INTRODUCTION

Roof safety is of utmost importance for those involved in construction or maintenance work at heights. Lifelines and guardrails are two widely used options to protect workers in such scenarios. In this comprehensive guide, we'll evaluate the pros and cons of two popular fall protection systems, assisting you in making an informed choice between lifelines and guardrails. Whether you're a construction manager, a facilities maintenance professional, or a safety professional considering safety systems for your roof, this guide is designed to help you decide which solution best suits your specific needs, while prioritizing fall protection.

Lifelines, often known as fall arrest or fall restraint systems, offer versatility and mobility, allowing workers to move freely while remaining secure. They can be customized to fit various applications. However, installation can be complex, and worker training is essential. On the other hand, guardrails are simple to install and require minimal maintenance. They provide continuous protection but may limit workers' mobility to designated areas. Guardrails are generally more cost-effective in the long run.

Primary Factor- Hierarchy of Fall Protection:

To understand the choice between lifelines and guardrails, the primary factor which influences is a 4-step process designed to help you understand what control measures should be in place to either eliminate or reduce fall hazards.  These follow the easy-to-apply principles of avoiding, preventing, and minimizing supported by appropriate training. Before you undertake any work at height task, you should ask yourself if working at height really is necessary.  If it is then you need to take steps to ensure the work can be carried out safely. 

STEP 1 – AVOID WORKING AT HEIGHT

• The primary focus should always be on eliminating risks and reevaluating working practices to minimize the necessity of working at heights.
• This goal can be accomplished by completely eradicating the need to work at height. For instance, consider siting air conditioning units at ground level instead of on a roof or adopting alternative working methods, such as using a reach and wash system for window cleaning instead of relying on ladders. Implementing these straightforward changes can eliminate the requirement for working at heights.

Step 2 - PREVENT FALLS USING COLLECTIVE EQUIPMENT

• When it comes to tasks that involve working at heights, opting for collective measures like guarded platforms or edge protection - guardrails becomes Important. These solutions not only shield individuals from potential hazards but also serve as an effective deterrent against falls.
• The preference for these options is rooted in their ability to safeguard everyone present on a roof or in a hazardous environment. Unlike individual fall protection systems, collective measures don't hinge on precise user adherence, demanding minimal training and upkeep. This makes them an optimal choice, particularly when consistent access to a roof or work area is necessary, such as during routine maintenance of plant and equipment.

Step 3 - PREVENT FALLS USING PERSONAL PROTECTIVE EQUIPMENT

• Personal Protective Equipment (PPE) takes center stage as the final line of defence. Commonly known as fall restraint or work restraint systems, these setups consist of an anchor point and a fixed-length lanyard. The primary goal is to grant users mobility within a designated area while preventing access to potential fall risks or hazards. This method becomes indispensable when collective safety measures aren't feasible, especially during routine roof repairs, gutter maintenance, or when working in proximity to fragile, unprotected roof lights.
• Despite its focus on restraint, it's imperative that these systems adhere to stringent design standards and undergo testing for current fall arrest loads. This ensures protection even in cases of misuse, such as employing a lanyard that's too long to effectively restrain the user from a potential fall risk.

Step 4 - MINIMISE DISTANCE USING PERSONAL PROTECTIVE EQUIPMENT

• If all options to prevent a fall are not possible, then you should try to mitigate the consequences of a fall. In other words, arrest a falling person before they hit the ground or an object.  This should only be used as a last resort when the first 3 safer steps have been ruled out and by those trained to use the equipment.
• These types of fall arrest systems generally consist of an anchor point, lanyard, and a full body harness and allow the worker to move freely around a roof or where there is a fall potential. If the user falls, the system absorbs the shock and force placed on the body and decelerates the worker’s fall over a short distance.
• Fall arrest systems are typically needed when work is carried out near the edges of a roof, where collective protection or restraint systems are not possible or practical.

Working at height is by its very nature dangerous.  So, before you undertake any task at height, ask yourself if the work at height is really necessary?  If it is then following our simple 4 step hierarchy of control will help you to put in place the correct control measures to protect workers and minimise the risks.

These few simple steps can go a long way to providing a safe working environment.

And don’t forget, your duty of care doesn’t end with following the hierarchy and specifying the correct system. You also need to ensure that any equipment is checked and inspected regularly to be sure it’s in good working order and safe to use.

Secondary Factor- Others:

Your choice between lifelines and guardrails should consider secondary factors such as roof type, project duration, worker training, and local regulations. We'll also present case studies showcasing real-world applications of these systems. Remember, regardless of your choice, safety should always be the top priority, with regular maintenance ensuring ongoing effectiveness.
