Skin
Redness, swelling and pain may occur.
Eyes
Irritation.

Exposure Controls/Personal Protection

Personal Protection
Wear protective gloves, chemical goggles and protective clothing. If working with product at elevated temepratures - also use repsiratory protection.
Respirators
Use NIOSH/MSHA approved respirator appropriate for exposure.
Poison Class
4

Fire Fighting Measures

Autoignition
230
Fire Fighting
Firefighters should wear full protective clothing and use self contained breathing apparauts. Use water as extinguishing media.

Accidental Release Measures

Small spills/leaks
Clean up personnel should wear full protective clothing - if material exposed to elevated temperatures also wear repsiratory protection. Collect spilled material into suitable labelled containers and hold for later disposal.

Stability and Reactivity
