WHO PROTECT Physical Infrastructure: Preventing Drowning by Design

A swimming pool has a gate, but it no longer closes properly. A marina has lifebuoys, but no suitable point from which a person can climb out of the water. A drainage channel crosses a community route without a barrier. A household cistern is left unsecured.

None of these situations begins as a rescue emergency.

They begin as infrastructure problems.

The first strategy in the World Health Organization’s PROTECT technical package is Physical infrastructure that promotes safe interaction with water.

Its inclusion sends an important message: drowning prevention does not depend only on people making safer choices or rescuers responding quickly. The environments in which people live, work, travel and enjoy the water can either reduce exposure to danger or allow preventable hazards to remain.

This is the second article in our series examining WHO PROTECT.

Readers unfamiliar with the framework can begin with our introduction to the WHO PROTECT drowning prevention package.

What does WHO mean by physical infrastructure?

The WHO PROTECT technical package for policy-makers presents physical infrastructure as one of seven priority strategies for preventing drowning.

The strategy focuses on policies, laws and systems that support safer interaction with water. It includes infrastructure that controls access to hazards, reduces the likelihood of accidental entry and creates safer environments around water.

In practice, this may involve:

• Barriers around pools, wells and other accessible water hazards
• Secure covers for water-storage systems
• Safer crossings over rivers and drainage channels
• Protection around exposed waterfront edges
• Infrastructure that separates swimmers from vessel activity
• Safer access to and exit from the water
• Design that supports supervision and emergency response

The right control depends on the setting.

A hotel pool, domestic cistern, fishing harbour, public beach and flood-prone road do not present the same hazards. Each requires assessment against its local use, environment, legal requirements and available safety capability. The central principle is straightforward: prevent or reduce exposure to danger before an incident occurs.

Barriers can stop an emergency before it begins

Physical barriers are among the clearest examples of drowning-prevention infrastructure.

WHO’s drowning fact sheet and prevention guidance identifies controlling access to water hazards, including fencing pools and covering wells, as an established approach to drowning prevention.

This is particularly important for young children, who may reach water quickly and quietly.

Depending on applicable local requirements, recognised standards and a site-specific risk assessment, controls may include:

• Fencing that separates a pool from homes, accommodation or play areas
• Gates designed to close and latch securely
• Strong covers over wells, cisterns and water-storage containers
• Barriers around drainage channels and hazardous drops
• Guardrails beside exposed bridges, quays and waterfront routes
• Controlled access to pools outside supervised hours
• Separation between young children and accessible water

A warning sign tells someone that a hazard exists.

A well-designed barrier can help prevent them from reaching it.

Signs remain useful, but they should not be treated as a substitute for physical protection where controlling access is reasonably achievable.

Safer pools and domestic water storage

Swimming pools are common across Caribbean hotels, villas, schools, homes and recreational facilities. Supervision remains essential, particularly where children are present. Infrastructure should support that supervision rather than relying entirely on an adult maintaining uninterrupted attention.

A pool-safety review should consider:

• Whether the pool is separated from nearby accommodation and play areas
• Whether gates and access controls work as intended
• Whether children can climb over, pass through or bypass a barrier
• Whether furniture or other objects make the barrier easier to climb
• Whether the pool is accessible outside supervised hours
• Whether lighting and visibility support effective supervision
• Whether safe entry and exit points are available
• Whether rescue and emergency equipment can be reached quickly

The presence of a gate or fence does not automatically mean the hazard is controlled.

A damaged barrier, a gate that is permanently propped open or a latch that no longer works may create the appearance of safety without providing effective protection.

Domestic water storage also deserves attention.

Many Caribbean homes and communities depend on tanks, cisterns, wells and other storage systems. These are essential facilities, but unsecured openings can present a serious hazard.

Practical controls may include:

• Strong and securely fitted covers
• Openings that cannot easily be lifted by a child
• Controlled or locked access
• Barriers around larger installations
• Inspection after storms, cleaning or maintenance
• Prompt repair of damaged lids, gates and surrounding structures

Risk can increase during maintenance when a normal cover or barrier has been removed.

Temporary controls should therefore remain in place until the system has been made secure again.

Waterfronts, ports and marinas

People can enter the water accidentally from docks, quays, jetties, slips, gangways and vessel berths.

The likelihood may increase at night, during rain, when surfaces are wet, while people are carrying equipment or where alcohol is involved.

Depending on local law, recognised standards and a site-specific risk assessment, practical controls may include:

• Protection at identified high-risk edges
• Non-slip walking surfaces
• Suitable lighting
• Clearly marked changes in level
• Accessible ladders or other recovery points
• Lifebuoys, throw lines or other suitable rescue equipment
• Safe gangways and handholds
• Separation between pedestrians, vehicles and operating machinery
• Clear emergency access for responders
• Identified locations from which a casualty can be recovered

These examples are not universal WHO requirements. They are practical applications of the physical-infrastructure strategy that operators and authorities may consider against their own risks and obligations.

A marina may have rescue equipment available, but that equipment has limited value if it is obstructed, poorly marked or unknown to staff.

Similarly, a ladder should not be judged only by whether it exists. It must be positioned and maintained so that it can realistically assist someone in the water.

Designing safer beaches and swimming areas

The sea cannot be enclosed in the same way as a swimming pool, but infrastructure can still support safer beach use.

Depending on the beach and its management arrangements, this may include:

• Clearly identified public access routes
• Safer entry and exit points
• Designated swimming areas
• Separation between swimmers and vessel or personal-watercraft routes
• Lifeguard observation points
• Rescue-equipment locations
• Emergency access routes
• Public warning or communication systems
• Signs explaining site-specific hazards
• Shade and welfare arrangements for safety personnel

Infrastructure should reflect the actual hazards and use of the location.

A generic sign may not explain a local reef, current, sudden drop-off, difficult exit point or vessel channel. Rescue equipment positioned far from the main activity area may not be available when seconds matter.

The CMSA Water Safety Code encourages people to assess conditions, recognise local hazards and make safer decisions before entering the water.

Good infrastructure supports those decisions by making hazards, controlled areas and safer options easier to recognise.

Roads, bridges and drainage systems

Physical infrastructure can also influence drowning risk away from beaches and swimming pools. Roads may cross waterways. Drainage channels may run through populated areas. Floodwater can hide road edges, damaged surfaces and open drains.

The physical-infrastructure strategy may therefore support measures such as:

• Barriers around deep or fast-flowing drainage channels
• Guardrails at exposed crossings
• Safer pedestrian routes
• Improved bridge and roadside protection
• Designs that reduce uncontrolled access to waterways
• Infrastructure planned around known flood routes and runoff

Operational warning systems, evacuations and emergency flood response belong more directly within the final PROTECT strategy, Threat preparedness. Those issues will be examined separately later in this series.

The physical-infrastructure question is narrower: has the environment been designed and maintained to reduce avoidable exposure to water hazards?

Infrastructure only works when it is maintained

Installing a safety feature is only the beginning. Salt, sunlight, corrosion, storms, heavy public use and constrained maintenance budgets can quickly reduce the effectiveness of infrastructure in Caribbean conditions.

An effective management system should establish:

• Who owns the structure or equipment
• Who is responsible for inspection
• How frequently checks take place
• How defects are reported
• Who can authorise repairs
• What temporary controls apply while repairs are outstanding
• How incidents and near misses influence future design

A broken gate, damaged guardrail or unusable ladder should not remain unattended because several organisations assume someone else is responsible.

Clear ownership and maintenance responsibility are part of the safety control.

A five-question infrastructure check

Families, operators, schools, property managers and public bodies can begin with five questions.

1. Where could someone enter water unintentionally?

Look for open gates, unfenced pools, unsecured cisterns, exposed quay edges, wells, drains, unstable banks and poorly lit routes.

2. Who is most exposed?

Consider young children, older people, workers, visitors, people with disabilities and those using the location at night or during poor weather.

3. Can access be prevented or better controlled?

A barrier, secure cover, repaired gate or changed pedestrian route may reduce the hazard at its source.

4. Can someone get out of the water?

Check steps, ladders, handholds, lighting and casualty-recovery access. Entering the water may be easy while climbing out is extremely difficult.

5. Who confirms that the control still works?

Assign responsibility. Record defects and track corrective action until the hazard has been properly addressed.

CMSA’s role in supporting practical implementation

PROTECT is intended to support governments and policy-makers in strengthening drowning-prevention laws, policies and systems. CMSA’s complementary role is to help translate international drowning-prevention principles into practical Caribbean education, training, risk awareness and stakeholder cooperation.

CMSA’s work can support this strategy by:

• Promoting site-specific water-hazard awareness
• Connecting infrastructure decisions with supervision and rescue capability
• Supporting swimming and public water-safety education
• Developing lifeguarding, lifesaving and responder competence
• Encouraging organisations to learn from exercises, incidents and near misses
• Bringing operators, communities and public bodies together around practical safety improvements

CMSA does not replace the responsibilities of planning departments, building authorities, maritime administrations, property owners or other regulators. It can, however, contribute technical insight, education and training to help organisations understand how infrastructure, people and emergency arrangements work together.

Preventing the need for rescue

Physical infrastructure is not the most visible part of drowning prevention.

A secured cistern cover, repaired pool gate, protected drainage channel or accessible marina ladder may receive little public attention.

That is often the point. The most effective safety intervention may be the one that quietly prevents a person reaching danger in the first place.

CMSA welcomes constructive technical exchange and joint public-safety initiatives with authorities, schools, tourism and maritime operators, property managers and community organisations seeking to identify and reduce preventable water hazards across the Caribbean.
