The shared duties employers and workers carry, why risk assessment matters, and how the card scheme fits in.
Health and safety on site is built on shared responsibility set out in law. For revision, you need the broad shape of who must do what, rather than chapter-and-verse legal references.
Employers carry the larger share. They must, so far as is reasonably practicable, provide a safe workplace, safe systems of work, safe plant and equipment, and the information, instruction, training and supervision people need to work safely.
Workers also have legal duties. You must take reasonable care for your own safety and for anyone affected by what you do, cooperate with safety arrangements, and not misuse anything provided for safety.
Risk assessment is the practical engine behind those duties: identify the hazards in a task, decide who could be harmed and how, then put controls in place and check they work. The aim is to reduce risk, not just record it.
On construction sites the skills-certification card scheme supports this by giving evidence that people on site have the relevant health, safety and occupational competence for their role.
For real situations, follow the current HSE guidance and your site’s assessments and rules. Use this lesson to understand the principle: safety is a duty shared by everyone, driven by assessing and controlling risk.
