Jeopardy Final Round
100

When released to the atmosphere, H2S will seek to go to these areas.  Why?

Low lying areas.  Because H2S is heavier than Air.

Be cautious of ditches, cellars, downhill areas.

Air Vapor Density - 1

H2S Vapor Density - 1.9

100

The IDLH for H2S

100 ppm

100

My personal monitoring is alarming.  What do I do

Evacuate

100

What is the first priority in rescuing a victim from an H2S environment

Protecting yourself

100

What record did Lebron James just break?

NBA All Time Scoring Record

200

H2S reacts with water to form this acid

Sulfuric acid

Car batteries contain 30-50 precent Sulfuric Acid. 

Sulfuric Acid is corrosive to skin, eyes, teeth, and lung.  Can also lead to death in severe exposures.

Also causes corrosion and pitting of steel. 

200

The PEL for H2S

20 ppm

200

If downwind of an H2S release, you should move

Crosswind


200
What is the main route of entry for H2S?

Inhalation - Is the main method. 

H2S can also enter the body through:

Ingestion, Injection, and Skin Absorption.

200

What book has the most sold copies of all time?

The Bible - +5 billion copies sold.


300

Mixed with air in correct proportions, H2S is

Explosive

300

The odor threshold for H2S

0.1 ppm

300

When should you bump test your personal H2S monitor (two answers)

Bump Test - Monthly

Calibrate - 180 days

Note: Confined Space and Hot Work jobs require a more frequent calibration.  

300

What must you have to wear a respirator

Medical evaluation and a fit test

Once benched at half time during a national championship game, this 2nd round draft pick went on to quarterback his NFL team to a Super Bowl.

Jalen Hurts

This is a by-product of burning H2S

Sulfur dioxide (SO2)

-Highly Toxic, Colorless, Smell - burned match, heavier than air (2.6 VD).

-At high concentrations, S02 can cause the lungs to fill up with fluid, asphyxiating the exposed person. 

-Can also cause chemical pneumonia.

400

How many ppm are in 1%

 10,000 ppm

400

True or False:  The nose is a reliable source for indicating H2S.  

Why?

False. The nose is not a reliable source. 

H2S causes olfactory fatigue, paralyzing (deadening) the sense of smell. 

400

What are the two types of breathing apparatuses approved for H2S 

SCBA and SABA

400

Who won the FIFA World Cup 2022?

Agentina

500

Formed when H2S reacts with steel

-Iron sulfide

Iron Sulfide is pyrophoric and can spontaneously ignite upon contact with air. 

500

The H2S auto ignition temperature is:

500 degrees F

-A cigarette burns at 1400 degrees F. 

500

Your personal monitor should be worn in this area 6" to 12" from your face.

Breathing Zone

ANSI recommends that the monitor be worn on the chest. 

500

At what H2S concentration should you don a respirator

10 ppm

500

Who is the shortest player to ever play in the NBA?

Muggsy Bogues - 5'3"

600

H2S will dissolve in (3 answers)

Oil, water and sludge

600

The LEL and UEL of H2S

 4.3% and 43%

600

Your personal monitor will alarm at what H2S concentrations

10 ppm Low Alarm and 15 ppm High Alarm

Low Alarm: Indicated by slower set of flashing lights and sound.

High Alarm: Rapidly flashing lights and sound. Also accompanied by vibration. 

600

What is the action limit for H2S?

10 ppm


600

What All Star - Record Breaking - NBA player claims he can't palm a basketball?

Charles Barkley

Briefly describe how H2S affects the body. 

It will suffocate you by paralyzing the respiratory control center in the brain. 

You will cease to breath and cardiac arrest may follow.

Alcohol or drugs can quicken this process. 

700

Instant death occurs at what concentration

 1000 ppm

700

Explain the process for calibrating your gas monitor.

1. Place your monitor face down in one of the slots of the docking station. 

2. GREEN Button = Calibrate / RED Button = Bump

3. Wait for calibration to end (approx. 2 min.) 

(Red Light = Test/Cal. Fail) / (Green Light = Pass)

700

The distance surrounding an H2S release where the concentration of H2S will remain at a constant level level for a 24-hour period by way of continuous emission

Radius of Exposure (ROE)

Oklahoma Sooners!

Just kidding... it's the raiders of oakland. :(
