/ Reliable / Hands-Free
CON-SPACE communication equipment was designed with considerable input from
aircraft maintenance personnel to provide a reliable, continuous and safe
method of communication between safety attendant(s) and Fuel Cell Technicians.
Users can con-verse freely, like a conference call. Conver-sation is totally
hands-free and without delay. Users have NO buttons to push or bulky belt
packs to wear. The clarity of communications, allows the safety attendant
to immediately detect a problem with the entrant such as erratic breathing
or slurring of speech, etc. and significantly reduces any stress, confusion
or panic that can result from working in an aircraft fuel cell.
In addition to the inherent safety provided by the equipment it also addresses
many practical concerns. In maintenance work where time is of the essence,
no longer does the entrant have to crawl back through a cell, scream through
a face mask, or learn elaborate tapping codes to communicate with personnel
outside the space. CON-SPACE equipment does not emit potentially dangerous
EIRP (Effective Isotropic Radiated Power) like radio equipment and is not
subject to minimum separation distances from open fuel cells. Unlike radio
dead spots, delays or interference from barriers or heavily shielded areas
are not a problem when using CON-SPACE equip-ment. The intercom is a completely
private network allowing workers to concentrate on there task without outside
interference or monitoring. It also provides valuable link through which
maintenance person-nel can discuss alternatives without leaving the space.
Users of CON-SPACE equipment are finding numerous areas in which the equipment
can be utilized to save time. For example, Boeing estimates a 20% increase
in productivity and a signifi-cant improvement in quality by utilizing CON-SPACE
equipment to provide real time communication between Buckers and Riveters
manufacturing wing sections. Other maintenance activities include; 747 Pylon
Modifica-tion, DC-10 Tail Stab repair, Sheet metal installation and repair
and a variety of Inspection and Training activities.
Numerous accessories have been developed to allow the users to easily integrate
the equipment into their daily routines. When working in high noise or a
hazardous environment requiring breathing apparatus, CON-SPACE has developed
a series of Face Mask Communication Sets. A Face Mask Communication Set
consists primarily of an newly designed Throat Mic for voice and a variety
of Speaker styles to hear. These accessories can be used in conjunction
with any type or style of full face breathing apparatus. The triple shielded
and Skydrol resistant cable can be joined together with a supplied air line
to create an easily managed single entrant umbilical.
Another commonly used accessory is the CSI-2130 Talk Box, a CON-SPACE exclusive.
The Talk Box is a two-way proximity communication device. When lowered into
or taken into a fuel cell the Talk Box can provide full two-way communication
within a 6 foot radius without the entrant having to wear any accessory.
It is designed to work in moderate to low noise environ-ments when the entrant
does not have to wear breathing apparatus.
All CON-SPACE Confined Space communication systems have an emergency alarm
capability. This provides Confined Space entrant(s) with the ability to
initiate a continuous audible alarm outside the space in the event that
the safety attendant removes his communication headset or is absent from
the hole's entrance. The alarm, in conjunction, with continuous communication
provides an added measure of safety, security and peace of mind to anyone
working in Confined Spaces.
Anywhere / Anytime
All system modules are completely water and dust tight. Furthermore, a complete
system for fuel cell use fits neatly into a rugged carrying case and is
powered by standard alkaline batteries, so it can be quickly and easily
deployed anywhere aircraft maintenance must be done.

Communication Ties It All Together
Communication equipment for Fuel Cell Maintenance is as important as
Personal Protective Equipment, Breathing Apparatus, Gas Detectors, Photo
Ionization Detectors, and Ventilation equipment and is the one piece of
equipment that ties the whole operation together and allows personnel to
work together as a cohesive unit. Following are some examples of how communication
equipment can be applied, to maximize the safe use of other equipment common
to fuel cell entry.
Communication & Gas Detection
Monitoring for explosive or poisonous environments is common practice in
fuel cell maintenance. The space is continuously monitored prior to and
during entry. Atmospheric monitoring equipment generally stays with the
safety attendant on the outside of a space. When an alarm sounds the possibility
exists that entrant might not hear it. When entrants are working in high
noise, at a distance or out of sight, the attendant must have a means to
tell the entrant of the alarm and to evacuate the space immediately.
On the other hand, small, portable gas moni-tors can be carried by entrants
and sample gases in which they are actually working. This type of gas monitoring
complements monitoring at the point of entry. For this type of program to
work properly and keep permit documentation current the attendant should
have a means of receiving periodic readings from the entrant's monitor and
note them on the permit. If an entrant monitor sounds an alarm and the distance
is significant and/or ambient noise levels are high, entrant(s) must have
a means of immediately notifying the safety attendant of the change in atmosphere
and coordinating corrective ventilation and/or the egress from the tank.
Communication & Breathing Apparatus
Fuel Cell entry requiring the entrant to use Breathing Apparatus is greatly
enhanced by an easy method of continuous communica-tion. Apparatus common
for Fuel Cell entry is a Supplied Air Respirator (SAR). This equipment has
the advantage of being able to provide workers with a virtually unlimited
supply of air. In addition to the physical size and weight advantages (i.e.
No large air tank to carry).
CON-SPACE communication equipment provides a valuable link if there is
a problem with breathing apparatus and/or an alarm sounds. Any one who has
ever experienced a loss of breathing air can tell you the immediate reaction
is one of panic and confusion. Being able to immediately call for help or
just having a voice in your ear can do a lot to calm these fears and reduce
the possibility of mistakes made during a period of confusion or panic.
During entries where more than one tech-ni-cian is "on air"
it can be difficult to communicate with others working in the same space
due to the face mask obstructing conversation. CON-SPACE equipment provides
fully open communication and is compatible with any type of face mask.
Communication & Ventilation
Ventilation equipment is used widely in Fuel Cell maintenance. If a problem
with the air flow occurs or airborne hazards (i.e. carbon monoxide from
vehicle exhaust or fumes from chemicals), are accidentally introduced into
a space, the communication system allows the attendant to inform the entrant(s)
of a potential problem. In addition the attendant can continuously monitor
the entrant(s) for any behavioral or adverse affects caused by a change
in atmosphere within the Fuel Cell. Also the entrant(s) have the ability
to immediately notify the attendant of any strange smells or changes that
may not be evident to the attendant located outside the space.
Time is critical in any rescue operation but in a Confined Space Rescue
it is even more precious. Continuous communication between a fuel cell worker
and a safety attendant can save valuable time in the recognition of a problem
and subsequent notification of a rescue team. Any reduc-tion in the amount
of time it takes to recognize a problem and shorten the rescue team's response
to the scene could mean the difference between "retrieving" or
"recovering" a worker from a Fuel Cell.
