To identify if boots are ASTM approved, you must look for a specific tag or label sewn into the interior. This label is most commonly found on the inside of the tongue or along the inner lining of the boot and contains specific codes detailing its safety compliance.
The presence of an ASTM label is the only definitive proof of compliance. This label acts as a technical specification sheet, detailing the exact type and level of protection the footwear provides against specific workplace hazards.
Locating and Understanding the ASTM Label
The key to verifying your boot's safety rating is finding and correctly interpreting its permanent information tag. This is a non-removable label required by the ASTM F2413 standard.
Where to Look
The label is required to be part of the footwear itself. Check the interior of the boot, specifically on the inner side of the tongue or stitched onto the upper interior lining, often near the ankle.
The Standard Itself: ASTM F2413
This is the Standard Specification for Performance Requirements for Protective (Safety) Toe Cap Footwear. It establishes the minimum standards for design, performance, testing, and classification. If a boot meets these standards, the label will explicitly state ASTM F2413.
Decoding the Safety Rating Codes
Think of the ASTM label as a code that details the boot's specific capabilities. It is typically formatted in a three- or four-line structure.
Line 1: The Standard and Year
The first line identifies the standard and the year of its revision, for example, ASTM F2413-18. The "-18" indicates it was certified against the standard revised in 2018.
Line 2: Gender and Toe Protection
The second line is critical and details the primary protection. It will look like M I/75 C/75.
- M or F: Designates the gender (Male or Female) the boot was designed for.
- I/75: This indicates the Impact Resistance rating. A "75" rating means the toe box can withstand a 75 foot-pound impact.
- C/75: This is the Compression Resistance rating. A "75" rating means it can withstand a compressive load of 2,500 pounds.
Line 3 & 4: Specific Hazard Protection
Subsequent lines denote any additional protections the boot offers. These are crucial for matching the boot to your specific work environment.
- EH: Electrical Hazard protection. These boots are designed to impede the flow of electricity through the shoe to the ground, reducing the possibility of electrocution.
- PR: Puncture Resistance. This indicates a puncture-resistant plate is built into the sole to protect against sharp objects like nails.
- Mt: Metatarsal Guard. This shows the boot includes protection for the top of the foot (the metatarsal bones).
- SD: Static Dissipative. These boots are designed to reduce the buildup of static electricity, crucial for environments with sensitive electronics.
Common Pitfalls to Avoid
Simply knowing a boot has a "steel toe" is not enough for ensuring compliance or safety. The specifics of the ASTM rating are what truly matter.
"Safety Toe" vs. "ASTM Rated"
A boot can have a composite or steel toe cap but fail to meet the rigorous impact and compression testing required by ASTM. The official label is the only guarantee of performance.
Assuming All Protection is Included
Never assume a safety toe boot also provides electrical hazard or puncture protection. If the EH or PR codes are not present on the label, the boot does not offer that specific protection.
Ignoring the Year of Certification
While older boots may still be protective, standards are updated to reflect new materials and safety knowledge. An employer or job site may require boots that conform to a more recent version of the ASTM F2413 standard.
Making the Right Choice for Your Goal
Use the label to ensure the equipment you wear is perfectly matched to the hazards you face.
- If your primary focus is construction or heavy industry: Your boots must have I/75 and C/75 ratings, and you should strongly consider a PR (Puncture Resistance) rating.
- If your primary focus is work as an electrician: You must have a boot with an EH (Electrical Hazard) rating in addition to the base I/75 and C/75 toe protection.
- If your primary focus is handling sensitive electronics: A boot with an SD (Static Dissipative) rating is critical to prevent damage to components, and may or may not require a safety toe.
- If your primary focus is general warehousing or logistics: A standard I/75 C/75 rated boot provides the necessary protection against falling objects and rolling carts.
Understanding how to read your boot's ASTM label is the first step in taking direct control of your personal safety on the job.
