Chemistry Lab Safety Review

Flashcards covering general chemistry laboratory safety rules, emergency procedures, and proper equipment handling based on the lab safety practice guide.

Working Alone

Individuals are prohibited from working alone in the laboratory, even if they understand the experiment.

Unclear Instructions

If a student does not understand a laboratory instruction, they must ask the teacher before continuing.

Prohibited Items

Food, drinks, and gum are strictly prohibited in the laboratory.

Authorized Experiments

Only experiments listed in the procedure are allowed; unauthorized experiments are prohibited even if they seem safe.

Lab Behavior

Horseplay, practical jokes, and pranks are considered dangerous and are prohibited in the work area.

Fume Hood Safety

A student must never place their head inside a fume hood to see an experiment more clearly.

Waste Disposal

Chemical waste should not always be poured into the sink; students must follow specific teacher instructions for disposal.

Laboratory Hygiene

Keep hands away from your face, eyes, and mouth while working with chemicals.

Proper Lab Attire

Includes safety goggles, secured long hair, no dangling jewelry, no loose clothing, and fully covered feet (no open-toed shoes).

Accident Reporting

Every accident or injury must be reported to the teacher immediately, regardless of how minor it appears.

Eye Splash Protocol

If a chemical splashes into the eyes, flush with water for at least $15$ minutes and notify the teacher.

Chemical Identification

Chemicals must never be tasted or smelled to identify them.

Handling Unused Chemicals

Unused chemicals should never be returned to their original containers; follow teacher disposal instructions instead.

Pipet Usage

A pipet should be filled using a rubber bulb or pipet pump, never with your mouth.

Acid Dilution Rule

When diluting an acid, always add the acid to water.

Flammable Liquids

Substances that are flammable must be kept away from open flames and other heat sources.

Broken Glass Handling

Broken glass must never be picked up with bare hands; use a brush and dustpan to place it in a designated container.

Glassware Inspection

Chipped or cracked glassware should never be used in an experiment.

Electrical Safety

Ensure hands are dry before touching electrical switches or plugs, and always grasp the plug rather than pulling the cord to remove it from an outlet.

Thermal Shock in Glassware

Hot glassware may shatter if placed directly into cold water.

Heating Test Tubes

Never point the open end of a heated test tube toward yourself or another person, and never look directly into it.

Lit Burner Safety

A lit burner or heating substance must never be left unattended and should be turned off when not in use.

Fire Drill Protocol

During a fire drill, close all containers and turn off gas, fume hoods, and electrical equipment.

Heat Detection Method

Determine if an object is hot by bringing the back of your hand near it without actually touching it.
