Introduction
Cold climates shift the PPE equation: you must combine thermal insulation with FR and arc protection. A winter FR garment must protect against arc flash and thermal exposure while preventing cold stress.
Key winter hazards to consider
- Cold stress and hypothermia
- Wet conditions and insulation loss
- Need for mobility when wearing multiple layers
Design & material solutions
- Insulated FR linings(inherent FR fleece, quilted aramid insulation)
- Soft-shell & hard-shell combos with water-repellent FR outer layers
- Modular 2-pc systems for layering and ventilation control
- Seam sealing & reflective trims for wet, dark conditions
Harbor365 winter lines
- Sentinel Winter Parka: AR-coated, thermal quilt, ATPV-rated panels.
- Quill Insulated Coverall: full-body insulation with articulated joints.
- Everyday Thermal Jacket: lightweight FR fleece for mild winters.
Layering strategies
- Base layer: moisture wicking (non-melting fibers)
- Mid layer: insulating inherent FR fleece
- Outer shell: windproof, water resistant, arc-rated outer fabric
Maintenance & storage during winter
- Dry garments completely before storage; keep spares available; keep track of ATPV after repairs.
Harbor365 use-case
Deployed in northern oilfields and cold-climate renewable sites with feedback of improved comfort and lower shivering-related incidents.
FAQs
Q: Can insulation reduce ATPV?
A: Layering is complex—only tested systems guarantee ATPV; Harbor365 tests common layering combinations and provides certified guidance.
