Tetrakis Hydroxymethyl Phosphonium Sulfate THPS

In the USA, UAE, Iran Iraq, Kuwait, Saudi Arabia and other oil producing areas, several hundred chemical compounds are used in hydraulic fracturing also called fracking, fracing or frac. In some areas like UK only 'Non-Hazardous' chemicals are permitted for fracturing fluids by the Environment Agency. All chemicals have to be declared publicly and increasingly, food additive based chemicals are available to allow fracking to take place safely.

Mubychem is an internationally preferred source for Stimulation Chemicals and Hydraulic Fracturing Chemicals. We serve various oil and shale gas producing countries like USA UAE, Kuwait, Iran, Iraq, Saudi Arabia, UK, Europe India etc. We are never too far from your well-site with multiple 24/7 company owned or rented warehouses in the India, USA and across the globe. With customers in several countries, we sell almost all the fracturing chemicals.

EINECS EC Number: 259-709-0
Percentage: 70-80% (Typically 75% in water).

4. First Aid Measures

Inhalation: Remove affected person to fresh air; if normal breathing has not returned within a few minutes after exposure, get medical attention.
Skin
: Remove contaminated clothing; wash affected area with soap and water; launder contaminated clothing before reuse. Seek medical attention.
Eyes
: Immediately, flush eyes for 15 minutes in clear running water while holding eyelids open; seek medical attention immediately.
Ingestion: Drink two glasses of water followed by milk, milk of magnesia or other non-alcoholic liquids; Do not induce vomiting; seek medical attention immediately.
Physician may treat symptomatically.

5. Fire Fighting Measures

Flash Point:  96° C (204° F)
Flammable Limits:
LEL: Not Applicable
UEL:     Not Applicable
NFPA CLASS: IIIB
General Hazards: Contact with eyes causes immediate severe irritation of the eye and eyelids. Product will support combustion.
Extinguishing Media: Carbon dioxide, water fog, dry chemical, chemical foam.
This product would not be expected to burn unless all the water is boiled away. The remaining organics may be ignitable. Keep containers cool by spraying with water. Use extinguishing media appropriate for surrounding fire.
Fire & Explosion Hazard: May evolve oxides of carbon (COx) under fire conditions. May evolve oxides of phosphorus (POx) under fire conditions. May evolve oxides of sulfur (SOx) under fire conditions.
In case of fire, wear a full face positive-pressure self contained breathing apparatus and protective suit. Self - contained respiratory equipment; cool containers to prevent pressure buildup and possible explosion when exposed to extreme heat. Caution - material will support combustion!
Unusual Fire and Explosion Hazards: Closed containers of THPS can explode due to buildup of pressure when exposed to extreme heat.
Hazardous Combustion Products: Products of combustion include smoke, toxic fumes, oxides of carbon to include carbon monoxide, phosphorous oxides, phosphine and sulfur oxides.
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 under fire conditions, it may produce toxic or irritating fumes. Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place.

6. Accidental Release Measures

Personal precautions, protective equipment, and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind. Do not touch the spilled material.
Environmental precautions: Do not let the product enter drains, soil, or water sources.
Methods and materials used for containment Cleanup procedures and Storage: Do not inhale dust, vapors, mist, or gas. Avoid dust formation. Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite). Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate as per law. THPS will support combustion. Avoid contact with eyes.

7. Handling and Storage

Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. Wash thoroughly after handling. Do not drink, eat, or smoke while handling. Avoid contact with skin, eyes, and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Prevent any contact with hot surfaces.
Conditions for safe storage, including any incompatibilities: Store in cool, dry, and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like strong oxidizing agents and strong bases. This material will support combustion. Keep this and other chemicals out of reach of children.

8. Exposure Controls/Personal Protection

Engineering Controls: The use of local exhaust ventilation is recommended to control emissions near the source. Provide mechanical ventilation of confined spaces. Use corrosion-resistant, explosion-proof ventilation equipment.
Exposure Limits: ACGIH-TLV 2mg/m3 TWA; OSHA-PEL 2mg/m3
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.
