Guidance on Safe Use
Administrative data
First-aid measures
Inhalation
If aerosol or mists are formed:
Move victims into fresh air.
Skin contact
Wash off with plenty of water and soap.
Eye contact
Rinse thoroughly with plenty of water keeping eyelid open.
In case of persistent discomfort: Consult an ophthalmologist.
Ingestion
Have the mouth rinsed with water.
After absorbing large amounts of substance / In case of discomfort: Supply with medical care.
Notes to physician
After absorbing large amounts of substance:
administration of activated charcoal.
Acceleration of gastrointestinal passage
Fire-fighting measures
Suitable extinguishing media
quenching powder, foam, carbon dioxide (CO2), mist
Specific hazards during fire fighting
May be released in case of fire: carbon monoxide, carbon dioxide, sulphur oxides.
Special protective equipment for fire-fighters
In the event of fire, wear self-contained breathing apparatus.
Further information
Water used to extinguish fire should not enter drainage systems, soil or stretches of water.
Ensure there are sufficient retaining facilities for water used to extinguish fire.
Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations.
Accidental release measures
Personal precautions
Wear personal protective equipment.
Environmental precautions
Do not allow entrance in sewage water, soil stretches of water, groundwater, drainage systems.
Methods for cleaning up
Pick up mechanically with a suitable material and collect in a suitable container.
e.g.: adsorption agent, activated charcoal.
Additional advice
Isolate and seal off defective containers immediately.
Handling and storage
Handling
Safe handling advice
Local ventilation.
Always close container tightly after removal of product.
Ensure tightness at all times.
Advice on protection against fire and explosion
Take precautionary measures against static discharges.
Keep away from sources of ignition - No smoking.
Keep away from humidity.
Explosion protection is recommended in case the explosion limits for the following substance might be exceeded: Ethanol.
Storage
Requirements for storage areas and containers
Storage at less than 10 °C may lead to a slight precipitation of crystalline sulfur, which should be removed by mechanical means. The product is not impaired by that.
Keep container tightly sealed and store in a dry, well-ventilated place.
Advice on common storage
Do not store together with: acids and alcaline solutions.
Storage stability
12 month 10 - 40 °C

Additional transport information
Additional information
- Special provisions / remarks / other:
- The substance is not classified as dangerous in the meaning of transport regulations.
Exposure controls / personal protection
Personal protective equipment
Respiratory protection
If respirable aersols / vapour occurs:
Respirator with brown A-type filter
Hand protection
Wear protective gloves made from a tough material.
Glove material butyl-rubber
Material thickness 0,5 mm
Break through time >= 480 min
Glove material nitrile rubber
Material thickness 0,35 mm
Break through time >= 480 min
Glove material Fluorinated rubber (Viton)
Material thickness 0,4 mm
Break through time >= 480 min
The rupture time and material thickness data are guideline values! Exact rupture time / material thickness data can be obtained from the protective glove manufacturer.
Remember that the useful time per day of a chemical protection glove may be much shorter than the permeation time determined according to EN 374 due to the many different influential factors involved (e.g. temperature).
Suitability for specific workplaces should be clarified with protective glove manufacturers.
Eye protection
goggles
Skin and body protection
No special protective equipment required.
When handling larger quantities:
disposable protective suit
(Solvent-resistant)
Hygiene measures
When using, do not eat, drink or smoke. Wash face and/or hands before break and end of work.
To ensure ideal skin protection: use super fatted soaps and skin cream for skin care.
Wash contaminated clothing before re-use.
Protective measures
Handle in accordance with good industrial hygiene and safety practices.
If the limits at the workplace are exceeded and/or larger amounts are released (leakage, spilling, dust) the indicated respiratory protection should be used.
If there is the possibility of skin/eye contact, the indicated hand/eye/body protection should be used.
Stability and reactivity
Materials to avoid
Reaction with water, acids and alcaline solutions., Formation of ethanol and methanol
Disposal considerations
Uncleaned packaging
Contaminated packaging should ideally be emptied; it can then be recycled after having been decontaminated.
Incorrect disposal or reuse of this container is illegal and can be dangerous
Other countries: observe the national regulations.
Waste Key Number
No waste key number as per the European Waste Types List can be assigned to this product, since such classification is based on the (as yet undetermined) use to which the product is put by the consumer.
The waste key number must be determined as per the European Waste Types List (decision on EU Waste Types List 2000/532/EC) in cooperation with the disposal firm / producing firm / official authority.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
