Filing a petition for a writ of certiorari to the U.S. Supreme Court does not automatically stay the mandate. Nonetheless, certiorari petitions are a common basis for asking an appellate court to issue a stay. Rule 41 expressly contemplates such motions.
The Fire Triangle. Three things are required in proper combination before ignition and combustion can take place---Heat, Oxygen and Fuel. There must be Fuel to burn. There must be Air to supply oxygen. There must be Heat (ignition temperature) to start and continue the combustion process.
Fire Prevention. A fire needs three elements - heat, oxygen and fuel. Without heat, oxygen and fuel a fire will not start or spread. A key strategy to prevent fire is to remove one or more of heat, oxygen or fuel. The risk assessment should include detail on all three elements to minimise the risk of a fire starting/ spreading.
