The Scott Safety ELSA Muster is a positive pressure escape set providing air on demand for situations where the escape route may require a lot of physical exertion or where the maximum levels of protection are required. The ELSA Muster has an ancillary air in attachment for use at Muster stations. The ELSA Muster is an open circuit, positive pressure airline breathing apparatus consisting of anti-static bag, high pressure reducing valve, automatic positive pressure demand valve and coupling for airline supply hose. The ELSA Muster is supplied with either a Positive Pressure Face Mask or with a Positive Pressure hood.
The constant flow hood is manufactured from polyurethane coated viscose with clear PU visor. This provides a stretch material for a comfortable fit combined with an elastomeric neck seal giving ease of donning over spectacles, beards and long hair. The optionally clear bubble visor is made from polyurethane. The mask has an exhale valve for increased performance and a compact ¼ mask reduced rebreathed CO2 levels. Compact positive pressure demand valve featuring servo-assisted, tilting diaphragm mechanism with low inspiratory resistance and responsive dynamic performance, automatic first breath activation and hands free bypass facility. Components injection moulded from Polyamide with rubber seals and diaphragms.
First stage pressure reducing valve featuring non-adjustable, spring loaded piston mechanism and outlet supply protected by pressure relief valve. Valve body and cap machined from nickel-plated brass with stainless steel spring and hose retainer U-clips. The carrying bag is made of PVC coated nylon. This is coloured for high visibility and is both flame retardant and chemical splash resistant. There is an anti-static option for working in potentially explosive atmospheres and this is made of polyurethane. The bag can be worn across the chest, as a bandolier or worn with an optional waist belt.
