| Handling and Storage | Back to Contents | 【Storage】
Keep away from sources of ignition. Store in a cool, dry place. Store in a tightly closed container. Corrosives area. | 【Handling】
Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Use only in a chemical fume hood. |
| Hazards Identification | Back to Contents | 【Inhalation】
May be fatal if inhaled. Causes chemical burns to the respiratory tract. | 【Skin】
Harmful if absorbed through the skin. Causes skin burns. | 【Eyes】
Causes eye burns. | 【Ingestion】
Harmful if swallowed. | 【Hazards】
Vapors form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. | 【UN (DOT)】
