Health, Safety and Legislation in Construction

Why a building site is a hazard

A construction site is one of the more dangerous places to work. People work at height, move heavy loads, use power tools, and share space with vehicles and hazardous materials. Because of this, safety is not left to luck: it is planned. A hazard is anything that could cause harm, and a risk is the chance that a hazard actually harms someone and how serious that would be. Before work starts, hazards are identified and controls are put in place through a risk assessment. The law sets clear duties on both employers and employees, and specific regulations cover the biggest dangers, such as falls from height, electricity, and hazardous substances. This module covers hazards and risks, control measures, protective equipment, safety signs, and the main legislation.

Safety and legislation words

Learn these terms before the controls are compared. They name the dangers and the ways they are managed.

Match each hazard to its control

A hazard against a risk

These two words are often mixed up, but they mean different things, and safety planning depends on telling them apart.

What should happen first?

Before any work starts on a new task, what should be done first?

• Carry out a risk assessment
• Start work quickly to save time
• Hand out equipment and hope for the best
• Wait to see if an accident happens

Control at the source, not just the person

When you meet a hazard, it is tempting to reach straight for protective equipment. But the strongest controls act on the hazard itself, before they rely on the worker. The best answer is to remove the hazard, or to control it at its source: fit a guard rail at the edge, extract dust where it is made, route a cable away from the walkway. Only after those controls are in place does personal protective equipment do its job, as the last line of defence for whatever risk is left. A hard hat is important, but it is not a substitute for a guard rail. So when a question asks for the best control, look first for one that acts at the source, and treat protective gear as the backstop, not the plan.

Pick the personal protective equipment

Select every item that is personal protective equipment worn by a worker.

• A hard hat
• Safety boots
• A high-visibility jacket
• A guard rail
• A warning sign

Order the steps of a risk assessment

Put the steps of a risk assessment in the order they are carried out.

• Identify the hazards
• Decide who might be harmed and how
• Evaluate the risks and choose control measures
• Record the findings and put the controls in place
• Review and update the assessment

Complete the safety facts

Something that could cause harm is a _____. The chance that it causes harm is the _____. Checking hazards and choosing controls before work starts is a _____. Safety gear worn by a worker is called _____.

Tap the two employer duties

Tap the TWO responsibilities that are duties of the employer rather than the employee.

• provide a safe place of work and training
• carry out risk assessments
• use the protective equipment that is provided
• follow the safe procedures given

A driver checking mirrors

Think of a careful driver. Before pulling out, they glance in the mirrors, check the blind spot, and only then move. Those few seconds of checking prevent the crash that cannot be undone afterwards. A construction site works the same way, because the checks come before the work: spotting what could go wrong, deciding how to stop it, and fixing the guard rail or routing the cable before anyone climbs or plugs in. Once someone has fallen or touched a live wire, no amount of care afterwards helps. Safety is something you build in first, not tidy up later, and every rule on site is really that one habit written down.

The site-safety run

Answer each one correctly to keep your lives. Choose the best answer.

Make the site safer

Read each situation and choose the best control.

• Workers are laying cables across a walkway where other people pass. What is the best control?
• A worker needs to reach a high point on the building. What should be in place before they climb?
• Hazardous dust is produced when cutting a material. Following the idea of controlling at the source, what is the best first step?

Build a safety sentence

Choose the word for each gap to complete one point about site safety.

Explain how a site is kept safe

A friend starting work experience on a building site thinks safety is just about wearing a hard hat. Using what you have learned, explain how a construction site is kept safe.

• Explain the difference between a hazard and a risk
• Explain what a risk assessment is and why it comes first
• Explain the duties of employers and of employees
• Explain the role of protective equipment and why it is not the only control
• Explain one relevant regulation, such as working at height
