It is my understanding that anyone can get RADS if they are exposed to a concentrated and massive exposure to irritant gas, vapor, fume, smoke, dust or chemicals.This could be from a chemical spill, leak, fire or explosion. RADS usually develops quickly and often symptoms stay for a long period of time. There is no latency period and it is not an allergic reaction and you are not born with RADS.
The diagnostic criteria for RADS:-
1. Absence of pre-existing respiratory disorder, asthma symptomatology or a history of asthma in remission and
exclusion of conditions that can simulate asthma
2. Onset of asthma after a single exposure or accident.
3. Exposure is to an irritant vapor, gas, fumes or smoke in very high concentrations.
4. Onset of asthma occurs within minutes to hours and always less than 24 hours after the exposure.
5. Finding of a positive methacholine challenge test (<8 mg/ml) following the exposure.
6. Possible airflow obstruction on pulmonary function testing.
7. Another pulmonary disorder to explain the symptoms and findings is excluded

Reactive Airways Dysfunction Syndrome or RADS is a term proposed by Stuart M. Brooks M.D. and colleagues in 1985 [3] to describe an asthma-like syndrome developing after a single exposure to high levels of an irritating vapor, fume, or smoke.[4] It involves coughing, wheezing, and dyspnea.[5]
It can also manifest in adults with exposure to high levels of chlorine, ammonia, acetic acid or sulphur dioxide, creating symptoms like asthma.[6] The severity of these symptoms can be mild to fatal, and can even create long-term airway damage depending on the amount of exposure and the concentration of chlorine. Some experts classify RADS as occupational asthma. Those with exposure to highly irritating substances should receive treatment to mitigate harmful effects.[7]

Some occupations that are more prone to exposures may include:-
FIRE FIGHTERS
WELDERS BAKERS |
MANUFACTURING WORKERS
PAINTERS HOSPITAL STAFF |
CONSTRUCTION WORKERS
MINERS POLICE OFFICERS |
FARMERS
CLEANERS SES & PARAMEDICS |
Also ... I have had emails from people with RADS who were exposed in their homes to high levels of fumes etc. ... so it can happen at home and at work. Please ensure you have good ventilation after getting mold removed or after using strong cleaning chemicals.
