1.6 USE IN EXPLOSIVE OR
FLAMMABLE
ATMOSPHERES
Anti-static versions of ELSA apparatus are
approved for use in explosive and
flammable atmospheres. Anti-static
apparatus is provided in a black bag.
Apparatus with a high-visibility orange bag
MUST NOT be used in explosive or
flammable atmospheres.
1.7 TRANSPORTATION
It is essential that ELSA Dash and ELSA
Sprint are transported in suitably
protective packaging.
Refer to the Health and Safety document:
Guide to the Pressure Systems and
Transportable Gas Container Regulations
1989. When breathing apparatus with
charged cylinders is transported by road,
the Road Traffic Regulations 1986 ,
although primarily intended to cover toxic,
flammable and corrosive gases, should be
observed.
After transportation, apparatus must be
checked to ensure that:
•
The bag and contents gauge have
not been damaged.
•
The anti-tamper tag is intact.
2. TECHNICAL
DESCRIPTION
2.1 GENERAL
ELSA Dash and ELSA Sprint are self-
contained, open circuit, compressed air,
short duration, positive-pressure, escape
breathing apparatus that may be stored
ready-for-use within a hazardous area or
carried by the wearer while in a hazardous
area.
Dash is a constant flow apparatus with a
flow rate of 38 litres per minute; that
consists of a compressed air cylinder with
a pressure reducing valve (reducer),
cylinder valve, and hood, contained in a
high-visibility bag, or black anti-static bag.
Sprint is similar to Dash , but has a two-
stage pressure reduction system that
consists of the reducer and a facepiece-
mounted demand valve. The Sprint
facepiece may be a hood or a full
facemask.
Both
Dash and Sprint are available in ten
and fifteen minute versions, with a two litre
or three litre aluminium cylinder.
Pictogram user instructions and the
duration of the air supply are prominently
visible on the bag.
An anti-tamper tag, (that breaks easily
when the bag is opened), provides an
indication that the bag has been opened.
When the apparatus is first delivered, tags
are provided separately, with instructions
for fitting, permitting the contents of the
bag to be checked. Tags must then be
fitted prior to deploying the bag.
The quick-fire cord is attached to the bag
lid and wound around the cylinder valve
handwheel. When the lid is opened the
cord turns the cylinder valve handwheel
and air immediately flows into the hood.
If the valve does not open when the bag is
opened, the cylinder valve handwheel can
be used to open the valve.
The cylinder contents gauge is visible
though a transparent panel in the bag,
thereby permitting the cylinder charge
state to be checked without opening the
bag.
