Lead oxide

Lead oxide. It is yellow in color , which normally contains a little bit of minium , Pb ₂ O ₃ (double lead (II) oxide and lead (IV), red in color ) which gives the product an orange hue, commonly used in chemical and ceramic industry.

Hazards identification

Description of the emergency

POISON! DANGER! MAY BE FATAL IF SWALLOWED OR INHALED. OXIDIZER. CONTACT WITH OTHER MATERIAL MAY CAUSE FIRE. CAUSES IRRITATION TO SKIN, EYES AND RESPIRATORY AREA. NEUROTOXIN. AFFECTS THE FINE TISSUE OF THE RUBBER, THE CENTRAL NERVOUS SYSTEM, THE KIDNEYS, THE BLOOD AND THE REPRODUCTIVE SYSTEM.

• Health grade: 3 – Severe (life).
• Flammability rating: 0 – None.
• Reactivity Rating: 1 – Slight.
• Contact degree: 1 – Slight.
• Storage color code: Blue (health).

Potential health effects

• Inhalation: Lead can be absorbed through the respiratory system. Local irritation of the bronchia and lungs can occur and, in cases of acute exposure, symptoms such as metallic taste, chest and abdominal pain, and increased blood lead levels may follow.
• Ingestion: Symptoms of lead poisoning include abdominal pain and spasms, nausea, vomiting , headache. Acute poisoning can lead to muscle weakness, “lead line” in the gums, metallic taste, definite loss of appetite, insomnia , dizziness, high levels of lead in blood and urine with shock, coma and death in extreme cases.
• Skin Contact: Lead and lead compounds can be absorbed through the skin on prolonged exposure; the described symptoms of lead by ingestion show that it can poison. Periods of contact over short can cause local irritation and pain.
• EyeContact: Absorption can occur through tissues of the eye but the most common hazards are local irritation or abrasion.
• Chronic Exposure: Leadis a cumulative poison, and exposure to even small amounts can raise body contents to toxic levels. The symptoms of chronic exposure are like those of poisoning from ingestion; restlessness, irritability, visual disturbances, hypertension and gray facial color can also be observed.
• Provocation of pre-existing conditions: People with pre-existing kidney, nerve or circulatory disorders or with skin or eye problems may be more susceptible to the effects of this substance.

First aid measures

• Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
• Ingestion: Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person. Get medical attention.
• Skin contact: Clean skin immediately with soap and water for at least 15 minutes. Remove contaminated clothing and shoes. Get medical attention. Wash clothes before reuse. Thoroughly clean shoes before reuse.
• Eye contact: Immediately flush eyes with water for at least 15 minutes, lifting lower and upper eyelids from time to time. Get medical attention immediately.

Fire fighting measures

• Fire: Not fuel, but it is a mild oxidizing agent, which can increase the flammability of materials and fuels that come in contact with it.
• Explosion: Not considered to be a hazard.
• Extinguishing media: Use any suitable means to extinguish the surrounding fire. Do not allow water to enter drains or channels.
• Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated on pressure demand or other positive pressure mode. It can produce toxiclead fumes at elevated temperatures and also react with materials by oxidizing.

Accidental release measures

Ventilate area of ​​leak or spill. Put on appropriate personal protective equipment as specified in section 8. Spills: Sweep up for recovery or disposal. Vacuuming or wetting, sweeping can be good to avoid dispersion of dust.

Address and storage

Keep a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Insulator for incompatible substances. Areas in which exposure to lead metal or lead compounds may occur should be identified by samples or appropriate media, and access to the area should be limited to authorized persons. The containers of this material can be dangerous when they are empty since they conserve product residues (dust, solids); Observe all listed warnings and cautions for the product.
