1-methyl-2,3-dinitrobenzene should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid contact with skin, eyes, and clothing. Use non-sparking tools and equipment, as nitro compounds can be sensitive to impact or friction. Always follow good laboratory practices and consult the safety data sheet before handling.

1-methyl-2,3-dinitrobenzene should be stored in a cool, dry, well-ventilated area away from heat sources, direct sunlight, and incompatible materials. Keep containers tightly closed and protected from moisture. Store separately from strong reducing agents, metals, and organic materials to prevent potential reactions. Maintain storage temperatures below 25°C and ensure proper labeling. Use appropriate containment measures to prevent environmental release in case of container damage.

In case of skin contact with 1-methyl-2,3-dinitrobenzene, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15 minutes and seek medical attention. If inhaled, move the person to fresh air and monitor breathing. In case of ingestion, do not induce vomiting and seek immediate medical assistance. Always consult a physician and provide the safety data sheet.

1-methyl-2,3-dinitrobenzene must be disposed of in accordance with local, national, and international hazardous waste regulations.
