a speaker associated with the transceiver so that signals broadcast from the transceiver may be audibly perceived;

wherein said transceiver is operable in a first receiving mode when not receiving signals from the transmitter so that said transceiver may receive signals from other transceivers in the WPAN, and in a second transmitting mode when receiving signals from said transmitter so that said signals are broadcast to other transceivers in the WPAN.

2. The short range communications apparatus according to claim 1 wherein the transceiver switches between said first receiving mode when not receiving signals from the transmitter, and said second transmitting mode when receiving signals from the transmitter.

3. The short range communications apparatus according to claim 1 wherein the transceiver includes a manually activated switch for switching between said first receiving mode when not receiving signals from the transmitter, and said second transmitting mode when receiving signals from the transmitter.

4. The short range communications apparatus according to claim 1 including an activation switch on the transmitter, said activation switch including a lanyard attached to the switch.

5. The short range communications apparatus according to claim 4 wherein the lanyard extends beyond the periphery of the face mask.

6. The short range communications apparatus according to claim 1 wherein the transmitter is located entirely within the face mask.

7. The short range communications apparatus according to claim 1 wherein the transmitter is located externally of the face mask.

8. The short range communications apparatus according to claim 1 wherein the transceiver and the speaker are contained in a common housing configured to be worn by a user with the speaker in proximity to the user'"'"'s ear.

9. The short range communications apparatus according to claim 8 wherein the common housing is attached to a boom connected to the face mask.

10. The short range communications apparatus according to claim 1 wherein the speaker is housed separate from the transceiver.

11. The short range communications apparatus according to claim 10 wherein the transceiver is attached to an external surface of said face mask.

12. The short range communications apparatus according to claim 1 further including a sensor configured for collecting data comprising predetermined criteria and for transmitting said data to transceivers in the WPAN.

13. The short range communications apparatus according to claim 12 wherein the transmitter associated with the face mask further defines the transceiver in the WPAN that is capable of receiving signals from the sensor and transmitting the received signals to other transceivers in the WPAN.

14. The short range communications apparatus according to claim 12 wherein the data signals transmitted from said sensor to said transceivers comprise voice signals.

15. The short range communications apparatus according to claim 12 wherein the data signals correspond to and are indicative of the status of equipment worn by a user.

16. The short range communications apparatus according to claim 12 wherein the data signals correspond to and are indicative of a predetermined health status of a user.

17. The short range communications apparatus according to claim 12 wherein the data signals correspond a predetermined environmental condition.

18. A method of facilitating short range communications among members of a working group where each member in the group is wearing emergency equipment including a face mask, comprising the steps of:

(a) providing each member of the group with

i) a wireless transmitter and locating the transmitter in a position relative to the member'"'"'s mouth to enable the transmitter to detect the member'"'"'s voice;

ii) a transceiver capable of receiving signals from the transmitter and transmitting the received signals to other transceivers worn by members; and

iii) a speaker associated with the transceiver so that signals broadcast from the transceiver may be audibly perceived;

(b) transmitting signals from the wireless transmitter to all of the transceivers in the working group; and

(c) switching each member'"'"'s transceiver between a first receiving mode when not receiving signals from that member'"'"'s transmitter so that said transceiver may receive signals from other transceivers in the working group, and a second transmitting mode when receiving signals from that member'"'"'s transmitter so that said signals are broadcast to other transceivers in the working group.

19. The method according to claim 18 wherein the step of transmitting signals includes the step of canceling ambient noise in the environment.

20. The method according to claim 18 including the step of manually switching between said first receiving mode and said second transmitting mode.

21. A communications apparatus for use in a noisy environment, comprising:

a face mask comprising a resilient material configured for providing an effective seal around a wearer'"'"'s mouth and nose to define an interior space between the face mask and the wearer;

a first wireless transmitter module associated with the face mask, said first transmitter module comprising a first microphone located entirely within the interior space;

a second module located externally of said interior space, said second module comprising a second microphone in communication with the first transmitter module, and a second receiver, wherein said second microphone detects ambient noise and generates signals corresponding thereto.

22. The communications apparatus according to claim 21 in which the second receiver is operable to cancel said signals corresponding to ambient noise to thereby reduce ambient noise.

23. The communications apparatus according to claim 21 in which the first wireless transmitter module is operable to cancel said signals corresponding to ambient noise to thereby reduce ambient noise.

24. The communications apparatus according to claim 21 wherein said second module includes a speaker.

25. The communications apparatus according to claim 21 configured for wireless transmission between a second microphone in a first apparatus and a receiver in a second apparatus within a Wireless Personal Area Network.

26. The communications apparatus according to claim 21 wherein said second module is operable in a first receiving mode when not receiving signals from the first microphone so that said second module may receive signals from other transmitters in a working group, and in a second transmitting mode when receiving signals from said first microphone so that said signals are broadcast to other transceivers in the working group.

27. The communications apparatus according to claim 26 wherein the second module switches between said first receiving mode when not receiving signals from the first microphone, and said second transmitting mode when receiving signals from the first microphone.

28. The communications apparatus according to claim 21 including an activation switch on the first microphone, said activation switch including a lanyard attached to the switch that extends out of the interior space.

29. The communications apparatus according to claim 28 wherein removal of the lanyard activates the switch to turn the first wireless transmitter module on.

30. A communications apparatus for use with equipment worn by workers in dangerous environments wherein the equipment includes a face mask, comprising:

a wireless transmitter operatively associated with the face mask;

a transceiver capable of receiving signals from the transmitter and transmitting the received signals to other transceivers;

a speaker associated with the transceiver so that signals broadcast from the transceiver may be audibly perceived; and
