARDEXPOSURE CONTROL
PERSONAL PROTECTIVE EQUIPMENT (PPE)

• PPE is used as a final alternative in the event
  that engineering controls and work practices do
  not adequately prevent exposure to chemicals.
• PPE must be adequate for the substance being
  handled and must be available in different
  sizes/styles (i.e., powdered unpowdered gloves).

67
OSHA LABORATORY STANDARDEXPOSURE CONTROL
PERSONAL PROTECTIVE EQUIPMENT

• PPE must be inspected to make sure it is in good
  condition.
• Personnel must be trained on PPE, how and when to
  use it, how to maintain and store it, etc.

68
OSHA LABORATORY STANDARDEXPOSURE CONTROL
PERSONAL PROTECTIVE EQUIPMENT (PPE)

• A Dartmouth researcher got one drop of
  dimethylmercury on her latex glove and died from
  the exposure. Latex was not appropriate for
  protection for work with dimethylmercury.
• Latex or PVC gloves are not suitable for direct
  contact with corrosive or highly toxic chemicals.
  
• Glove permeability charts are available from
  glove manufacturers to help you decide which type
  of glove is appropriate for use with different
  chemicals. Contact OEHS for more information or
  if you have questions.

69
OSHA LABORATORY STANDARDEXPOSURE CONTROL
PERSONAL PROTECTIVE EQUIPMENT (PPE)

• If gloves are reusable, clean and inspect them
  after use. Store them in a manner in which they
  will not become torn or damaged.
• If gloves are disposable, or if they are torn or
  in poor condition, dispose of them in appropriate
  trash container. Do not throw on floor or leave
  dirty gloves on counters.

70
OSHA LABORATORY STANDARDEXPOSURE CONTROL
PERSONAL PROTECTIVE EQUIPMENT

• Respirators require a medical evaluation and
  annual fit-testing.
• Respirators should only be used if engineering
  and work practice controls cannot adequately
  control a chemical exposure.
• Contact OEHS immediately if you feel a respirator
  may be needed in your area.

71
OSHA LABORATORY STANDARDEXPOSURE CONTROL
PERSONAL PROTECTIVE EQUIPMENT

• Respirators require adherence to a strict
  respiratory protection program.
• When requested, OEHS will monitor area to help
  determine if respirators may be required. In
  most cases, exposure to chemicals can be
  controlled by alternative methods.

72
OSHA LABORATORY STANDARDEXPOSURE CONTROL
PERSONAL PROTECTIVE EQUIPMENT (PPE)

• Regular prescription eyeglasses do not take the
  place of safety glasses or goggles.
• The American Chemical Society has taken the
  position that contact lenses may be worn in the
  laboratory as long as appropriate eye protection
  such as safety glasses or goggles, as required of
  other workers in the laboratory, is also worn.

73
OSHA LABORATORY STANDARDEXPOSURE CONTROL
PERSONAL PROTECTIVE EQUIPMENT

• Safety glasses and goggles should be stored in a
  manner in which they will not become dirty or
  scratched, such as in a drawer or cabinet, or in
  a plastic bag. They should not be left on the
  counter or hung by their straps.

74
OSHA LABORATORY STANDARDEXPOSURE CONTROL
PERSONAL PROTECTIVE EQUIPMENT (PPE)

• In addition to wearing suitable PPE, a laboratory
  worker must also dress appropriately for their
  work. For example, sandals/flip-flops, shorts,
  and tops with exposed midriffs are inappropriate
  attire for laboratory work with hazardous
  materials.

75
OSHA LABORATORY STANDARDEMERGENCY PROCEDURES

• In the event of an emergency
• Evacuate the area
• Contact Public Safety and OEHS immediately
• Be familiar with your Emergency Action Plan (EAP)
  evacuation policy, procedures, and escape
  routes see your Departmental Safety
  Representative for more information

76
OSHA LABORATORY STANDARDEMERGENCY PROCEDURES
FIRE SUPPRESSION

• Before using a fire extinguisher
• Make sure you have an unobstructed escape route
  at your back
• Fire should be small, confined, and not spreading
  (e.g., trash can fire)
• Know that the extinguisher is the right type for
  the job
• Know how to use an extinguisher

77
OSHA LABORATORY STANDARDEMERGENCY PROCEDURES
FIRE SUPPRESSION

• To use a portable fire extinguisher, remember
  PASS
• Pull the pin
• Aim the nozzle at the base of the fire
• Squeeze the handles
• Sweep from side to side

78

• E EVALUATE the situation
• S SECURE THE AREA Remove occupants
• C CLOSE THE DOORS to contain the fire
• A ACTIVATE THE FIRE ALARM use the nearest
  pull station
• P PHONE THE DESIGNATED EMERGENCY NUMBER
• Uptown Campus dial 865-5200 or X5200
• E EXTINGUISH THE FIRE using a portable fire
  extinguisher, if you determine it is safe to do
  so (fire is small and not spreading, fire
  doesnt come between you and the exit, etc.)

79
BUILDING BLOCKS OF LABORATORY SAFETY

• Make safety a top priority
• Make information available and accessible (MSDSs,
  safety literature, etc.)
• Use equipment appropriate for the task
• Be watchful during experiments be ready for
  unexpected events
• Substitute less hazardous substances when
  possible, or use other methods such as robotics

80
BUILDING BLOCKS OF LABORATORY SAFETY

• Avoid close calls and doing something just this
  once
• Do not procrastinate (get equipment repaired, buy
  needed PPE, etc.)

81
HAZARDOUS WASTE MANAGEMENT
82
What Is A Hazardous Waste?

• Any hazardous substance that meets the EPA
  classifications of the following
• Flammable
• Corrosive
• Reactive
• Toxic

• Items received with hazardous shipping labels
  will most likely become hazardous waste

83
What Is A Hazardous Waste?

• Check the Material Safety Data Sheet to help
  determine if your waste chemical is a hazardous
  waste

84
What Is Hazardous Waste?
Any of these keywords usually indicate the waste
materials will be hazardous waste

• Flammable
• Inflammable
• Flashpoint (lt140 F)
• Corrosive, Acid, Basic, Caustic
• Explosive

• Stench Agent
• Oxidizer
• Water or air Reactive, Pyrophoric, Peroxide
  Former
• Poison

85
Empty Containers

• Empty containers are not considered as hazardous
  waste. They can be tossed in the solid waste
  disposal receptacle after the label has been
  removed or defaced.

86
Hazardous waste disposal rules

• 1. Minimize
• 2. Containerize
• 3. Label
• 4. Store less than 30 days

87
Rule 1 - Minimize

• By law, a Waste minimization program is
  required. Among ways this goal is accomplished
  is by
• Source reduction (ordering less)
• Surplus chemical redistribution
• Labeling all containers (disposal of unknowns is
  expensive)
• Redistilling solvents
• Using mercury-free instruments
• Substituting hazardous chemicals with
  non-hazardous chemicals
• Using secondary containment

88
How you can help minimize costs

• DONT MIX WASTES
• Only compatible waste solvents should be mixed
  together in the appropriate waste container
• Dont mix acids and flammable materials together
• Dont mix biological and chemical waste
• Dont mix radioactive and chemical waste
• These practices can reduce the cost of disposing
  various types of hazardous waste.

89
How you can help to minimize waste

• Neutralizing Acids
• Acidic waste can be sewer disposed after
  neutralization, but we need to know what else may
  be in it -- i.e. heavy metals (like Mercury,
  Lead, Chromium, Cadmium, Selenium or Barium),
  flammable liquids, and poisons. Acids with other
  regulated hazardous ingredients CAN NOT be sewer
  disposed.

90
Rule 2 - Containerize

• Only use containers that are compatible to the
  hazardous waste.
• Make sure that all containers remain closed
  except when hazardous waste is being added.
  Remove funnels and be sure to cap containers
  after adding waste.

91
Waste Containers

• Chemical waste generated at each generators work
  site should be kept in a rigid, compatible
  container until it is shipped for disposal.
• The chemical waste is collected by lab personnel
  and should not be stored for more than one month.

Be sure waste chemicals are compatible with the
container.
92
Keep waste containers closed

• Keep waste containers closed except when adding
  waste.

93
Containerize

• Chemical waste in general, and hazardous waste in
  particular, must be stored in a sturdy container,
  free of leaks.
• OEHS will not accept open containers for
  hazardous waste disposal.

94
Secondary Containment
Secondary Containment

• To contain hazardous waste if the container
  leaks, the hazardous waste container should be
  kept in secondary containment such as a tray or
  tub.

95
Containers

• Cans of paint without lids, leaky ballasts,
  broken thermometers and chemically contaminated
  items must be overpacked into another container
  which is free of leaks so we can put it on a cart
  and roll the cart safely over campus sidewalks to
  the storage facility.

96
Rule 3 - Labeling Why you must label waste
containers

• Waste containers are required by law to be
  labeled
• So Environmental Health and Safety knows how to
  process the waste
• Because Environmental Health and Safety cannot
  pick up unknowns
• Because unknowns are very expensive to ship for
  disposal

97
When should you label your waste container?

• The DATE waste is first put into the container
  must be on the label along with the name of the
  chemical.
• As EACH NEW container of hazardous waste is
  filled, the name of that chemical must be
  placed on that container.

98
Labeling

• Please do not rely on the hazardous waste person
  picking up your waste to label your containers.
• Include anything unusual on the label, even if in
  small quantity (examples reactive and explosive
  chemicals, PCBs, dioxins, extremely toxic
  chemicals, etc.)

99
Hazardous Waste Labeling

• Do not use chemical symbols, abbreviations, or
  codes for waste identification
• In addition to the full chemical name, you must
  list the hazards associated with the waste, such
  as flammable, corrosive, etc.

• The words Hazardous Waste must appear on the
  label
• Hazardous waste labels are available through OEHS

100
Rule 4 Store Less Than 30 DaysCall 988-2865 to
request a waste pick-up
Please provide the following information

• your name
• your phone number or e-mail address
• location of the waste (building name room )
• whether you need any empty waste containers
