Lab safety etiquette around reference standards
PPE, fume-hood protocol, waste handling, and incident-response habits that keep a reference-standard bench safe and reproducible.
Personal protective equipment
- Nitrile gloves, lab coat, and safety glasses for all reconstitution and aliquotting work.
- Switch gloves between handling different reference standards to avoid cross-contamination.
Workstation and fume hood
Reconstitute and aliquot inside a certified fume hood when working with powders. Wipe down the bench with isopropyl alcohol between runs, and never eat or drink at the analytical bench.
Waste handling
Empty vials, septa, syringes, and used aliquot tubes go into your institution's biohazard or chemical-waste stream per the SDS for the molecule. Do not rinse and reuse single-use consumables.
Incident response
A spilled lyophilizate is contained with a damp wipe rather than a dry one (less aerosolisation). Skin contact is rinsed with copious water; document the incident in your lab's logbook.
