Section 4: First - Aid Measures

Description of first aid measures: In case of inhalation: Remove to fresh air. Get medical attention for any breathing difficulty. In case of skin contact: Wash exposed area with soap and water. Get medical advice if irritation develops. In case of eye contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately. In case of ingestion: Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person. Most important symptoms and effects, both acute and delayed: Inhalation: Nuisance dust. May cause coughing, sneezing or laboured breathing if large amounts are inhaled. Ingestion: Considered essentially non-toxic by ingestion. Ingestion of very large amounts may cause sore throat, nausea, headache, and possibly unconsciousness in severe cases. May be converted into hydrogen sulphide in the intestine. May cause irritation. Irritant to human eyes at 6-8 ppm. Redness and pain may be observed. Indication of any immediate medical attention and special treatment needed: Treat symptomatically. Show this safety data sheet to a physician or emergency room.

Section 5: Fire - Fighting Measures

Extinguisher media: Suitable extinguisher media: Use water spray to blanket fire, cool fire exposed containers, and to flush non-ignited spills or vapours away from fire. Solid streams of water should not be used because of possibility of dispersing dust clouds of sulphur in air. Unsuitable extinguishing media: None known.

Safety Data Sheet for Sulphur, Enriched Sulphur According to ISO 11014:2010 First Print Date: 5-Mar-2015 Revision Date: 24-Aug-2019 Version: 1.1.1. Safety Data Sheet (SDS) for Sulphur, Enriched Sulphur https://www.buyisotope.com Page 3/9 Special hazards arising from the mixture: Fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard. Explosive limits, dust in air, gm/cu meter: Lower - 35, Upper - 1400. Hazardous in contact with oxidizing materials; forms explosive mixtures. Advice for fire-fighters: Wear self-contained breathing apparatus for firefighting if necessary. Further information: Standard procedure for chemical fires. Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.

Section 6: Accidental Release Measures

Personal precautions, protective equipment and emergency procedures: Personal precautions: Remove all sources of ignition. Ventilate area of leak or spill. Wear appropriate personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Environmental precautions: Prevent product from entering drains. Prevent further leakage or spillage if safe to do so. Local authorities should be advised if significant spillages cannot be contained. Methods for containment and cleaning up: Methods for cleaning up: 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. Reference to other sections: Treat recovered material as described in the section "Disposal considerations".

Section 7: Handling and Storage

Precautions for safe handling: Advice on safe handling: Avoid dust formation and control ignition sources. Employ grounding, venting and explosion relief provisions in accord with accepted engineering practices in any process capable of generating dust and/or static electricity. Empty only into inert or non-flammable atmosphere. Emptying contents into a non-inert atmosphere where flammable vapours may be present could cause a flash fire or explosion due to electrostatic discharge. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Provide appropriate exhaust ventilation at places where dust is formed. Hygiene measures: Do not eat, drink or smoke when using this product. Conditions for safe storage, including incompatibilities: Requirements for storage areas and containers: Keep in a tightly closed container. Store in a cool, dry, corrosion- proof, ventilated area away from moisture, sources of heat or ignition, combustibles and oxidizers. Protect against physical damage. Avoid dust formation and control ignition sources. Employ grounding, venting and explosion relief provisions in accord with accepted engineering practices in any process capable of generating dust and/or static electricity.

Section 8: Exposure Controls/ Personal Protection

Control parameters: Occupational exposure limits: Contains no substances with occupational exposure limit values.

Safety Data Sheet for Sulphur, Enriched Sulphur According to ISO 11014:2010 First Print Date: 5-Mar-2015 Revision Date: 24-Aug-2019 Version: 1.1.1. Safety Data Sheet (SDS) for Sulphur, Enriched Sulphur https://www.buyisotope.com Page 4/9 Exposure controls: Appropriate engineering controls: Use adequate general or local exhaust ventilation to keep fume or dust levels as low as possible. 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. Individual protection measures, such as personal protective equipment: Eye/face protection: Use safety glasses. If there is a potential for exposure to particles which could cause eye discomfort, wear chemical goggles. Hand protection: Use chemical resistant gloves. Examples of preferred glove barrier materials include: Butyl rubber, Neoprene, Nitrile/butadiene rubber, Polyethylene, Ethyl vinyl alcohol laminate, polyvinyl alcohol, Polyvinyl chloride. Body protection: Wear protective clothing as appropriate. Respiratory protection: None required where adequate ventilation conditions exist. If airborne concentration is high, use an appropriate respirator or dust mask. For conditions of use where exposure to the dust or mist is apparent, a half-face dust/mist respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive pressure, air-supplied respirator.
