Important Safety Information About the ECD
Maintaining Your GC 229
When handling ECDs:
• Never eat, drink, or smoke.
• Always wear safety glasses when working with or near open ECDs.
• Wear protective clothing such as laboratory jackets, safety glasses, and gloves, and follow
good laboratory practices. Wash hands thoroughly with a mild nonabrasive cleaner after
handling ECDs.
• Cap the inlet and outlet fittings when the ECD is not in use.
• Connect the ECD exhaust vent to a fume hood or vent it to the outside. See the latest
revision of 10 CFR Part 20 (including Appendix B), or the applicable state regulation. For
other countries, consult with the appropriate agency for equivalent requirements.
Agilent Technologies recommends a vent line internal diameter of 6 mm (1/4-inch) or
greater. With a line of this diameter, the length is not critical.
