SECTION 7: HANDLING AND STORAGE

difficulty persists.

Skin Contact: Rinse immediately with plenty of water. Obtain medical attention if irritation develops or persists.
Eye Contact: Rinse cautiously with water for at least 15 minutes. Remove contact lenses, if present and easy to do. Continue

rinsing. Obtain medical attention.

Ingestion: Do NOT induce vomiting. Rinse mouth. Immediately call a POISON CENTER or doctor/physician.
Most Important Symptoms and Effects Both Acute and Delayed
General: Vapors are heavier than air and may cause asphyxia by reduction of the oxygen content.
Inhalation: May cause respiratory irritation.
Skin Contact: May cause skin irritation. Liquid contact may cause frostbite.
Eye Contact: May cause eye irritation.
Ingestion: Ingestion is likely to be harmful or have adverse effects.
Chronic Symptoms: None expected under normal conditions of use.

Indication of Any Immediate Medical Attention and Special Treatment Needed
If you feel unwell, seek medical advice (show the label where possible).

Extinguishing Media
Suitable Extinguishing Media: Use extinguishing media appropriate for surrounding fire.
Unsuitable Extinguishing Media: None known.
Special Hazards Arising From the Substance or Mixture
Fire Hazard: RS - 44 is not flammable at atmospheric pressure and in air at temperatures up to 100 °C (212 °F). RS - 44 should

not exist with air/excess oxygen at elevated pressures and high temperatures. RS - 44 Can become combustible with high
concentrations of air at elevated pressure and/or temperature and in the presence of an ignition source. These substance can
also become combustible in an oxygen enriched environment (oxygen concentrations greater than that in air). For example, do
not mix RS - 44 with air under pressure for leak detection purposes.
Explosion Hazard: Product is not explosive. Heat may build pressure, rupturing closed containers, spreading fire and increasing
risk of burns and injuries.

Reactivity: Hazardous reactions will not occur under normal conditions.
Advice for Firefighters
Precautionary Measures Fire: Exercise caution when fighting any chemical fire.
Firefighting Instructions: Use water spray or fog for cooling exposed containers.
Protection During Firefighting: Do not enter fire area without proper protective equipment, including respiratory protection.
Hazardous Combustion Products: Carbon oxides (CO, CO2). Halogenated hydrocarbons. Hydrogen Fluoride (HF).
Reference to Other Sections

Refer to section 9 for flammability properties.

Personal Precautions. Protective Equipment and Emergency Procedures
General Measures: Avoid all contact with skin, eyes, or clothing. Avoid breathing vapors.
For Non-Emergency Personnel
Protective Equipment: Use appropriate personal protection equipment (PPE).
Emergency Procedures: Evacuate unnecessary personnel.
For Emergency Personnel
Protective Equipment: Equip cleanup crew with proper protection.
Emergency Procedures: Stop leak if safe to do so. Ventilate area.
Environmental Precautions

Avoid release to the environment.

Methods and Material for Containment and Cleaning Up
For Containment: Ventilate area.
Methods for Cleaning Up: Isolate area until gas has dispersed.
Reference to Other Sections

See Heading 8. Exposure controls and personal protection.

Precautions for Safe Handling
Additional Hazards When Processed: Ruptured cylinders may rocket.
Hygiene Measures: Handle in accordance with good industrial hygiene and safety procedures. Wash hands and other exposed

areas with mild soap and water before eating, drinking or smoking and when leaving work.

Conditions for Safe Storage, Including Any Incompatibilities
Technical Measures: Comply with applicable regulations.
Storage Conditions: Store in a dry, cool and well-ventilated place. Keep container closed when not in use. Keep/Store away

from direct sunlight, extremely high or low temperatures and incompatible materials.

Incompatible Materials: Strong acids. Strong bases. Strong oxidizers. Chlorine.
Storage Area: Store in a well-ventilated place.
