Laboratory Safety

Laboratory Etiquette

All users must practice good housekeeping, make sure to clean-up after yourself, wash your glassware, be mindful of shared work spaces, and remember to not bring food or drinks into the lab. 

Personal Protective Equipment (PPE)

A sign is posted at every lab's entrance, please take a look to ensure you understand the requirements for entry. In order to enter a sample prep lab, you must wear safety glasses, closed toed shoes, and long pants. In addition to mentioned PPE, if you are working in the lab and there is a splash hazard, you must wear goggles instead of safety glasses, also use gloves, wear a lab coat (if applicable), and tie-up loose clothing and hair if necessary.

Emergency Protocol

Incident Card

All users must know the evacuation route and emergency assembly point (EAP), building evacuation plans are posted by exits.​ You must know what to do in case of​ life threatning emergencies (incident notification cards are provided at the badging office).

  • For life threatning emergencies like smoke, explosions, large hazardous material release, you must: Call 911, followed by calling ext. 5555, then notify your supervisor (Duty Operator or D.O.).
  • For non-life threatning emergencies like injuries: inform your supervisor (D.O.), followed by SLAC medical (M-F, 9AM - 5PM) or ext. 5555 if its after-hours (notify SLAC medical next bus. day).
  • For non-life threatning "off normal events" like equipment damage, near misses etc., first notify supervisor (D.O.) then call ext. 5555. 

Hazardous Waste

Sharps              Broken Glass          Waste Cabinet   

All waste produced in the Sample Prep Labs should be appropriately disposed of at SLAC. You are prohibited from transporting waste back to your home institution. Designated areas exist in the labs for sharps, broken glass, and hazardous waste, which must never be disposed of in the trash or sink drains.

Containment: Bottles, jars, and plastic bags are available for containing chemical waste. Place hazardous waste in an appropriately sized container and ensure it is tightly sealed. Separate solid waste from liquid waste (e.g. kimwipes from acid). Do not mix incompatible wastes (e.g. flammable solvent with oxidizer).

Labeling: All hazardous waste must be labeled, it must include chemical name and approximate concentration, physical state, relevant hazards, your name, the date, and the beamline or extension where you can be reached. It is important that you provide approximate concentrations for heavy metals such as lead, mercury, selenium, arsenic, chromium, cadmium, and silver.

Disposal: Once contained and labeled, hazardous waste should be placed into the lab’s hazardous waste cabinet. Waste should be segregated by hazard type into the appropriate bin.

Special Considerations: If you are producing large volumes of waste, please let us know before you begin your experiment.
