🏗️ Common Safety Coordinator Interview Questions and Answers
1. Tell us about yourself and your safety background.
Answer:
“I have [X years] of safety experience in Singapore’s construction industry. I hold an Advanced Certificate in WSH, BCSS, Managing Work at Height, Confined Space, Fire Watchman, and First Aid with AED certifications. I have worked on MRT projects, HDB developments, and commercial buildings, handling site inspections, toolbox talks, PTW approvals, and accident reporting. My goal is always to achieve zero accident compliance while supporting productivity on site.”
2. What is the role of a Safety Coordinator in construction?
Answer:
“The role of a Safety Coordinator is to ensure compliance with the WSH Act and MOM regulations. I conduct daily inspections, highlight unsafe acts, monitor subcontractors, manage toolbox meetings, update records, and assist the Safety Officer or Project Manager in creating a safe working environment. I am also responsible for risk assessment, PTW monitoring, and accident investigation support.”
3. What do you know about the Workplace Safety and Health (WSH) Act in Singapore?
Answer:
“The WSH Act is the main law governing safety in Singapore workplaces. It requires employers, occupiers, and employees to take responsibility for safety. As a Safety Coordinator, my duty is to ensure that all construction activities are carried out with proper risk assessments, safe work procedures, and compliance with the MOM regulations and Codes of Practice.”
4. How do you handle unsafe behavior or non-compliance on site?
Answer:
“I believe in a two-step approach: first, educate and correct. If a worker is not wearing PPE or following procedure, I stop the unsafe act, explain the risks, and guide them to follow rules. If it is a serious violation, I stop the work immediately and escalate it to the Site Safety Manager. Safety must never be compromised.”
5. What are the most common hazards in Singapore construction sites?
- Working at Height – fall risks, scaffolds, ladders
- Lifting Operations – cranes, rigging, suspended loads
- Confined Space Entry – lack of oxygen, toxic gases
- Hot Works & Fire Hazards – welding, cutting, sparks
- Moving Machinery – forklifts, excavators, traffic
- Noise & Dust Exposure – long-term worker health risks
Answer:
“Hazards are everywhere in construction, but the key is identification and control. With proper RA, PTW, barricades, training, and supervision, most risks can be controlled to an acceptable level.”
6. What is Risk Assessment (RA) and why is it important?
Answer:
“Risk Assessment is a structured process of identifying hazards, evaluating risks, and implementing control measures. It is mandatory under the WSH Act. Without RA, workers may not understand the risks, which can lead to accidents. A proper RA also protects the company from legal issues and demonstrates compliance with MOM regulations.”
7. How do you ensure subcontractors follow safety rules?
Answer:
“I brief subcontractors during toolbox meetings, monitor them during site inspections, and ensure they submit proper Safe Work Procedures and PTWs. If they don’t comply, I issue reminders or stop work if necessary. Main-con holds ultimate responsibility, so we must keep all subcontractors aligned with the project’s safety standards.”
8. How do you prepare for MOM or WSH audit/inspection?
Answer:
- Review all safety documentation – RA, PTW, inspection records
- Conduct a site walkthrough for housekeeping & PPE compliance
- Ensure signages and barricades are in place
- Do a pre-audit briefing with site teams and close gaps
- Make sure all incident reporting systems are updated
9. What steps do you take if there is an accident on site?
Answer:
- Provide immediate first aid and call emergency services.
- Secure the accident area to prevent further injury.
- Report to Safety Manager / Project Manager.
- Assist in incident investigation.
- Implement corrective actions to prevent recurrence.
10. What is your experience with digital PTW (Permit to Work) systems?
Answer:
“I have hands-on experience with Hubble.Build, Novade, and BES-Shell. I manage online PTW applications, approvals, and closure. Digital PTW reduces paperwork, ensures real-time monitoring, and increases accountability.”
11. How do you conduct an effective toolbox meeting?
Answer:
- Prepare topics related to ongoing site activities
- Use simple language and visuals for better understanding
- Keep the session short (10–15 mins)
- Encourage workers to ask questions
- Record attendance for compliance
12. What do you do if productivity and safety come into conflict?
Answer:
“I always prioritize safety because accidents can cause greater delays and costs than following procedures. I explain to supervisors that safe work is efficient work. My focus is on finding a safe method to complete tasks without compromising project deadlines.”
13. What is the difference between a Safety Coordinator and a WSH Officer?
Answer:
- Safety Coordinator – supports the WSH Officer, monitors site safety, conducts toolbox talks, inspections, and ensures compliance on a daily basis.
- WSH Officer – legally registered with MOM, responsible for overall site safety, safety planning, audits, and compliance reporting.
14. How do you promote safety culture among workers?
Answer:
- Lead by example (always wear PPE).
- Conduct engaging toolbox talks.
- Recognize workers who follow safety rules.
- Report and correct unsafe behaviors immediately.
- Maintain good communication between Main-con and workers.
15. Why should we hire you as a Safety Coordinator?
Answer:
“You should hire me because I bring technical WSH knowledge, practical site experience, and the ability to work well with both management and workers. I am proactive, detail-oriented, and committed to ensuring compliance with MOM and project requirements. My goal is to help Main-con achieve zero accidents while supporting smooth project progress.”
