ABSTRACT:
Protective mask communication systems are provided for use in hazardous environments, e.g., firefighting and hazardous waste clean-up operations. The systems allow wearers of protective masks working in a hazardous area to readily communicate both with each other and with personnel and automated systems outside of the area. Preferred systems provide short range radio communication between mask wearers.
