Determine the hazardous materials present.
Carbon monoxide is present in exhaust from vehicles, gas stoves, fireplaces, and tobacco smoke. It can be dangerous if inhaled in high concentrations, as it can prevent oxygen from being carried in the bloodstream, leading to symptoms such as dizziness, headaches, and in severe cases, death. Proper ventilation and carbon monoxide detectors are important for safety.
The risks of hazardous materials, and the appropriate controls for those risks, depend on the nature of the hazardous material, how much is present, and the environment in which it is present. It is not possible to be more specific with such a general question. Encyclopedias have been written on this subject.

One way of describing a "hazardous materials incident" would be "an accident where hazardous materials are present." However, many people are uncomfortable with the use of the word "accident" which implies an unplanned event that could not have been avoided. That is why the word "incident" is used in the first place. It does not carry any implication of inevitability.
