Here are the hazards of the chemical from the leak
ClF3 is a very strong oxidizing and fluorination agent. It is extremely reactive with most inorganic and organic materials, even plastics, and will initiate the combustion of many materials without an ignition source. These reactions are often violent, and in some cases explosive. Reaction with several metals give chlorides and fluorides; phosphorus yields PCl3 and PF5; and sulfur yields SCl2 and SF4. ClF3 is also violently reactive with water, in which it hydrolyses to a variety of hazardous chemicals such as hydrofluoric acid. H2S explodes on being mixed with ClF3 at room temperature.

The ability to surpass the oxidizing ability of oxygen leads to corrosivity against oxide-containing materials often thought as incombustible. In an industrial accident, a spill of 900 kg of chlorine trifluoride burned itself through 30 cm of concrete and 90 cm of gravel beneath.[8] Any equipment that comes into contact with chlorine trifluoride must be carefully selected and cleaned, because any contamination can ignite on contact. In addition, most general-purpose fire control/suppression hardware (Class A/B/C/K) is either incapable of suppressing this oxidation or can aggravate it; chlorine trifluoride has been reported to burn sand, asbestos, and other highly fire-retardant materials, reacts violently with water-based suppressors, and oxidizes in the absence of atmospheric oxygen, rendering atmosphere-displacement suppressors such as Halon and CO2 ineffective. It ignites glass on prolonged contact.[9]

Exposure of larger amounts of chlorine trifluoride, as a liquid or as a gas, ignites tissue. The hydrolysis reaction with water is violent and exposure results in a thermal burn. The product of hydrolysis is mainly hydrofluoric acid and hydrochloric acid, usually released as steam or vapor due to the highly exothermic nature of the reaction. Hydrofluoric acid is corrosive to human tissue, absorbs through skin, selectively attacks bone and stimulates pain nerves, and causes a potentially lethal poisoning. Hydrochloric acid is secondary in its danger to living organisms, but is more corrosive to most inorganic materials than hydrofluoric acid.

They should make coffee creamer out of it.

Where is the information about the leak?
old news you are already

It was in the news awhile back. Not much was said, and no follow story either. There was probably a better story about a business or church.

It's in your coffee if you are using tap water. Yum!

The reason nothing else was said about it was because it was such a small leak there was no damage to any thing and no one was injuried. They all took the proper actions and when they tested the building for air born particals it was no higher than normal.
