Tingley J44241.LG Arc Flash Jacket Large Nomex 14 Cal

Product Description

The TINGLEY J44241.LG is a Nomex arc flash protective jacket sized for a 44 to 46 inch chest (Large). Built for electrical workers and industrial technicians who require arc-rated PPE, this jacket carries an arc rating of 14 cal/cm2, meeting the threshold for NFPA 70E Hazard Risk Category compliance. The shell is constructed from 10.50 oz Nomex fabric at 0.38 mm thickness, offering flame resistance without relying on chemical treatments that can wear off with laundering. Closure is via snaps, and wrist fit is secured with hook-and-loop adjusters. Seams are Therm-O-Rad sealed to maintain arc protection integrity at stress points.

This jacket is intended for electricians, utility workers, and industrial maintenance personnel working in environments where arc flash hazards are present. It is appropriate for use in both commercial and industrial settings where NFPA 70E or OSHA 1910.269 arc-rated PPE requirements apply. The Large size accommodates chest measurements from 44 to 46 inches, making it suitable for a wide range of working builds. It is designed to be worn as part of a layered arc flash PPE ensemble or as a standalone outer layer depending on the incident energy exposure level of the task.

Installation Notes

This garment is donned and removed by qualified electrical workers as part of a PPE risk assessment procedure conducted prior to energized work. Always verify that the full PPE ensemble meets or exceeds the calculated incident energy level of the task per NFPA 70E arc flash analysis. Inspect the jacket before each use for damage to seams, fabric, or closures that could compromise arc protection. Launder per the manufacturer care instructions to preserve Nomex flame resistance properties.
