    Introduction

    Regardless if you work at a biotechnology visitor or in an academic research lab, keeping a lab notebook is a requirement. The Nutrient and Drug Administration's (FDA) handbook states, "if it isn't written down, it wasn't done." The lab notebook is considered a legal document and can be used in court to settle patent disputes or to report a specialist's finding in paternity suits or criminal cases. Oft times, the lab notebook is used as a starting point for other scientists who work in the lab. Lab notebooks are always maintained for the following reasons:

    • To record the steps an individual has carried out and to certificate their observations
    • To establish ownership in case of a patent dispute or other legal bug
    • To establish guidelines used to evaluate the process in which a product was made and to evaluate the product itself
    • To follow the production of a production through the manufacturing procedure
    • To create a contract between a company and consumers and/or between a company and regulatory agencies
    • To demonstrate a procedure was done correctly
    • To develop, follow, and evaluate standard operating procedures (SOP)

    Without documentation, even quality work is worthless. In the upshot of an experiment declining, the documentation allows for a scientist to review their protocol and make adjustments for hereafter experiments. As stated above, in industry, lab notebooks are legal documents. They are used to determine product quality, patent rights, and liability. Notebooks are e'er treated every bit if they volition exist used in court because the consequences of not doing so could be devastating to a company.

    Part I: Setting Upwards a Legal Scientific Notebook

    A notebook should contain what equipment and materials were used and what steps were followed to show that the equipment and materials were validated before use. In case of an audit past regime regulatory agencies, a company must exist able to produce documentation that proves that they are following Good Manufacturing Practices (GMPs). If they find that a notebook was missing information or was non legible, so the company may be fined or held liable for amercement in a product lawsuit. The importance of a well-kept notebook cannot exist emphasized enough.

    Guidelines for Setting Up a Legal Scientific Notebook

    *For the purpose of this grade, pages suitable for a lab notebook are included in the appendix. Your instructor may directly yous to print a specific number of pages and demark them with staples along the long left edge to serve as a low-cost substitute for an official bound notebook.

    1. Obtain a spring notebook, such equally a composition book. Spiral notebooks are non adequate.
    2. Use merely blue or black pen to make entries. NO PENCIL Allowed.
    3. Label the outside of your notebook with the information:
      sticker on front of composition style lab book
      Figure 1. Lab notebook comprehend setup: Row one: Name, Row ii: Intro to Biotech Lab, Row 3: Professor'due south Name, Row 4: Semester/Yr.
    4. Make pages i-4 the Tabular array of Contents. Write "Table of Contents" at the tiptop of each of these pages. Record the title of each lab or entry and the page number for each.
    5. Each page in the notebook must be numbered. Number each page of the notebook in the upper corner with the first page of the notebook being "page one." The back of the first page will be "folio 2" and so on.
    6. Tape the date of each entry at the top of each folio.
    7. Sign and date the bottom of each folio.
    8. For each experiment (or activity) that yous perform, you should include the purpose for the experiment, the materials and methods you use, any data tables, figures or graphs properly labeled with a championship, and a conclusion.
    9. Do not erase errors. Merely draw a single line through an erroneous entry, then add your initials. Enter the correct entry nearby.
    10. Never get out bare spaces. Draw a diagonal line through all open up or blank space.
    11. If an entry continues on a different page, include "become to page ____" on the bottom correct mitt of the folio to let the reader know where the balance of the information is located.
    12. Graphs and other modest sheets of paper can exist pasted into the notebook using a gum stick.
    13. Always include enough details for someone else to successfully indistinguishable the work y'all take recorded.
    14. Characterization all figures, tables and calculations. Figures should be labeled on the bottom left and tables are labeled on the pinnacle left.
    15. Never remove pages from your notebook.

    Activity: Analysis of Sample Lab Notebook Entries

    1. Using bluish or black pen complete steps A-Eastward of the "guidelines for setting up a legal scientific notebook."
    2. Enter a title in your lab notebook folio (and in Table of Contents) equally "Assay of Sample Lab Notebook Entries."
    3. Label the height of folio 5 Lab A: Analysis of Sample Lab Notebook Entries.
    4. Each student should obtain a copy of the "Sample student notebook entries."
    5. Review each of the iii samples by yourself. You may choose to apply the notebook scoring rubric provided in the appendix of this transmission. Once you have reviewed the entries you tin can discuss your opinions with your grouping members. Make a list of what the student did well and what the pupil could have improved upon.
    6. Draw three tables into your notebook, ane for each student entry you volition exist evaluating.

    Score: ____ / 10 pt

    Table 1. Review of Sample Lab Notebook: Entry #ane

    Hazard Communication Standard (HCS)

    A quick assessment of a chemic's hazards is visible on its container on a Hazard Communication Standard (HCS) characterization. HCS labeling does not supersede the more detailed Safety Data Sheet (SDS) but rather gives the following information in brief:

    • Name, Address, and Phone Number of Responsible Party (i.e., the manufacturer or distributor)
    • Chemical Identification - chemic name and code or batch number that matches the information constitute in Section ane of the chemic'southward SDS
    • Point Word - "DANGER" for more severe hazards or "WARNING" for less severe hazards
    • Hazard Statements - a cursory clarification of the hazard(due south)
    • Precautionary Statements (optional) - prevention, response, storage, and disposal
    • Hazard Category Numbers 1-4 (optional) - "1" for the nearly severe hazard to "iv" for the least severe
    • Pictograms

    Pictograms are red-bordered, diamond shapes that frame a black graphic on a white background, and these symbols depict the blazon of hazard(southward). HCS labels are required by the Occupation Safety and Wellness Administration (OSHA) and are standardized, having been adopted from the Globally Harmonized Organization of Classification and Labeling of Chemicals (GHS) fix by the United Nations.

    3. Write down the label's bespeak word and any chance statements, and annotate on the characteristics and hazards of the 2 items.

    Chemical Hazards and Waste material Disposal

    Laboratory waste material must be disposed of safely and appropriately. Labs must be aware of the school, land and federal guidelines for waste disposal. Many chemicals can NOT exist poured downward the sink. Be sure you know which chemicals are hazardous, require special storage and must exist placed into properly labeled waste containers kept in smoke hoods until sent to the proper hazardous waste disposal. Know which materials are considered biohazards and the proper area or container to place them then they tin be autoclaved.

    Table 4. Medical and Biohazardous Waste product Treatment and Disposal Chart, U. California

    Blazon of Waste

    Definition

    Required Treatment

    Chemical Waste matter

    Any solid, liquid, or gaseous material generated in the laboratory that poses a danger to man wellness or the surroundings.

    This will vary depending on the chemical. The establishment you lot are in volition have specific requirements to encounter regulatory code. The aim is to reduce hazards and minimize environmental impact. Follow your teacher'southward directions.

    Solid Biohazardous Waste

    Materials such as pipettes, petri dishes, or other culture flasks disposable or glass that practise not contain liquid but were in contact with cultures of cells or human or animal-derived materials.

    Disposable waste is placed in red biohazard bags. Treat and supercede bags when they are halfway full. Reusable glass materials must be placed in autoclavable trays. To treat waste, the autoclave must be properly loaded and set for a minimum temperature of 121°C (250°F) for hr at fifteen psi. Autoclave tape must exist placed on the bag or tray to indicate information technology has passed through the cycle. Material should be autoclaved as shortly as possible, simply at a maximum of vii days afterwards information technology is generated

    Liquid Biohazardous Waste matter

    Broth cultures or prison cell culture media or contaminated liquid media.

    Decontaminate using x% bleach solution for a minimum ii hours contact time. Dispose down the bleed with h2o.

    Alternatively, racks of used culture tubes tin can be autoclaved using the aforementioned temperature and fourth dimension indicated above simply set for a slow frazzle liquid setting. Employ autoclave tape equally above. Treat waste product equally presently as possible but not longer than 7 days post generation.

    Sharps Waste

    Whatsoever object that is capable of piercing or damaging human being pare that is contaminated with chemic, or biohazardous waste e.g., scalpels, blades, needles, broken glass, etc.

    Place in the marked sharps container.

    Remember that broken glass that is not contaminated will accept a separate disposal container within the laboratory.

    D. National Fire Protection Association (NFPA) Hazard Rating System

    The National Fire Protection Association (NFPA) Hazard Rating System was designed for emergency workers such every bit fire responders to exist able to swiftly get basic data about the hazards of a chemical from a simple label. The diamond-shaped label is divided into four color-coded squares, and inside each square is printed a ratings lawmaking or number from 0-4, with "0" as the least astringent risk to "four" as the most severe.

    Inside the red square, the number indicates the flammability rating; blue indicates the wellness hazard rating; yellow indicates the chemical'south instability; and the white foursquare indicates any special hazards.

    Procedure

    1. Walk around the room and find a label with the NFPA safety diamond. Read the explanations in the table above. Write downwards the chemical proper noun and describe its NFPA diamond.
    2. Remember of a chemical used in a lab or observe a second container without an NFPA characterization already affixed and and so write down its name. Use an internet or in-class resource to draw that chemical's NFPA ratings.
    3. Compare the NFPA 704 characterization with OSHA'south Hazard Communication label from the previous activity. How are they the same? How do they differ? What are the pros and cons of each type of label?

    E. Condom Data Sheets (SDS)

    A Safety Data Sheet (previously chosen Fabric Prophylactic Information Sheet) for each chemic is required by the Occupational Prophylactic and Health Administration (OSHA). Sections 1-eight contain information about the identification, hazards, composition, rubber handling practices, and emergency control measures. Sections nine through eleven and 16 contain technical and scientific information, such as physical and chemical properties, stability and reactivity, toxicology, and exposure control.
