Understanding the Safety Standards
The Portwest FR428 technical datasheet (PDF) lists NFPA 2112, ASTM F1506 and the ASTM F1959 arc test result. NFPA 2112 addresses flame-resistant clothing for short-duration thermal exposure from fire; ASTM F1506 addresses flame-resistant, arc-rated protective clothing. Portwest also lists NFPA 70E, a workplace electrical-safety standard used for PPE selection, not a standalone garment certification.
OSHA Requirements and Garment Selection
OSHA 29 CFR 1910.335(a)(1)(i) requires electrical protective equipment appropriate to the work and exposed body parts. For covered electric-power work, 1910.269(l)(8) sets additional requirements for arc and flame hazards.
CAT 2 does not authorize every energized task. Select the complete clothing and PPE system through the applicable hazard assessment. These jeans do not provide electrical insulation against shock, and their arc rating is not a guarantee against injury.
Fit, Care and Replacement
Check the Size Chart tab and garment measurements before ordering. Confirm freedom of movement and coverage with your work boots and upper-body FR clothing. Follow the sewn care label: Portwest lists washing up to 40°C, no bleach and low-temperature tumble drying. Inspect for tears, damaged seams and contamination before use; remove unserviceable garments from the protective-clothing program.
FAQ
- Are these jeans fireproof? No. Flame resistance reduces specific thermal risks but does not eliminate burn hazards.
- What does ATPV 14 cal/cm² mean? It is the reported arc thermal performance value under the applicable laboratory test, not a safe exposure duration.
- Can I wear them with ordinary workwear? Follow the employer’s clothing requirements. Other layers and exposed areas must be appropriate for the assessed hazard.
- Will they fit over work boots? The wide hems are designed for boots; check your intended combination for fit and coverage.
- Which sizes can I order? ASA lists women’s sizes 2, 4, 6, 8, 10, 12 and 14. Select from the current product options.
- Are these sold by the case? The listed selling unit is one pair of jeans.
