The engineering control that captures and removes air contaminants from the source of emission.

What is local exhaust ventilation?

100

The amount of energy required to displace an electron.

What is ionization potential?

100

The founder of industrial hygiene who wrote the book On the Dangerous Trades.

Who is Alice Hamilton?

100

Light Amplification by Stimulated Emission of Radiation

What is a L.A.S.E.R?

100

Basic unit of matter in Chemistry; it is composed of a nucleus and electrons. 

What is an Atom?

200

Typically measured in cubic feet per minute and is the product of the area of a duct multiplied by the velocity of air flowing.

What is volumetric flow rate (Q)?

200

The most common type of absorbent made from coconut shell or petroleum.

What is activated charcoal?

200

The father of toxicology: the dose makes the poison (paraphrased). 

Who is Paracelsus?

200

The amount of time it takes 50% of the radioactive atoms to decay to a stable state.

What is half-life?

200

The number of protons and neutrons in the nucleus. 

What is Atomic mass?

300

Includes a Hood, Duct, Air cleaner, Fan and Exhaust

What is the basic local exhaust system?
300

A passive monitoring operation that relies on the movement of contaminant molecules across a concentration gradient.

What is Diffusion Theory sampling or Fick’s first law?

300

The father of medical microbiology, famous for treating milk and wine to stop bacterial contamination.

Who is Louis Pasteur?

300

Intensity is inversely proportional to the square of the distance.

What is inverse square law?

300

An element that has equal number of protons but different number of neutrons.

What is an isotope?

400

Fluid motion characterized by chaotic changes in pressure and flow velocity. For example, storing items in a hood negatively affects fume hood performance. 

What is turbulence?

400

Glass tubes packed with inert, solid, granular material coded with a chemical agent that changes color when a vapor is pulled through.

What are colorimetric tubes?

400

First scientist to demonstrate that cancer may be caused by an environmental carcinogen, namely chimney sweeps' carcinoma.

Who is Percivall Pott?

400

Type of radiation that is best shielded by skin or paper but does the greatest internal damage.

What are alpha particles?

400

The total pressure of a mixture of gases is equal to the sum of the pressure of each gas.

What are partial pressures?

500

A device consisting of two concentric tubes: one measures the total or impact pressure existing in the air stream, and the other measures the static pressure.

What is a Pitot tube?

500

A calibration classification that involves movement of a bubbler piston, and a chamber of a known fixed volume. 

What is a primary standard?

500
He/she wrote De Morbis Artificum Diatriba (The Diseases of Workmen) and is considered the founder of occupational medicine. 
Who is Bernardino Ramazzini? 
500

The amount of biological damage produced by a specific radiation and a given exposure.
