Questions Asked in Comfortable working at heights and in confined spaces Interview
Q 1. Describe your experience with fall protection systems.
Fall protection systems are crucial for preventing injuries from falls at height. My experience encompasses a wide range of systems, from simple harnesses and lanyards to more complex systems involving anchor points, lifelines, and fall arrestors. I’m proficient in selecting the appropriate system based on the specific work environment and task. For example, on a recent project involving roof repairs, we used a full-body harness with a self-retracting lifeline anchored to a structural beam, ensuring the worker remained tethered at all times. In another instance, working on a scaffolding system, we implemented a horizontal lifeline system to protect multiple workers simultaneously. I also have experience inspecting and maintaining these systems, ensuring they’re compliant with relevant safety regulations and in good working order.
My understanding includes the critical aspects of system selection such as considering the fall distance, potential impact forces, the worker’s weight and the structural integrity of the anchor points. I am also well versed in different types of anchor points including structural steel, concrete, and purpose built anchor systems.
Q 2. What are the different types of confined space permits?
Confined space permits are legally mandated documents authorizing entry into a confined space. The specific types vary depending on the jurisdiction and the level of risk involved, but generally include:
- Entry Permit: This is the most common type, allowing entry after a thorough risk assessment and implementation of control measures. It specifies the entry procedures, hazards, and emergency response plans.
- Hot Work Permit: Used when work involving heat or sparks (welding, cutting) is to be done in a confined space. This permit adds extra layers of safety measures to prevent fire or explosions.
- Emergency Entry Permit: Issued only in emergency situations where immediate entry is required to rescue someone or mitigate a serious hazard. It typically has less detailed pre-entry checks but prioritizes swift action.
Each permit is specific to the task and the confined space. It requires the signatures of authorized personnel, demonstrating accountability for the safety of those entering the space. In my experience, meticulous completion and adherence to these permits are non-negotiable, and form the cornerstone of confined space safety.
Q 3. Explain the hierarchy of hazard controls in confined spaces.
The hierarchy of hazard controls in confined spaces prioritizes eliminating hazards whenever possible, moving to less effective controls only when elimination is not feasible. It follows this order:
- Elimination: Removing the hazard entirely. For example, redesigning a process to eliminate the need to enter the confined space.
- Substitution: Replacing the hazardous substance or process with a safer alternative. Using robotic systems for inspections instead of human entry.
- Engineering Controls: Implementing physical changes to control the hazard. Installing ventilation systems to improve air quality.
- Administrative Controls: Implementing procedures and training to mitigate risk. Implementing strict entry protocols and regular monitoring of atmospheric conditions.
- Personal Protective Equipment (PPE): Providing workers with equipment to protect them from the hazard. Respiratory protection, fall protection, and protective clothing.
This hierarchy ensures that the most effective and safest control measures are prioritized. For instance, if a confined space contains toxic fumes, elimination (e.g., modifying the process) is ideal. If that’s impossible, engineering controls (ventilation) are the next best option, before relying on respirators (PPE) as the last resort.
Q 4. How do you assess the risks associated with working at heights?
Assessing risks associated with working at heights requires a systematic approach. I typically follow a process that involves:
- Identifying Hazards: This includes the height of the work, the type of surface, the presence of obstacles, weather conditions, and the potential consequences of a fall.
- Evaluating Risks: Assessing the likelihood and severity of a fall. This involves considering factors such as the worker’s experience, training, and the condition of the equipment.
- Implementing Control Measures: Based on the risk assessment, implementing appropriate fall protection systems, such as guardrails, safety nets, or personal fall arrest systems.
- Monitoring and Review: Regularly inspecting equipment and work practices to ensure that the implemented control measures are effective and appropriate.
For example, when assessing a roof work site, I’d consider the roof’s fragility, the presence of any obstacles, and the weather conditions. I’d ensure proper fall protection is in place, and that workers are adequately trained in its use. Regular inspections of anchors, lifelines and harnesses are also key aspects of my assessment process.
Q 5. What are the signs and symptoms of hypoxia and how do you address them?
Hypoxia is a condition where the body is deprived of sufficient oxygen. Signs and symptoms can range from subtle to severe, including:
- Mild Hypoxia: Shortness of breath, headache, dizziness, fatigue, nausea.
- Moderate Hypoxia: Increased heart rate, confusion, impaired judgment, cyanosis (bluish discoloration of the skin).
- Severe Hypoxia: Loss of consciousness, seizures, respiratory arrest, death.
Addressing hypoxia requires immediate action. The first step is to remove the individual from the oxygen-deficient environment. Then:
- Administer supplemental oxygen: Using an oxygen mask or cylinder.
- Provide CPR if necessary: If the individual is unresponsive and not breathing.
- Seek immediate medical attention: Hypoxia can have long-term consequences if not treated promptly.
In my experience, prompt recognition of hypoxia symptoms is paramount. Regular atmospheric monitoring within confined spaces is crucial to prevent this dangerous condition. Team members are trained to recognize the symptoms and respond effectively, while pre-entry atmospheric testing is always performed.

Q 8. Explain your understanding of atmospheric monitoring in confined spaces.
Atmospheric monitoring in confined spaces is crucial for worker safety. It involves systematically testing the air within an enclosed area to identify and quantify potentially hazardous substances before, during, and after entry. This prevents accidents caused by oxygen deficiency, toxic gases, flammable vapors, or lack of ventilation.
The process typically includes using gas detection equipment to measure oxygen levels (O2), flammable gases (LEL – Lower Explosive Limit), toxic gases (e.g., H2S – Hydrogen Sulfide, CO – Carbon Monoxide), and potentially other substances specific to the work environment. Regular monitoring is essential because atmospheric conditions can change rapidly within a confined space due to ongoing work or natural processes.
For example, during a pipeline inspection, we’d meticulously monitor for methane and hydrogen sulfide, both common in natural gas pipelines. Failure to do so could lead to explosions or worker fatalities.
Q 9. What are the different types of respiratory protection and when would you use each?
Respiratory protection is vital in confined spaces where atmospheric hazards exist. Several types exist, each suited to specific situations:
- Air-Purifying Respirators (APR): These use filters or cartridges to remove contaminants from the air. They are only suitable if the oxygen level is sufficient (at least 19.5%). Common examples include N95 masks for dust or particulate matter and respirators with cartridges for specific gases. I’d use an APR for working with sanding or grinding operations where dust is a primary concern, but only when oxygen levels are confirmed to be safe.
- Supplied-Air Respirators (SAR): These provide breathing air from a source outside the confined space, ensuring a continuous supply of clean air. SARs are essential when oxygen levels are low, or the atmosphere contains high concentrations of toxic gases. I would choose a SAR for working in a tank that might contain low oxygen and potentially toxic fumes.
- Self-Contained Breathing Apparatus (SCBA): This independent unit provides a limited supply of breathing air carried by the worker. It’s the most protective but has limited duration and requires proper training and fit-testing. SCBAs are critical for emergency situations or when working in severely hazardous environments where other forms of respiratory protection are inadequate. I would utilize an SCBA during entry into an area with unknown atmospheric conditions or a potential for immediate danger.
