Exposure Controls / Personal Protection of 2-Aminoethylamine:
Engineering Controls:
Use local exhaust ventilation or chemical fume hoods to maintain airborne concentrations below recommended limits.
Ensure emergency eyewash stations and safety showers are available.
Occupational Exposure Limits:
No specific OSHA PEL established for 2-Aminoethylamine.
Follow general amine exposure guidelines (e.g., TWA ~10 ppm [25 mg/m³] where applicable).
Personal Protective Equipment (PPE):
Respiratory Protection:
Use NIOSH-approved organic vapor respirators if ventilation is inadequate.
For high concentrations, use supplied-air or self-contained breathing apparatus.
Eye Protection:
Wear chemical safety goggles with side shields or a full face shield.
Skin Protection:
Use chemical-resistant gloves (nitrile, neoprene, butyl rubber) and protective clothing such as aprons, coveralls, and boots.
General Hygiene:
Wash hands, face, and exposed skin thoroughly after handling.
Remove contaminated clothing and wash before reuse.
Do not carry contaminated clothing home.
