23. Work Area Chemical Inventory (WACI) • Each work area will maintain an inventory list (WACI) of all chemicals present in the work area regardless of quantity • WACIs will be updated by the designated person annually and when new chemicals are added • WACIs will be provided to the Science Safety Coordinator annually and when updated

24. The WACI contains this information: • name and phone number of the person responsible for the work area and the name and signature of the person responsible for compiling the inventory • area name • location of the hazardous chemicals (building and room) • chemical name or the common name of the product and its ingredients • CAS numbers • container types • hazards associated with the chemical • maximum quantity that would be on hand at any time

25. Categories of Hazardous Chemicals • physical hazards - produce dangerous situations such as fires and explosions • health hazards - harm your body from the inside

26. Types of physical hazards: • combustible liquids • compressed gases • explosives • flammables • organic peroxides

27. Types of health hazards: • carcinogens • toxins • irritants • sensitizers • target organ effects Health hazards can have either acute (immediate) or chronic effects (occurring over a period of time).

28. Health hazards can enter your body through these routes: • absorption through skin or mucous membranes • ingestion by eating or drinking • inhaling / breathing in • puncture / injection

29. Evaluating and Controlling the Risk of Chemical Exposures • The chemicals we use have been tested (on animals) to establish estimates of how much of the chemical we can be exposed to OR how long we can be exposed to it before it has deleterious effects on us. • There are many terms used to describe these limits: TLV, PEL, TWA, STEL, and ceiling limits

30. Threshold limit value (TLV) • is the airborne concentration limit of a substance under which nearly all workers may be repeatedly exposed without adverse effect.

31. Permissible Exposure Limit (PEL) • is the maximum amount or concentration of a chemical that a worker can be exposed to. • PELs are measured in different ways: • 1. Ceiling limits are amounts or concentrations of a chemical that should never be exceeded even for very brief periods of time. • 2. A time weighted average (TWA) is the upper limit of exposure for a normal 8-hour work day. • 3. A short term exposure limit (STEL) is the concentration of a chemical that a worker can be exposed to for a short period of time without suffering irritation, chronic or irreversible tissue damage.

32. Guidelines for Labeling Hazardous Chemicals • 1. Primary container labels should contain: • identity of chemicals • physical and health hazards, including target organs • manufacturer’s name and address • 2. Secondary container labels must contain all of the • above except the manufacturer’s information. • 3. Replace labels if they don’t meet standards or are illegible. • 4. NEVER have any unlabeled, unattended containers in your work area.

33. Container Label Chemical name Hazard warnings Manufacturer

34. HAZCOM Labeling and Marking Systems • NFPA Diamonds • HMIS Labels

35. NFPA Diamonds • color coded, numerical rating system • located near main entrances, fire alarm panels, on outside entrance doors or cabinets • provide at-a-glance hazard information

36. Color Coding for NFPA Labels Red = Flammability Blue = Health/Toxicity Yellow = reactivity/stability White = special hazard information (NFPA)

37. Number Coding for NFPA Labels 4= Deadly Hazard 3= Severe Hazard 2= Moderate Hazard 1= Slight Hazard 0= No Hazard

38. HMIS Labels • designed to go on individual containers of products that don’t have manufacturer’s labels • same color code/numerical rating system as the NFPA diamonds with one exception • white = personal protective equipment or special protection information

39. Storing Chemicals Safely • all chemicals are stored according to hazard categories • incompatible chemicals are stored separately This is an example ofimproperly stored chemicals!

40. Personal Protective Equipment (PPE) The most important thing to remember about PPE is that it only protects you if you wear it!

41. Instructors must: • Wear the required PPE for the lab activity • Ensure that students wear the required PPE • Ensure that the PPE is worn by all students during the entire lab activity

42. PPE: Conditions Requiring Safety Eyewear • Eye protection must be worn when any of these is present: • chemicals • physical hazards • biohazards

43. PPE: Types of Safety Eyewear • There are two categories of safety eyewear: • Safety glasses – must have permanently attached side shields. • Goggles • Both types must meet the Z87 standard.

44. PPE: Choosing Safety Eyewear • Goggles provide the best all around protection. • If it is necessary to wear contact lenses in the lab, wear protective goggles rather than safety glasses. • Regular eyeglasses do not provide adequate protection when working with chemical or physical hazards

45. PPE: Choosing Gloves • any glove can be permeated by chemicals • nitrile gloves are more resistant to most chemicals than latex gloves • special gloves must be worn when handling materials that are hot, very cold, or sharp

46. PPE: Using and Changing Gloves • check gloves for cracks, tears and holes before use • to remove gloves: • grasp outside of one glove and pull it off • hold that glove with your gloved hand • insert your fingers under the cuff of the other glove • turn that glove inside out over the first glove

47. PPE: Other Protective Clothing • Lab coat: primary purpose is to protect against splashes and spills; they should be non-flammable and easily removed. • Rubber-coated apron: can be worn to protect against chemical splashes and be worn over a lab coat for additional protection. • Shoes: must fully cover the feet and should always be worn when chemicals are in use. • Hard hat: must be worn when there is a hazard from falling rock debris.

48. First Aid • Only minor injuries will be treated in the lab. • Do not give or recommend oral medications to students. • Note use of supplies on form in first aid kit.

49. Universal Precautions • are designed to prevent transmission of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and other blood borne pathogens • Assume that all body fluids are infectious. • Do not come into contact with anyone’s body fluids. • For cleanup of body fluids (blood, vomit), contact the campus administration office for assistance.
