The product is a mixture consisting of several chemicals as described above. Even though each ingredientsalone may be hazardous or harmful, the product mixture itself is a moderately viscous paste. The product isdelivered, transported and stored in cans with appropriate net contents of 1.5kg, and the purpose and placeof use of the product is isolated from the general public’s living environment. It is applied as anti-seize agent
to spaces between metallic bolt and nut in a reasonable amount. Unlike oils, it will not flow out or leak.
Virgin products are hermetically sealed. Although the main ingredient trilead tetraoxide itself is a fine
powder with an approximately 3μ diameter and may cause pneumoconiosis, the product causes no suchhazard.

Mineral oils used as ingredients are kneaded and hardened to such a degree that the flash point is muchhigher than the original ones. Without massive fire, the product will not ignite by itself.

Physical changes of SMOCON with heating
200 ℃:Gas and oily smoke generation resulted from vaporization of oil ingredients.

230 ℃:

Gas starts igniting.

500 ℃

:

Pb3O4 transforms into PbO. Molten lead generates, releasing oxygen.

Hazards: Fire Defense Law :Toxicity:

Non-hazardous material

Acute toxic substance, other hazardous substances.
Trilead tetraoxide is regulated by the Regulations regarding Lead Poisoning Prevention. However,since the product contains it in the oil phase and the purpose and place of use of the product areunlikely to cause health hazards orally, acute poisoning is also unlikely. Chronic poisoning is noSMO-H-27-2 Rev.3 3/7

concern because the exposure level is low and the exposure time is short.

EyeFirst-aid Measures:
Immediately flush eyes with plenty of running water for at least 15 minutes.

Seekophthalmologist’s assistance if irritation persists.
Skin

Flush skin with plenty of soap and then water.

Inhalation-Ingestion

Sputter and wash the mouth. In case of putting material into the mouth accidentally,swallowing is unlikely to occur physiologically. Spit all out and get medical aid.

Section 5.

Fire Fighting Measures:

Use extinguishing media immediately. Move container to a safe place. In case of immovable, sprinkle water
to containers and adjacent to keep them cool.

Section 6.

Accidental Release Measures:

SMO-H-27-2 Rev.3 4/7

Because of use of standard, appropriate-size containers to transport and store the material andeconomically controlled amount of stock, massive leakage is unlikely. In case of light leakage, wipe spillwith cloth or paper and solvent, such as gasoline. In case of massive leakage, collect material with shovel
and dispose in proper way.

7. Handling and Storage:
Handling: Wear gloves to avoid direct contact during handling, and wash your hands with appropriate
solvent after handling.
Storage:

Proper amount of the product is put and tightly closed in standard-size container thatcontains a modest amount. Store residue in a tightly closed container.

Keep away fromsources of ignition and inflammable materials.

8. Exposure Controls and Personal Protection:
Administrative levels:

0.05 mg/m³(as Pb)<According to Work Environment Assessment Standard, Appendix as of Feb 17, 2017>(Announced by Ministry of Health, Labor, and Welfare Notification No.79 in Sep, 1988)
Permissible Limit:-Protective equipment:

Note: Trilead Tetraoxide (Pb3O4) is produced via lead monoxide (PbO) by combustion (oxidation) of lead(Pb). The oxidation temperature of PbO and the decomposition temperature of Pb3O4 are so close, thus,
Pb3O4 that has been produced decomposes into PbO when temperatures are too high.
Pb+O → PbO

3PbO+O → Pb3O4

2Pb3O4 → 6PbO+O2

For this reason, products made from Pb3O4 also contain PbO.
