1. OBEY SAFETY SIGNS

construction poster obey

Warning, prohibition, mandatory, and other types of health and safety signs will be displayed on your construction site. People need to understand and obey them.

2. ALWAYS SIGN IN AND OUT

construction poster sign in

You need to know who is on your site at all times in case of emergencies, so people need to sign in and out on the construction site register.

3. BE CONSIDERATE

Being considerate isn't just a nice thing to do. Taking reasonable care of yourself and others is one of the health and safety responsibilities of employees.

4. FOLLOW INSTRUCTIONS

construction poster follow instructions

Employees must follow the instructions given to them on the construction site. Cooperating with employers is another one of the health and safety responsibilities of employees.

5. ATTEND SAFETY BRIEFINGS

construction poster attend safety briefings

Safety briefings and toolbox talks should be a daily occurrence on a construction site, and workers need to attend them to find out about hazards and risks and how to stay safe.

6. FOLLOW THE RAMS

RAMS stands for risk assessments and method statements, which are important documents in any workplace but especially for high-risk construction activities.

7. WEAR PPE AT ALL TIMES

construction poster wear ppe

PPE shouldn't be your only safety measure, but it is your last line of defence against a hazard. And on a construction site, it could be what protects you when all else fails. Do people need reminding why they should wear PPE on your sites? Here are 50 reasons to wear and use PPE.

8. NO HAT, NO BOOTS, NO VEST? NO JOB!

construction poster no job

The basic PPE you will need on a construction site is a hard hat, safety boots, and a high-vis vest. You shouldn't enter a construction site if you are not wearing these items.

9. OBEY SPEED LIMITS

construction poster obey speed limits

Each year, people are killed and seriously injured as a result of accidents involving vehicles and mobile plant on construction sites, and the faster you go, the more likely an accident is to happen. Remind drivers to slow down and obey the speed limits.

10. BANKSMAN NEEDED

construction poster banksman needed

The most dangerous part of traffic management on a construction site is during manoeuvring and reversing. During those moments, a competent banksman can assist the driver and help keep everyone safe.

11. CHECK EQUIPMENT BEFORE USE

construction poster check equipment

PUWER is a legal requirement that your equipment is safe to use. A simple pre-use PUWER inspection can help you notice when equipment needs repairing or replacing.

12. USE EQUIPMENT SAFELY

construction poster use equipment safely

Equipment doesn't just need to be safe; it also needs to be used safely. That means only using equipment you are trained and competent to use, and using the right tool for the job.

13. NEVER BLOCK FIRE ESCAPES

construction poster fire escapes

If an emergency happens on your construction site, people need to get out quickly; they won't have time to move stacks of materials or equipment that are in their way. Never block fire escapes.

14. HOT WORK PERMIT NEEDED

If you create a flame, heat, or spark in your work, you need a hot work permit to control the risk and prevent fires.

15. KNOW YOUR EVACUATION PLAN

construction poster evacuation plan

In an emergency, you don't have time to think or plan your escape. Any delay could prevent you from getting out at all. Before you start work in a new area, you should know how to evacuate to safety.

16. IDENTIFY YOUR CLOSEST EXIT

construction poster closest exit

The first step in your evacuation is getting to your nearest exit. You should have at least two exit options in case one gets blocked, but the closest one should be your first choice.

17. DON'T MESS ABOUT

construction poster dont mess about

It's good to have fun at work, but messing about like throwing things, play fighting, pranks, or tampering with equipment is dangerous and can be deadly on a construction site. Don't mess about.

18. KEEP WORK AREAS TIDY

construction poster keep work areas tidy

Slip and trip hazards are the cause of many falls on construction sites. And the cause of a slip or trip could be something small like a cable or waste packaging, but keeping your work area tidy is important because slips and trips are responsible for around 30% of workplace injuries in the UK.

19. BE AWARE

construction poster be aware

Construction sites are busy places. This poster reminds workers to be aware of their environment. The different activities, hazards, equipment and machinery around them could put them in danger.

20. STAY ALERT

construction poster stay alert

Machinery moves. Excavations get covered and uncovered. Ladders get put up and taken down. Things change on construction sites all the time, every day, every hour. You don't just need to be aware of your surroundings, but also stay alert to changes.

21. KEEP GATES LOCKED

construction poster keep gates locked

Construction site security is vital if you want to keep trespassers (including thieves, vandals, and children) off your building site.

22. NEVER LEAVE TOOLS UNATTENDED

construction poster never leave tools unattended

If you want to keep your tools safe from unauthorised use and your site less tempting for thieves, make sure you lock away tools in secure storage when they are not being used.

23. REPORT ACCIDENTS AND NEAR MISSES

construction poster report accidents and near misses

It's a legal requirement to report accidents at work, and it can also help you make changes to make your construction site safer. Reporting near misses can even help you stop accidents before they happen.

24. UNSURE? ASK!

construction poster ask

No one knows everything. Construction projects have a funny way of throwing up surprises you might not have expected, so if you are unsure if something is safe, or how to handle it safely, stop work and ask first. Your safety might depend on it.
