Substance: Glycidyl Methacrylate
Synonyms: GMA
Chemical Formula: C7H10O3
Chemical Family: Methacrylates
Common Uses: resin manufacturing, adhesives, specialty coatings, plastics, ink additives
Physical State: Colorless to pale yellow liquid
Odor: Sharp, irritating
Routes of Exposure: Inhalation, skin contact, eye contact
Main Hazards: Sensitization, irritation to eyes, skin, respiratory tract; may damage the nervous system; flammable liquid and vapor
Chronic Health Risks: Frequent or prolonged exposure can lead to skin sensitization, possible allergic reactions, damage to internal organs through repeated exposure
Label Elements: Flammable, irritant, health hazard. Symbols match recognized international standards.
Glycidyl Methacrylate: Typically above 95% by weight in technical grade
Stabilizers: Trace added to reduce unwanted polymerization; methyl ether of hydroquinone is common
Possible Impurities: Trace methacrylic acid, oligomers
Inhalation: Remove to fresh air, seek medical attention if symptoms like cough or headache develop
Skin Contact: Remove contaminated clothing, wash exposed skin thoroughly with soap and water
Eye Contact: Flush eyes with water for several minutes, remove contact lenses if present, consult physician right away
Ingestion: Do not induce vomiting; rinse mouth thoroughly, seek immediate medical guidance
Symptoms to Watch: Redness, rash, burning sensation, nausea, dizziness
Suitable Extinguishing Media: Use foam, dry chemical, or carbon dioxide
Hazards from Fire: Vapors form explosive mixtures with air, combustion may produce toxic gases including carbon monoxide and carbon dioxide
Protective Equipment for Firefighters: Full protective gear including self-contained breathing apparatus
Fire and Explosion Precautions: Cool containers near fire with water spray
Personal Protection: Avoid inhalation and direct contact, wear gloves, goggles and suitable respiratory protection
Spill Response: Evacuate area, ventilate, eliminate ignition sources, contain spill with inert absorbent (e.g., sand), collect in labeled containers for disposal
Clean-Up: Wash the spill site with soap and water after material pickup
Environmental Precautions: Prevent run-off into drains, surface water, or soil
Handling: Use only in well-ventilated areas, avoid all sources of ignition, wear personal protective equipment, avoid skin and eye contact
Storage: Store in cool, dry place, protect from light and moisture, keep tightly sealed in containers made of compatible materials (e.g., stainless steel), segregate from oxidizing agents, acids, bases
Special Notes: Ensure containers are clearly labeled, regularly check for leaks or signs of degradation
Engineering Controls: Local exhaust ventilation, explosion-proof electrical installations
Respiratory Protection: Appropriate respirators for airborne concentrations over recommended limits
Hand Protection: Nitrile, neoprene gloves
Eye Protection: Safety goggles or face shield
Skin Protection: Chemical-resistant clothing (lab coat, apron), closed footwear
Hygiene Measures: Wash hands after handling, avoid eating, drinking, or smoking during use
Appearance: Clear to light yellow liquid
Odor Threshold: Noticeable at low levels
Boiling Point: Around 189°C
Melting Point: Less than -60°C
Flash Point: 75°C (closed cup)
Vapor Pressure: Low at ambient temperature
Density: ~1.07 g/cm³
Solubility: Limited in water, miscible with most organic solvents
Viscosity: Medium, flows easily at room temperature
Stability: Stable under recommended storage conditions
Reactive With: Strong oxidizers, acids, bases
Hazardous Decomposition Products: Carbon oxides, irritant fumes
Polymerization: May occur if heated, exposed to light, or contaminated with certain substances; always use inhibitors to prevent dangerous runaways
Conditions to Avoid: Heat, sunlight, static discharge, incompatible materials
Acute Exposure Effects: Causes skin and eye irritation or burns, respiratory irritation; ingestion harmful
Chronic Exposure Effects: Allergic skin reactions, risk of asthma-like symptoms, potential nervous system effects with sustained contact
Sensitization: GMA frequently triggers skin sensitization, especially after repeat exposure
Carcinogenicity: No current evidence for human carcinogenicity supported by major regulatory agencies
Distribution: Volatile and water-insoluble, mainly environmental concern for aquatic compartments
Acute Toxicity: Harmful to aquatic organisms, unpredictable effects if released in large amounts
Persistence and Degradability: Limited data on long-term persistence in soil or water; breaks down slowly under environmental conditions
Bioaccumulation: Not likely to bioaccumulate significantly, though high local concentrations can impact sensitive species
Waste Handling: Collect liquid waste in properly labeled containers
Disposal Methods: Incinerate in licensed facility, do not pour down the drain or discard in regular trash
Special Precautions: Waste must be treated as hazardous due to its reactivity and environmental effects
Proper Shipping Name: Glycidyl Methacrylate
Transport Hazard Class: Flammable Liquids
Packing Group: II (moderate risk)
Special Precautions: Protect from physical damage, restrict access to trained personnel during transit, use only approved containers with clear hazard labels
Listed Under: Chemical inventories in the US, EU, and other major markets
Notable Restrictions: Handling and disposal governed under hazardous substance control policies; most regions require training and formal risk assessment before use
Labeling Requirements: Strong hazard warnings, specific pictograms, reference to skin sensitization and flammability risks
Reporting Obligations: Large users and manufacturers submit regular usage and emission data to responsible authorities
Community Right-to-Know: Glycidyl Methacrylate falls under regional laws aimed at making chemical risks transparent to workers and neighbors
