Accident An unplanned event that results in the damage to or loss of property, limb or life. The law requires that an accident be reported if it results in an employee being required to be absent from work for more than two days.  
Auto Ignition Temperature The temperature at which an explosive mixture ignites without an external source of ignition.  
Explosive Limit A concentration of a contaminant in air such that the mixture will just propagate a flame. For almost all contaminants there is a lower concentration below which the mixture will not propagate a flame  
Flash Point The temperature at which a flammable liquid produces a sufficient amount of vapour to just flash a flame across the top, if a source of ignition is supplied close to the surface. The flash point is to be distinguished from the Fire point .  
Fire Point The temperature at which a flammable liquid produces a sufficient amount of vapour to produce and sustain a flame if a source of ignition is supplied close to the surface. The flash point is to be distinguished from the Fire point .  
Incident An unplanned event that would have resulted in the damage to or loss of property, limb or life, had someone, been in the vicinity of the unplanned occurence.  
Maximum Acceptable Concentration Also known as: Maximum permissible concentration, threshold concentration, threshold limit, maximum allowable concentration. The value below which it is considered desireable to maintain the concentration of an air-borne contminant.  
Maximum Permissible Concentration Also known as: Maximum Acceptable Concentration, threshold concentration, threshold limit, maximum allowable concentration. The value below which it is considered desireable to maintain the concentration of an air-borne contminant.  
Maximum Allowable Concentration Also known as: Maximum Acceptable Concentration , threshold concentration, threshold limit, Maximum Permissible Concentration. The value below which it is considered desireable to maintain the concentration of an air-borne contminant.  
Threshold Concentration Also known as: Maximum Acceptable Concentration, Maximum Permissible Concentration, threshold limit, maximum allowable concentration. The value below which it is considered desireable to maintain the concentration of an air-borne contminant.  
Threshold Limit Also known as: Maximum Acceptable Concentration, threshold concentration, threshold limit, maximum allowable concentration. The value below which it is considered desireable to maintain the concentration of an air-borne contminant.
