4. FIRST AID MEASURES
EYES: Immediately flush with large amounts of water for at least 15 minutes, occasionally lifting the upper and lower
eyelids. If eye irritation develops, call a physician.
SKIN : Immediately wash with soap water for at least 15 minutes. Call a physician if needed. If clothing comes in
contact with the product, the clothing should be removed immediately and should be laundered before re-use.
INGESTION: Immediately drink large quantities of water. Induce vomiting. Call a physician at once. When vomiting
occurs, keep head lower than hips to help prevent aspiration. DO NOT give anything by mouth if the person is unconscious or if having convulsions. INHALATION:
 If person experiences nausea, headache or dizziness, person should stop work immediately and move to fresh air until these symptoms disappear. If breathing is difficult, administer oxygen, keep person warm and at rest. Call physician.  In event that an individual inhales enough vapor to lose consciousness, person should be moved to fresh air at once and a physician should be called immediately. If breathing has stopped, artificial respiration should be given immediately.  In all cases, ensure adequate ventilation and provide respiratory protection before the person returns to work. 5. FIRE FIGHTING MEASURES
DANGER!!
Extremely Flammable – Explosives
Accidental Explosion May Cause Severe Injury or Death
Evacuate the area immediately in case of emergency.

FLASH POINT:
FLAMMABLE LIMITS: Not Determined
AUTOIGNITION TEMPERATURE: 160°C – 180°C (320° F - 360°F)
No explosion – 5 hours at 120°C (248°F) EXTINGUISHING MEDIA:
Apply large volumes of water as quickly as possible from automatic sprinklers or with fire hose from a distant, protected location. FIGHT EXPLOSIVE FIRES ONLY FROM WELL PROTECTED, DISTANT (FROM POINT OF FIRE) LOCATION. Since product is self-oxidizing, smothering agents such as dry chemical, carbon dioxide, or foam are ineffective. PERSONAL PROTECTION FOR FIREFIGHTING

Self contained breathing apparatus (SCBA) and protective clothing, to include impervious boots, gloves, hard hat, and chemically impermeable suit. Eye and face protection. Wash all clothing prior to reuse. UNUSUAL FIRE AND EXPLOSION HAZARDS:
Product is self oxidizing. Products are propellant explosives and are extremely flammable and readily ignited. Protect from fire, sparks, impact and high temperatures. DO NOT move or approach containers which have been damaged due to exposure to heat. Keep unnecessary people away, isolate hazard area. Use only trained and qualified clean up personnel wearing appropriate protective clothing to clean up heat damaged product. HAZARDOUS DECOMPOSITION PRODUCTS: None expected, if stored and handled as in Section 7.
HAZARDOUS PRODUCTS OF COMBUSTION. Combustion products vary depending on fire conditions and other
combustibles present in the fire. The predominant products will be carbon dioxide, and nitrogen oxides. Under some conditions, methane, carbon monoxide, irritating aldehydes and carboxylic acids, and MATERIAL SAFETY DATA SHEET MSDS No. –WPI – A21

6. ACCIDENTAL RELEASE MEASURES
SPILL PROCEDURES:
Clean up spills immediately using soft bristle brush and conductive rubber or plastic shovel. Use caution, material is sensitive to initiation from sources such as heat, flame, impact, friction or sparks. AIR RELEASE:
WATER RELEASE:
 This material is heavier than water. Create an overflow dam with filtration capabilities to retain material.  Divert water flow or stop if possible. Gather wet material using non-sparking or plastic utensils.  Keep material damp until ready for disposal. LAND SPILL:
 Clean up of spill materials may be accomplished using non-sparking or plastic utensils. Wear non- flammable or flame retardant clothing at all times. Wet all spill materials prior to initiating clean up procedure.  Material may best be destroyed by controlled open burning in small quantities (maximum about 1 pound) in piles not over 1 inch deep. Use an ignition train of slow-burning, combustible materials to permit retreat to a safe distance before powder is ignited. Stay upwind, do not breathe products of combustion. Burn only with permission of all appropriate regulatory agencies. WASTE DISPOSAL:
 If this product becomes a waste, it meets the criteria of a hazardous waste as defined under 40 CFR 261 and would have the following EPA hazardous waste number: D003  If this product becomes a waste, it will be a hazardous waste which is subject to the Land Disposal Restrictions under 40 CFR 268 and must be managed accordingly.  If this material becomes a waste, it can be disposed by controlled open burning in small quantities, as described above, with proper local agency authorization.
CARE MUST BE TAKEN TO PREVENT ENVIRONMENTAL CONTAMINATION FROM THE USE OF THIS
MATERIAL. THE USER HAS THE RESPONSIBILITY TO DISPOSE OF UNUSED MATERIAL, RESIDUES
AND CONTAINERS IN COMPLIANCE WITH ALL RELEVANT LOCAL, STATE AND FEDERAL LAWS AND
REGULATIONS REGARDING TREATMENT, STORAGE AND DISPOSAL FOR HAZARDOUS AND
NONHAZARDOUS WASTES.
7. HANDLING AND STORAGE
HANDLING AND STORAGE PRECAUTIONS:
For handling and storage requirements see 29 CFR 1920.109. Also see <<Properties and Storage of Smokeless Powder>> published by the SPORTING ARMS AND AMMUNITION MANUFACTURES’ INSTITUTE; INC. (SAAMI), PO Box 838, Brandford, CT 06405. This product may react with acids, oxidizing agents, alkalizes or amines (organic and inorganic) and should not be stored near such materials.  Avoid exposure to sunlight or artificial ultraviolet light.  Recommended storage conditions -: 21°C (70°F) 50% relative humidity.  Keep away from heat, sparks and open flame.  Store in a cool, dry place.  Do not store smokeless powder in the same area with solvents, flammable gases or highly combustible  Must be stored in original DOT approved containers or shipping container.  Do not smoke in areas where powder is stored or used.

Section 7 - Continued

 Do not keep old or salvaged powders. Check old powders for deterioration regularly. Destroy  Empty containers may contain residues of powder, and should be treated as hazardous waste. ENGINEERING CONTROLS:
Adequate ventilation should be provided to keep dust concentrations below acceptable exposure limits. Discharge from the ventilation system should comply with applicable air pollution control regulations. PROTECTIVE MEASURES DURING REPAIR AND MAINTENACE:
Eliminate ignition sources and prevent build-up of static electric charges. Thoroughly clean up all powder grains and dust residues in the maintenance and repair aieas before starting work. 8. EXPOSURE CONTROL / PERSONAL PROTECTION

ESTABLISHED EXPOSUR LIMITS

COMPONENT
OSHA (PEL)
ACGIH (TLV)

PERSONAL PROTECTIVE EQUIPMENT
 Safety glasses or goggles with side shields.  Impervious gloves.  Appropriate respiratory protection required when exposure to airborne containment is likely to exceed acceptable limits. Respirators should be selected and used in accordance with OSHA Subpart I (29 CFR 1910.134) and manufacturer’s recommendations.  Flame-retardant cotton coveralls and conductive safety shoes.
ENGINEERING CONTROLS
Adequate ventilation should be provided to keep dust concentrations below acceptable exposure limits. Discharge from the ventilation system should comply with applicable air pollution control regulations. Use a local mechanical ventilation system if needed, preferably with explosion proof construction, and with a suitable dust filter installed at inlet to suction piping to the system to prevent accumulation of explosive dust in ventilation piping and blower.
