How to Choose a Commercial Safe: UL and Fire Ratings Explained

As a business owner in Burlington, protecting your company’s most valuable assets—cash, documents, records, and sensitive data—goes far beyond locking the front door at night. A properly chosen commercial safe provides reliable security against theft, fire, and other risks that could disrupt operations.

But not all safes are created equal. To make the best investment, it’s essential to understand the two key industry standards that define a safe’s performance: UL ratings and fire ratings.

At Action Lock & Key, we help businesses navigate these choices so they can invest with confidence. Below, we’ll explain what these ratings mean, why they matter, and how to match the right safe to your business needs.

Why UL and Fire Ratings Matter

A commercial safe isn’t just a box with a lock. Its construction, materials, and design go through rigorous testing to prove its ability to resist theft attempts or survive extreme heat.

Two ratings—set by Underwriters Laboratories (UL) and various fire-testing organizations—act as your guide to determine how much protection you’re actually getting.

• UL 687 Ratings tell you how resistant the safe is to burglary or unauthorized access.
• Fire Resistance Ratings (FRR) tell you how long the safe can withstand high temperatures while keeping contents protected.

Without these ratings, you’re left guessing. With them, you can make an informed decision that balances risk, cost, and peace of mind.

Understanding UL Ratings

Underwriters Laboratories (UL) is an independent testing agency recognized worldwide for safety and performance certifications. When it comes to safes, UL standard 687 ratings measure how well a safe resists professional break-in attempts using tools, torches, or explosives.

Here are the most common UL burglary ratings for safes:

• TL-15: The safe can resist a tool attack for at least 15 minutes.
• TL-30: Provides 30 minutes of protection against sophisticated hand tools and power tools.
• TL-30X6: Tested for 30 minutes on all six sides, ensuring no weak points in the design.
• TRTL-30X6: Offers 30 minutes of resistance against both tools and torches on all six sides.

Why this matters: If your business handles high amounts of cash, jewelry, or confidential information, a higher UL rating may be essential. Banks and financial institutions, for example, almost always require a safe with a UL-rating of TL-30×6 or TRTL-30×6. For retail, restaurants, or offices, a TL-15 or TL-30 safe often strikes the right balance between cost and protection.

Understanding Fire Ratings

The second half of the equation is fire protection. A fire-rated safe is tested to ensure it can maintain an internal temperature low enough to protect paper, digital media, or other valuables for a certain period.

Here’s what the ratings generally mean:

• 30-Minute Rating: Keeps the interior below 350°F for half an hour at external temperatures up to 1,550°F.
• 1-Hour Rating: Protects contents for 60 minutes—ideal for most offices.
• 2-Hour Rating: Provides longer protection, suitable for businesses storing irreplaceable documents or sensitive data.

It’s important to note that fire safes are tested against heat and, in many cases, drops (to simulate floors collapsing during a fire). However, fire resistance does not automatically mean burglary resistance—many fire safes are not UL-rated for theft protection.

Matching the Safe to Your Business Needs

Every business in Burlington, has different priorities. The right safe depends on the specific risks you’re trying to guard against. Here are a few common scenarios:

• Retail Stores and Restaurants: Daily cash deposits call for a safe with at least a TL-15 rating, often combined with a drop slot or depository feature. A one-hour fire rating adds an extra layer of protection.
• Offices and Professional Firms: Protecting contracts, tax records, and sensitive client files often means prioritizing fire protection. A 1–2 hour fire rating is ideal, though a moderate UL burglary rating may also be beneficial.
• Healthcare or Legal Practices: Confidential records may require safes that meet both burglary resistance and long fire protection standards.
• Jewelry Stores or High-Value Businesses: A TRTL-30X6 safe provides the highest level of burglary resistance, often necessary for insurance compliance.

Other Commercial Safe Features to Consider

Beyond UL and fire ratings, you’ll want to think about:

• Size and Capacity: Make sure the safe fits both your space and your storage needs.
• Locking Mechanism: Options include combination locks, electronic keypads, or even biometric access.
• Anchoring Options: Bolting your safe to the floor adds another layer of security.
• Insurance Requirements: Some policies mandate specific ratings to validate coverage.
