PRODUCT NAME: Estes Model Rocket Engines PRODUCT NUMBER: SECTION 4 - FIRST AID MEASURES INHALATION: If symptoms of lung irritation occur (coughing, wheezing or breathing difficulty), remove from exposure area to fresh air immediately. Get medical attention in the unusual event of severe distress. EYES: Remove contact lenses, then wash for 15 minutes with clean potable water lifting upper and lower lids occasionally. Seek medical attention if irritation persists. SKIN: Wash with plenty of soap and water. Seek medical attention if delayed dermatitis develops (a rare condition). INGESTION: Contact medical authorities immediately. Do not induce vomiting unless directed to do so by medical personnel. If vomiting occurs naturally, have victim lean forward to avoid aspiration of regurgitant. Give 1-2 glasses of water to victim if victim is conscious and able to swallow and seek immediate medical assistance. Never give anything by mouth to an unconscious person. Note to Physician: This product contains nitrates, which may produce methemoglobinemia. Methylene blue may be required for treatment. Treatment should be aimed at reducing methemoglobin levels, as well as providing respiratory and metabolic support. As product contains charcoal, gastric lavage may be of benefit within 30-60 minutes post-ingestion. SECTION 5 - FIRE FIGHTING MEASURES GENERAL HAZARDS: Flammability Classification: (defined by 29 CFR 1910.1200) Class 1.4 Explosive.

Product will not mass explode if multiple devices are involved. Burning material may produce toxic and irritating vapors. See Emergency Response Guidebook for further information. Mechanical impacts or electrical discharges are highly unlikely to cause product to ignite. EXTINGUISHING MEDIA: Where large quantities are affected, flood area with water; if fire is already consuming product, incident command should base fire- fighting decisions on capabilities and total quantity of product. If no water is available, carbon dioxide, dry chemical or earth may be used. FIRE FIGHTING PROCEDURES: In case of fire, use normal fire fighting equipment. Protection concerns must also address the potential of the physical characteristic of this product as explosive. Quarantine area for fires involving large quantities of product. UNUSUAL FIRE AND EXPLOSION HAZARDS: If fire reaches a large quantity of product, consider a withdrawal of personnel to a safe distance. Evacuate all persons, including emergency responders from the area for at least 500 feet (1/10 mile) in all directions. HAZARDOUS COMBUSTION PRODUCTS: Carbon Monoxide, Carbon Dioxide, Nitrous Oxides, Sulfur Oxides SECTION 6 - ACCIDENTAL RELEASE MEASURES STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Model rocket engines are devices in a solid state.

Respiratory Protection: Respiratory protection is required whenever air contamination (dust, mist, or vapors) is generated by the process. A NIOSH approved high efficiency toxic dust/mist/fume respirator is recommended. Work Practices and Engineering Controls: General room ventilation is adequate unless the process generates dust or fumes. Work-clothing should be removed in a change room on site and laundered professionally. Employees should shower and change into street clothes before leaving the facility. Prevent the accumulation of dust in the work area by thorough periodic cleaning of the area. Protective Measures During Repair and Maintenance: No special measures are required.
