What are Basic Safety Principles for Machine Safety? Basic Safety Principles are fundamental requirements for all safety systems. From Category B to 4, Basic Safety Principles are the first step in building reliable systems. Do you pay attention to Basic Safety Principles when designing your safety systems?

Let's have a look at some common Basic Safety Principles in the below diagram of a circuit. Here we can see protection of control circuit, de-energisation principle, protection against unexpected start-up, transient suppression and sequential switching. As you can see, the circuit above shows a common safety interlock system with some of the Basic Safety Principles highlighted. These have been explained below:
The above are some examples of Basic Safety Principles that are relevant for electrical systems. The full list can be found in Table D1 of AS 4024.1502-2006. Basic Safety Principles can also be found for mechanical, hydraulic and pneumatic systems in the Appendix sections of this standard as well.
