Vacuum distillate (shale oil), middle

Guidance on Safe Use

First-aid measures

Contact with the substance is unlikely under normal circumstances. Strict containment of the intermediate is mandatory at all times. In the event of accidental release, skin and eye contact may be relevant routes of exposure when handling the substance. Ingestion is taken into account (see below), but is unlikely under normal handling. Inhalation can be ruled out in principle. However, in the event of unintentional release in enclosed spaces, appropriate precautions should be taken due to the possible concentration of volatile, sulphur-containing hydrocarbons in the room air and their possible inhalation (e.g. H2S or volatile thioethers dissolved in the distillate).
In the case of skin contact, no information is available on delayed effects after exposure. Skin irritation may occur on contact. The skin should be washed off immediately with plenty of water. Subsequent skin care is recommended. In case of contact with eyes, rinse thoroughly with plenty of water. Eye irritation does not necessarily have to occur. However, if the symptoms persist, a doctor should be consulted. After swallowing, rinse mouth and drink plenty of water. In this case, a doctor should be consulted.
In general, an exposed person should be brought into the fresh air, as gases containing sulphur (e.g. H2S or volatile thioethers dissolved in the distillate) can evaporate from the shale oil distillate. Immediately take off and remove soiled, soaked clothing.

Fire-fighting measures

Suitable extinguishing media:
foam
extinguishing powder
Carbon dioxide
Extinguishing media unsuitable for safety reasons:
Never use a sharp jet of water. Fire could be distributed with it.
Special hazards arising from the substance or mixture:
Sulfur dioxide (SO2) can be released in a fire.
Information for firefighters:
Do not inhale explosive or combustion gases.
Use self-contained breathing apparatus (insulating device).

Accidental release measures

Personnel not trained for emergencies:
- Keep people away and stay on windward side.
- Use personal protective equipment (safety glasses, gloves)
- Remove ignition sources, ensure adequate ventilation
Action force:
Material of the protective gloves should be suitable for handling hydrocarbons or non-polar substances (e.g. fluorocarbon rubber (Viton)). If necessary, wear hydrocarbon-resistant clothing and safety shoes.
Environmental protection measures:
Penetration into sewers or surface and groundwater must be avoided. The substance itself or washing water must not be discharged into the sewage system.
Methods and materials for retention and cleaning:
The substance should be prevented from spreading over large areas by suitable measures (e.g. covering the sewage system).
Take up substance with liquid-binding material (sand, sawdust) and collect in suitable containers for disposal. Store absorbed liquid for a longer period only in closed stainless steel containers.
Plastic materials are often unsuitable for long-term contact with the substance.

Handling and storage

Work with the material (e.g. sampling) may only be carried out in compliance with its strict enclosure (The substance is an on-site isolated intermediate and registered as such. One of the conditions is the strict containment of the substance in accordance with articles 17 (3) and 18 (4a) of regulation 1907/2006, so that strict exposure limitation is mandatory. Contact with the substance is unlikely under normal circumstances under these handling conditions. In the event of accidental release, first aid measures as well as fire-fighting measures and accidental release measure must be observed.).
Only work with sample quantities of the substance in the fume cupboard. Ensure good ventilation/suction.
Containers must be opened and handled with care, as extreme odour nuisance can occur if liquid vapours are released. After (laboratory) work, hands must be washed.
The substance should be handled in closed systems. It must be kept away from ignition sources. No smoking!
When storing large quantities, protective measures for release into the environment should be observed (e.g. floor trough without drain). In Austria storage in accordance with the regulation on flammable liquids (VbF BGBl. 240/1991) is mandatory (flash point > 55°C), taking hazard class AIII into account (observe possible succession regulations!).
The materials used for long-term storage purposes must be tested for suitability (stainless steel tanks). For samples (brown) glass containers are recommended. Tank farms must be equipped with appropriate retention devices.
Work on open containers must be excluded.
