Protective Equipment for Firefighters: Wear self-contained breathing apparatus (SCBA), full protective gear
Firefighting Instructions: Contain firewater runoff for proper disposal, cool exposed containers with water spray to prevent pressure build-up, evacuate area if necessary
Personal Precautions: Ventilate area, eliminate ignition sources, use nitrile gloves, chemical splash goggles, and suitable protective clothing
Environmental Precautions: Prevent liquids from entering drains, surface waters, or soil
Methods for Containment and Clean-Up: Use inert absorbent material (such as sand), collect and store in approved chemical waste containers, decontaminate area with detergent solution
Notification: Report significant spills to local authorities as per chemical release regulations
Decontamination: Wash all exposed surfaces thoroughly after cleanup
Handling: Work in well-ventilated area, keep away from open flame and heat sources, avoid prolonged or repeated skin contact and inhalation of vapors, use protective equipment without exception
Storage: Keep container tightly closed in a dry, cool area, out of direct sunlight, use only containers that are chemical-resistant and approved for monomer storage, store away from oxidizing agents, acids, and sources of ignition
Stability of Product: Store with stabilizer (polymerization inhibitors) intact, monitor condition of stabilizer periodically
Temperature Requirements: Recommended storage temperature between 2°C and 8°C to slow polymerization
Engineering Controls: Local ventilation or exhaust system recommended for all handling and transfer operations
Occupational Exposure Limit Values: No occupational exposure limit specified for BDGMA, monitor exposure to ensure airborne concentrations remain low
Respiratory Protection: Use organic vapor respirator when airborne concentrations may exceed recommended values or in cases of spill
Hand Protection: Nitrile or neoprene gloves provide barrier against permeation, check gloves regularly for degradation
Eye Protection: Chemical splash goggles meeting ANSI Z87.1 or EN166 standards
Skin and Body Protection: Wear lab coat, apron, or chemical-resistant clothing where splashing possible
Hygiene Measures: Do not eat, drink, or smoke in work area; wash hands thoroughly after use

Vapor Density: Heavier than air (estimated based on molecular weight)
Solubility(ies): Slightly soluble in water, miscible with most organic solvents
Partition coefficient (n-octanol/water): No published value, high log Kow expected due to ethylene glycol and butyl chain

Viscosity: 8-15 mPa·s at 25°C
Auto-Ignition Temperature: Not determined
Chemical Stability: Normally stable under recommended conditions with inhibitor present

Acute Toxicity: Oral LD50 (rat): >2000 mg/kg, Dermal LD50 (rabbit): >2000 mg/kg
Skin Corrosion/Irritation: Causes moderate skin irritation with prolonged exposure
Eye Damage/Irritation: May result in redness, tearing, blurred vision
Respiratory Sensitization: Extended inhalation exposure can lead to upper respiratory tract irritation
Skin Sensitization: Documented in laboratory and industrial experience, allergic response possible on repeated contact
Carcinogenicity: Not identified as a human carcinogen by IARC, NTP, OSHA, or EU CLP
Mutagenicity: Not expected to be mutagenic at environmental concentrations, limited evidence in available literature
Reproductive Toxicity: No known reproductive risks in available data, but avoid exposure during pregnancy as a workplace control measure
Target Organ Effects: Skin, eyes, respiratory tract at high doses or repeated exposure
Aquatic Toxicity: Moderately toxic to aquatic organisms, LC50 (fish, 48h): 10-50 mg/L range
Persistence and Degradability: Biodegradable in environmental conditions, but polymerization reduces breakdown rate
Bioaccumulative Potential: Potential for bioaccumulation exists based on log kow; water solubility limits exposure
Mobility in Soil: Can leach into groundwater if released in bulk quantity, but binds to organic components in soils
Other Adverse Effects: Avoid release to the environment based on aquatic ecosystem data, inform water authority if large spill occurs
Waste Treatment Methods: Cured (polymerized) product may be handled as non-hazardous waste, uncured residues require disposal by licensed hazardous waste contractor
Disposal of Packaging: Rinse empty containers three times with suitable solvent, offer for reconditioning if possible, follow local regulatory guidelines
Sewage Disposal: Never drain chemical to sewers; notify water treatment facility if unintentional release occurs
Contaminated Containers: Label and store with same precautions as bulk material until thoroughly decontaminated
Recycling and Recovery: Feasible with cured materials; consult local manufacturer or supplier collection schemes for recycling options
