Quiz on H2S Safety | Questionnaire on Hazards of Hydrogen Sulfide Gas
Quizzes are the best
way to educate workers and employees in interesting way and also helps to
validate the training effectiveness. This quiz on hazards
of hydrogen sulphide gas helps you to test your knowledge on H2S
and identify your strengths and weaknesses.
Hydrogen Sulfide (H2S), a highly toxic and flammable gas, is
a naturally occurring chemical compound produced during the decomposition of
organic matter.
H2S is colorless and heavier than air,
soluble in both water and oil, and is often found in places such as peatlands,
swamp and sewers. It is natural gas deposits crude oil and get release during
oil exploration and oil refining process.
This Hydrogen Sulfide quiz helps
you understand the deadliest physical & Chemical properties of H2S. You
will also learn the safety hazards associated with it in Oil and Gas
installations and what are the best safety measures requires to manage the
risk. This H2S questionnaire formulated with
ref to its safety data sheet and experience in Oil and Gas industries.
This quiz
on Hydrogen
Sulfide includes 16 multiple choice questions and answers, with each
question having four answer options. You have to select the correct one by
clicking on it, the green highlight indicates the correct answer, while the red
is the wrong answer. At the end of the test, your total score will appear.
Let's start
the quiz and test your knowledge of hazards of Hydrogen Sulphide Gas.

Q9. H2S
combines with water to form ___________, a strongly corrosive acid.
Q.10. Corrosion due to H2SO4 is often
referred to as _____________
Q.11. Due to
presence of H2S in crude oil, iron sulfide forms a scale at low

Q.12.
According to OSHA PELs, general Industrial Ceiling limit of H2S is _________
Q.13.
According to OSHA PELs, general Industrial peak limit of H2S is _________
Q.14.
According to OSHA PELs, Construction 8-hour limit of H2S is _________
Q.15.
According to OSHA PELs, Shipyard 8-hour limit of H2S is _________
Q.16.
__________ Odor threshold of H2S i.e. When rotten egg smell is first noticeable
to some.
This Questionnaire
on H2S can be shared with employees and workers to make them
understand the hazards of hydrogen sulfide gas and follow the safety
precautions to minimise the risk at ALARP level.
Hydrogen sulfide is deadliest gas capable of
submerging and killing almost instantly in the highest concentrations. Its
corrosive and flammable property possess a great danger to workers at oil and
gas sites.
Hydrogen sulfide has an unpleasant rotten egg smell
in low concentrations and is heavier than air thus remains close to the ground
and can accumulate in low areas or confined spaces, including mud pits, gas
vents, basements and substructures.
This Quiz on hazards of H2S gas can also
be used as an important tool to raise awareness of safety so that people can
understand the hazards and risk of hydrogen sulfide.
This questionnaire is very useful for peoples working
in crude oil exploration, rig and refining operations.
