Administrative data
First-aid measures
1. Description of first aid measures
- Inhalation:
No particular measures required.
- Ingestion:
Drink plenty of water (in case you feel unwell consult doctor).
- Skin contact:
Dust has to be rinsed with water (if irritation persists contact doctor).
- Eye contact:
Dust has to be rinsed with water (if irritation persists contact doctor).
- Notes for the doctor:
No allergic reactions known, mineral dust.
2. Most important symptoms and effects, both acute and delayed
- skin and eye irritation might occur
3. Indication of any immediate medical attention and special treatment needed
- not appropriate
Fire-fighting measures
1. Extinguishing media
- The substance is not combustible. Use any means suitable for extinguishing surrounding fire.
2. Special hazards arising from the substance or mixture
- none
3. Advice for fire fighters
- not appropriate
Accidental release measures
1. Personal precautions, protective equipment and emergency procedures
- avoid creating airborne dust wherever possible
- see section below Exposure controls / personal protection for personal protection
2. Environmental precautions
- avoid creating airborne dust wherever possible
- see section below Disposal considerations for waste disposal
3. Methods and material for containment and cleaning up
- Spills: Sweep together and containerize for reclamation or disposal. Dry vacuum or wet cleaning with mechanical devices may be used to avoid dust dispersal.
Handling and storage
1. Precautions for safe handling
- avoid creating airborne dust wherever possible
- do not eat, drink and smoke in working areas
- wear appropriate protective clothing (e.g. goggles, gloves)
- avoid prolonged skin contact
- wash hands after work
2. Conditions for safe storage, including any incompatibilities
- no special requirements
3. Specific end use(s)
- not applicable

Additional information
- Special provisions / remarks / other:
- Not a dangerous good according to the regulations ADR, IMDG and IATA
Exposure controls / personal protection
1. Control parameters:
- not applicable referring to European values
2. Exposure controls:
- appropriate engineering controls:
-- for closed cycles: care for dedusting installations
-- for semi-closed and open cycles: care for sufficient ventilation or wetting the ash
- individual protection measures:
-- Eye / face protection:
Safety goggles / face shield if potential for contact is existing
-- Skin (hand) protection:
Gloves if potential for contact is given; further measures for body protection are usually not necessary
-- Respiratory protection:
No special protective equipment required if dust occurs constantly – use respiratory dust mask
Stability and reactivity
1. Reactivity
- no reactivity hazards
2. Chemical stability
- stable under normal conditions
3. Possibility of hazardous reactions
- not applicable as material is not hazardous and no reactivity hazards are to be expected
4. Conditions to avoid
- no special requirements
5. Incompatible materials
- no incompatible materials known
6. Hazardous decomposition products
- not applicable as no hazardous properties
Disposal considerations
1. Waste treatment methods
Ashes (residues), coal have to be disposed off by national regulations for non hazardous wastes; no further special treatment methods are necessary
