Spill Cleanup Methods: Absorb spills with inert materials like sand or earth, collect in secure container for proper disposal, ventilate area, wash spill site after material pickup completed
Reporting: Report significant releases to local authorities
Handling: Avoid contact with skin and eyes, use appropriate personal protection, handle in a well-ventilated workspace or fume hood, keep containers tightly closed
Storage Conditions: Store in a cool, dry place away from heat or sources of ignition, avoid direct sunlight, segregate from oxidizing agents
Special Requirements: Use spill trays or secondary containment, ensure access to eyewash and safety shower
Incompatibilities: Strong oxidizers, strong acids
Exposure Limits: No occupational exposure limits established specifically for 2-Ethyl-3-Methyl Pyrazine
Engineering Controls: Use chemical fume hood or local exhaust ventilation for airborne vapours
Personal Protection: Nitrile or neoprene gloves, safety goggles or face shield, long-sleeved lab coat, NIOSH-approved respirator if vapours are present above safe levels
Hygiene Measures: Wash hands and face thoroughly before eating or drinking, remove contaminated clothing before leaving the work area

Acute Toxicity: Low oral and dermal toxicity expected, no classified acute hazard status based on current available data
Skin Contact: May cause mild irritation for sensitive individuals
Eye Contact: May cause stinging, redness, or discomfort
Inhalation: Exposure to vapours or mists may cause upper respiratory discomfort, coughing
Chronic Effects: No information suggests cumulative risk, limited evidence from long-term studies; always better to minimize repeated exposure
Mutagenicity, Carcinogenicity: Not listed as a suspect carcinogen by IARC, NTP, or OSHA. No mutagenic or reproductive toxicity data suggesting concern
Ecotoxicity: Relatively low concern for aquatic toxicity, proper control still matters due to possible taste and smell impacts to water systems
