EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

Effects of short-term exposure
If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. 

Inhalation risk

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. 


Occupational exposure limits
 

ENVIRONMENT
The substance is very toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment. 

NOTES
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
