What happens when you try to do your job but have very little visibility?
The hygienist had never changed a bulb before so she went and got a co-worker who located a replacement.
That person wasn't sure how to change the bulb because it had been a long time since she had to do it.
While I was sitting in the chair I offered to do it. I'm mechanically inclined and the lamp housing and bulb were similar to other things I've fixed before.
In a about 3 minutes we had light again and this is what I found really interesting.
The hygenist said "It's so bright now, I can see so much more. I never realized how dim the other bulb was before"
My brain was spinning around this.
- How long had the bulb been deteriorating?
- How many people didn't get the best cleaning because of a dim bulb?
- If the bulb hadn't burnt out would I have had a less than adequate cleaning?
- What is the standard for testing the luminescence of dental chair lamp bulb?
- How many other jobs/industries have this same issue but don't realize it?
What's my take away from all this.
- Without a standard you can't tell when something begins to deteriorate
- If you can't see a problem you can't fix it
- Preventative maintenance should always be done...especially on CTQ (Critical to Quality) equipment
- Next time I clean the house make sure I have exceptional lighting when I do it and my wife has poor lighting when she checks my work.
