The basic ratings for security guard safety boots are a standardized series of codes, primarily from the European EN ISO 20345 standard, that denote specific levels of protection. These codes build upon each other, starting with SB (Safety Basic) for a 200-joule impact-resistant toe cap, and progressing to S1, S2, and S3 by adding features like anti-static properties, water resistance, and puncture-proof midsoles. Understanding these codes allows you to match the boot's capabilities directly to the hazards of your environment.
Choosing the right safety boot isn't about finding the highest rating; it's about precisely matching the boot's certified features—like puncture resistance (P) or water resistance (S3)—to the specific risks you face on patrol.
Decoding the Safety Ratings: The "S" System
The most common rating system you will encounter is the European "S" classification from the EN ISO 20345 standard. Each level incorporates the features of the levels below it, creating a clear hierarchy of protection.
The Baseline: SB (Safety Basic)
All legitimate safety footwear starts with the SB rating. This guarantees the most fundamental feature: a toe cap tested to withstand 200 joules of impact and 15 kilonewtons of compression force.
Foundational Protection: S1 and S1P
The S1 rating is a common choice for indoor security roles in dry environments. It includes all SB features plus:
- Anti-static properties
- Oil-resistant outsole
- Energy absorption in the heel region
An S1P boot provides all the benefits of S1 but adds a crucial feature: a puncture-resistant midsole. This protects the sole of your foot from sharp objects like nails or glass.
Adding Water Resistance: S2 and S3
The S2 rating is designed for outdoor work or environments where you may encounter moisture. It includes all the features of an S1 boot, but with a water-resistant upper.
The S3 rating is often considered the gold standard for all-purpose security work. It combines all the features of an S2 boot with the puncture-resistant midsole found in S1P. It is a complete package for unpredictable conditions.
Maximum Protection for Wet Environments: S4 and S5
S4 and S5 ratings are typically for fully moulded polymer or rubber boots (like wellingtons). They are completely leak-proof. The only difference is that S5 includes a puncture-resistant midsole and cleated outsole, while S4 does not. These are less common for general patrol but essential for sites with standing water or chemical hazards.
Understanding the Trade-offs and Standards
Simply knowing the codes is not enough. The standards behind them and the practical features of the boot are what determine its real-world effectiveness and your safety.
The European Standard (EN ISO 20345)
This is the standard that defines the "S" ratings. Its primary requirement is the 200-joule toe cap protection, which sets the baseline for what can be legally called "safety footwear" in regions that follow this standard.
The American Standard (ASTM F2413)
In the United States, you will see boots rated to ASTM standards. Instead of a single "S" code, the protections are listed individually on the boot's label. These include ratings for:
- I/75 (Impact Resistance)
- C/75 (Compression Resistance)
- PR (Puncture Resistance)
- EH (Electrical Hazard)
While the labeling is different, the protective principles are the same. A boot with I/75, C/75, and PR ratings offers similar protection to an S1P or S3 boot.
Comfort is Non-Negotiable
A rating cannot tell you how a boot feels after a 12-hour shift. For a security guard, who is constantly on their feet, comfort is a safety feature. Look for lightweight materials, shock-absorbing midsoles, and breathable linings to prevent fatigue, which can lead to accidents.
Making the Right Choice for Your Patrol
Select your footwear based on a clear assessment of your daily environment.
- If your primary focus is indoor corporate or retail security: An S1P boot provides the necessary toe and puncture protection while prioritizing comfort and slip resistance for smooth floors.
- If your primary focus is outdoor, all-weather patrols: An S3 boot is the most reliable choice, offering a full suite of protection against impact, punctures, and water.
- If your primary focus is a high-risk site (like construction or industrial): Demand an S3 or S5 rated boot and verify it meets any additional site-specific requirements, such as metatarsal (Mt) or electrical hazard (EH) protection.
Ultimately, your safety boots are a critical piece of personal protective equipment; choose them as the professional tool they are.
Summary Table:
| Rating | Key Protections & Features | Ideal Use Case |
|---|---|---|
| SB | Basic 200-joule impact-resistant toe cap | Minimum safety requirement |
| S1 / S1P | SB + anti-static, oil-resistant sole; S1P adds puncture-resistant midsole | Indoor security (dry environments) |
| S2 | S1 + water-resistant upper | Outdoor work with potential moisture |
| S3 | S2 + puncture-resistant midsole & cleated outsole | All-purpose, all-weather patrols (gold standard) |
| S4 / S5 | Fully leak-proof (rubber boots); S5 adds puncture-resistant midsole | High-risk sites with standing water/chemicals |
