What does 'ready access' mean in reference to appliances?

'Ready access' when referenced in relation to appliances typically refers to the ability to reach the appliance directly without having to move any obstructions. This is important because it ensures that maintenance, servicing, or emergency intervention can be conducted efficiently and safely. Access without barriers allows technicians to quickly respond to any issues that may arise with the appliance, ensuring that it functions correctly and reducing potential hazards.

In this context, the other options suggest varying levels of difficulty or control in accessing the appliance. For instance, requiring tools to reach an appliance indicates a degree of complexity that goes against the principle of 'ready access.' Similarly, needing to move obstructions or requiring a key or controlled entry suggests a restricted or complicated access route, which is not aligned with the notion of ready access.
