 There are 596 manholes that we have on base that we do periodic maintenance inspections on. Making sure that the cabling that we have is ready to go and those play a big role into how the work centers operate. Then we have PPE, which is our personal protective equipment. It's going to be our hard hats, our gloves, our glasses, our steel-toed boots. And that all helps us stay safe on the job. So right here we are putting on the safety harness for the A-frame that is behind us. And this keeps me safe inside of the manhole. We do air quality control to make sure that it's good to get inside. Then we go ahead and clean the tags to make sure that the labeling system is good for us to read just in case anything does happen that we do have the proper documentation. So those play a big role in how the work centers operate and I think our jobs are very important.
