Notes on other potential health effects and hazards:

  1. Petroleum distillates are combustible (NIOSH/IPCS 2001).
  2. This mixture may contain n-hexane, which is metabolized to the neurotoxin 2,5-hexanedione (see hexane) (Creaser et al. 1983; Ono et al. 1982).
  3. Exposure to petroleum distillates may increase the risk of developing undifferentiated connective tissue disease (UCTD) (Lacey et al. 1999).
