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.
If you suspect a natural gas leak inside, immediately stop what you're doing (do not flip any electrical switches, unplug anything or use a telephone) and go outside. Inhaling high concentrations can also lead to asphyxia (when the body is deprived of oxygen) and possibly death.
