3M RM407 facepiece with fireproof head cover for premium protection.

RM407 Facepiece with Flame-Resistant Hood: Full Protection for Powered Systems

The 3M RM407 facepiece is a premium solution for workers exposed to respiratory and mechanical hazards. It includes a hard hat, impact-resistant visor, flame-resistant sealing bib, and flame-resistant hood, offering complete protection for the face, head, and neck. This model is especially recommended in industrial settings where hard hats are mandatory and where risks of splashes or heat are present.

The RM407 facepiece consists of a hard hat, visor, flame-resistant sealing bib, and flame-resistant hood, making it the top choice for intensive factory work, especially where head protection and high contaminant concentrations are required. The hard hat features a six-point suspension and ratchet adjustment mechanism. Additionally, the RM407 is certified Type 1, Class G and meets the ANSI Z89.1-2003 standard for industrial head protection. The RM407 hard hat is made of a PC and PBT blend—polycarbonate and polybutylene terephthalate—making it flame-resistant. Note that it is not yet CSA-approved. This product offers a protection factor of 1000 times the permissible exposure limit.

The RM407 meets ANSI Z87.1-2010 standards regarding eye and face protection. 3M RM407 is equipped with a premium visor and a flame resistant faceseal. RM927 visor is made of an anti-scratch covered polycarbonate resistant to impacts. A RM928 peel-off visor cover comes with the complete system.

The RM407 facepiece features an air deflector that allows airflow direction adjustment—either toward the face or the visor. It also includes the flame-resistant RM444 bib made of polyamide knit coated with polyurethane. To achieve the protection factor of 1000, a Nomex IIIA RM447 hood covers the facepiece down to the shoulders. The outer hood is flame-resistant thanks to the Nomex IIIA material. This equipment is ideal for bearded users, as its size makes it virtually impossible to interfere with the sealing membrane.
