The storage and transportation of ammonium thiocyanate (NH₄SCN) must strictly follow the physicochemical properties
The storage and transportation of ammonium thiocyanate (NH₄SCN) must strictly follow the physicochemical properties and safety regulations of chemicals. The following is a detailed operational guide:
I. Storage Conditions
Environmental Requirements
Temperature and Humidity Control: Store in a cool, dry environment (recommended temperature ≤25℃), avoiding high temperatures or direct sunlight.
Ventilation Measures: The warehouse must be well-ventilated to prevent the accumulation of vapor or dust.
Humidity Protection: Because ammonium thiocyanate is deliquescent, containers must be sealed to prevent moisture absorption, caking, or decomposition.
Container Selection
Use brown glass bottles or other light-shielding containers to store solutions, reducing the impact of photosensitivity.
Solid powders are recommended to be packaged in double-sealed plastic/metal drums to ensure air isolation.
Isolation Requirements
Incompatible Substances: Keep away from strong acids and strong oxidizing agents (such as lead nitrate and other hazardous substances) to avoid reactions that could cause danger.
Zoned Storage: Store separately from explosives such as potassium perchlorate to reduce the risk of accidental contact.
II. Transportation Regulations
Packaging Safety
When transporting liquids, containers should leave 5%-10% space to prevent leakage due to thermal expansion.
Seal all container openings and reinforce them (such as wrapping with tape) to ensure no leakage during transportation.
Environmental Control
Transport vehicles should be equipped with temperature control equipment to avoid decomposition or deterioration caused by high temperatures.
Avoid mixing with food, feed, etc. in the same vehicle to prevent cross-contamination.
Compliance Requirements
For export or cross-border transportation, confirm in advance whether it is a dangerous good and handle transportation certificates according to local regulations.
Post chemical labels and safety warning labels, clearly indicating emergency handling measures.
III. Precautions
Shelf Life Management: Ammonium thiocyanate solutions have a short shelf life and should be checked regularly and used preferentially.
Leakage Handling: In case of leakage, immediately isolate the contaminated area, collect it using inert absorbent materials, and avoid direct skin contact or inhalation of dust.
Emergency Protection: Wear protective clothing, goggles, and gloves during operation. Rinse immediately after contact and seek medical attention.
Summary
The storage and transportation of ammonium thiocyanate should combine its deliquescence, photosensitivity, and chemical activity characteristics, comprehensively control environmental conditions, and strictly follow safety regulations to reduce the risk of leakage, decomposition, or reaction.
