  1. How are the ensembles packed prior to shipping?

    The ensembles are put together with the chemical suit inside the overcover. The two suits are then snapped at the face shield before being folded and put into bag.   Go to top



  2. Do the NFPA® overcovers come with boots attached?

    No, they have sock boots attached to suits and should be worn with an NFPA® certified over boot. Compliance with NFPA® 1991, 2000 Edition requires Beta Haz-Max #87012 boots be worn over the integrated booties.   Go to top



  3. Is it possible to wear a regular Responder® suit with a certified overcover and be NFPA® certified?

    No, it is not possible to buy a regular Responder® suit together with a certified overcover; however, DuPont sells separate overcovers that are not certified for people that want to use an overcover in a non-certified ensemble.   Go to top



  4. Are the same part numbers used for the overcovers that are not NFPA® certified?

    No, the part numbers for the fiberglass non-certified overcovers are: Tychem Responder® AL620S front entry, AL621S rear entry.  Go to top



  5. Does the aluminized overcover offer chemical protection?

    No, the aluminized overcover does not offer chemical protection, but the Responder® suit that are worn under it does offer a broad range of chemical protection. The aluminized overcovers also offer very good flash fire protection.   Go to top



  6. What is a flash fire?

    A chemical flash fire is the combustion or burning of flammable vapors or gases; typically occurring in enclosed or confined spaces. A flash fire is the ignition of a gas in the air generating radiant heat energy. Flash fires generate extreme temperatures (649-816º C, 1200-1500º F) for a short period of time (5-10 seconds).   Go to top



  7. May the overcovers be repaired?

    Yes, unless the damage is too severe. Tears may be sewn up with fire resistant thread made from Nomex®-brand or Kevlar® fibers. However, there is no method to repair abrasion of the aluminized coating.  Go to top



  8. May the overcovers be reused?

    Overcovers should not be reused if physical damage or chemical degradation is visible.  Go to top



  9. May the overcovers be decontaminated?

    As with any personal protective equipment, decontamination depends on the degree of chemical exposure, amount of contamination, and the type of chemical present. In some situations it may be possible to decontaminate a garment, and in other situations, disposal is the best form of decontamination.   Go to top



  10. Does DuPont offer a durable storage bag for the NFPA® Ensembles?

    Yes, a storage bag made of DuPont? StaSafe® Hi-Glo, which is a high visible lime green PVC fabric, is available to accommodate all NFPA® Ensembles. This bag is available as a made-to-order item and may be purchased from an authorized StaSafe® distributor. Contact Standard Safety customer service at 815-363-8565 for additional details.   Go to top
