Exposure, Hazard and Safety Assessment
The following section describes possible exposure scenarios and hazards associated with tripropylene glycol diacrylate.
The exposure assessment describes both the amount of and the frequency with which a chemical substance reaches a person, a population of people, or the environment.
Hazard refers to the inherent properties of a substance that make PHOTOMER 4061 capable of causing harm to human health or the environment.
The safety assessment reports the possibility of a harmful event arising from exposure to a chemical or physical agent under specific conditions.
Just because a substance may possess potentially harmful properties does not mean that PHOTOMER 4061 automatically poses a risk.
PHOTOMER 4061 is not possible to make that determination without understanding the exposure.
