Mod 1 Lesson 3 Flashcards
acid
a chemical compound with a pH < 7 that neutralizes with bases
autoclave
a strong, high-heat appliance used for processes using high pressures and temperatures; most often steam sterilization in laboratory settings
biosafety
the application of safety precautions to reduce risk of exposure to a potentially infectious microbe or biohazard and to limit the contamination of the environment and community
carcinogen
a cancer-causing agent
chemical
a substance or mixture of substances found on the Periodic Table of Elements
corrosive
any chemical that will damage or destroy another substance (e.g., strong acids, strong bases, and strong oxidizers)
flash point

Globally Harmonized System (GHS)
a universally understood set of symbols for hazardous materials created by the United Nations in the 1990s
laboratory bench
a workplace for conducting experiments and scientific research
microbe
an organism, such as bacteria or a virus that is too small to be seen by the naked eye
NFPA label

nonpathogenic
does not cause disease, harm or death; is usually used to describe bacteria
personal protective equipment (PPE)
any items or protective clothing used to ensure safety and reduce exposure
route of exposure: the way a microbe gains access to a living organism. Routes of exposure include: through broken or damaged skin, inhalation, via mucous membranes of the eyes, nose, and mouth, and ingestion
safety data sheet (SDS)
a reference sheet that details the properties, various hazards, protective measures, and other safety precautions for a specific chemical substance or mixture
