inflammable gas; specific density is 0.08987; hard to liquidify; explosion limit is 4.15-73% in the air; at room
temperature, it's relatively inert; upon combustion, it can react with many metals and nonmetals directly;
combustion with high heat and blue flame.
2. Applications:
for the production of hydrochloride acid, hydrogenated oils, artificial
gasoline, synthesis of methanol, hydroborates of metals, and many more;
as reductant for organic intermediates, in metallurgy, and other fields.
3. Quality spec:
conforms to GB/T3634-95

4. Important Notice:
Hydrogen is highly explosive and inflammable gas. Must comply with the "Supervisional Regulations on
Cylinder Safety" and avoid fire during transportation and use. Do not mix with other inflammable substance
during transportation. Must handle with care. Avoid exposure under burning sun. The transport vehicle shall
have clearly marked signed that say "Danger!". Store in well ventilated, specifically designed storage far away
from sources of fire and heat.
