3rd alarm level for NSI 3000-30 seconds. NSI 3000 Low Carbon monoxide poisoning typically occurs from breathing in carbon monoxide (CO) at excessive levels. Symptoms are often described as "flu-like" and commonly include headache, dizziness, weakness, vomiting, chest pain, and confusion.Large exposures can result in loss of consciousness, arrhythmias, seizures, or death. The classically described "cherry red skin" rarely occurs. This video will inform you of various levels of PPM readings and the relationship to the AQI index.
