Special hazards arising from the substance or mixture:
Special exposure hazards arising from the substance or preparation itself, its combustion products, or released gases:
Ammonia gas may be liberated at high temperatures.
Ambient fire may liberate hazardous vapours.
Advice for firefighters:
Special protective equipment for firefighting:
Do not stay in dangerous zone without self-contained breathing apparatus.
In order to avoid contact with skin, keep a safety distance and wear suitable protective clothing.
Additional information on firefighting:
Prevent fire extinguishing water from contaminating surface water or the ground water system. Fire residues and contaminated fire extinguishing water
must be disposed of in accordance with local regulations.

Exposure controls / personal protection
Control parameters:
Dusts non-specific
Ireland
Long-term exposure value/ mg/m3: 10
Note: total inhalable
Source: Code of Practice for the Safety Health and Welfare at Work (2011)
Exposure controls:
Respiratory protection: Required when dusts are generated. Recommended Filter type: Half mask with a particle filter P2 (EN 143).
Hand protection: In heat treatment shops: Multi-layered, easily removable mittens with cuff. In storage areas: Impervious gloves
Unsuitable material: woven fabric
Reference substance: The selected protective gloves have to satisfy the specifications of EU Directive 89/689/EEC and the standard EN 374 derived from it. Take note of the information given by the producer concerning permeability and break through times, and of special workplace conditions (mechanical strain, duration of contact).
Eye protection: In heat treatment shops: Face shield made from self-extinguishing polycarbonate.
In storage areas: Safety glasses with side-shields
Skin and body protection: In heat treatment shops: Multi-layered protective clothing (no synthetic fibres): for example cotton fabric impregnated with Proban.
Note: Working clothes must not consist of textiles, which show a dangerous melting behaviour in case of fire.
In storage areas: Long sleeved clothing
General protective and hygiene measures:
Smoking, eating and drinking should be prohibited in the application area. Wash hands before breaks and at the end of workday. Handle in accordance with good industrial hygiene and safety practice.
Engineering measures: Provide sufficient air exchange and/or exhaust in work rooms.
