Potential Health Effects
----------------------------------
Inhalation:
No adverse health effects via inhalation. Formation of large quantities of extremely toxic gases, notably oxides of nitrogen, hydrogen cyanide and carbon monoxide may occur upon decomposition. Effects from exposures to decomposition products are severe and life threatening.
Ingestion:
Although ingestion is highly unlikely, swallowing may result in mild stomach upset.
Skin Contact:
Not expected to be a health hazard from skin exposure. May cause mild irritation and redness.
Eye Contact:
Although eye contact is highly unlikely, it may result in severe pain.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
No information found.
Inhalation:
Not expected to require first aid measures. Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion:
Not expected to require first aid measures. If large amounts were swallowed, give water to drink and get medical advice.
Skin Contact:
Not expected to require first aid measures. Wash exposed area with soap and water. Get medical advice if irritation develops.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids occasionally. Get medical attention if irritation persists.
Fire:
Flash point: 13C (55F)
Autoignition temperature: 165C (329F)
Presents an unusually severe fire hazard; when dry, ignites readily and burns explosively. Should never be kept for any appreciable time in any dry fibrous state. Unstabilized product decomposes gradually at relatively low temperature, with evolution of copious volumes of toxic and flammable gases, and rapid heat generation. The resulting flameless decomposition is self-sustaining and accelerative, presenting the added hazard of dangerous pressures in building structures. This material contains sufficient oxygen to self-sustain burning even in oxygen-deficient atmospheres.
Explosion:
For unstabilized, dry material: An explosion may be initiated by sudden shock, by high temperature or by a combination of the two. Sensitive to mechanical impact. Sensitive to static discharge.
Fire Extinguishing Media:
Water spray, dry chemical, alcohol foam, or carbon dioxide.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode. Use extreme caution in approaching fires. It may explode. Do not fight advanced fires, except for remote activation of installed fire extinguishing equipment and/or with unmanned fixed turrets and hose nozzles. The surrounding area should be evacuated. Fires should be approached from upwind. Use self-contained breathing apparatus. Since cellulose nitrate supplies its own oxygen, prompt cooling with a large quantity of water is essential; water applied through spray nozzles is effective if used quickly and in sufficient volume.
Dangerous material. Partially decomposed material may detonate or autoignite. Handle decomposed material as an explosive that may detonate with mild shock using explosive disposal procedures.
Remove all sources of ignition. Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Clean up spills in a manner that does not disperse dust into the air. Use non-sparking tools and equipment. Reduce airborne dust and prevent scattering by moistening with water. Pick up spill for recovery or disposal and place in a closed container.
Containers should be protected against damage and not exposed to heating. Storage area should be segregated, well ventilated, and equipped with both decomposition and explosion vents, having the maximum amount of free opening. Protect against excessive heat and direct sunlight, avoid contact with electric light bulbs, steam coils, or other sources of heat; prohibit open flames or other sources of ignition. Control ignition sources. Employ grounding, bonding, venting and explosion relief provisions in accord with accepted engineering practices in any process capable of generating an explosion due to static discharge. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
Airborne Exposure Limits:
None established.
Ventilation System:
In general, dilution ventilation is a satisfactory health hazard control for this substance. However, if conditions of use create discomfort to the worker, a local exhaust system should be considered. Use explosion-proof equipment.
Personal Respirators (NIOSH Approved):
Not expected to require personal respirator usage.
Skin Protection:
Wear protective gloves and clean body-covering clothing.
Eye Protection:
Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.

Stability:
Stable at room temperature in sealed containers. For unstabilized, dry material: An explosion may be initiated by sudden shock, by high temperature or by a combination of the two. Heat and sunlight can contribute to instability.
Hazardous Decomposition Products:
Emits toxic fumes of hydrogen cyanide, nitric oxides, and carbon monoxide when heated to decomposition. Incomplete combustion may generate toxic hydrogen cyanide fumes.
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Strong oxidizers.
