We reviewed all 87 deaths from the Happy Land Social Club fire. All deaths were due to smoke inhalation. The carboxyhemoglobin (COHb) concentrations ranged from 37 to 93% with a mean of 76.5%. ⋯ Carboxyhemoglobin concentrations corresponded well with deaths from smoke inhalation. Cyanide concentrations did not correspond with the extent of smoke inhalation, and the role of cyanide in contributing to these deaths is doubtful. Hydrogen chloride inhalation, as evidenced by comparison of the pH of tracheal mucosa to controls, was not a factor.
