How to Choose the Right Construction Net: Debris Netting vs. Personnel Safety Nets
Construction netting covers a range of products that look similar but serve very different purposes. Scaffold debris netting and personnel safety nets are each engineered for specific applications. Selecting the wrong one can create serious compliance exposure on your job site.
Choosing the wrong net isn't just a hassle. Using a debris net where a personnel safety net is required is an OSHA violation. Inspectors know the difference even if buyers sometimes don't.
This guide walks through the main types of construction netting we carry, what each one is designed to do, and how to make the right call for your specific application.
Debris Netting vs. Personnel Safety Netting: What You Need to Know
Before getting into specific types of nets, it helps to understand the fundamental split in construction netting.
Debris netting is designed to catch falling objects – tools, fasteners, construction materials, and other debris that could injure workers or pedestrians below.
Personnel safety netting is designed to catch people in the event of a fall from an elevated work area.
These are NOT interchangeable. They’re built to different standards, tested differently, and regulated differently under OSHA. A debris net is rated for debris containment. A personnel safety net is rated to absorb the impact of a falling person. Those are completely different load requirements.
The compliance bottom line:
OSHA 29 CFR 1926.502 governs fall protection requirements for construction. Personnel safety nets must meet ANSI/ASSP A10.11 standards. Debris nets fall under ANSI/ASSP A10.37. Using a debris net in place of a personnel safety net is a citable OSHA violation, even if the debris net looks similar or feels strong enough. If an inspector visits your site and finds workers in an area that requires a personnel safety net but only has debris netting, your company can be fined.
Knowing this difference, first decide whether your main purpose for the net is to contain debris or protect falling workers. Keep reading to find the right net within either of those categories.
Scaffold and Debris Nets
These nets are specifically for containing debris on construction sites. US Cargo Control offers two broad options – RocBloc nets or the WS-70 debris liner nets.
RocBloc Debris Nets:
The RocBloc is the primary scaffold and debris netting solution. It’s a heavy-duty HDPE debris-containment net designed to wrap around scaffolding or contain falling debris. It installs vertically around the perimeter of a structure or scaffold.
RocBloc nets consist of two layers – a polypropylene structural rope net and an attached fine-mesh fabric liner. The combination contains both large debris and smaller materials like fasteners.
Types of RocBloc Nets:
RocBloc 2K: 2,000 lb load capacity. The structural rope net has a ¼” diameter with a 2” mesh size.
RocBloc 5K: 5,000 lb load capacity. The structural rope net has a 3/8” diameter with a 2.5” mesh size.
If you are looking for a solution for large debris, the RocBloc is for you.
WS-70 Debris Liner:
The WS-70 debris liner is a polyethylene panel with a super fine 1/8” mesh size. If your job only requires containment of small items, like fasteners, hardware, or fine dust without needing the load-bearing component of the RocBloc, the WS-70 will get the job done.
Personnel Safety Nets
Personnel safety nets are fundamentally different from debris netting. Where debris nets are designed to catch falling objects, personnel safety nets are engineered to catch and arrest a falling person. They’re installed horizontally beneath elevated work areas.
Personnel safety nets are much stronger than debris nets – hence why debris nets cannot be used as personnel nets. Personnel nets have a WLL of over 17,000 lbs because they’re built to absorb the energy of a falling person.
When workers are properly harnessed, a personnel safety net effectively acts as additional debris containment, especially when paired with a debris liner. If you need both a personnel safety net and debris containment, consider a personnel safety net with a debris liner.
Custom Net Applications
US Cargo Control offers custom debris and personnel safety nets built to your specs. Generally, off-the-shelf sizes of debris and personnel safety nets get the job done. However, there are certain applications where custom sizing is necessary.
Bridge Debris Netting
Bridge construction projects have unique geometry and span requirements and often require custom sizing. Typically, bridge debris nets have a similar construction to the RocBloc nets with a debris liner attached, and they are custom-built to your specific application. You can request a bridge debris net on our website. Fill out the form and a product expert will be in touch to get you the net you need.
Truck Loading Nets
A truck loading net fills in the gap between the loading platform and the truck bed. It's designed to catch any cargo or personnel that can fall through the opening due to slippery conditions, uneven surfaces, or lack of stability. One side of the net is attached to the loading dock with snap hooks, and the other side attaches to the rub rails of a flatbed with flat hooks.
Like bridge debris nets, these nets need to be customized to your needs, so fill out the form and a product expert will reach out to help.
Stormwater System Drainage Nets
Protect the environment with drain pipe debris nets. Designed for placement at the end of outflow pipes, this drainage netting will catch waste and organic matter as it passes through the stormwater system or sewer overflow application. They are made from knotless N815 netting to resist water and abrasion and can be paired with a liner to entrap small debris.
These nets must be custom-built to your pipe size and mount type. Fill out our custom form, and a product expert will be in touch.
How to Choose: A Simple Decision Framework
Still not sure which net you need? Work through these questions:
1. What are you trying to protect against — falling objects or falling people?
Falling objects only → Debris netting (RocBloc)
Falling people → Personnel safety net
Both → Personnel safety net with debris liner
2. What's your application?
Scaffolding wrap → RocBloc 2K or 5K (with or without WS-70 liner)
Bridge or infrastructure project → Bridge debris netting, likely custom
Below an open floor deck or steel erection → Personnel safety net
3. What does your debris look like?
Large construction debris only → RocBloc without liner
Small fasteners, nails, fine dust → RocBloc with WS-70 liner

Frequently Asked Questions
Can I use a debris net instead of a personnel safety net? No. A debris net (including the RocBloc 2K and 5K) cannot legally substitute for a personnel safety net where fall protection is required. They're built and tested to different standards. If an OSHA inspector finds workers in an area requiring a personnel safety net and only debris netting is present, your company will be cited and fined.
What's the difference between the RocBloc 2K and 5K? The numbers refer to the load rating of the net. The 2K is appropriate for most standard scaffold debris containment applications. The 5K is used when higher load ratings are specified, typically on larger-scale projects or per the engineer's requirements.
Do I need the WS-70 debris liner? Add the WS-70 liner if you're working with small fasteners, nails, screws, or fine dust - anything that could pass through the 2-inch square openings of the base RocBloc net. If you're only dealing with larger debris, the base net alone is sufficient.
What if my job site has a non-standard size or shape? All our debris and safety nets are available in custom sizes. Fill out our custom netting request form, include your measurements and any engineer drawings, and our team will build to your specs. Bridge debris netting is almost always a custom order.
How do I know which net my engineer spec requires? Your engineer's spec sheet will typically reference a product standard (ANSI A10.11 for personnel nets, ANSI A10.37 for debris nets) and a load rating. If you have a spec sheet and need help matching it to a product, call our team at (866) 444-9990. We can help you read the spec and find the right net.
