Elevator lift control electromechanical fire
I'm not talking about the buttons you push in the elevator to get you to the floor you want to go to. I'm talking about the inner workings of the elevator, the main computer and circuit boards, the hydraulic or mechanical engine. What we encountered late last night was very similar to pictures 2 and 3. What would you do, what are some hazards you notice, how would you tackle a fire such as this?

An aside; Can anyone tell me why neither the html or img codes for pictures work anymore?

Take the electrical out of the equation, kill the box. Then you are usually left with a small but very smokey class A or B fire. CO2 works nice to minimize collateral damage.

Inserted photos... Oldman's comments pretty much cover things.

Arrive on scene, scene size-up, establish command, obtain tactical channel, open the knox box and obtain master key, life safety wins... so I would evacuate the building if not already done so, then request facility representative and facility maintenance supervisor to the CP. Obtain verbal information from people meeting the first due company to determine if the or any elevator's are potentially occupied or not. Potentially use the maintenance rep to assist a company to locate the main electrical utility room usually remote from the elevator, immeidately shut off the power to the elevator, use the facility rep's knowledge if there is built-in advanced smoke evacuation HVAC controls, assign a crew to locate the elevator maintenance room where this control box is burning/smoking, have them don SCBA before entering this closed and locked room, enter cautiously, using TIC, flashlights the greatest hazard is IDLH and potentially high voltage energized electrical, shut off the "individual" maintenance power control switch for the elevator, attack or contain the fire with CO2 or Dry Chemical. Establish a crew to manually open and evacuate the elevator car which should have recalled to the ground floor per fire alarm codes and standards if in alarm. Determine if the elevator is unoccupied. Once fire is controlled and confirmed no extension into shafts or voids, PPV the building for smoke removal if facility does not have built-in advanced smoke evac capability. Lock out / tag out the elevator maintenance switch. Contact Fire Alarm tell them we are under control.... Request fire prevention- fire investigation to the scene.
Companies taking up.

We pretty much did exactly what you just said, not exactly to the T, but close. We have our own keys to the building, we made entry to the mechanical/maintenance room, but we do not have a key to the elevator control room, located within the mechanical/maintenance room. Maintenance arrived on scene directly after we did, and he did not have a key to the room either. It's safe to say that will soon be remedied. So, we had to force the door, a steel security door, that was fun!
