Copper wires are often melted by using propane blow torches at the cut ends to prevent fraying and ease assembly thru trunking holes etc. Blowtorches are also used to heat seal plastic tubing to protect electrical insulation or to bind several cores together. I will be surprised management - at least at the supervisory level - does not know this, and that inevitably, they will be used. So really shameful to detach themsleves from blame when trouble occurs. Another example of cowardly Singtel mgmt Sinkie behaviour. Not standing behind your men.
