Why Crash-Rated Barriers Are Essential for Modern Security Perimeters
In urban centers, suburban neighborhoods, or rural landscapes, no property is entirely safe from threats. Whether it's theft, vandalism, or arson, crimes against property cost U.S. owners over $17 billion annually. Another often overlooked danger is vehicle incursions—when cars, trucks, or other vehicles collide with buildings. Such incidents can lead to significant harm to both people and property. On average, a vehicle crashes into a structure somewhere in the U.S. about 60 times daily, regardless of whether it was intentional or accidental.
Crash-rated barriers are vital tools in preventing such accidents, managing traffic flow, and enhancing overall perimeter security. These barriers offer numerous advantages, from protecting pedestrians to safeguarding valuable assets. Let’s delve deeper into the significance of these devices to understand how TYMETAL Corp’s crash barriers can help fortify your property.
The Importance of Crash-Rated Barriers
Crash-rated barriers play a crucial role in improving safety in various environments, especially those prone to vehicle intrusions or criminal activities. Even locations not typically targeted by terrorism can benefit from these barriers, ensuring pedestrian safety and regulating traffic flow.
These barriers can be deployed in numerous scenarios. Along major highways and roads, they are often installed permanently or semi-permanently to boost road safety, reducing the likelihood of vehicles straying off course or crossing into oncoming lanes. At construction sites, access roads, and other key areas, crash barriers serve as effective safeguards or traffic guides. Designed to absorb impact energy and redirect vehicles when necessary, these barriers protect both life and property.
Understanding the Role of Crash Barriers in Perimeter Security
Properly positioned crash barriers can prevent vehicle breaches and protect sensitive assets and infrastructure. Depending on the setting and specific security requirements, these barriers can also manage crowds and direct foot traffic. Crash barriers fulfill several functions to enhance perimeter security:
- Absorb crash impacts and minimize resulting damage.
- Comply with any relevant facility security regulations.
- Provide a checkpoint for guards to conduct inspections.
- Control traffic flow to reduce congestion.
- Slow speeding vehicles and manage crowds during events.
- Integrate with other security solutions for comprehensive risk management.
Types of Crash Barriers
With various crash barrier types available, properties of all kinds can find systems tailored to their unique needs. You can choose from manual or automatic crash-rated gates, fencing, beams, and bollards, which fall under general crash barrier categories.
Crash Tested Barriers
These barriers undergo independent testing and receive ratings indicating their stopping power and expected penetration post-impact.
Crash-Rated Barrier Ratings and Certifications
The threat of terrorist attacks involving vehicles ramming through barriers prompted the U.S. State Department to establish a crash barrier rating system.
U.S. State Department Ratings
You may encounter one of three K ratings, each assessing the barrier’s stopping ability based on vehicle speed and weight:
- K4: Halts a 15,000-pound vehicle moving at 30 mph.
- K8: Halts a 15,000-pound vehicle moving at 40 mph.
- K12: Halts a 15,000-pound vehicle moving at 50 mph.
ASTM Ratings
Following updates in 2003, the U.S. adopted stricter global standards. The American Society for Testing and Materials (ASTM) now certifies crash tests. These ratings measure penetration and speed for various vehicle types. Speed ratings cover small passenger cars (SC), full-size sedans (FS), pickup trucks (PU), medium-duty trucks (M), class 7 cabovers (C7), and heavy goods vehicles (H).
ASTM also issues P ratings for penetration in three categories:
- P1: Less than 3.3 feet.
- P2: 3.31 to 23 feet.
- P3: 23.1 to 98.4 feet.
For instance, an M50, P2 crash barrier can stop a medium-duty truck traveling at 50 mph with penetration ranging from 3.3 to 23 feet.
Engineered Crash Barriers
Instead of formal ASTM crash testing, manufacturers rely on past experiences and engineering principles to calculate anticipated crash test performance. This performance is then certified by a Professional Engineer. Any crash test rating not corresponding directly to the "as tested" product is considered engineered. For example, if a specific size product is manufactured differently, its rating would be considered engineered, requiring certification that it meets the same crash test rating.
Reinforced Crash Barriers
Reinforced crash barriers aren't crash-tested or crash-rated. They simply offer enhanced crash resistance compared to standard versions. For example, a manufacturer might add horizontal steel cables to a slide gate, securing them to support posts or fixed bollards when the gate is closed. While this setup provides extra crash protection, the exact level remains undefined.
Benefits of Using Crash-Rated Barriers
Protecting valuable assets and ensuring human safety are among the main advantages of crash-rated barriers. These essential perimeter security solutions help minimize property damage caused by vehicle intrusions and collisions.
Enhanced Security: Preventing Vehicular Attacks
Permanent installations like crash gates and beams, along with portable options like crash bollards, offer strong security options. Criminals and terrorists are often deterred by the presence of security barricades. These devices also provide impact protection in case of attempted breaches, making crash barriers a key component of robust perimeter security strategies.
Cost-Effective Perimeter Protection Solutions
At TYMETAL, we recognize our clients' diverse needs, including budgetary limitations. While crash-rated barriers involve an upfront cost, the returns are immeasurable. Consider the savings from injury prevention and asset protection. These barriers can also reduce liabilities, cutting down on accident-related expenses and repair costs after incidents.
Choosing the Right Crash-Rated Barrier
To maximize the benefits of installing a crash-rated barrier, selecting the right type is crucial. Every property and situation is unique. A comprehensive site assessment yields the best outcomes. Here's a closer look at the process:
Assess the Site
Evaluate the intended area, noting site conditions and expected boundaries. Pay attention to side roads, terrain, landscaping, and utilities. Natural deterrents like hills, swales, rocks, and trees should also be considered. Local regulations and expected threat levels must also be taken into account.
Perform a Threat Assessment
Understanding the site's vulnerabilities and potential risks is essential for choosing the right crash barrier. Identify areas most susceptible to vehicular attacks. Conduct motion studies to determine vehicle paths and note typical vehicle sizes and speeds.
Consider the Details
Decide whether you need a permanent solution like a gate or beam or something removable like crash bollards. Evaluate the opening and surrounding space to determine suitable system types. Use the threat assessment to determine the appropriate crash rating for maximum safety.
