Description of necessary first-aid measures
Fresh air, rest. Refer for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Do NOT induce vomiting. Give nothing to drink. Refer for medical attention .
Most important symptoms/effects, acute and delayed
Causes burns on mucous membrane and skin. Inhalation of dust causes sneezing. (USCG, 1999)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Remove patient from contact with the material. Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Inorganic Bases/Alkaline Corrosives and Related Compounds/
SECTION 5: Firefighting measures
Suitable extinguishing media
Extinguish fire using agent suitable for surrounding fire. Use flooding quantities of water as spray. DO NOT use carbon dioxide or halogenated extinguishing agents.
Specific hazards arising from the chemical
Excerpt from ERG Guide 157 [Substances - Toxic and/or Corrosive (Non-Combustible / Water-Sensitive)]: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. For UN1796, UN1826, UN2031 at high concentrations and for UN2032, these may act as oxidizers, also consult ERG Guide 140. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Substance may react with water (some violently), releasing corrosive and/or toxic gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. (ERG, 2016)
Special protective actions for fire-fighters
In case of fire in the surroundings, use appropriate extinguishing media.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered dry containers.
Environmental precautions
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered dry containers.
Methods and materials for containment and cleaning up

SECTION 10: Stability and reactivity
Reactivity
The solution in water is a medium strong base. Reacts with water. This generates sufficient heat to ignite combustible materials. Reacts violently with acids, halogens and metals.
Chemical stability
Readily absorbs carbon dioxide and water from air, becoming airslaked.
Possibility of hazardous reactions
Not combustible, but bulk powder may heat spontaneously when damp with water.A base and an oxidizing agent. Neutralizes acids with generation of heat. Nonflammable, but will support combustion by liberation of oxygen, especially in the presence of organic materials. Reacts very violently with liquid hydrofluoric acid [Mellor 2, Supp. 1:129 1956]. Reacts extremely violently with phosphorus pentaoxide when reaction is initiated by local heating [Mellor 8 Supp.3:406 1971].
Conditions to avoid
no data available
Incompatible materials
Addn of water to quicklime has generated temp as high as 800 deg C. Some reports describe reaction as violent. Ignition of sulfur, gunpowder, wood, and straw by heat of quicklime-water reaction has been reported.
