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

The IDLH for H2S
100 ppm

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

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.

Mixed with air in correct proportions, H2S is
Explosive

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.

What must you have to wear a respirator
Medical evaluation and a fit test

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.

What are the two types of breathing apparatuses approved for H2S
SCBA and SABA

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.

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.

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

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)
