First-aid measures

General information:
There are adequate first aid/medical facilities, trained personnel and equipment, including first aid response capabilities. The emergency eyewash and shower are inspected regularly. The provisions and procedures are under the company’s management system and also under authorities' surveillance.
The precautions in case of accident are:
Inhalation of gases:
- Provide fresh air, warmth and rest, preferably in comfortable upright sitting position. Get medical attention if any discomfort continues.
Skin contact:
- Remove immediately contaminated clothing and shoes. Rinse immediately with plenty of water. Contact physician.
Eye contact:
- Rinse immediately with plenty of water. Hold eyelids apart. Contact physician.
Ingestion:
- Rinse mouth with water. Drink a few glasses of water. Do not induce vomiting. Contact physician.

Fire-fighting measures

The material is combustible. Combustion gases may contain toxic sodium oxide (Na2O) vapours.
There are provisions and procedures in place for fire emergency situations under the company’s management system. There are appropriate fire fighting equipment including manual extinguishing equipment under management and authority surveillance and inspections (water, foam, dry chemicals or carbon dioxide). There are emergency evacuation procedures, training and fire drills are undertaken regularly. The full procedures and responsible persons are described in the emergency preparedness plan. The fire extinguishers are inspected regularly. There is cooperation and surveillance of the plant operations by the local fire department / corresponding authorities. Self contained breathing apparatus and a protection suit are required for fire fighting.


Accidental release measures

There are provisions and procedures in place for emergency situations that base on a risk assessment conducted to assess all known and potential hazards and under the Company’s management system.
During accidental situations procedures are in place to contain the intermediate within the process buildings / site. In case of accidental spillage, larger amounts should be absorbed and properly disposed of. Smaller spills may be diluted with water.
There are procedures in place also to inform people living in the surroundings and authorities of process disturbances and other special situations such as temporary process shut downs.
Environmental precautions:
- Small amounts can be rinsed with plenty of water. If a large amount has been released, start pumping waste water into the guard basin.
Methods for cleaning up:
- Rinse thoroughly with plenty of water.
Other precautions:
- Avoid reactions with acids. The substance liberates very toxic and flammable hydrogen sulphide (H2S) gas in contact with acids. pH lowering may cause release of acetic acid.

Handling and storage

The processes are closed. The intermediate is manufactured and consumed (turned into another substance) during its whole life cycle under strictly controlled conditions.
For loading and unloading, maintenance and emergency situations where limited exposure could potentially exist there are specific guidance and procedures, c.f. exposure controls / personal protection, Safety Data Sheets available for staff etc.
The staff is trained to a level pertinent to their post in all relevant operations of the plant and equipment at the site under the company’s management system.
There are specific provisions and procedures in place for certain tasks: hot work, working in ATEX premises, maintenance of pressurized equipment, working inside tanks, tunnels and pits, working in high places etc.
There are safety signs and labelling on chemical tanks and in certain areas.
The handling and storage of chemicals is under surveillance of authorities.

Additional transport information

Additional information
Special provisions / remarks / other:
Do not allow contacts with acids. pH lowering may cause release of acetic acid and hydrogen sulphide (H2S), which is a toxic and flammable gas.

Exposure controls / personal protection

The processes are closed. The intermediate is manufactured and consumed (turned into another substance) during its whole life cycle under strictly controlled conditions.
Exposure control elements in place include:
- Continuous monitoring of operations and processes, as well as environment automatically and by chemical and physical analysis and site inspections and walk through in operational premises.
- Emergency preparedness procedures, e.g. emergency preparedness plan under the company’s management system.
- Employee training procedures under the company’s management system.
- Employee health checks and other health care services.
- Surveillance of the company’s operations by authorities.
- Security and control, e.g. of access into the site.
Risk management measures implemented to minimise any exposure include:
- In case of handling substance Personal Protective Equipment (PPE) such as chemical resistant protective gloves and clothing and eye/face protection needs to be used and if necessary appropriate mask respirator with air.
- As the substance is corrosive, process equipment are checked regularly.
- Additionally good ventilation of working spaces is provided.
- Stationary hydrogen sulphide (H2S) measuring devices are installed in areas of H2S hazard.
- Measurement for hydrogen sulphide (H2S) is performed before work is conducted with equipments (tanks, etc.).
- Personal hydrogen sulphide (H2S) measuring devices is carried during work inside process equipment (e.g. during maintenance).

Stability and reactivity

The substance is stable at normal circumstances.
Contact with acids liberates toxic and flammable gas (hydrogen sulfide). pH lowering may cause release of acetic acid.

Disposal considerations

Under normal operation, no amount of the substance is generated that would require disposal considerations. If disposal is required, the substance is handled as dangerous waste.
