NFPA 70B Infrared (image) Scanning take?

[muchsnow]

I have an issue where facility maintenance is checking gear and boxes with an IR thermometer rather than IR Scanning, iaw NFPA 70B (and required training/records). Once told I needed to mind my own business, I think I need to hammer this home with substance before continuing any more work there. What would be the most politically correct and orderly reference dialog to present this in that might kind of present or pressure the issue a bit more?... They've been signing off a LOT of annuals for quite some time. I see an entire rebase required, with/once qualified tech is in play, too. Makes sense to me.

Probably not a real problem if they are building a database they can use to analyze trends.

While a scan might show up specific hot spots, it is not always inherently better at anticipating problems.

Neither tool is very good if they are not used on a regular/routine basis. I have seen many all but useless reports based on one time IR Scans by poor to mediocre technicians.

IR thermometer rather than IR Scanning,

Thermometer contact probes provide accurate temperatures for checking conductor insulation limits, per 110.14(C).

IR scanning only shows relative differences for possible investigation with probes.
