Winter operations demand long hours in freezing temperatures, blowing snow, and damp conditions. Without the right clothing and protective equipment, road crews can quickly face hypothermia, frostbite, and reduced mobility. Proper layering and winter-specific PPE allow workers to stay warm, dry, and safe while performing critical public works duties.
This article offers practical guidance on how to build an effective layering system, what PPE is necessary for winter conditions, and how supervisors can support field workers during cold weather operations.
Layering is more than just adding bulk. Each layer serves a specific purpose. When used correctly, a layering system keeps workers:
Warm but not overheated
Dry even during heavy exertion
Protected from wind, snow, and freezing rain
Able to move freely to operate equipment safely
A proper layering system must manage moisture, maintain insulation, and shield workers from harsh winter conditions.
The base layer sits next to the skin and pulls sweat away from the body. Sweat that remains trapped against the skin cools rapidly and increases the risk of hypothermia.
Recommended Materials
Synthetic fabrics like polyester
Merino wool for warmth and odor control
Avoid
Cotton, since it absorbs moisture and dries slowly
Tips
Choose long-sleeve tops and full-length bottoms
Keep a spare set of base layers in the vehicle for mid-shift changes
The mid layer retains body heat. The thickness depends on the temperature, crew exertion level, and wind conditions.
Common Options
Fleece pullovers
Wool sweaters
Insulated vests or jackets
Key Considerations
Add more insulation for low-activity work
Reduce insulation when shoveling or performing heavy labor
The outer layer protects against wind, snow, sleet, and freezing rain. This layer must be both weatherproof and durable.
Recommended Features
Waterproof or water-resistant material
Windproof construction
Breathable fabric to allow sweat vapor to escape
High-visibility colors with reflective striping for roadway safety
Examples
High-visibility winter jackets
Waterproof bibs
Shell pants with sealed seams
Use insulated winter liners under hard hats.
Avoid exposing skin in extreme cold.
Choose face shields or balaclavas when wind chills are severe.
Hands lose heat quickly. Workers should have:
Insulated work gloves for cold tasks
Waterproof gloves for wet conditions
Dexterity gloves for equipment operation
Encourage workers to carry at least two pairs of gloves to rotate as they get wet.
Feet are especially vulnerable to cold stress.
Recommended:
Waterproof, insulated work boots with slip-resistant soles
Wool or synthetic socks
Avoid cotton socks
Workers should change socks midday if boots become wet from snow, sweat, or slush.
Neck gaiters, fleece scarves, or balaclavas protect the face from windburn and frostbite without interfering with safety compliance.
Winter brings PPE challenges that workers do not face in warmer months. High-visibility gear must remain visible even with heavy outerwear.
Class 2 or Class 3 garments are necessary for plowing, flagging, and roadside operations.
Crew jackets should have reflective striping on all sides.
If workers wear non-standard jackets, they must add a high-vis vest over them.
Snow glare and blowing debris require:
Safety glasses
Tinted lenses for bright, sunny days
Anti-fog coatings or wipes for warm breath against cold air
Snowplows, blowers, chainsaws, and loaders are loud even in winter. Use earmuffs or plugs appropriate for weather conditions.
During cold, dry conditions, dust from sanding operations can increase. Workers may need N95s when exposed to dust clouds.
Slip-resistant traction aids provide stability when walking on ice. Workers must remove them before entering vehicles to avoid damaging floorboards and pedals.
Wearing cotton clothing
Wearing too many heavy layers that restrict movement
Leaving wet gloves on for too long
Not adjusting clothing during activity changes
Using non high-vis coats that reduce visibility
Wearing hooded garments that interfere with hearing or side vision
Supervisors play a critical role in winter PPE effectiveness.
They should:
Ensure workers have the proper winter gear before the season begins
Inspect high-visibility apparel to confirm it is still reflective
Encourage regular warm-up breaks
Allow time for workers to change wet clothing
Monitor conditions and adjust assignments when wind chills become hazardous
Make extra clothing, gloves, and warming materials available in shops and vehicles
Proper layering and winter PPE are essential components of cold weather safety for public works and highway crews. When workers stay warm, dry, and visible, they can focus on the job without the added hazards of cold stress, reduced mobility, or visibility issues. Investing in the right gear not only protects workers but improves overall efficiency and safety during winter operations.
