• Wear a PFD whenever working within two metres of open or deep water on site
• Brief all workers on the signs of cold water shock before starting waterside tasks
• Ensure rescue equipment including throw lines and lifebuoys is positioned at water edges
• Practice the rescue plan so all team members know their role in a water emergency
• If you fall in, try to float on your back and control your breathing for one minute
• Keep your head above water and resist the urge to swim until the shock passes
• Call for help immediately and grab any available flotation aid or fixed structure
• Pull casualties from the water horizontally to reduce the risk of cardiac complications
• Treat anyone rescued from cold water for hypothermia even if they appear alert
• Report all near misses involving water to improve controls and rescue readiness

• DON'T assume you can handle cold water because you are a strong swimmer
• DON'T work near open water without wearing a correctly fitted PFD
• DON'T jump into cold water to rescue someone unless you are trained and equipped
• DON'T ignore the risk in summer — UK waters are cold enough year-round for shock
• DON'T let a rescued person stand up or walk immediately — keep them horizontal
• DON'T remove wet clothing from a casualty in the open — wrap them in blankets instead
• DON'T give hot drinks to someone in severe hypothermia — rewarm gradually
• DON'T rely on swimming ability alone — cold water shock disables even expert swimmers
• DON'T work near water without checking rescue equipment is in place and accessible
• DON'T delay calling emergency services — cold water casualties deteriorate rapidly
