Driving is a strong indication that he is not aware.

Similar fun would likely be the safety sheet for FOOF (Dioxygen diflouride), a compound that you can't really get to room temperature without said compound tearing itself and it's container apart. I do recall it reacts "vigourosly" (I believe the paper I read on this used those specific words) with Chlorine triflouride at 90K (-180C, -300F).

To be fair, most stuff involving fluorine is like this. Compare https://fscimage.fishersci.com/msds/11171.htm (for extra chlorine trifluoride fun, this is one of the things you get if you react it with... water. Hence the entry in "unsuitable extinguishing media".):

> Danger! May be fatal if inhaled, absorbed through the skin or swallowed. Both liquid and vapor can cause severe burns to all parts of the body. Specialized medical treatment is required for any exposure... can cause metabolic imbalances with irregular heartbeat, nausea, dizziness, vomiting and seizures. Long-term exposure may cause bone and joint changes. Will attack glass and any silicon-containing material. Corrosive to metal.

> Potential Health Effects

> Eye: Contact with liquid or vapor causes severe burns and possible irreversible eye damage.

> Skin: May be fatal if absorbed through the skin. Causes severe burns with delayed tissue destruction. Substance is rapidly absorbed through the skin. Penetration may continue for several days. Causes severe tissue necrosis and bone destruction.

> Ingestion: Causes severe digestive tract burns with abdominal pain, vomiting, and possible death.

> First Aid Measures

> Eyes: Do NOT allow victim to rub eyes or keep eyes closed. SPEEDY ACTION IS CRITICAL! GET MEDICAL ATTENTION IMMEDIATELY!

> Skin: Discard contaminated clothing in a manner which limits further exposure. Destroy contaminated shoes. Spills should be flushed until medical attention arrives. SPEEDY ACTION IS CRITICAL! GET MEDICAL ATTENTION IMMEDIATELY.

> Ingestion: Get medical aid immediately. SPEED IS ESSENTIAL. A DOCTOR MUST BE NOTIFIED AT ONCE.

> Inhalation: SPEED IS ESSENTIAL, OBTAIN MEDICAL AID IMMEDIATELY. POISON material. If inhaled, get medical aid immediately.

(ALL CAPS are original to the MSDS.)

> Wear chemical splash goggles and face shield.

> Wear butyl rubber gloves, apron, and/or clothing.

> Wear appropriate protective clothing to prevent skin exposure.

> Wear a NIOSH/MSHA or European Standard EN 149 approved full-facepiece airline respirator in the positive pressure mode with emergency escape provisions.

> Never work alone with this chemical.

> Substance is noncombustible
