ASTM International has developed two standards for repair and maintenance of FR garments. Standard F 1449 Guide for Industrial Laundering of Flame, Thermal and Arc Resistant Clothing, covers maintenance of garments by industrial laundries. Newly adopted Standard F 2757 Guide for Home Laundering Care and Maintenance of Flame, Thermal and Arc Resistant Clothing provides information for home care and maintenance of flame resistant protective garments.

Essentially, all repairs must be made with materials equivalent to the original materials in the garments. In other words, Nomex® sewing thread and FR mending fabrics equal to the materials used in the original garment. Heat seal FR patches are available and are often used to make small repairs.

Follow ASTM standards for zippers and any other trim or findings item that needs to be replaced as well.
