|
|
Hazardous Combustion
Products |
Thermal breakdown of this
product during fire or very high heat conditions may evolve the following hazardous
decomposition products: carbon oxides and traces of incompletely burned carbon compounds,
formaldehyde, and silicone dioxide. When heated to temperatures about 150°C in the presence
of air, product can form formaldehyde vapors. Formaldehyde is a potential cancer hazard, a
known skin and respiratory sensitizer, and an irritant to the eyes, nose, throat, skin, and
digestive system.
|
|
Fire-Fighting
Procedures
|
Wear a NIOSH approved
self-contained breathing apparatus. Wear appropriate personal protective equipment. Water
can be used to keep fire-exposed containers cool. Determine the need to evacuate or isolate
the area according to your local emergency plan.
|
|
Containment/Clean-up Techniques
|
Isolate the hazard area.
Keep unnecessary and unprotected personnel from entering the area. Wear all appropriate
personal protection equipment (PPE) (See Section 8). Wipe up or scrape up and contain
for salvage or disposal. Clean the area as appropriate, because the spilled materials
may present a slip hazard. Final cleaning may require use of steam, solvents, or detergents.
Dispose of the saturated absorbent or cleaning materials appropriately, because spontaneous
heating may occur. Federal, state, and local laws and regulations may apply to releases
and disposal of the material, as well as the materials used to cleanup the releases.
|
|
Handling
|
Use with adequate ventilation.
Product evolves acetic acid when exposed to water or humid air. Provide ventilation during
use to control acetic acid within exposure guidelines or use respiratory protection. Avoid
eye contact. Avoid skin contact.
|
|
Storage
|
Use reasonable care and store
away from oxidizing materials. Keep container closed and store away from water or moisture.

Engineering Controls
|
Use local exhaust as needed
to maintain occupational exposure limits. Maintain standard plant ventilation.
|
|
Respiratory
Protection |
Where exposure limits may be
exceeded, select a NIOSH approved respirator with appropriate Protection Factor and cartridge
for the specific contaminants. Follow requirements for respiratory protection in OSHA 1910.134.
|
|
Skin
Protection |
Where skin contact can occur,
wear impervious gloves. Wash at mealtime and end of shift. Contaminated clothing and shoes should
be removed as soon as practical and thoroughly cleaned before reuse.
|
|
Eye
Protection |
Chemical splash goggles
(ANSI Z87.1 or approved equivalent).
|
|
Other
|
Facilities storing or utilizing any
chemical should be equipped with an eyewash facility and a safety shower.
