  12. Provided Information • Occupational Exposure to Hazardous Chemicals in Laboratories (OSHA Lab Standard, 29 CFR 1910.1450) • ECU Chemical Hygiene Plan • Permissible Exposure Limits for OSHA regulated substances, or recommended exposure levels for other hazardous chemicals where there is no applicable standard • Signs/Symptoms associated with exposures • Known Reference Materials on hazards, safe handling, storage and disposal Information located on container labels, SDS’s, EH&S website

  13. Types Of Hazards • CHEMICAL AND PHYSICAL HAZARDS – EH&S • RADIATION AND BIOLOGICAL SAFETY –Prospective Health • EMPLOYEE HEALTH –Prospective Health • ANIMAL HANDLING –Comparative Medicine

  14. Types Of Chemical Hazards Health Hazards Physical Hazards Explosive Flammable Gases Under Pressure Pyrophoric Self-Reactive Water Reactive Oxidizer Organic Peroxide Corrosive to Metals • Acute Toxicity • Carcinogenicity • Reproductive Toxicity • Skin Corrosion/Irritation • Respiratory or Skin Sensitization • Aspiration Toxicity • Target Organ Systemic Toxicity • Hazardous to Aquatic Environment

  15. 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

  16. Routes Of Exposure • INHALATION • ABSORPTION • INGESTION • INJECTION The most likely target depends upon the characteristics of the material being used.

  17. ROUTES OF EXPOSUREINHALATION • Primary Route of Entry • Airborne contaminants such as gases, vapors and particulate matter that enter directly into lungs. • Chemical fume hood is the primary control available. • Respiratory protection or specialized exhaust may be necessary where a fume hood cannot be used.

  18. ROUTES OF EXPOSUREABSORPTION • Can occur very quickly through cuts or abrasions on the skin. • Depending on the characteristics of the contaminant, absorption may occur through intact skin (example: phenol) • Mucous membranes and eye tissue are particularly vulnerable • Barrier protection (such as gloves) and personal hygiene are the primary control measures.

  19. ROUTES OF EXPOSUREINGESTION • Includes direct tasting of chemicals. • More often occurs when contaminated items are placed in the mouth. • Purpose for banning food, drink, tobacco, and cosmetics in the lab. • Personal hygiene, labeling and housekeeping are very important to ingestion hazard control.

  20. ROUTES OF EXPOSUREINJECTION • Includes all puncture wounds. • Examples: needle sticks, glass shards or capillary tubes puncturing skin • Difficult to protect against • Use carefully planned procedures and personal diligence, including needle blocks.

  21. Standard Operating Procedures • Personal Protection • Laboratory Practice • Personal Safety • Laboratory Controls • Lab Specific Information Should Be Identified in Lab Safety Plans Available on EH&S website

  22. 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

  23. Protective Clothing • Closed toed shoes of non-woven material with non-slip soles • Clothing that covers arms and legs, NO SHORTS • Lab coats with closed fasteners • Non-flammable, non-porous aprons when using corrosives • Remove before leaving the lab • Launder separately

  24. Gloves • Compatible with materials used • Remove gloves and wash hands before leaving • Inspect before use • Clean or discard immediately after use • Do not use latex gloves for chemical protection

  25. Respiratory Protection • Use approved through EH&S • Must be part of the ECU Respiratory Protection Program • Medical Clearance • Training • Annual Fit Test • Respirators returned to EH&S when project complete

  28. New Labels from Manufacturer • Labels are required to have: • Product Identifier • Supplier Information • Signal Words • Pictograms • Hazard Statement • Precautionary Statement

  29. New Labels from Manufacturer Signal Word • Used to indicate the relative severity of the hazard • Alert reader to a potential hazard on the label • “Danger”: more severe hazards • “Warning”: less severe hazards

  30. New Labels from Manufacturer Pictogram • Each pictogram consists of a symbol on a white background framed within a red border and represents a distinct hazard. • The pictogram on the label is determined by the chemical hazard classification. • Nine total pictograms. Eight mandatory pictograms are designated.

  31. HCS Pictograms and Hazards

  32. New Labels from Manufacturer Hazard Statement • Describes the nature and degree of the hazards of a chemical • Examples: • Fatal if swallowed (Signal Word: Danger) • Harmful if swallowed (Signal Word: Warning)

  33. New Labels from Manufacturer Precautionary Statement • Describes recommended measures to prevent and minimize adverse effects from exposure or improper handling and storage • Address the following areas: • Prevention • Response • Storage • Disposal • Examples: • Keep container tightly closed. • Keep away from heat/sparks/open flame.

  34. Chemical Labels • Maintain Labels on Incoming Containers • Replace Torn or Defaced Labels • Label Secondary Containers Immediately • Label Content for Secondary Containers • Name of Hazardous Chemical • Hazard Warning • Name of Responsible Party • Date of Preparation * Expiration date for peroxide formers
