Guidance on Safe Use

First-aid measures

General advice

Consult a physician. Show  this safety data sheet to the doctor in attendance.

Inhalation:

Inhalation is not an expected route of exposure. Remove victim from immediate source of exposure and assure that the victim is breathing. If breathing is difficult, administer oxygen, if available. If victim is not breathing, administer CPR (cardio-pulmonary resuscitation). Seek medical attention.

Skin Contact:

In case of contact, immediately wash with plenty of soap and water for at least 15 minutes. Seek medical attention. Remove contaminated clothing and shoes while washing. Clean contaminated clothing and shoes before re-use or discard if they cannot be thoroughly cleaned.

Eye Contact:

Hold eyelids open and flush with a steady, gentle stream of water for at least 30 minutes. Seek medical Attention, preferably an ophthalmologist. If the physician is not immediately available, eye irrigation should be continued for an additional 15 minutes. If it is necessary to transport the patient to a physician and the eye needs to be bandaged, use a dry sterile cloth pad and cover both eyes.

Ingestion:

If victim is conscious and alert, give 2-3 glasses of water to drink and do not induce vomiting. Seek immediate medical attention. Do not leave victim unattended. To prevent aspiration of swallowed product, lay victim on side with head lower than waist. Vomiting may occur spontaneously. If vomiting occurs and the victim is conscious, give water to further dilute the chemical.

Medical attention and special treatment:

Treat symptomatically.

Fire-fighting measures

Extinguishing media

Suitable Extinguishing Media:

Dry chemical, foam, carbon dioxide, water fog.

Unsuitable Extinguishing Media:

Water. Do not use water jet as an extinguisher, as this will spread the fire.

Special hazards arising from the substance or mixture

During fire, gases hazardous to health may be formed.

Advice for firefighters and special protective equipment:

Promptly isolate the scene by removing all persons from the vicinity of the incident if there is a fire. No action shall be taken involving any personal risk or without suitable training.

Special hazards arising from the substance or mixture:

Carbon oxides, Sulphur oxides

Accidental release measures

Personal precautions:

Keep unnecessary personnel away. Keep people away from and upwind of spill/leak. Keep out of low areas. Wear appropriate protective equipment and clothing during clean-up. Do not breathe mist or vapor. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Ventilate closed spaces before entering them. Local authorities should be advised if significant spillages cannot be contained.

Environmental precautions:

Avoid release to the environment. Contact local authorities in case of spillage to drain/aquatic

environment. Prevent further leakage or spillage if safe to do so. Do not contaminate water. Avoid discharge into drains, water courses or onto the ground.

Methods for containment:

Eliminate all ignition sources (no smoking, flares, sparks, or flames in immediate area). Stop the flow of material, if this is without risk. Dike the spilled material, where this is possible. Collect spillage. Prevent entry into waterways, sewer, basements or confined areas.

Methods for cleaning up:

Ventilate the contaminated area. Extinguish all flames in the vicinity. Wear appropriate protective equipment and clothing during clean-up. Should not be released into the environment. Prevent product from entering drains.

Large Spills: Stop the flow of material, if this is without risk. Dike the spilled material, where this is possible. Cover with plastic sheet to prevent spreading. Do not allow material to contaminate ground water system. Use a non-combustible material like vermiculite, sand or earth to soak up the product and place into a container for later disposal.

Small Spills: Wipe up with absorbent material (e.g. cloth, fleece). Clean surface thoroughly to

remove residual contamination.

Handling and storage

Handling:

Do not breathe dust/fume/gas/mist/vapors/spray. Do not get this material in contact with eyes. Do not get this material in contact with skin.

Do not handle until all safety precautions have been read and understood.

Wear positive pressure self-contained breathing apparatus (SCBA). Wear personal protective equipment.

Wash thoroughly after handling. Avoid release to the environment.

Storage:

Store in a closed container away from incompatible materials. Store in a well-ventilated place.

Keep container dry. Store away from incompatible materials.

Exposure controls / personal protection

Technical protection measures

-Technical conditions and measures:

-Containment: enclosure and automation of mixing process as far as possible and contain area around mixing tank to ensure that exposure level is at acceptable level (PROC4, PROC21, PROC3, PROC2, PROC14, PROC23, PROC24,PROC25, PROC15, PROC8b).

-Local exhaust ventilation (LEV) in mixing step regarding the exposure to carbon disulphide via inhalation route.

-General ventilation: Regarding exposure via inhalation route and hazard from the substance Good general ventilation (3 – 5 air changes per hour) is sufficient to keep the exposure via inhalation at acceptable level. Monitoring of Sulfuric acid emissions from the mixing area and during cleaning and maintenance are recommended when applicable

Organisational measures:

-Environmental, health and safety guidelines or written instructions on the standard operating procedure (SOP) are utilized

-Occupational health and safety management system: basic / advanced

-Environment, health and safety (EHS) responsibilities are defined and assigned in writing

-Emergency action plans (Rescue training for accidental emissions) are created

-Personnel are trained in environment, health and safety issues, i.e. in safe handling of chemicals and good housekeeping

-Good hygiene measures practiced

-It is assumed that a comprehensive PPE program is implemented including selection, fit testing, training in use, maintenance and recording, as appropriate

-Exposure should be controlled primarily by avoidance of contact with the substance, for instance by limiting duration of activity, minimization of manual phases and by minimization of staff exposed

Appropriate engineering controls:

Ensure ventilation is adequate and that air concentrations of decomposition product(s) is/are controlled below quoted Exposure Standards. Avoid generating and breathing in dusts. Use with local exhaust ventilation or while wearing dust mask. Keep containers closed when not in use.

Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.

Personal protective equipment:

Eye/face protection

Safety glasses with side-shields conforming to EN166 Use equipment for eye protection tested

and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).

Skin protection

Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices.

Wash and dry hands.

The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.

Body Protection

Complete suit protecting against chemicals, The type of protective equipment must be selected

according to the concentration and amount of the dangerous substance at the specific workplace.

Respiratory protection

For nuisance exposures use type P95 (US) or type P1 (EU EN 143) particle respirator.For higher

level protection use type OV/AG/P99 (US) or type ABEK-P2 (EU EN 143) respirator cartridges.

Use respirators and components tested and approved under appropriate government standards

such as NIOSH (US) or CEN (EU).

Occupational Exposure Limits:

No value assigned for this specific material by the National Occupational Health and Safety Commission. However, Exposure Standard(s) for decomposition product(s):

Sulfuric acid: 8hr TWA = 0.2 mg/m3,

As published by the National Occupational Health and Safety Commission. TWA - The time-weighted average airborne concentration over an eight-hour working day, for a five-day working week over an entire working life.

These Exposure Standards are guides to be used in the control of occupational health hazards. All atmospheric contamination should be kept to as low a level as is workable. These exposure standards should not be used as fine dividing lines between safe and dangerous concentrations of chemicals.

They are not a measure of relative toxicity.
