Generally, for accident and damage prevention those labour safety rules are valid which are also binding on the techniques of boring, drilling, countersinking and reaming. The following points, however should be emphasized:
- Use only clean, undamaged and sharp tools.- Use hammers and punches that are in proper condition.
- Clamp workpieces securely and tightly. But never apply excessive pressure. This may damage the work.
- Drive in pins only when the component parts are securely clamped and cannot slip.
- When loosening a pinned joint, rest the workpiece on a suitable support which does not allow the components to slip.
- Put all measuring and testing means down at their proper places. Use pads, supports and the like, in order to protect them against impact, shock and corrosion.
- It is regarded as good workmanship to keep ones workplace tidy and in good order and always to place individual parts next to their matching components.
