Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
Ingestion: Never give anything by mouth to an unconscious person. Get medical attention.
Skin Contact: Wipe off excess material from skin then immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse.
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.
Note to Physician: Symptomatic and supportive treatment is recommended.

Flammability of the Product: May pose a fire hazard when exposed to elevated temperatures or by contact with an ignition source.
Auto-Ignition Temperature: NA.
Flash Points: NA.
Flammable Limits: NA.
Products of Combustion: It emits toxic oxides of carbon and oxides of sulfur when heated to decomposition.
Fire: Sodium thiosulfate pentahydrate may ignite at high temperatures.
Explosion: An explosion may occur if triturated with nitrates, chlorates, or permanganates. Fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition source may pose dust explosion hazard.
Fire Extinguishing Mediaa: Water spray. Use means suitable for extinguishing surrounding fire. Water spray, dry chemical, alcohol foam, or carbon dioxide.
Special Information In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures or when moistened under fire conditions, it may produce toxic or irritating fumes.

Small Spill: Avoid dust formation. Avoid breathing dust. Ensure adequate ventilation. Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements.
Large Spill: Do not let the product enter drains. Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow evacuating through the sanitary system.

Do not breathe dust. Wear suitable protective clothing. In case of insufficient ventilation, wear suitable respiratory equipment.
Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Wash hands thoroughly after handling. Provide appropriate exhaust ventilation at places where dust is formed. If you feel unwell, seek medical attention.
Keep Sodium thiosulfate pentahydrate in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage or contact with oxidizing material and combustible substances.

Airborne Exposure Limits: None established.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Dust deposits on floors and other surfaces may pick up moisture and cause the surfaces to become slippery and present safety hazards. Handle in accordance with good industrial hygiene and safety practice. Wash hands after handling.
