SECTION 4: First-aid measures
4.1
Description of necessary first-aid measures
If inhaled
Fresh air, rest. Refer for medical attention.
Following skin contact
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .
Following eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Following ingestion
Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .
4.2
Most important symptoms/effects, acute and delayed
This material is highly toxic by ingestion, inhalation, or skin absorption. Very short exposure to small quantities may cause death or permanent injury. Following ingestion, mercuric oxide is readily converted to mercuric chloride, the most dangerous mercury compound. Mercuric oxide dust has a corrosive effect on eyes, skin, and respiratory tract. People with a history of allergies or known sensitization to mercury, chronic respiratory disease, nervous system disorders, or kidney disorders are at increased risk from exposure. (EPA, 1998)
4.3
Indication of immediate medical attention and special treatment needed, if necessary
Basic Treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and neat if necessary . Monitor for shock and treat if necessary . Anticipate seizures and treat if necessary . For eye contamination, flush eyes immediately with available water. Irrigate each eye continuously with normal saline during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal . Mercury and related compounds
SECTION 5: Fire-fighting measures
5.1
Suitable extinguishing media
If material involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use water in flooding quantities as fog. Use foam, dry chemical, or carbon dioxide.
5.2
Specific hazards arising from the chemical
When heated to decomposition (932F) it decomposes into mercury and oxygen. Fumes from fire may contain poisonous mercury vapor; oxygen may increase intensity of fire. Explosion of mercuric oxide may occur with friction or application of heat. Avoid reducing agents. Avoid light; may decompose into mercury and oxygen. Hazardous polymerization may not occur. (EPA, 1998)
5.3
Special protective actions for fire-fighters
In case of fire in the surroundings, use appropriate extinguishing media.
SECTION 6: Accidental release measures
6.1
Personal precautions, protective equipment and emergency procedures
Consult an expert! Personal protection: chemical protection suit. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT absorb in saw-dust or other combustible absorbents.
6.2
Environmental precautions
Consult an expert! Personal protection: chemical protection suit. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT absorb in saw-dust or other combustible absorbents.
6.3
Methods and materials for containment and cleaning up
Cleanup: Mercury removal from wastewater can be accomplished by these processes: BMS process; chlorine is added to the wastewater, oxidizing any mercury present to the ionic state. The BMS adsorbent (an activated carbon concentrated of sulfur compound on its surface) is used to collect ionic mercury. The spent adsorbent is then distilled to recover the mercury, leaving a carbon residue for reuse or disposal. TMRIMAC Process: wastewater is fed into a reaction whereby a slight excess of chlorine is maintained, oxidizing any mercury present to ionic mercury. The liquid is then passed through the TMRIMAC ion exchange resin where mercury ions are adsorbed. The mercury is then stripped from the spent resin with hydrochloric acid solution. Mercury compounds

SECTION 10: Stability and reactivity
10.1
Reactivity
10 mg/cu m (as Hg) Mercury cmpd (except (organo) alkyl compounds (as Hg)
Decomposes above 500°C . This produces highly toxic fumes including mercury and oxygen. This increases fire hazard. The substance is a strong oxidant. Reacts violently with reducing agents. Mixtures with metals and elements such as sulfur and phosphorus are shock-sensitive.
10.2
Chemical stability
Decomposes on exposure to air
10.3
Possibility of hazardous reactions
Flammable by chemical reaction. A powerful oxidizer.MERCURIC OXIDE is light sensitive. When hydrazine hydrate is dropped on mercuric oxide, an explosion occurs [Mellor 8:318. 1946-47]. Hypophosphorous acid reduces mercuric oxide explosively to the metal [Mellor 4:778. 1946-47]. When heated to decomposition (932 F) it decomposes into mercury and oxygen. Fumes from fire may contain poisonous mercury vapor; oxygen may increase intensity of fire. Explosion of mercuric oxide may occur with friction or application of heat. Avoid reducing agents. Avoid light; may decompose into mercury and oxygen. Fire risk in intimate contact with organic matter.

MERCURIC OXIDE
Mercury(II) oxide
Mercury oxide
Mercuric oxide, red
n/a
Mercury is an element with atomic symbol Hg, atomic number 80, and atomic weight 200.59; a heavy, silvery-white metal, liquid at room temperature, a rather poor conductor of heat and a fair conductor of electricity.
It is commonly known as quicksilver and was formerly named hydrargyrum.
Mercury is a nonessential trace metal that is a well known toxin, second only to lead as a cause of heavy metal poisoning.
Mercury is used in many areas of manufacturing and is present in dental and medical equipment. Because of the toxicity of acute and chronic exposure to metallic mercury, this metal is now used less and less in industry and attempts are made to remove it from household and medical equipment and appliances.
Oxygen is the chemical element with the symbol O and atomic number 8, meaning its nucleus has 8 protons.
Oxygen is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.
Dioxygen is used in cellular respiration and many major classes of organic molecules in living organisms contain oxygen, such as proteins, nucleic acids, carbohydrates, and fats, as do the major constituent inorganic compounds of animal shells, teeth, and bone.
Oxygen was isolated by Michael Sendivogius before 1604, but it is commonly believed that the element was discovered independently by Carl Wilhelm Scheele, in Uppsala, in 1773 or earlier, and Joseph Priestley in Wiltshire, in 1774.
