Safety
Hydrogen sulfide is a highly toxic and flammable gas (flammable range: 4.3–46%). Being heavier than air, it tends to accumulate at the bottom of poorly ventilated spaces. Although very pungent at first, it quickly deadens the sense of smell, so potential victims may be unaware of its presence until it is too late. For safe handling procedures, a hydrogen sulfide material safety data sheet (MSDS) should be consulted.
In 1975, a hydrogen sulfide release in Denver City, located in Yoakum and Gaines counties, Texas, caused the state legislature to focus on the deadly hazards of the gas. State Representative E L Short of Tahoka in Lynn County, took the lead in endorsing an investigation by the Texas Railroad Commission and urged that residents be warned "by knocking on doors if necessary" of the imminent danger stemming from the gas. One may die from the second inhalation of the gas, and a warning itself may be too late.

Famous quotes containing the word safety:
“There is no calamity which a great nation can invite which equals that which follows a supine submission to wrong and injustice and the consequent loss of national self-respect and honor, beneath which are shielded and defended a people’s safety and greatness.”
—Grover Cleveland (1837–1908)
“I nightly offer up my prayers to the throne of grace for the health and safety of you all, and that we ought all to rely with confidence on the promises of our dear redeemer, and give him our hearts. This is all he requires and all that we can do, and if we sincerely do this, we are sure of salvation through his atonement.”
—Andrew Jackson (1767–1845)
“Once women begin to question the inevitability of their subordination and to reject the conventions formerly associated with it, they can no longer retreat to the safety of those conventions. The woman who rejects the stereotype of feminine weakness and dependence can no longer find much comfort in the cliché that all men are beasts. She has no choice except to believe, on the contrary, that men are human beings, and she finds it hard to forgive them when they act like animals.”
—Christopher Lasch (b. 1932)
