Midterm Exam Laboratory
Safety| Questions and Answers
University labs are not subject to OSHA regulations. - -False
- In the ChemAlert color coding system for storing chemicals, red signifies
toxic. - -False
- Acids and bases are both classified as corrosives, so they can be stored
together on the same shelf in a corrosion-proof cabinet. - -False
- OSHA stands for - -Occupational Safety and Health Administration
- The written document that outlines employee training, proper lab safety
protocols, employee health monitoring requirements, and names a Chemical
Hygiene Officer is called - -Chemical Hygiene Plan
- The flash point for a flammable substance is lower than the flashpoint of a
combustible substance. - -True
- Which flammable gas is produced when calcium carbide is mixed with
water? - -Acetylene
- "The 10 Worst Lab Accidents" posted on Canvas highlighted a chemistry
lab accident where nickel hydrazine perchlorate exploded when - -Friction
was applied
- Alkali metals, such as sodium and cesium, can react intensely with water.
What are these types of reactions? - -Exothermic
- Hydrofluoric acid is commonly used in geology as a way to extract
microscopic bosses from sedimentary rock. The rock dissolves in the acid,
leaving the acid insoluble fossils behind. This can cause burns of spilled on
the skin. Unless gluconate Joe is applied to these birds, the high dose of
fluoride could cause - -Hypocalcemia
- Pyrophoric materials can ignite when exposed to air. - -True
- "The 10 Worst Lab Accidents" posted on canvas highlighted an accident
where is physics student working alone at night in a machine shop was killed
when - -Her hair got caught in a lathe, strangling her.
- A dust fire can occur when fine dust particles are exposed to water - -False
, - When a strong oxidizer (such as potassium permanganate) is mixed with
an organic compound (such as glycerin), it will start a fire. - -True
- In the video, "Practicing Safe Science", several incidents of severe skin
burns occurring in molecular biology labs were described. These burns were
all due to - -Phenol
- What term describes the study of the incidence of disease within a
population? - -Epidemiology
- Drinking an amount of water above a certain dose can kill a person. - -
True
- What is the most common occupational route of exposure? - -Inhalation
- All natural products (from plants, mushrooms, etc.) are safe because they
are normally found in nature. - -False
- What is the specific term for a chemical or agent that causes a change in
DNA sequence? - -Mutagen
- Threshold limit values (TLVs) set by the American conference of
government industrial hygienist (ACGIH) are the legal limits/standards for
chemical exposure in the workplace. - -False
- Which of the following is a non-transmissible disease? - -Diabetes
- What is the meaning of the laboratory warning sign with a skull and
crossbones? - -Toxic
- What type of organism is used to perform the Ames test? - -Bacteria
- In a graph the bottom point of the graph before it slopes up is the ———
point and where the 50% point intercepts the dose is ——— - -threshold;
LD50
- What is the acceptable rate of death due to chemical exposure at work in
the United States? - -1 death per 100,000 people
- Which section of a chemical's SDS contains information regarding chemical
incompatibilities when storing that chemical? - -7
- Match the following types of toxins with their target organ/system.
- neurotoxin
- pulmonary toxin
