A process for producing an ozonide from an ethylenically unsaturated carboxylic acid having between 8 and 30 carbon atoms and one or more unsaturated carbon to carbon double bonds comprising the steps of contacting an ozone enriched gas with the unsaturated carboxylic acid in an absorber column having a trough at the top and a pot at the bottom having separate stages to form an ozonide; and operating a safety system comprising: monitoring an operating condition wherein the operating condition includes at least one of an operating temperatures within the column, the flow of ozone enriched gas having an ozone concentration between 0.5% to 12% through the column, the operating pressure of ozone enriched gas in the column, the flow of liquid reactant through the column, and the flow of product out of the column and assigning a value to the monitored operating condition; and wherein each operating condition is independently monitored; comparing the operating condition value with a threshold value for the at least one condition; affecting the formation of the product in response to the operating condition reaching the threshold value; wherein the operating condition value is a temperature in the absorber column and the threshold value is a first threshold temperature between 37°C (100°F) and 60°C (140°F); and wherein a sensor monitors the temperature within the column and a switch linked to the sensor stops the supply of ozone enriched gas to the absorber column by closing an ozone enriched gas valve and by causing the ozone generators to shut down by switching off supply of electricity to the generators if the temperature at any of the stages in the absorber column, or in the trough or in the pot is above the first threshold temperature value that is between 37°C (100°F) and 60°C (140°F); and wherein the threshold value further includes a second threshold temperature that is greater than the first threshold temperature, and the second threshold temperature is between 43°C (110°F) and 66°C (150°F), and wherein a second independent temperature monitor detects the temperature of stages within the column and if the temperature exceeds or reaches the second threshold temperature but is less than the critical temperature a switch linked to the second temperature sensor causes the ozone generators to shut down, the ozone enriched gas valve supplying the absorber column to close, and water valves are opened to the stage where the second threshold temperature was exceeded and the formation of the product in that stage in response to the temperature reaching the second threshold value is affected by direct addition of water into the absorber column. monitoring an operating condition wherein the operating condition includes at least one of an operating temperatures within the column, the flow of ozone enriched gas having an ozone concentration between 0.5% to 12% through the column, the operating pressure of ozone enriched gas in the column, the flow of liquid reactant through the column, and the flow of product out of the column and assigning a value to the monitored operating condition; and wherein each operating condition is independently monitored; comparing the operating condition value with a threshold value for the at least one condition; affecting the formation of the product in response to the operating condition reaching the threshold value;
