Safety & protection
Exposure Control and Personal Protection
TIH (Toxic Inhalation Hazard) - Term used to describe gases and volatile liquids that are toxic when inhaled. Some are TIH materials themselves, e.g., chlorine, and some release TIH gases when spilled in water, e.g., chlorosilanes. [ERG 2016].
Toxicology
Adverse EffectsDermatotoxin - Skin burns.
