There was also another resource available that was created after another accident that was a part of the settlement. XYZ company had to form a resource to help prevent future accidents for X amount of years. Well... X amount of years has elapsed and XYZ company abandoned it because their legal obligation was completed.

A person having documented training or experience or both and be familiar with the operation and safety functions of the components and equipment. Training and experience may include recognizing the safety hazards and performing the procedures to which they are assigned in conformance with the requirements of the relevant building code. As outlined in 17.1.
If your building requires fire testing with devices in the hoist way, a plumber that needs access to the sump, a mason or any other trade that does not meet the requirement of “Elevator Personnel” they shall not have access to the hoist way.
There have been several accidents and fatalities with non elevator personnel accessing elevator hoist ways. Take the time to call your elevator service provider and have them assist you in getting in and out of the elevator hoist way safely.

Get this out of the machine room College!
No jumpers sign on the controllers. This is a generally accepted good idea and a part of the elevator code.
Perhaps we didn't see the sign on the controller
It has been many years since the head was wiped off
Good elevator maintenance practices will reduce shut downs, prolong equipment life, allow for easier future maintenance and increase the safety of the elevator equipment. You will not make a immediate return by performing proper maintenance but in the long term there is a benefit for all parties.
The problem with public bids is that usually the low price comes with the lowest level of service. So perhaps the building doesn't want to pay for a good maintenance program, perhaps the elevator contractor doesn't allow the time for the elevator mechanic to complete elevator maintenance, or perhaps the elevator mechanic is complacent and uses this group of buildings to pad time. This idea is something the building owner, elevator contractor and elevator maintenance tech all need to have buy in for.

This seems like a fairly straight forward item, “it is important to have the correct data tags on elevator equipment”. This is the 2nd experience I have had in the last few months where I have run into the incorrect information on devices which may have caused unnecessary issues with the elevator system.
Experience #1 - The most recent experience was at a school we are modernizing. The elevator had been shut down for a long period of time. I went to get the voltage off the disconnect and saw they had small wires so I assumed it was 480vac. I needed the motor information as well, the power unit did not have a motor tag so I looked for a controller tag and found the tag below.
Well I got the information on the motor horse power but this didn’t make sense. It is a 208 controller with 480VAC voltage.
I looked in the starter cabinet and found the tag below.
Perhaps the transformer dropped the voltage down at the starter to the controller but the amps are labeled incorrectly. What else is incorrect on the control system? This reminded me of a project we did with the same package company which everything was mislabeled, motor was wrong size, Oh yeah the floor to floor travel was wrong too.
Experience #2 – I got a call from a electrical engineer about an elevator that had an elevator on single phase with a converter to simulate 3 phase. This elevator had been shut down for a month after running for 11 years. He told me about this system and something didn’t make sense. If the elevator was running for 11 years with no issues I don’t know how the elevator system was the problem. I went to the building and looked at the disconnect, metered the disconnect, and identified the label on the disconnect was wrong. The elevator was correct, the converter was correct, the disconnect label was wrong. Previous to everyone’s involvement the elevator service company installed a solid state starter on the elevator that is fed by single phase w/3 phase converter and it didn’t work. The building hired an engineer who didn’t meter the disconnect and spent time trying to figure out why the elevator was ordered wrong. The elevator had run 11 years prior. Due to incorrect labeling it was out of service over a month, lots of speculation why, not sure if the elevator is running because I never heard from the engineer after I pointed this out to him. In this case the right solution may have been to put the mechanical starter back on. And/or get the electrician who installed the phase converter in the same room with the elevator company. This should have taken a few days, not a month.
Take away - Everyone makes mistakes, controller companies, electricians, elevator companies and even myself. If you have a wrong label, correct it by getting the correct information where it needs to go. While you may know the label is wrong, the next person may not. DO NOT TRUST LABELS, DO NOT TRUST WHAT SOMEONE WROTE ON THE CONTROLLER, DO THE DILIGENCE TO DOUBLE CHECK. MEASURE TWICE CUT ONE.

As an elevator contractor/mechanic it is difficult to get to all of our customers, fix their elevators, replace required parts, complete annual CAT 1 testing, complete annual fire testing and at times cleaning gets put on the back burner. We have been trying to clean up some accounts that we have had for many years and some of the buildings we have as new customers.
Most of the cleaning we are completing the building owner will never see as it is in the hoistway. Just a few elevators that had some build up of debris, dust, dirt, etc that we cleaned down the hoistway. Not only does it look better, it removes fire hazard. Too much dust will create a combustible environment due to particulate.
We are trying to also get to the elevator traction machines and find the lost art of painting elevator machines. The first picture is a elevator we modernized and painted the machine. The 2nd group is a newer account we are taking the time to paint the machine and machine room floor.
We are also trying to get to elevator machine rooms that could use a nice coat of paint on the floor. We picked up a account with 16 elevators and spent some time cleaning the machine rooms and putting a coat of paint on the floor.
In the fast paced day to day of we still believe it is important to make the elevator environment clean, when it is clean it is easier to work on.
