Vapor Density (VD) — the mass per unit volume of a given vapor/gas relative to that of air. Thus, acetaldehyde with a vapor density of 1.5 is heavier than air and will accumulate in low spots, while acetylene with a vapor density of 0.9 is lighter than air and will rise and disperse. Heavy vapors present a particular hazard because of the way they accumulate if toxic they may poison workers if nontoxic they may displace air and cause suffocation by oxygen deficiency if flammable, once presented with an ignition source, they represent a fire or explosion hazard. Gases heavier than air include carbon dioxide, chlorine, hydrogen sulfide, and sulfur dioxide. 

Hydrogen sulfide gas Hydrogen sulfide is a gas with a rotten egg odor. This gas is produced under anaerobic conditions. Hydrogen sulfide is particularly dangerous because it dulls your sense of smell so that you don t notice it after you have been around it for a while and because the odor is not noticeable in high concentrations. The gas is very poisonous to your respiratory system, explosive, flammable, and colorless. 

Hydrogen sulfide is a colorless, flammable gas under normal conditions. It is commonly known as hydrosulfuric acid, stink damp, and sewer gas. Hydrogen sulfide smells like rotten eggs. People can smell hydrogen sulfide at concentrations as low as 0.5 parts of hydrogen sulfide per billion parts of air (ppb, 1 ppb is 1,000 times less than 1 part per million [ppm]). However, at concentrations over 100 ppm most people can no longer smell hydrogen sulfide, which makes it... 

Hydrogen sulfide is removed from natural gas by passage over iron sponge, when flammable iron sulfide is produced. Handling precautions during regeneration of the reactor beds are detailed. 

Potassium nitride and other alkali metal nitrides react with sulfur to form a highly flammable mixture, which evolves ammonia and hydrogen sulfide in contact with water. 

Clear white to yellow-pink deliquescent crystals with an odor like rotten eggs due to formation of hydrogen sulfide. Commercial material may be yellow or brick-red lumps or flakes. It is unstable and discolors upon exposure to air. It undergoes autoxidation to form polysulfur, thiosulfate, and sulfate. It absorbs carbon dioxide from the air to form sodium carbonate. Moist sodium sulfide is spontaneously flammable upon drying in air. This material is hazardous through ingestion and produces local skin/eye impacts. 

Colorless gas with a disagreeable odor like hydrogen sulfide. It decomposes slowly on standing depositing elemental antimony. This material is hazardous through inhalation. It is highly flammable.

Hydrogen sulfide is a highly toxic and flammable gas. A 5-minute exposure to 1,000 ppm concentration in air can be fatal to humans (Patnaik, P. 1999. A Comprehensive Guide to the Hazardous Properties of Chemical Substances, 2nd ed. New York John Wiley). The symptoms are headache, nausea, nervousness, cough, eye irritation, and insomnia. High doses can produce unconsciousness and respiratory paralysis. 

Hydrogen sulfide is a poisonous, flammable gas that can contaminate and dissolve in process fractions, especially residual oils. It is also soluble in water that may be dispersed in these same residual oil streams.
