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.
