SENSITIVITY TO STATIC DISCHARGE
Sensitivity to static discharge is not expected.
EXTINGUISHING MEDIA
All standard extinguishing agents are suitable.
SPECIAL FIRE FIGHTING PROCEDURES
Firefighters must wear NIOSH/MSHA approved positive pressure self-contained breathing
apparatus with full face mask and full protective clothing.
6. ACCIDENTAL RELEASE MEASURES
ACTION TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED
Wipe, scrape or soak up in an inert material and put in a container for disposal. Wear proper protective
equipment as specified in the protective equipment section. Increase area ventilation.
7. HANDLING AND STORAGE
STORAGE
Keep container closed. Store away from heat, sources of ignition, and incompatibles.
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE
Avoid contact with skin and eyes. Use only in well-ventilated areas. Keep away from children. May
generate formaldehyde at temperatures greater than 150 C (300 F). See Section 10 of MSDS for
details.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
ENGINEERING CONTROLS
Eyewash stations; Showers; Ventilation and other forms of engineering controls are preferred for
controlling exposures. Respiratory protection may be needed for non-routine or emergency situations.
RESPIRATORY PROTECTION
If exposure limits are exceeded or respiratory irritation is experienced, NIOSH/MSHA approved
respiratory protection should be worn. Supplied air respirators may be required for non-routine or
emergency situations. Respiratory protection must be provided in accordance with OSHA regulations
(see 29 CFR 1910.134).
PROTECTIVE GLOVES
Impermeable or chemical resistant gloves.
EYE AND FACE PROTECTION
Safety glasses with side-shields conforming to EN 166
