If you've not worked on site before, this test might seem a bit of a bind - what's the point? The answer is that when you work on site you are not just responsible for the health and safety of yourself but also of those working around you. You might ask, 'Why is this - surely I can't be expected to look after others I don't even know?' The law says that you have a duty of care, but beyond any legal requirement, it's also the right thing to do. Even if you don't set people to work, you still have to look out for others. It's part of the job. / Construction is still one of the most dangerous industries to work in. You might be thinking that nothing is likely to go wrong on site, but each year around 80,000 workers suffer an illness that they believe was caused or made worse by their work. That’s over 300 workers a day! Around 52,000 of these are cases of bad backs, damaged shoulders or similar injuries, 12,000 are due to stress, anxiety and depression and 3,000 are from breathing and lung problems. Although the fatal accident figures have generally improved over the last 20 years, construction workers are still dying from work-related causes. I'm sure we can all agree that even one death is one too many. By now you might be thinking, 'OK, but what can I do? I'm just one person.' By studying this book and by taking CITB's Health, safety and environment test, you are making a great start. Whether you're new on site or an experienced worker, CITB's revision materials and test will help you get the basic health, safety and environmental knowledge and skills so that you can stay safe on site, spot dangers and speak up when you see that things might be going wrong. CITB works with industry experts and construction workers to make sure that the Health, safety and environment test is up-to-date and fit for purpose. The test is always being reviewed and new question styles have been introduced. We all want to make sites safe places where no-one's health is harmed. CITB is here to help you do that. Working together, looking out for each other, we can raise health and safety standards and make a positive impact on our industry. Revd. Eur Ing Kevin Fear BSc(Hons), CEng, MICE, CMIHT, CMIOSH, Hon FaPS Health and Safety Strategy Lead CITB INTRODUCTION About this book This book has been created to help you revise for your Health, safety and environment test. It contains all of the content that is covered within the test through questions and answers or statements of information so that you can fully prepare for your test. The book also includes information about how to book your test, any special assistance that is available and other helpful topics. About the test The CITB Health, safety and environment test helps raise standards across the industry. It ensures that workers meet a minimum level of health, safety and environmental awareness before going on site. The test structure has been designed to enable you to demonstrate knowledge across the following key areas. Section A: Working environment Section D: High risk activities Section B: Occupational health Section E: Specialist Section C: Safety Section A: Working environment General responsibilities: what you and your employer need to do to ensure everyone is working safely on site. Accident reporting and recording: when, how and why accidents need to be reported and recorded. First aid and emergency procedures: what you should do in case of an emergency, and what your employer must make available. Personal protective equipment: why personal protective equipment (PPE) is important, why you should wear it and who is responsible for it. Environmental awareness and waste control: your responsibilities on site, how waste should be managed and how to conserve energy. Section B: Occupational health Dust and fumes (Respiratory hazards): how to work safely, protecting yourself and those around you from exposure to respiratory hazards. What health conditions may arise from exposure to dust and fumes. Noise and vibration: why it is important to minimise exposure to noise and vibration in the workplace. How you should protect yourself and those around you. Health and welfare: common health issues on site and how to avoid them. Providing welfare facilities and support on site. Awareness of mental health. Manual handling: why and how it is important to handle all loads using a safe system of work. What key areas you need to be aware of when handling loads. o INTRODUCTION Section C: Safety Safety signs: what types of safety sign you will see on a construction site, and what they are informing you of. Fire prevention and control: what you should do if you discover a fire, and which fire extinguishers should be used on what type of fire. Electrical safety, tools and equipment: how to work safely with different types of tools, and what you should do if the tools you are using have not been examined or are faulty. Section D: High risk activities Site transport and lifting operations: how careful planning can safely segregate pedestrian and traffic routes, traffic rules you need to be aware of and how to lift loads safely. Working at height: what types of equipment you will use for working at height, and how to use them correctly. Excavations and confined spaces: how to work safely in a confined space or excavation, and what you should do if exposed to certain hazards. Hazardous substances: how you can identify a hazardous substance, and what control measures should be in place to enable you to work safely. Section E: Specialist If you are preparing for a specialist test you will also be asked questions about your specialist activity. There are currently 12 specialist tests available, including supervisory; demolition; highway works; specialist work at height; lifts and escalators; tunnelling; plumbing (JIB); heating and plumbing services; pipefitting and welding; ductwork; refrigeration and air conditioning; services and facilities maintenance. How is the test structured? All tests last for 45 minutes and have 50 knowledge questions. What is a knowledge question? The knowledge questions cover 16 core areas (presented in Sections A-D of this book) that are included in all the tests. These questions are factual. For example, they will ask you to identify fire extinguishers and signs. There is an additional knowledge question bank for each specialist test. You do not need to have a detailed knowledge of the exact content of any regulations. However, you do need to show that you know what is required of you, the things you must do (or not do), and what to do in certain circumstances (for example, upon discovering an accident). Legislation in Northern Ireland and Scotland differs from that in the rest of the UK. For practical reasons, all candidates (including those in Northern Ireland and Scotland) will be tested on questions using legislation relevant to the remainder of the UK only. o INTRODUCTION There are four different styles of knowledge question that may be presented within your test. These are explained below. Multiple choice and multiple choice with images Multiple-choice questions are identified by this icon. A multiple-choice question will ask you to select one or more answers from a list of options. Some answer options may also contain images.

The question bank is developed by industry-recognised organisations and question writing experts alongside the health, safety and environment test question sub-committee. We also work closely with industry to ensure the content covered in the test is relevant and fit for purpose. Will the questions change? Health, safety and environment legislation, regulations and best practice will change from time to time, but CITB makes every effort to keep the test and the revision material up-to-date. You will not be tested on questions that are deemed to be no longer current. You will be tested on knowledge questions presented in the most up-to-date edition of the book. To revise effectively for the test you should use the latest edition. You can check which edition of the book you have at www.citb.co.uk/hsandetest or phone 0344 994 4488.

Visitors and workers must be given a site induction and authorised to enter site. Employers must provide information to workers about site rules, welfare facilities and emergency procedures. Workers should be provided with clean welfare facilities and information regarding hazards and risks at work. Everyone on site is responsible for the consideration of neighbours and members of the public. Employees should follow a safe system of work agreed with the employer. A safe system of work would include information such as the sequence of work, and any hazards associated with the task. The purpose of a risk assessment is to identify hazards and control risk. Risk assessments consider the likelihood of a hazard occurring and the seriousness of harm that could occur. A method statement will inform a worker of the safe way to carry out a task. If a task feels dangerous or unsafe, stop work and report it immediately. 1.01 The whole site has been issued with a prohibition notice.
