The products all contained myclobutanil, a fungicide that can transform into hydrogen cyanide when burned.
"You certainly don’t want to be smoking cyanide," said Antonio Frazier, the vice president of operations at CannaSafe. "I don’t think anyone would buy a cart that was labeled hydrogen cyanide on it."
Looking as the MSDS for myclobutanil[1]:
- the fire hazard for health is rated as 1 (low), suggesting burning the product isn't a major health concern
- oral acute toxicity starts at 1.5g/kg or over 100 gram for an average adult
- inhalation toxicity is 2.1 mg/L while the products generally showed single digit part per million levels
No, it's not good when there are pesticides in your vape, but these tests don't suggest they are the cause of the vape illnesses.
Accute toxicity will be a few % of that. Assuming the conversion efficency is reasonable, chronically inhaling a few ppm of HCN would be bad. Possibly as bad as chronically inhailing high concentrations of aerosolized thermally degraded oils.
Firefighting risk is a general environmental risk - fighting a fire puts you in an area with fire byproducts. (not to mention the PPE firefighters usually wear) Vaping cuts out the environment part & introduces the combustion byproducts directly to your lungs.
