Construction and Workplace Safety in Thailand: Accident Prevention and Emergency Response

Protecting Construction Workers in Thailand: Accident Prevention, First Aid, CPR and AED Preparedness

Thailand’s construction industry remains a high-risk working environment, with hazards ranging from falls and falling objects to structural collapses, electrical injuries, severe bleeding and cardiac emergencies. For construction companies, workplace safety must extend beyond personal protective equipment and accident prevention to include effective emergency response.

In an article published on September 22, 2023, Bangkok First Aid examined figures relating to occupational accidents in Thailand in 2021. The reported data identified building construction as the occupational category with the highest reported risk in the comparison, accounting for 4,516 injuries or fatalities and a reported risk figure of 5.77%.

The figures are historical and should be interpreted in the context of the original report. However, the broader safety concern remains relevant. In June 2024, Thailand’s Ministry of Labour reported that 81,509 employees experienced work-related injury or illness in 2023, down from 94,906 in 2019. The Ministry also identified residential building construction as the business category with the highest number of reported cases.

For construction companies, contractors, site managers and health and safety professionals, these figures reinforce an essential message: preventing accidents is the priority, but being prepared to respond when an accident occurs can also save lives.

1. Thailand’s Construction Industry: Economic Development and Human Risk

Construction is essential to Thailand’s economic development. Residential buildings, commercial towers, factories, hotels, roads, bridges and public infrastructure support businesses and communities throughout the country.

However, construction sites combine multiple hazards within a constantly changing environment. Workers may operate at height, work close to heavy machinery, handle electrical systems, lift heavy materials and perform tasks in confined or poorly ventilated spaces.

Unlike a conventional office, a construction site can change significantly from one day to the next. A floor opening may appear as work progresses, temporary supports may be installed or removed, and different subcontractors may work simultaneously in the same area.

A safe site therefore requires continuous risk assessment, effective supervision, appropriate protective equipment and a workforce prepared to respond to emergencies.

What do the statistics tell us?

Thailand’s Ministry of Labour reported a decline in the overall number of employees experiencing work-related injuries or illnesses between 2019 and 2023. Nevertheless, residential building construction remained a major concern in the Ministry’s reporting.

These national figures should not be confused with a construction-specific fatality rate. They cover broader categories of occupational injury and illness, and the number of incidents alone does not tell us the precise risk per worker or per hour worked.

The practical lesson is that construction companies need to examine their own accident records, near misses, site conditions and emergency response capabilities, rather than relying solely on national averages.

2. A Real Construction Accident in Bangkok: The One Bangkok Site Collapse

A documented incident demonstrates how quickly a construction accident can become a life-threatening emergency.

On February 17, 2022, a structural support system used during concrete pouring collapsed at the One Bangkok construction project on Rama IV Road in Bangkok. According to Thailand’s Ministry of Labour, three workers died and three others were injured.

The incident prompted government attention to the assistance and compensation owed to affected workers and their families.

This was not a minor workplace incident. A structural failure during a construction operation caused multiple casualties, illustrating why site safety, structural controls, competent supervision and emergency planning must work together.

What can construction companies learn from this incident?

First, prevention must come before emergency response. Structural supports, temporary works, lifting operations and concrete-pouring activities require appropriate engineering controls, inspection and competent supervision.

Second, a major incident can produce several casualties simultaneously. A site may need to manage injured workers, secure the surrounding area, coordinate emergency services and prevent additional injuries at the same time.

Third, emergency preparedness must be realistic. Site teams should know who calls emergency services, who guides responders to the casualty, where first aid equipment is located and how to communicate the site’s access points.

Finally, first aid training cannot replace engineering controls or make an unsafe operation acceptable. It is an additional layer of protection that becomes essential when prevention fails.

3. The Most Dangerous Hazards on Construction Sites

Construction accidents can occur in many ways. The most important hazards depend on the project, its stage of development, the equipment in use and the conditions on site.

Falls from height

Falls from scaffolding, ladders, roofs, unfinished floors and elevated platforms can cause severe injuries or death.

The US Occupational Safety and Health Administration identifies falls as a leading cause of fatalities in construction and highlights hazards such as unprotected edges, floor openings, improperly constructed scaffolds and unsafe ladder use.

Although US statistics and regulations should not be treated as Thai statistics or Thai law, the underlying hazards are relevant to construction risk assessment worldwide.

Source: OSHA — Construction Falls.

Possible injuries include:

• Traumatic brain injuries and concussion.

• Spinal injuries and possible paralysis.

• Fractures, including fractures of the pelvis, legs, arms and ribs.

• Internal bleeding and damage to internal organs.

• Severe external bleeding and shock.

Safety measures: use suitable collective fall protection, guardrails, secured floor openings, inspected scaffolding, appropriate fall-arrest systems and task-specific training. Personal protective equipment should be selected and used according to the assessed risk and applicable Thai requirements.

Falling objects and struck-by incidents

Tools, construction materials, equipment and debris can fall from elevated work areas or be displaced during lifting operations.

Workers may also be struck by moving vehicles, cranes, excavators or other machinery.

Possible consequences include head trauma, crush injuries, fractures, amputations and life-threatening bleeding.

Safety measures: establish exclusion zones, secure tools and materials, separate pedestrians from vehicles, use appropriate barriers and lifting controls, and ensure workers wear suitable protective equipment.

Structural and temporary-work failures

Construction frequently involves temporary structures, scaffolding, formwork, shoring and other support systems. Failure can expose workers to collapsing materials, falling debris and crushing forces.

Safety measures: ensure temporary works are designed, installed, inspected and altered only by competent personnel under appropriate controls. Stop work when instability or unexpected movement is identified.

Electrical injuries

Temporary power supplies, damaged cables, electrical tools and overhead power lines can expose workers to electric shock or electrocution.

Electricity can cause cardiac arrest, respiratory arrest, burns and secondary injuries if a worker falls after receiving a shock.

Safety measures: isolate electrical hazards, use suitable protection, inspect equipment, maintain safe distances from overhead lines and ensure only competent personnel perform electrical work.

Never touch a person who may still be in contact with a live electrical source. The power must be isolated safely before approaching the casualty.

Heavy machinery and crush injuries

Workers can become trapped between vehicles and structures, caught in moving machinery or injured during loading and unloading.

Crush injuries may cause severe damage to muscles, bones, blood vessels and internal organs. Serious complications can exist even when the external wound appears relatively small.

Safety measures: implement machine guarding, lockout procedures where required, vehicle segregation, reversing controls, safe lifting plans and clear communication between operators and ground personnel.

Manual handling and musculoskeletal injuries

Lifting heavy materials, carrying equipment, repetitive movements and awkward working positions can cause back injuries, muscle strains and joint problems.

Thailand’s Ministry of Labour also identified work-related musculoskeletal and skeletal disorders as a significant occupational health concern in its 2024 reporting.

Safety measures: assess manual handling tasks, use mechanical aids where appropriate, improve work positioning, provide task-specific training and address repetitive or excessive physical demands.

Heat stress and dehydration

Thailand’s hot and humid climate can make construction work physically demanding, especially when workers perform heavy tasks outdoors or wear protective clothing.

Heat-related illness can progress from heat cramps and exhaustion to heat stroke, a medical emergency that can cause permanent injury or death.

Warning signs may include weakness, dizziness, headache, nausea, unusual behaviour and collapse. Confusion, seizures or reduced consciousness in a heat-exposed worker should be treated as an emergency.

Safety measures: provide drinking water, suitable rest breaks, shade or cooling areas, gradual acclimatisation and work-rest arrangements adapted to the conditions and intensity of work.

Hazardous substances, dust and noise

Construction workers may be exposed to cement, silica-containing dust, solvents, welding fumes, asbestos in certain existing structures and excessive noise.

Some exposures cause immediate harm, such as chemical burns or eye injuries. Others may contribute to long-term respiratory disease, hearing loss or other occupational illness.

Safety measures: identify hazardous substances, use appropriate engineering controls and ventilation, provide suitable respiratory and other protective equipment, and follow the relevant safety data sheets and occupational health requirements.

4. What Happens When a Construction Accident Occurs?

When an accident happens, the first few minutes can be critical. However, an immediate response must be safe, organised and appropriate to the casualty’s condition.

A worker who falls from height may have spinal injuries. Someone struck by machinery may have internal bleeding. An electrical injury may trigger cardiac arrest. A deep wound can cause life-threatening blood loss.

The response should begin with scene safety, not an impulsive rush toward the injured person.

Step 1: Make the scene safe

Before approaching the casualty, identify immediate dangers such as:

• Moving machinery or vehicles.

• Unstable structures or falling debris.

• Electrical hazards.

• Fire, smoke or hazardous substances.

• Traffic and ongoing lifting operations.

Do not enter an unsafe area or expose yourself to the same hazard. Stop work and request assistance from the relevant site safety personnel when necessary.

Step 2: Activate the emergency response

Call Thailand’s appropriate emergency service. For emergency medical assistance, 1669 is Thailand’s emergency medical service number.

Give the dispatcher the exact site location, access gate, building or floor, nature of the incident, number of casualties and known hazards.

Construction sites can be difficult for outside responders to navigate. Assign someone, if safe, to meet the ambulance and guide the crew to the casualty.

Step 3: Assess the casualty

Once the scene is safe, check whether the person responds and whether they are breathing normally.

If the casualty is unresponsive and is not breathing normally, activate emergency medical assistance, begin CPR and obtain an AED as quickly as possible. Follow the AED’s voice prompts and current recognised resuscitation guidance.

If the person is conscious, assess the apparent injury, severe bleeding and other signs of deterioration without unnecessarily moving them.

Step 4: Provide appropriate first aid

The first aider should act within their training and available equipment.

• Severe bleeding: apply firm, direct pressure to the wound. Use an appropriate haemostatic dressing or tourniquet when indicated and when the first aider is trained to use it.

• Suspected spinal injury: minimise unnecessary movement and follow emergency dispatcher instructions. Do not move the casualty unless required to escape an immediate danger or provide essential lifesaving care.

• Burns: remove the person from the source of harm when safe and cool thermal burns with cool running water. Do not apply ice or creams to a serious burn.

• Heat-related illness: move the person to a cooler area if safe, initiate cooling and seek urgent medical assistance when severe symptoms are present.

• Cardiac arrest: start CPR, use an AED as soon as available and continue following the device’s prompts and dispatcher instructions.

Step 5: Monitor and hand over

Stay with the casualty when it is safe to do so. Monitor their breathing and responsiveness, provide reassurance and update emergency services if their condition changes.

When professional responders arrive, communicate what happened, the injuries observed, the first aid provided and any relevant changes in the casualty’s condition.

Good first aid is not about replacing emergency medical professionals. It is about providing appropriate immediate care while professional help is on the way.

5. Why First Aid, CPR and AED Training Matter in Construction

Construction companies need more than a first aid kit on a wall. Workers must understand how to recognise an emergency, call for help, protect themselves and provide appropriate care.

A structured First Aid CPR AED course helps employees develop practical skills that may be required during workplace emergencies.

First aid for traumatic injuries

Construction-specific training can address common workplace scenarios such as severe bleeding, burns, fractures, crush injuries, eye injuries and suspected spinal trauma.

Participants learn to assess the scene, recognise serious conditions, use available equipment and understand when emergency medical assistance is necessary.

CPR and AED for cardiac arrest

Cardiac arrest can occur at work, including in physically demanding environments. When a person is unresponsive and not breathing normally, immediate CPR and early AED use can improve the chance of survival.

An automated external defibrillator (AED) analyses the heart’s rhythm and advises whether a shock is indicated. The rescuer should follow the device’s instructions and continue CPR as directed.

Construction companies should consider whether AEDs are appropriate for their site, where they should be positioned, how they will be maintained and how quickly workers can access them.

Teamwork under pressure

A major incident may require several people to work together. One person can call emergency services while another brings the first aid equipment and AED, and a trained responder provides care.

Practical drills help employees understand their roles, communicate clearly and avoid confusion during a real emergency.

Training should be practical and relevant to the actual hazards, site layout, workforce and emergency arrangements.

6. A Real Worker Perspective: Why Prevention and Training Matter

An International Labour Organization study, High rise, low pay: Experiences of migrant women in the construction industry in Thailand, documented the safety concerns of migrant workers and the challenges faced on some construction sites.

One worker interviewed in Chiang Mai described the danger of working at height and the need for better protection:

“If possible I’d rather not go up heights. I would like the employer to buy safety equipment.”

— Migrant construction worker interviewed in the ILO study.

The same report includes an employer’s observation about workers at building edges:

“They can work at the edge of a building without anything.”

— Employer interviewed in Bangkok, quoted in the ILO study.

These statements are individual interview excerpts, not a description of every Thai construction site. They nevertheless illustrate an important point: safety depends on more than individual awareness. Employers must provide suitable controls, equipment, instruction and supervision, while workers need the knowledge and authority to raise concerns and stop unsafe work.

The ILO study also discusses challenges involving temporary work, limited training and the availability of protective equipment on some sites.

The lesson is not to blame workers for accidents. It is to build a system in which unsafe conditions are identified early, protective measures are provided and emergency response is properly organised.

7. How Construction Companies Can Improve Workplace Safety

A comprehensive safety programme should combine prevention, preparation, response and continuous improvement.

Conduct task-specific risk assessments

Assess the hazards associated with each activity, including working at height, lifting operations, excavation, electrical work, concrete pouring and machinery use.

Review the assessment when the work changes, a new contractor arrives or an incident reveals a previously unrecognised hazard.

Implement a clear site emergency plan

Every site should have a practical plan that explains:

• How to raise the alarm and contact emergency services.

• The exact site address and emergency access points.

• Who coordinates the initial response.

• Where first aid kits and AEDs are located.

• How casualties will be reached and handed over.

• How multiple casualties and site evacuation will be managed.

The plan should be communicated to employees, contractors and relevant visitors.

Provide appropriate first aid equipment

First aid supplies should reflect the actual hazards and size of the site. Equipment should be accessible, clearly identified, checked regularly and replenished after use.

Depending on the risk assessment, provisions may include dressings, gloves, eye irrigation supplies, burn care materials and other appropriate first aid items.

Equipment alone is not enough: workers must know where it is and how to use it safely.

Train employees and refresh practical skills

Construction companies should identify the people who require first aid training and ensure that training remains appropriate to their responsibilities.

Training should cover emergency scene assessment, severe bleeding, CPR, AED use, burns, suspected fractures, heat-related illness and the site’s emergency procedures, as relevant to the course and risk assessment.

Refresher practice and scenario-based exercises help teams retain skills and identify gaps in their response.

Encourage incident and near-miss reporting

A near miss can reveal a hazard before somebody is injured. Workers should be encouraged to report unsafe scaffolding, damaged equipment, unsecured materials, exposed cables and other concerns without fear of inappropriate retaliation.

Managers should investigate reports, implement corrective actions and communicate what has changed.

Coordinate contractors and subcontractors

Construction projects often involve several companies working simultaneously. Site owners, principal contractors and subcontractors should establish clear responsibilities for risk controls, emergency arrangements, inductions and communication.

A safety system is only effective when the people working on the site understand it and follow it.

8. Construction Safety and Legal Responsibilities in Thailand

Employers and contractors should ensure their safety arrangements comply with the Thai legislation and regulations applicable to their project.

The Occupational Safety, Health and Environment Act B.E. 2554 (2011) provides a key part of Thailand’s occupational safety framework. Construction-specific requirements also exist, including the Ministerial Regulation on Standards for Occupational Health, Safety, and Environment Management in Construction Work B.E. 2564 (2021).

The precise obligations depend on the project, the parties involved and the applicable legal provisions. Companies should consult the Department of Labour Protection and Welfare or qualified Thai occupational safety and legal professionals to confirm current requirements.

Official reference: Thailand’s Ministry of Labour.

Legal compliance should be the minimum standard, not the final objective. A company may need additional controls to address its particular equipment, site conditions, workforce and emergency response times.

Effective occupational safety combines legal compliance, hazard prevention, competent supervision, suitable equipment and trained emergency responders.

9. A Practical Construction-Site Emergency Checklist

Construction managers can use this checklist during safety reviews and site inductions.

1. Risk assessment: Are hazards assessed for the current stage of construction?

2. Fall protection: Are edges, openings, scaffolds and elevated work areas properly protected?

3. Machinery: Are vehicle routes, exclusion zones and machine safety procedures clear?

4. Electrical safety: Are electrical hazards controlled and equipment inspected?

5. First aid: Are suitable first aid supplies available and accessible?

6. Trained responders: Are designated first aiders available in accordance with applicable requirements and site risks?

7. CPR and AED: Do relevant employees know how to activate emergency help, perform CPR and use an AED?

8. Emergency contact: Is the emergency number 1669 known to the site team?

9. Site access: Can ambulance crews quickly identify the correct gate, building and casualty location?

10. Heat management: Are drinking water, cooling and appropriate rest arrangements available?

11. Communication: Can workers report hazards and near misses effectively?

12. Drills and reviews: Are emergency procedures practised, evaluated and improved?

NOTE: Use the checklist as a starting point and adapt it to the site’s specific risk assessment and legal obligations.
