Signal Word: Warning
Hazard Statements: Causes skin irritation; causes serious eye irritation; may cause respiratory irritation depending on exposure
Precautionary Statements: Wash hands after handling; avoid breathing dust; wear suitable personal protection; avoid contact with eyes and skin; ensure good ventilation
Chemical Name: Fumaric Acid
Concentration: More than 98% in typical industrial or laboratory settings
Additives/Impurities: Minor quantities may include maleic acid or water, depending on manufacturing process
Inhalation: Move to fresh air; give oxygen if breathing becomes difficult; seek medical attention for persistent symptoms
Skin Contact: Remove contaminated clothing; wash skin with plenty of water and soap; consult physician if irritation develops
Eye Contact: Rinse immediately with lots of water for minutes while keeping eyelids open; remove contact lenses if present and easy to do; get medical advice if discomfort persists
Ingestion: Rinse mouth thoroughly; seek medical help if feeling unwell or if large amounts are swallowed
Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical powder, or foam
Unsuitable Media: Avoid high-pressure water streams that may spread powder dust
Specific Hazards: May emit acrid smoke and irritating vapors when heated or in fire; potential for carbon oxides release
Protective Equipment: Firefighters should wear full protective gear, including self-contained breathing apparatus, to avoid inhalation of combustion products
Personal Precautions: Avoid dust formation; use protective gloves, goggles, and mask; evacuate area if large spill
Environmental Precautions: Prevent runoff into drains, sewers, or surface waters
Methods for Clean-Up: Sweep up material without raising dust; place in approved waste containers for disposal; ventilate area after completion
Decontamination: Wash area thoroughly with water after bulk removal
Safe Handling: Work with proper ventilation; minimize dust generation; use local exhaust if needed; wash hands thoroughly after use
Storage Recommendations: Keep container tightly closed; store in a cool, dry, well-ventilated area; keep away from incompatible materials such as strong oxidizers and bases
Hygiene Practices: Do not eat, drink, or smoke near product; use clean work clothes and protective gear; segregate from food and feedstuffs
Exposure Limits: No specific OSHA or ACGIH exposure limits, but general dust limits apply (10 mg/m³ for nuisance dust)
Engineering Controls: Ensure local exhaust ventilation; use dust extraction with processes producing aerosols
Personal Protection: Wear safety goggles, chemical-resistant gloves, dust mask or respirator if high dust exposure expected; wear long sleeves and closed shoes
Environmental Controls: Avoid release to environment; maintain adequate housekeeping to minimize accumulation of powder on surfaces
