Principal routes of exposure are usually by skin contact/eye contact and inhalation of vapor/spray mist. Prolonged skin contact may cause skin reactions and susceptibility to skin infections. As with any chemical product, contact with unprotected bare skin; inhalation of vapor, mist or dust in work place atmosphere; or ingestion in any form, should be avoided by observing good occupational work practice.
