Orange Coast College Chemistry Laboratory Safety Flashcards

A comprehensive set of vocabulary and procedural flashcards based on the Orange Coast College Chemistry Laboratory safety rules, data handling protocols, and emergency procedures.

Primary data

Measurements, readings and observations made during an experiment recorded directly on experiment sheets in permanent waterproof ink at the time they are made.

Secondary data

Information recorded without direct measurement, such as calculations, chemical equations, and drawing structures, which must be recorded in pencil.

Unauthorized experiment

Anything that is not in the experimental procedures or instructions given by the professor.

Chemical safety goggles

Indirect vent eyewear meeting $ANSI\,Z87.1$ and $ISEA\,D3$ specifications that must be worn at all times when experiments are being done.

Eye and skin rinse duration

The minimum time ($15\,\text{minutes}$) required to rinse with water following chemical contact.

Determining the odor of a gas

The process of holding the container far away and gently waving (wafting) gas toward the nose.

$NaHCO_3$ (Sodium Bicarbonate)

The solid used to neutralize spilled acids or bases lab countertops.

Minor burn treatment

Quickly immersing the burned region in ice water for $15\,\text{minutes}$, ensuring ice is gathered before lighting a burner.

Run, Hide, Fight

The strategy used for an active shooter situation in the laboratory.

SDS (Safety Data Sheets)

Available from the instructor, these provide physical and chemical hazard information for chemicals used in experiments.

Palm on the label

The specific way to grasp a reagent bottle when pouring liquids so that drips occur on the side opposite the label.

Fire polishing

The process of holding the ends of glass tubing in a burner flame until the glass edges become rounded.

Glycerol

The substance used to lubricate holes in rubber stoppers before inserting fire-polished glass tubing or thermometers.

Nesting

Placing beakers inside each other, which is the leading cause of chipped spouts and should be avoided.

Waste Disposal: Acids and Bases

Materials that should be poured into the sink and flushed with large amounts of water.

Primary Data Correction

The procedure of lining out an entire error with one single line and writing the correction nearby without writing over digits.
