Interview Questions for Ability to Work in High Places

My experience with fall protection equipment spans over 15 years, encompassing various industries including construction, telecommunications, and wind energy. I’ve worked extensively with a wide range of equipment, from basic harnesses and lanyards to more complex systems like self-retracting lifelines (SRLs), and fall arrest blocks. This experience includes not only using the equipment but also inspecting, maintaining, and training others on its proper use. For example, during a recent project involving the installation of communication towers, I was responsible for ensuring all crew members used and inspected their equipment daily, adhering strictly to OSHA standards. This included regularly checking for fraying, damage, and proper functioning of all components.

Fall protection systems are categorized into several types, each designed for different situations and work environments. The most common include:

• Guardrail Systems: These offer a physical barrier preventing falls, usually consisting of top rails, mid-rails, and toe boards.
• Personal Fall Arrest Systems (PFAS): These systems catch a worker after a fall has occurred. Key components include a harness, lanyard, and anchorage point. Sub-types include self-retracting lifelines (SRLs), shock-absorbing lanyards, and vertical lifelines.
• Positioning Systems: Designed to keep a worker in a safe position, preventing them from falling. Often used in situations requiring hands-free work at heights.
• Safety Nets: Provide a safety net below the work area, catching a worker in the event of a fall. They’re effective for larger areas and require careful planning and installation.
• Fall Restraint Systems: Prevent a worker from reaching the edge where a fall could occur. Usually involves a lanyard and a device attached to a fixed point, restricting movement.

The choice of system depends heavily on the specific job, the environment, and the potential fall distance.

The hierarchy of fall protection controls prioritizes eliminating the hazard entirely, followed by progressively less effective but still important measures. It’s a sequential approach:

1. Elimination: Completely removing the fall hazard. For instance, redesigning a building to eliminate the need for working at heights.
2. Substitution: Replacing a hazardous task with a safer one. Using a boom lift instead of climbing a ladder.
3. Engineering Controls: Implementing physical modifications to minimize fall risks, such as installing guardrails or platforms.
4. Administrative Controls: Implementing procedures and training to reduce risk, including job safety analysis (JSA) and ongoing training.
5. Personal Protective Equipment (PPE): Utilizing fall protection equipment such as harnesses, lanyards, and SRLs. This is the last resort after all other controls have been considered.

This hierarchy ensures that the safest possible measures are employed first, with PPE being a last line of defense.

A pre-task inspection is crucial for ensuring equipment safety and preventing accidents. My inspection process involves a detailed visual check of every component, following a checklist. This includes:

• Harness: Checking for tears, cuts, fraying, and proper functioning of buckles and straps. Inspecting stitching and ensuring all labels are legible.
• Lanyard/SRL: Checking for damage to the webbing, corrosion of metal parts, and proper functioning of the braking mechanism (in the case of SRLs). Confirming the lanyard’s length is appropriate for the work.
• Anchorage Point: Verifying the point’s structural integrity, ensuring it’s rated for the intended load, and that it’s securely attached.
• Connectors: Inspecting carabiners, snap hooks, and other connectors for damage, corrosion, and proper closure. Ensuring they are correctly attached and locked.

Any damaged or questionable equipment is immediately taken out of service and replaced. Documentation of the inspection is essential, often using a digital inspection system, to provide a record of equipment condition and maintenance.

Each fall protection system has limitations. Understanding these limitations is crucial for safe work practices:

• Guardrails: Ineffective if a worker falls over or under the guardrail.
• PFAS: The effectiveness of a PFAS relies on the proper selection and maintenance of equipment and a suitable anchorage point. A fall can still result in injuries due to the impact forces.
• Positioning Systems: Only effective for preventing falls, not arresting them if a failure occurs.
• Safety Nets: Require significant space below and can be ineffective if a worker falls outside the net’s area. They also pose a risk of impact injury upon contact.
• Fall Restraint Systems: Restrict movement, potentially hindering work efficiency and increasing the risk of other hazards if workers try to circumvent the limitations.

It is essential to understand the limitations and select the most appropriate system for the specific task and environment, always considering the potential for system failure and mitigating the impact.

I have extensive experience with harnesses and lanyards, having used them regularly in various high-altitude operations. My experience includes the proper selection of harnesses to fit different body types and work requirements, ensuring a secure and comfortable fit.

Following the rescue, a thorough investigation will be conducted to determine the root cause of the emergency and implement corrective actions to prevent future incidents. Accurate documentation of the entire event is crucial for learning from mistakes and making improvements in safety protocols.

Suspending work at heights is crucial for worker safety. Several weather conditions necessitate this action, primarily those that compromise stability and visibility. High winds, for instance, can destabilize scaffolding, ladders, and even the worker themselves, increasing the risk of falls. Heavy rain or snow significantly reduces traction, creating slippery surfaces and increasing the likelihood of slips and falls. Similarly, fog, heavy snow, or thunderstorms severely limit visibility, making it incredibly difficult to navigate the work area safely and accurately assess potential hazards. The presence of lightning also presents an immediate and extreme danger. In essence, any weather condition that significantly impacts visibility, structural stability, or worker safety mandates a work stoppage until conditions improve.

For example, during a project involving roof repairs, I once had to halt operations due to unexpectedly strong gusts of wind. The wind was so forceful that it threatened to blow the scaffolding off the building. The safety of the crew was my top priority, and we resumed only after the wind subsided and conditions were deemed safe.

Risk assessment and mitigation for working at heights is a systematic process. It starts with a thorough site survey to identify all potential hazards, including the height of the work area, surrounding obstructions, weather conditions, and the type of equipment to be used. Next, a detailed risk assessment is conducted considering these factors, assigning levels of risk to each hazard identified. Based on this assessment, appropriate control measures are implemented. These controls follow a hierarchy of risk control, prioritizing elimination, substitution, engineering controls, administrative controls, and finally, personal protective equipment (PPE).

For example, if a task requires working on a steep roof, we would likely use a fall arrest system instead of relying solely on a ladder. This is substituting a higher-risk method with a safer one. We would also implement engineering controls like scaffolding or edge protection to further minimize the risk of falls. This whole process involves not only following standard safety procedures but also adapting strategies based on the specific circumstances of the project.

My experience with access equipment is extensive. I’m proficient with various ladders (extension, step, and single), and I understand the critical importance of proper setup and securing techniques for each type.
