Conventional fire alarms work effectively to warn people of the danger by sounding an alarm. But that means nothing to hearing-impaired people as they could hear nothing. So what could wake up hearing-impaired people in time? The unusual fire alarm designed by Kobe-based fire extinguisher company- Air Water Safety Service and the Tokyo-based Bioventure Seems looks like a practical solution. It is based on hearing impaired people’s keen sense of smell and warns them by releasing wasabi stench. The new fire alarm also works effectively, for example, one 8 in x 3 in unit could alarm people within an area of up to 50 square feet in less than three minutes. The smelly fire alarm is bit of expensive at present, each costing about $560. But a reasonable price of $225 will be possible after further improvements.
