Emergency Response: What to Do When an Accident Happens
An accident on a construction site can happen in seconds. A worker may fall, a machine may malfunction, or an electrical fault may cause serious injury.
In these moments, the first response matters. Panic, unsafe rescue attempts or delayed communication can put more people at risk.
Knowing what to do, what not to do and when to call for help can save lives.
When an Accident Happens
The first instinct may be to rush toward an injured worker. But before approaching, look at what caused the accident and whether the danger is still present.
A fallen worker may be near live electrical cables. A collapsed structure may still be unstable. Machinery may continue moving even after an operator releases the controls.
Remember: A rescue attempt must not create another casualty.
Make the Area Safe
Before helping, check whether the scene is safe to approach.
- Look for moving machinery, unstable structures, falling materials and electrical hazards.
- Keep other workers away from the danger zone.
- Alert the supervisor or responsible site personnel.
- Do not enter an unsafe excavation or confined space to attempt a rescue.
- Never touch someone who may still be in contact with electricity until the power source has been safely isolated.
Only trained and authorized personnel should isolate hazardous equipment or enter dangerous areas.
Raise the Alarm
Report the accident immediately. Do not assume someone else has already done it.
Clearly communicate:
- What happened: fall, electric shock, machinery incident or another emergency.
- Where it happened: building, floor, grid, work zone or another identifiable location.
- Who is affected: number of injured or missing workers, if known.
- What is needed: first aid, ambulance, fire response or specialist rescue.
Ask a specific person to call for emergency assistance when possible. This helps avoid confusion about who is responsible.
In Bangladesh, call 999 for emergency assistance when appropriate. Follow the site’s emergency plan and provide the exact location and access instructions.
Help Without Increasing the Danger
If the area is safe, provide only the assistance you are trained to give.
- If there is severe bleeding, apply firm, direct pressure with a suitable dressing.
- If someone is unresponsive and not breathing normally, call for emergency help, get an AED if available, and begin CPR if trained or follow the emergency dispatcher’s instructions.
- If a serious fall or impact is suspected, avoid moving the injured person unless remaining there presents an immediate danger or movement is necessary for lifesaving care.
- Do not attempt an untrained rescue from a trench, confined space or unstable structure.
- Reassure the injured worker and keep them as comfortable as possible while help arrives.
Do not put yourself or others at risk trying to help.
Guide Emergency Responders
When emergency responders arrive, help them reach the incident quickly.
- Send someone to guide them through the site entrance.
- Keep access roads and pathways clear.
- Share relevant information about the incident and any remaining hazards.
- Identify anyone who may still be missing or trapped, if known.
- Keep unnecessary bystanders away from the area.
Accurate information and clear access can help responders work more effectively.
After the Immediate Emergency
The response does not end when the injured worker receives help.
The responsible site team should secure the area, report the incident through the required procedure and preserve relevant information for investigation. Work should not restart in the affected area until it has been assessed and authorized as safe.
The purpose of an investigation is to understand what happened, identify contributing factors and prevent a similar incident. Workers should be encouraged to report hazards and near misses without fear of blame.

Every Second Matters
During an emergency, clear thinking and coordinated action matter more than rushing without a plan.
Know the alarm procedure. Know the site address. Know who to contact. And never attempt a rescue beyond your training.
The goal is not simply to respond to an accident. It is to protect everyone from further harm.
Quick Check
Before responding to an accident, ask:
☐ Is the area safe to approach?
☐ Has the alarm been raised?
☐ Have emergency services been contacted if needed?
☐ Can I help safely within my training?
☐ Is someone guiding responders to the location?
In an emergency, a quick response can save lives.
Stay calm, raise the alarm and make sure help can reach the injured person without putting others at risk.
STAY CALM. RAISE THE ALARM. GET HELP.
