MEK (Methyl Ethyl Ketone, Butanone) has a NFPA 704 rating of 3 for flammability (Red diamond).
3. Liquids and solids that can be ignited under almost all ambient temperature conditions (e.g., gasoline). Flash point below 38°C (100°F) but above 23°C (73°F).
DANGER! EXTREMELY FLAMMABLE LIQUID AND VAPOR. VAPOR MAY CAUSE FLASH FIRE.

It's my pot and I'll stir it if I want to. If you're not careful, I'll stir your's as well!

Thanks to everyone for their answers. To respond generaly:
The evacuation went very well and everybody gathered at their assigned places outside the building. We had practiced this a few times previously.
Nobody will be fired and all the occupants of the building are going to be retrained by the end of this coming Thursday. The managers and supervisors already had a briefing this morning with PowerPoint slides etc etc.
In short, lessons learned and the culprits are suffficiently contrite. Doubt if this exact same thing will happen again.
An hour after the session this morning a couple of guys came to me complaining of someone using some really strong adhesive. The girl using the adhesive did obey some of the rules and had on the approved mask so figured that she was doing a good job. Only one small problem. She was working in a semi-confined space (a big tube open at both ends) and ignored everybody else working in the area, so was poisoning their air. She also thought that she was doing good by placing a big fan at one end of the tube. The poor inspector sitting at his desk close to the exit now received the full benefit of the fumes. It sure is hard to get the safety message through to everybody all the time!

Mexstan getting people to think before they act will always be a challenge.
I have been in shops around the world and there is always someone trying to take a short cut and do something they know is wrong without getting caught.
I know NOTHING about your industry or shop practices, but one thing that is common in oil field shops is a tool box talk. any job is discussed with management and everyone involved. It doesn't matter if its unloading a truck with a rented crane or bolting a flange together. Everyone discusses who is to do what and who is responsible for what. Also gives you a chance to discuss the dangers of the activity being performed and the limitations of the equipment involved (a crane operator will know where his blind spots are and instruct people to stay out of that area)
