The dose and frequency strongly depend on the formulation and intended use of the matrix to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.

4.17.2.   Use-specific risk mitigation measures

If discharged into seawater 0,2 mg/L glutaraldehyde must not be exceeded in the hydrotesting and mothballing fluids. This concentration can be achieved either by slow release and/or long retention times resulting in degradation of glutaraldehyde and/or by dilution and/or by addition of sodium bisulphite at pH 5 (release after at least 20 minutes) or addition of sodium hydroxide to pH 12 (release after at least 10-16 hours) as degradation aids. Hydrotest and mothballing water containing up to 750 mg/L glutaraldehyde after the pressure test can be used for re-injection. Run lab test to determine the soiling dependent dosage and degradation rate in use.

When applied onshore, preserved fluids must be recycled or disposed of as hazardous waste. If release to the sewer is unavoidable, the concentration shall not exceed 1 mg glutaraldehyde/L.

4.18.1.   Use-specific instructions for use

Glutaraldehyde is typically applied through a closed system to a mixing tank using a pump Glutaraldehyde may be used in combination with other chemistries such as friction reducers, gelling agents, proppants, and corrosion inhibitors, and applied together with these chemistries in the mixing tank(s). If used for intermittent treatments during operations, a stream of glutaraldehyde will be directly dosed into the process water stream from a separate tank into a closed system, thereby significantly reducing the chance of exposure.

Dose 50 to 1 000 g glutaraldehyde per m3 fracturing fluid, in the hydraulic fracturing water matrix.

The dose strongly depends on the formulation and intended use of the matrix to which the preservative is added. Therefore, the user shall determine dosage requirements for their specific matrix/system to be preserved. The lowest effective dose shall be used. If needed, consult the authorisation holder of the preservative product.

4.18.2.   Use-specific risk mitigation measures

Preserved fracturing fluids are reused where applicable. If discharged into seawater 0,2 mg glutaraldehyde/L fracturing fluid must not be exceeded. This concentration can be achieved either by slow release and/or long retention times resulting in degradation of glutaraldehyde and/or by dilution and/or by addition of sodium bisulphite at pH 5 (release after at least 20 minutes) or addition of sodium hydroxide to pH 12 (release after at least 10-16 hours) as degradation aids. Run lab test to determine the soiling dependent dosage and degradation rate in use.

When applied onshore, preserved fluids must be recycled or disposed of as hazardous waste. If release to the sewer is unavoidable, the concentration shall not exceed 1 mg glutaraldehyde/L.

4.18.3.   Where specific to the use, the particulars of likely direct or indirect effects, first aid instructions and emergency measures to protect the environment

See general directions for use. In addition:

Conditions preventing emissions to water:

Emissions to surface water are prevented through the design of the installation. By way of example spills, leaks and cleaning solutions may be drained to a lined storage area, preventing release to surface water. Sub-surface releases of fluid during the fracturing process are prevented from reaching aquifers through the presence of relatively

impermeable formations above the target formation. This limits upward migration of fluid. This is also relevant for recovered fluids that are re-injected for use or disposal. A minimum vertical separation distance between the target formation and aquifer should be respected. National legislation may also require a minimum depth

Recovered water may finally be discharged via one or more large-scale waste water treatment plants where a combination of physical and biological treatments will reduce emissions to the receiving water.

Conditions preventing emissions to soil:

Emissions, through downward migration are prevented through the design of the installation. By way of example spills, leaks and cleaning solutions may be prevented from downward migration to soil by the employment of a non-permeable membrane below the well pad. Sludge from treatment works should not be spread on land.

Existence of standard municipal sewage treatment plant

Waste contractors employed to dispose of recovered water, may do so via a waste water treatment plant, depending on the properties of the water and conditions of local regulations.

4.18.4.   Where specific to the use, the instructions for safe disposal of the product and its packaging

See general directions for use. Additional:

Contaminated water arising from cleaning will be collected and removed for disposal according to EU and local regulations and conditions.

Waste product remaining in containers after use will be returned, in the containers, to the supplier for cleaning/refilling.

Waste sludge from treatment works will be handled as industrial waste and not spread on land.

5.3.   Particulars of likely direct or indirect effects, first aid instructions and emergency measures to protect the environment

IF INHALED: Move to fresh air and keep at rest in a position comfortable for breathing.

If symptoms: Immediately call 112/ambulance for medical assistance.

IF SWALLOWED: If conscious, immediately rinse mouth. Give something to drink, if exposed person is able to swallow. Do NOT induce vomiting. Call 112/ambulance for medical assistance.

IF ON SKIN: Immediately wash skin with plenty of water. Thereafter take off all contaminated clothing and wash it before reuse. Continue to wash the skin with water for 15 minutes. Call a POISON CENTRE or a doctor. If skin irritation or rash occur: Get medical advice.

IF IN EYES: Immediately rinse with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing for at least 15 minutes. Call 112/ambulance for medical assistance.

Information to Healthcare personnel/doctor:

Immediately initiate life support measures, thereafter call a POISON CENTRE.

Environmental precautions: Prevent from entering into soil, ditches, sewers, waterways and/or groundwater. Spills or discharge to natural waterways is likely to kill aquatic organisms.

Personal precautions, protective equipment and emergency procedures in case of accidental release measures: Evacuate area. Keep upwind of spill. Ventilate area of leak or spill. Only trained and properly protected personnel must be involved in clean-up operations. Use appropriate safety equipment.

Methods and materials for containment and cleaning up: Avoid making contact with spilled material, since glutaraldehyde will be absorbed by most shoes. When cleaning up a spill always wear the appropriate protective equipment, including respiratory protection, gloves, protective clothing and eye protection. A self-contained breathing apparatus or respirator and absorbents may be necessary, depending on the size of the spill and the adequacy of ventilation.

Small spills: Wear the correct protective equipment including gloves and protective clothing and cover the liquid with absorbent material. Collect and seal the material and the dirt that has absorbed the spilled material in polyethylene bags and place in a drum for transit to an approved disposal site. Rinse away the remaining spilled material with water to reduce odour, and discharge the rinsate into a municipal or industrial sewer, not into a natural waterway.

Large spills: In case of nasal and respiratory irritation, vacate the room immediately. Personnel cleaning up should be trained and equipped with a self-contained breathing apparatus, or an officially approved or certified full-face respirator equipped with an organic vapor cartridge, glove, and clothing impervious to glutaraldehyde, including rubber boots or shoe protection. Deactivate with sodium bisulfite (2-3 parts (by weight) per part of glutaraldehyde), collect the neutralized liquid and place in a drum for transit to an approved disposal site.

5.4.   Instructions for safe disposal of the product and its packaging

The biocidal product, when being disposed of in its unused and uncontaminated state should be treated as a hazardous waste according to EC Directive 2008/98/EC.

Deactivate with sodium bisulfite (2-3 parts (by weight) per part of glutaraldehyde), collect the neutralized liquid and place in a drum for transit to an approved disposal site. If the concentration of glutaraldehyde is up to 2%, deactivate by the addition of aqueous sodium hydroxide solution in an amount sufficient to maintain a pH of 12 for 8 h, followed by neutralization (i.e. neutral pH) with the careful addition of an inorganic acid e.g. hydrochloric acid, before disposal by appropriate means. Any disposal practices must be in compliance with all national and provincial laws and any municipal or local by-laws governing hazardous waste. Do not dump into any sewers, on the ground, or into any body of water. Avoid release to the environment. High-temperature incineration is an acceptable practice glutaraldehyde burns cleanly to carbon dioxide and water.

Containers used to store glutaraldehyde solutions are non refillable. Do not reuse or refill the containers. Containers should be triple or pressure rinsed with water promptly after they are emptied. They can then be offered for recycling or reconditioning for biocidal products, or they can be punctured and disposed of in a sanitary landfill or by other procedures approved by national and local authorities. Send waste liquid from rinsing of used containers to an approved waste handling facility.

5.5.   Conditions of storage and shelf-life of the product under normal conditions of storage

Do not store in and avoid contact with aluminum, carbon steel, copper, mild steel, iron. Avoid contact with amines, ammonia, strong acids, strong bases, strong oxidizers.

Store at temperatures <40 °C
