Training

• Chemical Hygiene Training
• Basic training provided by EHS
• OSHA Lab Standard Training
• Laboratory Specific Training
• Provided by lab supervisor
• Includes content of lab safety plan

3
Routes Of Exposure

• Inhalation
• Absorption
• Ingestion
• Injection

4
Effects Of Exposure

• ACUTE - direct threat that shows up almost
  immediately after exposure such as burns from
  contact with a corrosive chemical
• CHRONIC - usually result from repeated exposure
  that occurs over months or years and includes
  cancer and some allergic reactions

5
Protecting Yourself

• Take measures to protect yourself
• Laboratory Practice Standard Operating
  Procedures (SOP)
• Personal Safety
• Laboratory Controls
• Personal Protective Equipment (PPE)

6
PPE-Eye Protection

• All lab users, including visitors, must wear ANSI
  approved eye protection when potential exists for
  eye injury
• Contacts may be worn in the lab under appropriate
  eye protection
• Face shields and/or standing guards must be
  available for face or neck protection. Face
  shields do not replace the need for eye protection

7
PPE-Protective Clothing

• Close toed shoes of non-woven material with
  non-slip soles
• Some areas require steel toed shoes or boots
• Non-flammable, non-porous aprons
• when using corrosives
• Remove before leaving the lab
• Launder separately

8
PPE-Respiratory Protection

• Use approved through EHS
• Must be part of UA Respiratory Protection Program
  this includes
• Medical Clearance
• Training
• Annual Fit test

9
PPE-Gloves

• Be sure they are compatible
• with the chemicals involved
• Remove gloves and wash hands before leaving
• Inspect before use
• Clean or discard immediately after use

• Discard Chemicals Not Used in Past 2 Years or Not
  Identified for Future Procedures
• Store Chemicals in Compatible Groups

• Separate Groups with Barriers
• Flammables Cabinets gt10 Gal.
• Closed Cabinets or ¾ Lip
• Corrosives Below Eye Level
• Inspect Containers and Labels Weekly
• Clean out old inventory only maintain active
  chemicals

14
Lab Practice-Housekeeping

• Close and Cap All Containers Not in Use
• Clean Drips and Spillage Off Of Container
  Exterior
• Maintain the Minimum on the Work Surface

• Maintain Clear Working Aisles
• Maintain Clear Access to Fire Extinguishers,
• Safety Showers and Eyewashes
• Label Doors that Are Blocked
• Keep Storage Out of Halls

15
Other Concerns-Compressed Gas Cylinders

• Installed and Leak Tested by Trained Personnel
• Secured in an Upright Position
• Capped When Not In Use
• Use Compatible Regulator and Auxiliary Equipment
• EHS has training for the use of gas cylinders

16
Safety EquipmentEyewash and Safety Showers

• All equipment must meet ANSI Requirements
• If used, Flush eyes with 15 Minutes of Clear,
  Running Water
• Operate Eyewash Weekly to maintain lines
• If Used Seek Medical Attention
• Tested by EHS annually
• Maintain Clear Access

17
Engineering ControlsChemical Fume Hood

• Use For All Operations Where Odoriferous,
  Volatile, Toxic or Harmful Release is Possible
• Assure Hood is Properly Functioning
• Work at least 6 inches into the hood
• Elevate Large Apparatus 2 inches
• Maintain Sash Height At or Below Posted Level
• Do Not Use the Hood for Storage

18
What About Waste?

• Waste is a Chemical listed by the Environmental
  Protection Agency as a Hazardous Waste
• A compound or solution that is
• - Corrosive
• - Toxic
• - Reactive
• - Flammable

19
Unwanted Chemicals

• The University of Alabama does not maintain
  waste in labs on campus
• We have unwanted chemicals
• Collect any chemicals ready for disposal, label
  with a completed Unwanted Chemical label, and
  submit pickup request through CEMS
• Labels and CEMS link on EHS website

20
Unwanted Chemical Containers

• Collect in clean chemical containers, compatible
  with collected material
• Containers must have a tight fitting cap that
  will not leak if tipped
• Keep container exterior free of damage or
  contamination
• Do not mix incompatible wastes

21
Unwanted Chemical Accumulation

• Waste must be properly segregated and stored
  according to compatibility
• Wastes must be stored with a tight fitting cap or
  lid and be free from leaks, damage or outside
  contaminants
• Kept in designated area preferably with
  secondary containment
• Every container must remain closed except when
  adding waste (in fume hood)
• When ready for pickup, submit pickup request
  through CEMS at www.bama.ua.edu/ehs

• NO chemicals are to be discharged into the sewer
  system without EHS approval

23
In Use or Waste Chemical Labeling

• All chemical containers must be properly labeled
  with name and hazards of chemical
• Unwanted chemical labels must be attached to
