Storage Conditions

• Store in a cool, dry and well-ventilated warehouse.
• Keep bags tightly closed to prevent moisture absorption and caking.
• Avoid direct sunlight, high temperature and exposure to rain.
• Do not store together with strong acids or substances that may be affected by moisture.
• Use pallets and avoid direct contact of bags with the floor to maintain product quality.

Safety Precautions

Magnesium sulfate heptahydrate is generally considered to have low acute toxicity, but standard industrial hygiene practices should always be followed:

• Avoid inhalation of dust; use local exhaust ventilation where dust may be generated.
• Wear appropriate personal protective equipment (PPE) such as gloves, dust mask/respirator and safety goggles.
• Avoid prolonged or repeated contact with skin and eyes.
• In case of eye contact, rinse immediately with plenty of clean water for several minutes and seek medical advice if irritation persists.
• In case of skin contact, wash with soap and water.
• If large amounts are accidentally ingested or inhaled, seek medical attention.
• Keep out of reach of children and non-trained personnel.
