Introduction: Dressing for Survival, Not Style
When it comes to working in freezing environments, comfort isn’t just a luxury — it’s a safety necessity. Whether you're a warehouse worker, delivery driver, or food processing technician in a walk-in freezer, cold exposure can quickly lead to reduced performance, frostbite, or even hypothermia. That’s why OSHA and NIOSH recommend a layered approach to PPE for workers in cold environments.
At eSafety Supplies, we specialize in OSHA-compliant cold storage apparel that keeps you warm, mobile, and safe — even when temperatures plunge below zero.
Why Layering Matters for Cold Storage Work
Layering helps:
- Trap body heat for insulation
- Control moisture from sweat or humidity
- Shield the skin from wind and sub-zero air
- Provide flexibility to adjust for changing conditions
Using a multi-layer system is one of the most effective ways to prevent cold stress — a risk OSHA classifies as a serious hazard under its General Duty Clause.

The Three Essential Layers (As Recommended by OSHA & NIOSH)
1. Base Layer: Moisture-Wicking First Defense
- Made from synthetic fibers (polyester, merino wool, or silk)
- Keeps sweat off the skin, which reduces cooling
- Avoid cotton — it retains moisture and speeds up heat loss
- Examples: thermal underwear, long-sleeve moisture-wicking shirts
2. Mid Layer: The Insulating Core
- Holds body heat with minimal bulk
- Common materials: fleece, wool, or quilted polyester
- Should be snug but not tight to allow air pockets to trap warmth
- Examples: fleece hoodies, insulated vests, padded liners
3. Outer Layer: Wind- and Waterproof Shell
- Protects against cold air, wind chill, and moisture
- Should be breathable to allow sweat to escape
- Features like taped seams, storm flaps, and thermal linings are ideal
- Examples: freezer jackets, bib overalls, insulated parkas

Real-World Layering Example for Freezer Workers
A worker in a -10°F food distribution center might wear:
- Base Layer: Merino wool thermal top and bottom
- Mid Layer: Fleece hoodie and quilted pants
- Outer Layer: Waterproof freezer parka and thermal bib overalls
- Accessories: Balaclava, insulated gloves, safety boots, wool socks
Tips for OSHA-Compliant Layering
- Layers must not restrict movement
- Ensure garments are flame-resistant if working around heat or sparks
- Conduct regular PPE checks for rips or worn insulation
- Use high-visibility outerwear in dark or traffic-prone areas
- Train workers to add/remove layers as needed for safety
Common Layering Mistakes to Avoid
- Wearing cotton as a base layer (it absorbs sweat)
- Over-layering, which leads to sweating and later chilling
- Using too-tight garments that reduce circulation
- Forgetting about the head, hands, and feet
Layering for Different Cold Storage Scenarios
| Environment | Base Layer | Mid Layer | Outer Layer | Key Accessories |
|---|---|---|---|---|
| -20°F Freezer | Merino wool | Padded fleece | Freezer parka & bibs | Gloves, boots, balaclava |
| 32°F Cooler | Synthetic top | Light fleece | Softshell jacket | Grip gloves, hat |
| Outdoor in Snow | Thermal poly | Quilted vest | Waterproof work coat | Face mask, insulated boots |
Training Workers on Layering Basics
Include layering guidance in your cold stress prevention program. Training should cover:
- How to build a proper outfit
- Signs that clothing isn’t working (shivering, numbness)
- When to change or dry layers
- OSHA expectations for PPE
Post signs in locker rooms or break rooms as visual reminders.
