Core 10 introduction to hydrogen sulfideWayneBourg
Hydrogen sulfide, or H2S, is a hazard that can creep up on you. You cannot see it, and if the concentration is high enough, you will not even be able to smell it. This toxic gas is colorless and collects in low-lying areas. H2S is so powerful that it can kill you with one breath. It is known as “The Silent Killer.” In this chapter, we will review the safe work practices designed to protect you from hazardous exposure to H2S.

Introduction
Hydrogen sulfide (H2S) is a gas that naturally occurs in hot springs, crude petroleum, and even natural gas. This gas is usually produced by the breakdown of organic materials commonly found in wastes of human and animals by bacteria. Some of the activities that commonly result to the production of hydrogen sulfide gas include treatment of wastewater, drilling and even refining of petroleum or natural gas (Occupational Safety and Health Administration).
Aside from being in a form of gas, hydrogen sulfide may also exist as a gas, which is compressed to become a liquid. It is commonly found in places which are enclosed and hav ...
Hydrogen Sulfide (H2S)
Hydrogen sulfide is a colorless, flammable, extremely hazardous gas with a “rotten
egg” smell. Some common names for the gas include sewer gas, stink damp,
swamp gas and manure gas. It occurs naturally in crude petroleum, natural gas,
and hot springs. In addition, hydrogen sulfide is produced by bacterial breakdown
of organic materials and human and animal wastes (e.g., sewage).
Industrial activities that can produce the gas include petroleum/natural gas
drilling and refining, wastewater treatment, coke ovens, tanneries, and kraft
paper mills. Hydrogen sulfide can also exist as a liquid compressed gas.
MSDS is a document that contains information on the potential health effects of exposure to chemicals, or other potentially dangerous substances, and on safe working procedures when handling chemical products

5. IT’S THE LAW !
In the State of Texas, all persons working in the oil field where
H2S concentrations are known, MUST complete a H2S
certification course annually.
The objective is to educate employees about the physical &
chemical properties, toxicity, concentration levels, personal
protective equipment use, detection measures, rescue and first
aid.
The best way to reduce the chance of employee exposure to H2S
is to provide the best possible training, provide appropriate
personal protective equipment, and ensure employees follow
correct work procedures, rules and requirements.

19. By-products of Burning
When H2S is burned, it produces
Sulfur Dioxide
• Short-term exposures to high levels of
sulfur dioxide can be life-threatening.
Exposure to 100 ppm of sulfur dioxide is
considered immediately dangerous to life
and health (IDLH)
• PEL for SO2 is 2 ppm
• Sulfur Dioxide may cause heart
problems and respiratory disorders in
younger children and elders.
20. Flare stack
If the flare stack is burning away 100,000ppm H2S and
is burning at 80% efficiency, what is the ppm of H2S in
the exhaust plume?
100,000ppm. The flare stack is burning 80%
of the volume not the concentration.
21. 21
Iron Sulfide
H2S reacts with iron and steel which forms
iron sulfide which can be Pyrophoric !
Iron sulfide treated with acids results in
H2S being released.
23. 23
Metallurgy
H2S may react with iron and steel
causing hydrogen embrittlement
and/or sulfide stress cracking.
This lowers safety factors in tubular
and pressure vessels.
26. 26
Variables that determine the effects of H2S exposure
1. Time (how long)
2. Concentration (how much)
3. Frequency (how often)
4. Variables associated with the individual.
28. 28
What is a Part Per Million (ppm)?
One part in a Million Parts.
1 / 1,000,000
0.0001
1 ounce in 31.25 tons
1 minute in 1.9 years
1 drop of Vodka in 80 fifths of 7-up.
29. 29
Exposure Levels
PEL – 10 ppm / 8hr. TWA
STEL – 15 ppm / 15 min.
Ceiling Concentration – 50 ppm / once 10 min.
Human Lethal Concentration
100 - 800 ppm / 5min.
Revised IDLH – 100 ppm
PEL – 6.6 ppm / 12hr. TWA
PEL – 5 ppm / 16hr. TWA

• ELECTRONIC
• CHEMICAL REACTION
• NOSE
• The API-55 recommends that monitors be calibrated at least once a month.
• They should be calibrated after each use with a Cal-Gas up to 50% of the
maximum scale of the instrument. A 10% variance is allowed.
34. 34
The battery and sensor are sensitive
They work from a chemical reaction.
The reaction uses the chemical up.
When the chemical is used-up, the
battery or sensor dies.
Personal Monitor Limitations
35. 35
When the alarm sounds, leave the area
to a safe zone and not return until
the area is SAFE.
36. 36
Evacuate in an upwind / uphill
direction. Report to briefing
area immediately.
Do not return to the area
until someone using proper
detection equipment has
re-evaluated the area and
approved it safe to re-enter.
Contingency Plan
37. 37
H2S may be
present
Do not be misled by signs reading
caution H2S or warning H2S.
H2S Signs
Because of the characteristics of the gas. It has the ability to
accumulate in levels above IDLH (100ppm).
H2S may be
present
40. 40
All personnel on location must have a current one year H2S certificate
from a formal H2S course.
Beards & sideburns must be trimmed as necessary to assure the seal
on the SCBA face piece will be free of hair.
Upon arrival at well site, report to supervisor to receive H2S briefing.
• Familiarize yourself with the site’s Contingency Plan.
• NO SMOKING except in specifically designated areas.
• Inspect & practice putting on your specific breathing apparatus.
• Know the location of the “Safe Briefing & Assembly Areas.”
• Remain “Wind Conscious” at all times. Be prepared to move across
and “Upwind” in the event of an emergency involving an H2S release.
Possible Danger - No Alarms.
41. 41
• Go to “UPWIND” Safe Briefing Area if you are not specifically
designated to control the well.
• Be alert for change in weather conditions.
• Check your safety equipment for readiness.
• During an emergency, use the ”BUDDY SYSTEM” to prevent anyone
from entering or being left alone in a contaminated area.
• Report any indications of H2S to a supervisor.
• Extinguish ALL SOURCES OF IGNITION after an alarm has been
activated.
Moderate Danger - Intermittent Audible Alarm and Yellow
Flashing Light. 10 - 50 ppm H2S
42. 42
Extreme Danger - Continuous Audible Alarm and
Red Flashing Light. > 50 ppm H2S
• Same precautions as in Condition “Yellow.”
• Don your SCBA.
• Remain in Safe Briefing Area or Assembly Area and await
instructions for evacuation.
• Provide assistance to anyone who may be injured by
toxic gases.
• Personnel shall ensure that their breathing apparatus is
properly fitted and operational before entering an H2S
contaminated area.
