PPE & Behavior
The standard for personal conduct in lab, which strictly bans horseplay, practical jokes, wandering around, or distracting others
What is acting responsibly at all times?
Solid chemicals, metals, matches, and filter paper must go here, whereas sinks are strictly reserved for water and designated solutions.
What are proper waste containers?
The immediate step a student must take the second they notice an unsafe condition, equipment defect, or any accident/injury.
What is notifying the instructor immediately?
This core rule states that a lit Bunsen burner or an active hot plate must never be left in this dangerous state.
What is unattended?
What you must do before touching any equipment upon entering the room, and what to do if you don't understand a procedure direction.
What is waiting for instruction and asking the teacher?
These two items must be worn any time chemicals, heat, or glassware are used, with no exceptions for contact lens wearers.
What are goggles and lab aprons?
The standard safety assumption you must make about all laboratory chemicals, requiring you to check bottle labels twice before using.
What is that they are considered dangerous?
The mandatory emergency phrase you must yell out immediately if you or your lab partner are hurt to instantly grab the teacher's attention.
What is "Code one, Code one"?
When heating a substance or boiling liquids inside a test tube, you must ensure the open end is never pointed here.
What is at yourself or anyone else?
The rule stating you must inspect items for chips, cracks, or dirt before use, and never use your bare hands to handle them if they break.
What is checking glassware and using a brush and dustpan for broken glass?
Before a lab starts, long hair must be tied back, dangling jewelry removed, and this type of footwear must cover the feet completely.
What are closed-toe shoes?
To prevent cross-contamination, you must never do this with unused chemicals, and you must hold containers away from your body when transferring.
What is returning them to their original containers?
The minimum duration of time required to flush your eyes or skin with running water if a chemical splash occurs.
What is 20 minutes?
Exercising extreme caution with gas flames, ensuring no unauthorized substances are placed into them, and never doing this to a container while heating.
What is looking directly into it?
Reading instructions carefully, operating volatile substances under a fume hood, and using this item under a pan to contain spills
What is a fume hood and handling flammable liquids over a pan?
Because of contamination risks, doing this is completely banned in the lab, and hands must be washed with soap and water after experiments
What is eating or drinking?
The proper way to transport materials securely, which strictly forbids using mouth suction to fill a pipette or removing chemicals from the lab
What is walking carefully and using a pipette pump/bulb?
During a fire drill, these three structural actions must be performed on your lab station setup before exiting the room.
What are closing containers, turning off gas valves, and turning off electrical equipment/fume hoods?
Because heated metals and glass stay hot for a very long time, you should use tongs or protective gloves, and never place hot apparatus directly here.
What is on the laboratory desk?
Transporting long glass tubing vertically to avoid breakage, and the action that will cause hot glassware to instantly shatter.
What is immersing hot glass in cold water?
Keeping your work area tidy, pushing your chair under the desk, and staying out of this restricted school zone unless given explicit permission.
What is the science storage/prep room?
The exact, vital sequence required when diluting strong acids, particularly sulfuric acid, to prevent dangerous heat generation or splashing
What is adding Acid to Water (AA)?
Knowing the physical location of all emergency gear, and the toxic liquid substance you must absolutely never touch if a thermometer breaks.
What is safety equipment and mercury?
Since hot and cold glass look completely identical, this is the safe physical technique used to determine if a piece of glassware is cool enough to grasp.
What is bringing the back of your hand close to it prior to touching?
Carrying sharp tools down/away, lubricating glass tubing before insertion, using distilled water only as intended, and ensuring hands are dry before touching an electrical switch
What is safe handling of specialized tools and equipment?
