Corticosteroids are also used supportively to prevent nausea, often in combination with 5-HT3 antagonists (e.g. ondansetron). Typical undesired effects of glucocorticoids present quite uniformly as drug-induced Cushing's syndrome.
Common causes. A gas explosion occurs when the gas/air mixture reaches a critical value, then any spark, flame or heat source can ignite the mixture. The explosion is caused when the rapidly expanding, burning gas is confined and builds up pressure. As the pressure builds, something has to give, and in a home gas explosion it is usually the windows.
The gas is highly flammable and can explode if the concentration in the air is between 4 percent and 45 percent. As a result of burning hydrogen sulfide, sulfur dioxide can be produced, according to the Centers for Disease Control and Prevention's Agency for Toxic Substances and Disease Registry (ATSDR).
