SECTION 4 FIRST AID MEASURES

EMERGENCY AND FIRST AID PROCEDURES: EYES: Wear eye protection/face protection. If in eyes, rinse cautiously with water for several

minutes. If eye irritation persists, get medical advice/attention.

SKIN: Avoid skin contact. If on skin, wash with plenty of water. Wear protective, chemical resistant gloves (nitrile). Wash thoroughly after handling.

INHALATION: Avoid inhaling dusts, vapors. Remove to fresh air, treat any irritation symptomatically. If breathing is difficult, give oxygen. Get medical attention.

INGESTION: Avoid skin contact. Wash thoroughly after handling. Follow standard hygiene protocols, wash hands before eating, drinking, smoking, applying cosmetics, etc. Never give anything by mouth to an unconscious person. Get medical attention.

EFFECTS OF EXPOSURE: EYES: Can cause eye irritation. Avoid contact with the eyes.

SKIN: Can cause allergic skin reaction. Avoid contact with skin. Wear chemical protective gloves (nitrile)

INGESTION/ INHALATION:

Chronic exposure to RDX dust has been reported to cause convulsions or unconsciousness. Chronic local and systemic effects are not fully known. Inhalation and ingestion can result in systemic poisoning, usually affecting the bone marrow (blood-cell-producing system) and the liver. Avoid inhalation and ingestion of dust or vapors.

SECTION 5 FIRE FIGHTING AND EXPLOSION MEASURES

EXTINGUISHING MEDIA:

Water sprinkler/deluge system recommended. In case of fire, evacuate area. Explosion risk. DO NOT fight fire when fire reaches explosives.

FIRE FIGHTING PROCEDURES: Do not attempt to manually extinguish fires. Burning explosives may accelerate to a detonation at any time when subjected to confinement, shock, or other sufficient initiation source.

FIRE AND EXPLOSION HAZARDS: Must not be confined if burning. Confinement can cause deflagration or transition to detonation with extremely violent results. Explosives may be retained in fissures, cracks, and crevices of structures, equipment and containers which have been exposed to explosives. Property which may be contaminated by explosives must not be subjected to heat, sparks, or flame. Detonation can occur. Thermal decontamination under controlled conditions is the recommended method for complete decontamination. Thermal decontamination must be preceded by washing/steaming and chemical neutralization or dissolution. Contaminated property must not be buried.

HAZARDOUS DECOMPOSITION PRODUCTS:

During decomposition toxic oxides of nitrogen are emitted.

SECTION 6 ACCIDENTAL RELEASE MEASURES

STEPS TO BE TAKEN IN THE EVENT MATERIAL IS RELEASED OR SPILLED: Follow local, state and federal regulations. Clean up spills immediately using a soft bristle brush and a rubber or plastic pan or shovel. Avoid pinching material, metal to metal contact, impact with sharp objects, friction or other situations which may initiate the explosive. Avoid sand, glass, grit, and metal fragments which may sensitize the material to impact and/or friction. Wet with water to desensitize.

WASTE DISPOSAL METHOD: Disposal should comply with all federal, state and local regulations. Waste is considered hazardous waste for reactivity characteristic (D003). Explosives should be destroyed by open burning, by burning in an approved incinerator, or by chemical treatment with caustics. The disposal site should be located to provide adequate quantity-distance protection for adjacent facilities and personnel. Explosives should not be burned in containers. The explosives should be ignited remotely. Personnel should wear flame resistant clothing. The disposal of explosives should comply with all applicable federal, state, and local regulations. Store and handle waste explosives as Class 1 explosives. Transport in accordance with the Department of Transportation regulations.

SECTION 7 HANDLING AND STORAGE

High explosives should be stored in approved explosives magazines. Storage and handling must be carried out in accordance with appropriate Safety Agency regulations concerning quantity distance, barricading, personnel exposure and material handling equipment. Recycle or dispose of used containers in accordance with appropriate Safety Agency regulations. Dust generated by handling must be cleaned up on a continuing basis.

HSAAP Safety Data Sheet Number: 4425 Page 7 of 9

SECTION 11 TOXICOLOGICAL INFORMATION

Acute toxicity:

Toxic if swallowed (oral). Causes mild skin irritation. Can cause allergic skin reaction.

The toxicological properties of RDX have not been fully investigated. TLV- 0.5 mg/m³; RDX LD-LO (lowest lethal dose) Oral – Rabbit – 500 mg/kg; Intraperitoneal – Rat – 10 mg/kg; Oral – Cat – 100 mg/kg; Intravenous – Rat – 18 mg/kg; Oral – Mouse – 500 mg/kg. LD50 Oral - Rat – 100 mg/kg; Oral – Mouse – 500 mg/kg. There is limited information on the toxicity of RDX in humans. Neurological dysfunction, primarily seizures and convulsions, were the most commonly reported effect. The seizures/convulsions typically occurred within several hours of exposure, and in some cases, convulsions were noted for several days after exposure. Other neurological symptoms that have been observed in humans include disorientation, lethargy, muscle twitching and marked hyperirritability. Small decreases in erythrocyte and hemoglobin levels have been found in rodents, but this has not been consistently found in longer-term studies.

Sensitization: RDX is not known to cause sensitization reactions.

Chronic toxicity: No human studies have examined the chronic toxicity of RDX following oral exposure.

Target Organs: Eyes, skin, central nervous system, hematopoetic system. Carcinogenicity: This chemical is not listed as a carcinogen by the International Agency

for Research on Cancer, National Toxicology Program or Occupational Safety and Health Administration.

Further toxicological information: The product should be handled with the care usual when dealing with chemicals.

SECTION 12 ECOLOGICAL INFORMATION

General:

This product should be considered as potentially hazardous to the environment. Avoid contamination of soil, drains and water during handling.

Biologic degradation: RDX undergoes biodegradation in water and soil under anaerobic conditions to form several biodegradation products. Biodegredation producs include MNS, DNX, TNX, hydrazine, 1,1-dimethyl-hydrazine, 1,2-dimethyl-hydrazine, formaldehyde and methanol (ATSDR Toxicological Profile for RDX, 2012).

Behavior in environmental compartments:

RDX is mobile in soil and can leach into groundwater, and can be transported from soils or water to terrestrial and aquatic plants. RDX is not very lipid soluble, and therefore, has a low potential for bioaccumulation in aquatic species.

Ecotoxicity: Limited data available.

Further ecologic data: Do not allow to enter waters, waste water or soil.

HSAAP Safety Data Sheet Number: 4425 Page 8 of 9

Mobility in soil:

RDX can be expected to have a moderate-to-high mobility in soil and leach into groundwater. Adsorption to sediment and particulate matter should not be significant. Greater adsorption appears to occur with an increase in organic matter or clay content (ATSDR, RDX Toxicological Profile).

SECTION 13 DISPOSAL CONSIDERATIONS

Products:

Observe all federal, state, and local environmental regulations. Cleaned up material may also be hazardous waste. Due to reactivity, this product has a RCRA characteristic waste identification of D-003, as designated in 40 CFR 261.23. The waste of this product is subject to the Land Disposal Restrictions and treatment standards for hazardous waste under 40 CFR 268. Transport in accordance with the Department of Transportation regulations. Dispose of in accordance with local, regional, national/international regulations.

Packaging: Disposal in compliance with federal and state regulations. Handle contaminated packaging as contaminated waste, in the same way as the substance itself. If not officially specified differently, non-contaminated packaging may be treated like solid waste or recycled. Dispose of in accordance with local, regional, national/international regulations.
