An SCBA frame for mounting self-contained breathing apparatus bottle vertically such that the frame can articulate with the back of a user, comprising an upper plate, intermediate plate and a lower plate each connected by attachment mechanisms. Each of the plates may comprise a top edge, a bottom edge, and a pair of sides. A first coupling mechanism coupled to the bottom edge of the upper plate and a top edge of the intermediate plate and a second coupling mechanism coupled to the bottom edge of the intermediate plate and the top edge of the lower plate. The first and second coupling mechanisms allow the upper plate, intermediate plate, and lower plate to move about the horizontal axis and torsionally in line with the user's movement. The first and second coupling mechanism comprises a pair of attachment mechanisms located proximate the sides of the upper plate and intermediate plate.

A gas tank storage bag, including a cylindrical main body to store at least one item therein, a back support pad disposed on at least a portion of the cylindrical main body to prevent at least a portion of the cylindrical main body from collapsing in response to movement thereto, a shoulder strap assembly disposed on at least a portion of a top portion of the cylindrical main body to suspend the cylindrical main body from shoulders of a user, and a waist strap assembly disposed on at least a portion of a bottom portion of the cylindrical main body to connect around a waist of the user.

A protective shield is provided for covering a self-contained breathing apparatus (SCBA) mask or a full-face air purifying respirator (APR) lens to prevent damage and scratching. The shield consists of a die cut shape of thermoplastic sheet that duplicates the outline of the self-contained breathing apparatus mask lens and/or frame. The protective shield can be produced using various grades, colors and/or densities of material replicating limited visibility or blackout conditions. To protect the majority of the plastic lens, the shape of the shield includes a peripheral overlap onto the mask utilizing the SCBA lens frame. The shield can be attached to the self-contained breathing apparatus face mask by means of any of the following: bungee, hook, or elastic cord; all of which allows the shield to be attached or removed quickly. Many SCBA/APR training exercises require limited visibility. The invention can be used as an effective training tool to prevent light transmission and simulate extremely limited visibility.

There is disclosed a harness for breathing apparatus comprising a structural support member for supporting a vessel of breathable gas, a waist belt, and a pivot joint mechanism coupling the structural support member to the waist belt. The pivot joint mechanism comprises a release part which is movable to decouple the structural support member from the waist belt.

The oxygen delivery device is a portable structure. The oxygen delivery device contains a plurality of oxygen canisters. The plurality of oxygen canisters contain oxygen under pressure. The oxygen delivery device stores the plurality of oxygen canisters. The oxygen delivery device dispenses the oxygen contained in the plurality of oxygen canisters. The oxygen delivery device comprises a housing, a distribution apparatus and the plurality of oxygen canisters. The housing contains the plurality of oxygen canisters and the distribution apparatus. The housing: a) stores the plurality of oxygen canisters; and, b) forms a fluidic connection between the plurality of oxygen canisters and the distribution apparatus. The distribution apparatus delivers the oxygen received from the plurality of oxygen canisters for consumption.

A mask stowage container is provided having a door panel coupled to a box via a securement mechanism, the securement mechanism having a striker having a neck and a protrusion, the striker mounted to the door panel, a holder, the holder including a first retainer and a second retainer, the striker configured to be laterally retained between the first retainer and the second retainer.
