Fresh air, rest. Refer for medical attention.
First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Refer for medical attention .
Exposure can cause mild irritation to the mucous membranes. Symptoms may include coughing and shortness of breath. Ingestion of large doses may cause dizziness, abdominal pain, vomiting, bloody diarrhea, weakness, convulsions, and collapse. Contact with skin may cause irritation, redness, and pain. (USCG, 1999)

Use flooding amounts of water in early stages of fire. When large quantities are involved in fire, nitrate may fuse, or melt, in which condition application of water may result in extensive scattering of molten material.
Special Hazards of Combustion Products: Toxic fumes of nitrogen oxides are produced when heated to decomposition. Behavior in Fire: Contact with oxidizable substances may cause extremely violent combustion. (USCG, 1999)
In case of fire in the surroundings, use appropriate extinguishing media.
Sweep spilled substance into covered plastic containers. Wash away remainder with plenty of water.
Sweep spilled substance into covered plastic containers. Wash away remainder with plenty of water.
Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
NO contact with combustible substances or reducing agents. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Separated from combustible substances and reducing agents. Dry.Protect against physical damage. Store in cool, dry place; avoid storage on wood floors. Separate from combustible, organic or other readily oxidizable materials. Immediately remove and dispose of any spilled nitrate.

Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Wear safety goggles.
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
Use local exhaust or breathing protection.

The substance is a strong oxidant. It reacts with combustible and reducing materials. This generates fire and explosion hazard.

Oxidizing material. In contact with easily oxidizable substances it may react rapidly enough to cause ignition, violent combustion... Increases the flammability of any combustible substance.Mixtures of MAGNESIUM NITRATE with alkyl esters may explode owing to the formation of alkyl nitrates; mixtures with phosphorus, tin(II) chloride, or other reducing agents may react explosively [Bretherick 1979 p. 108-109]. Noncombustible but will accelerate the burning of combustible materials. If large quantities are involved in a fire or the combustible material is finely divided an explosion may result. Prolonged exposure to fire or heat may result in an explosion. Magnesium nitrate has been reported to undergo spontaneous decomposition in dimethylformamide [Bretherick 5th ed., 1995]. It tends to behave as a strong oxidizer.

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.

Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.Rinse contaminated clothing with plenty of water because of fire hazard.The recommendations on this Card also apply to Magnesium nitrate hexahydrate (CAS 13446-18-9) which is available commercially.
