INTRODUCTION
CAP Safety Meetings – GENERAL SAFETY PART 32
�All personnel working
in an area where
concentrations of
Hydrogen Sulfide may
exceed the 10 parts per
Million (PPM) should
be provided with
training before
beginning work
assignments.

� Potential Hazard:
• H2S exposure greater than the Permissible Exposure Limit (PEL)
� Possible Solutions:
• Implement an H2S contingency plan (see API) including, but not limited to: Appropriate instruction in the use of hydrogen sulfide safety equipment to all personnel present at all hydrogen sulfide hazard areas
• Gas detection where hydrogen sulfide may exist

workers in H2S operations. Example topics include:
• Identification of the characteristics, sources, and hazards
of Hydrogen Sulfide
• Proper use of the Hydrogen Sulfide detection methods
used on the site
• Recognition of, and proper response to, Hydrogen Sulfide
warnings at the workplace

� Hydrogen Sulfide or sour gas (H2S) is a flammable,
colorless gas that is toxic at extremely low
concentrations.
� It is heavier than air, and may accumulate in low-
lying areas.
� It smells like "rotten eggs" at low concentrations and
causes you to quickly lose your sense of smell.
� Many areas where the gas is found have been
identified, but pockets of the gas can occur
anywhere.

� Iron sulfide is a byproduct of many production
operations and may spontaneously combust
with air.
� Flaring operations associated with H2S production
will generate Sulfur Dioxide (S02), another toxic gas.
� Active monitoring for hydrogen sulfide gas and good
planning and training programs for workers are the
best ways to prevent injury and death.
