Guidance on Safe Use
Administrative data
First-aid measures
General advice:
If danger of loss of consciousness, place patient in recovery position and transport accordingly. Apply artificial respiration if necessary.
If inhaled:
After inhalation of decomposition products, remove the affected person to a source of fresh air and keep calm. Provide medical aid. Immediately inhale corticosteroid dose aerosol.
On skin contact:
Wash thoroughly with soap and water.
On contact with eyes:
Immediately wash affected eyes for at least 15 minutes under running water with eyelids held open, consult an eye specialist.
On ingestion:
Rinse mouth immediately and then drink plenty of water, induce vomiting, seek medical attention.
Note to physician:
Hazards: Risk of pulmonary edema. Symptoms can appear later. Danger of methaemoglobin formation after ingestion.
Treatment: Treat according to symptoms (decontamination, vital functions), treat with toluonium chloride to reverse methaemoglobinanaemia.
Fire-fighting measures
Suitable extinguishing media:
water
Unsuitable extinguishing media for safety reasons:
ABC powder, carbon dioxide
Specific hazards:
nitrogen oxides
The substances/groups of substances mentioned can be released in case of fire. Has a fire-promoting effect due to release of oxygen.
Special protective equipment:
Wear a self-contained breathing apparatus.
Accidental release measures
Personal precautions:
Use breathing apparatus if exposed to vapours/dust/aerosol. Avoid contact with eyes.
Environmental precautions:
Do not discharge into the subsoil/soil. Do not discharge into waterways or sewer systems without proper authorization.
Methods for cleaning up or taking up:
For residues: Pick up with suitable appliance and dispose of.
Handling and storage
Handling
Keep container tightly sealed. Breathing must be protected when large quantities are decanted without local exhaust ventilation. Processing machines must be fitted with local exhaust ventilation. Protect against moisture. Protect against heat. Do not mix with combustible substances. Handle in accordance with good industrial hygiene and safety practice.
Protection against fire and explosion:
The substance/product is non-combustible. Has a fire-promoting effect due to release of oxygen. Where required Prevent electrostatic charge - sources of ignition should be kept well clear - fire extinguishers should be kept handy.
Storage
Segregate from oxidizable substances. Segregate from acids. Segregate from ammonium salts.
Further information on storage conditions: Keep container tightly closed and in a well-ventilated place. This product is classified as a dangerous substance for storage. The authority permits and storage regulations must be observed. Keep away from food, drink and animal feeding stuffs.

Exposure controls / personal protection
Components with workplace control parameters
7632-00-0: sodium nitrite
7631-99-4: sodium nitrate
Personal protective equipment
Respiratory protection:
Breathing protection if dusts are formed. Particle filter with high efficiency for solid and liquid particles (e.g. EN 143 or 149, Type P3 or FFPE)
Hand protection:
Chemical resistant protective gloves (EN 374)
Suitable materials also with prolonged, direct contact (Recommended: Protective index 6, corresponding > 480 minutes of permeation time according to EN 374):
polyvinylchloride (PVC) - 0.7 mm coating thickness
nitrile rubber (NBR) - 0.4 mm coating thickness
chloroprene rubber (CR) - 0.5 mm coating thickness
Supplementary note: The specifications are based on tests, literature data and information of glove manufacturers or are derived from similar substances by analogy. Due to many conditions (e.g. temperature) it must be considered, that the practical usage of a chemical-protective glove in practice may be much shorter than the permeation time determined through testing.
Manufacturer's directions for use should be observed because of great diversity of types.
Eye protection:
Safety glasses with side-shields (frame goggles) (e.g. EN 166)
General safety and hygiene measures:
Handle in accordance with good industrial hygiene and safety practice. Do not breathe dust. Keep away from food, drink and animal feeding stuffs. No eating, drinking, smoking or tobacco use at the place of work. Take off immediately all contaminated clothing. Hands and/or face should be washed before breaks and at the end of the shift.
