-> Wear personal protective gear.
-> Ensure that there is good ventilation.
-> If you do come into contact, wash off immediately with plenty of warm water and contact a doctor if necessary.

NOTICE

Pentosin

- Water hoses can soften and may be damaged irreparably

-> Always keep water hoses away from Pentosin.
-> Water hoses that come into contact with Pentosin must be thoroughly cleaned immediately.
-> Water hoses that have already been contaminated with Pentosin over a long time must be replaced.

Information

- Close off PDCC lines using suitable stoppers if the reservoir is not installed immediately.
