SAMPLE RISK ASSESSMENT

为保护“大国工匠”的安全，以便继续生产各种大飞机，应该有必要

另外提醒一下，不能离太近

When drilling ensure you stand upright and that your head is not close to the moving parts of the machine (drill bit and chuck)

If you have long hair it may get caught in the moving parts of the machine
If the drill bit was to break it may hit you in the face
If the work piece is to come loose it may hit you in the face

If you are unsure of this please ask your teacher or technician

以上，不妥之处，敬请批评指正。
