I supplement with an assessment sheet.
In today’s training, there was no measure about the solvent which flowed onto the gutter.
When the inside of the gutter was seen, there was many cables.
Even if we put in a sand bag as it is, a cavity occurs and we cannot stop an out flow.
A lot of sand will be put in.
In order to prevent an outflow outside, it is required to stop an exit at least.
Please examine preparing sand near the exit of the gutter.
I have an experience in which the emulsion flowed out in Malaysia.
