Sadly an example of why compentency based training was introduced before being allowed near machinery.

It that was me on the trip I would be recommending a stop work and attend a education session (in swahili if necessary) then a clean up before a power up.
The mortality rate in that area of our world is bad enough without adding to it by introducing additional based machine risks.

Just out of interest what were the recommendations and conclusions resulting from the visit?
