If you really wanted to there are indoor air filter machines that you can buy to help clean the air, (I have one of these) also frequently dusting you house with an approved cleaner can stop allergy's as moving around can cause dust to go flying around. Now if this is a humidity problem you can buy a humidifier, now the hot air humidifiers are not good so your best bet would be to get a cool air humidifier witch uses high speed movement to create humidity. (I also have one of these)
Concscious victims you can talk to and locate the pain and figure how to treat. Unconscious victims you have to believe the worse and wait and see after the test results come back.
