4.2 | Risk is assessed considering severity and likelihood of consequences | ||
4.3 | Control measures to minimise risk are implemented to level of responsibility or referred to appropriate person for further action | ||
4.4 | Containment procedures are applied where appropriate | ||
4.5 | Appropriate safety procedures are followed and personal protective equipment is used according to organisational procedures | ||
4.6 | Risk is eliminated where possible, and if not practical, actions are taken to control risk | ||
