3M™ Scott™ ELSA Sprint – Emergency Life Support Apparatus
The 3M™ Scott™ ELSA Sprint 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 3M™ Scott™ ELSA Sprint is available in durations of 10min 2 litre, 15min 3 litre steel cylinders and carbon composite versions 10min and 15min. The sets are carried in high visibility PVC or black anti-static materials. The apparatus consists of a cylinder with combined cylinder valve and reducer, supply hose with tempest demand valve connected to either a positive pressure hood or Promask carried in a storage bag. The 3M™ Scott™ ELSA Sprint is activated upon opening the bag which pulls the cord, which turns the cylinder valve handwheel to open the valve, which can also be manually activated. Medium-pressure air is immediately available at the facemask/hood demand valve which remains closed until the wearer pulls the facemask or hood from, the bag and dons the mask/hood and takes a first, sharp, breath.
Suitable for use in industrial escape settings for escape use only.
The combined cylinder valve and reducer (RCV) reduces the cylinder air pressure and tempest demand valve connects to a
positive pressure facemask (Promask) or hood. The facemask is fitted with a net head harness with 2 straps to tighten when
donning the mask, the hooded variant seals using an elastomeric neck seal.
The carrying bag is made of PVC coated Polyester. This is coloured for high visibility and is both flame retardant 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. Pictogram use instructions and the duration of the air supply are
prominently visible on the bag. The cylinder contents gauge on the cylinder/reducer valve is visible though a transparent panel
in the bag, permitting the cylinder charge state to be checked without opening the bag.
Pneumatics, mask and demand valve
The combined cylinder/reducer valve has a quick-fire cord which can be wound round the cylinder valve handwheel and
attached to the bag’s access flap. The act of opening the access flap pulls the cord, which turns the cylinder valve hand wheel
to open the valve. Medium-pressure air is immediately available at the facemask demand valve, which remains closed until
the wearer pulls the facemask from the bag, dons the mask and takes a first, sharp, breath. This activates the positive pressure
tempest demand valve on the Promask full face mask or hood. The hooded variant has an inbuilt whistle to warn the user to
remove the hood once the air supply is depleted.
Cleaning should only be carried out as specified in the user instructions. Maintenance and servicing must
only be performed by trained personnel following the procedures in the service and maintenance manual.
