Recommended Use: Plant growth regulator for agriculture, horticulture, and research purposes
Manufacturer/Supplier: Refer to supplier or packaging for updated contact details
Emergency Contact Number: Available on product label or safety documentation
Classification: Not classified as a hazardous substance by GHS standards for dilute preparations, but concentrated material may cause irritation
Physical Hazards: Dust may create risk of slipping and airborne particles could irritate respiratory passages
Health Hazards: Causes mild skin and eye irritation, may trigger coughing if inhaled
Environmental Hazards: No major risks at recommended concentrations, higher doses in runoff could disturb aquatic systems
Signal Word: None required for non-concentrated use; caution advised
Hazard Pictograms: Not required at low concentrations
Precautionary Statements: Avoid contact with eyes, prolonged skin exposure, and direct inhalation of dust or powder
Active Ingredients: Gibberellin GA4 (chemical formula C19H24O5), Gibberellin GA7 (chemical formula C19H22O6)
Concentration: Usually formulated with both GA4 and GA7 in variable ratios (typically 1% each in commercial powders and liquids)
Other Components: May include water, fillers such as kaolin or lactose, and stabilizing agents
Impurities: Technical grade preparations may include trace solvent residues and unreacted biochemicals
Synonyms: Gibberellic acid GA4, Gibberellic acid GA7
Eye Contact: Rinse immediately with plenty of clean water, keeping eyelids open, continue rinsing for at least 15 minutes, seek medical advice if irritation persists
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, consult a doctor if rash or irritation develops
Inhalation: Move to fresh air, keep at rest, obtain medical attention if respiratory symptoms develop
Ingestion: Drink water to dilute, do not induce vomiting, seek medical help if feeling unwell
Notes for Doctors: Symptomatic treatment, no antidote known
Suitable Extinguishing Media: Use carbon dioxide, dry chemical or foam for small fires; water spray for large fires
Special Hazards: Decomposition in fire may emit carbon monoxide, carbon dioxide, organic fumes
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Additional Advice: Cool storage containers exposed to flames with water, retain contaminated runoff for disposal
Personal Precautions: Avoid breathing dust, ventilate area, wear protective clothing, gloves, and safety glasses
Environmental Precautions: Prevent spillage from entering drains, waterways, or soil
Cleanup Methods: Sweep up powder without creating dust, place in suitable sealed containers for disposal, wash spill site with water, ventilate area
Disposal: Dispose gathered material according to local regulations, avoid contamination of surface water
Handling: Work in well-ventilated areas, minimize dust generation and accumulation, wash hands after handling
Storage: Store in original, tightly closed containers in a cool, dry place away from sunlight, incompatible substances, and moisture
Storage Temperature: Keep below 30°C (86°F)
Incompatible Materials: Avoid storage with strong acids or alkalis
Container Requirements: Use only containers resistant to organic acids and properly labeled
Exposure Limits: No OSHA or ACGIH exposure limits established for GA4 or GA7
Engineering Controls: Use local exhaust ventilation to reduce airborne dust
Personal Protective Equipment: Safety glasses or goggles, protective gloves (nitrile or similar), laboratory coat or coveralls, respiratory protection if airborne concentrations rise
Hygiene Measures: Wash hands and face before eating, drinking, or leaving work area; avoid rubbing eyes
Appearance: White to off-white crystalline powder or suspension

Hazardous Reactions: No significant known dangerous reactions
Decomposition Products: Produces carbon oxides and organic compounds if burned or exposed to intense heat
Acute Toxicity: Low oral toxicity in mammals (LD50 > 2,000 mg/kg in rats)
Skin and Eye Irritation: May cause mild irritation, redness, or itching after direct contact
Inhalation Effects: Irritation possible if large quantities inhaled
Chronic Toxicity: No significant long-term effects found in studies at normal usage rates
Mutagenicity/Carcinogenicity: No evidence of mutagenic or carcinogenic action in available studies
Allergenic Potential: Low but not excluded for sensitive individuals
Aquatic Toxicity: Not acutely toxic to fish or aquatic invertebrates at expected environmental levels
Persistence and Degradability: Biodegradable, breaks down in soil and water via microbial action
Bioaccumulation Potential: Minimal, compounds do not persist in biological tissues
Mobility in Soil: Moderately mobile; runoff possible if overused
Waste Treatment Methods: Collect unused material in sealable containers for approved chemical waste disposal
