?'What is the difference between 'hazard' and 'risk

A hazard is something that can cause harm, eg electricity, chemicals, working up a ladder, noise, a keyboard, a bully at work, stress.

A risk is the chance, high or low, that any hazard will actually cause somebody harm.

For example, working alone away from your office can be a hazard. The risk of personal danger may be high. Electric cabling is a hazard. If it has snagged on a sharp object, the exposed wiring places it in a 'high-risk' category.
