First-aid measures
Description of first aid measures
Call immediately a physician. Move the person away from the contaminated area, to breathe fresh air. If you think that fumes are still present, rescuers should wear an appropriate mask or self-contained breathing apparatus. Move the victim into stable side position to rest. If stop breathing, begin cardiopulmonary resuscitation (CPR). Mouth-to-mouth prohibited (possible intoxication of the rescuer). Put the victim in the recovery position (PLS). Keep the airway clear. Untied clothing such as a collar, tie, belt.
First aid for skin contact: Consult a physician. After skin contact , wash immediately with appropriate product and rinse with plenty of water (20-30 min). Remove contaminated clothing and shoes. Chemical burns must be treated promptly by a physician.
First aid for eye contact: Rinse with plenty of water holding the eyelids apart for 20-30 minutes.
First aid for ingestion: Consult a doctor immediately. If swallowed, rinse mouth with water (only if the person is conscious). Do not induce vomiting. Never give anything to drink.
Most important symptoms and effects, both acute and delayed
Symptoms / injuries after inhalation: Causes burns of the respiratory tract. In extreme cases, death may occur.
Symptoms / injuries after skin contact: Causes burns. Risk of serious irreversible damage
Symptoms / injuries after eye contact: Causes severe eye damage. Can cause blindness
Symptoms / injuries after ingestion: Abdominal pain. Nausea. May cause burning or irritation of the tissues of the mouth, throat, and gastrointestinal tract. In extreme cases, death may occur.
Indication of immediate medical attention and special treatment

Fire-fighting measures
Extinguishing Media
Suitable extinguishing media: Water spray, CO2, foam, powder
Inappropriate extinguishing media: Do not use a strong flow water
Special hazards arising from the mixture
Fire Hazard: Non-combustible. When heated.
Advice for firefighters
Protection in case of fire: Do not enter in fire area without protective equipment, including respiratory protection. Cool containers with water.
Other information: Wear protective clothing resistant to acid
Accidental release measures
Personal precautions, protective equipment and emergency procedures
For non-rescuers: No additional information available
For emergency: Preferably use chemical protection with respiratory protection
Environmental precautions
Do not discharge into the environment. Prevent product from entering drains. Dike with sand or earth (do not use combustible materials). Notify authorities if product enters into sewers or waters of public domain.
Methods and material for containment and cleaning up
Methods to cleaning up: Use personal protective equipment. Ensure adequate ventilation. Evacuate personnel to safe areas. Prohibit contact with skin, eyes and inhalation of vapors.
Handling and storage
Precautions for safe handling
Wear protective clothing and appropriate gloves (Please see Exposure control/personal protection section below). Avoid contact with this substance. Do not breathe gas, fumes, vapor or spray. If it exists an inhalation risk during the mode of use of the product, wear respiratory protective equipment. Avoid unnecessary exposure. Keep away from acids. Projections.
Hygiene measures: Do not eat, do not drink and do not smoke during use. Wash thoroughly hands after handling. Remove contaminated clothing and protective equipment before entering in a remediation area.
Handling and storage
Storage conditions: Store in accordance with local regulations. Keep only in the original container in a cool, well-ventilated area away from direct sunlight, incompatible materials and acids.Keep away from food, drink and animal feeding stuffs. Keep containers closed when not in use. Store in closed containers with closing up. Just put in a labeled container. Containers should be preferably made of stainless steel or reinforced plastics. Use appropriate container to avoid environmental contamination. Containers or packaging, even empty, can contain residue. Always follow the advice of hazard warnings and handle empty containers as if they were full containers. Do not use compressed air to empty the containers.

Exposure controls / personal protection
Sodium hydroxide 1310-73-2:
VLEP, weighted average over 8 hours: 2 mg/m3 in the air of workplaces
ACGIH, maximum exposure values (USA): 2 mg/m3 in the air of workplaces
Sodium sulfide 1313-82-2:
No data available
Sodium carbonate 497-19-8:
No data available
Control parameters:
If there is a mist, vapor or spray, local ventilation with fume hood aspiration is suitable. Use in closed process (e.g. transfer in closed circuit). Eye wash fountains and emergency showers should be installed close to any place where there is risk of exposure.
Hand protection: Use chemical resistant gloves according to EN 374:3. Seek advice from glove suppliers.
Eye Protection: Goggles mask or face shield with safety glasses according to EN 166.
Skin protection and body protection: Wear protective acid resistant according to EN ISO 17491-3: 2008. Boots.
Respiratory protection: In case of risk of excessive production of fog, wear a full face respirator with ABEK cartridge and P3 (EN 141) or SCBA and follow the manufacturer's instructions.
Control of Environmental Exposure: Avoid release to the environment. Waste water must be completely neutralized.
Stability and reactivity
Reactivity
Reacts with water. Reacts with metals, copper-zinc-aluminum (hydrogen formation), alkaline earth metal, acetaldehyde, acrolein, acrylonitrile, allyl alcohol (violent polymerization), halogenated hydrocarbon-maleic anhydride, nitroparaffin-bromine.
Contact with acid liberates hydrogen sulfide (H2S)
Chemical stability
Stable under the normal conditions of storage and handling
Possibility of hazardous reactions
See reactivity section below
Conditions to avoid
Contact with acid liberates hydrogen sulfide (H2S)
Incompatible materials
Acid, liberates hydrogen sulfide (H2S)
Hazardous decomposition materials
Sulfur dioxide. Contact with metallic substances may release flammable hydrogen gas.
Disposal considerations
This information apply to the product the way it is. User could reassess the product when he wants to dispose of it, because uses, transformations, mixtures and processes of the product may influence waste classification. Dispose of waste in authorized facilities for the treatment or disposal of (hazardous) waste in accordance with municipal, provincial and federal regulations in force.Do not throw away in trash. Empty containers could contain product residue and could be dangerous. Empty drums should be completely drained, properly bunged and promptly returned for repackaging. Treat package in the same manner as the product.
