au/incidents-injuries-emergency/procedures/lab#fire Spills- If a chemical spill is minor, all people near the spill should alerted, measures should be taken to avoid breathing in toxic fumes, and proper equipment should be worn and used while cleaning up the spill. If a chemical spill is major, any people who may have been contaminated need to battened to, the laboratory needs to be evacuated, and assistance should be called. If a spill is flammable, all heat and ignition shores should be turned off. Doors to the lab should be closed when the lab is evacuated. Fires- If a fire is minor, the lab should be alerted, the alarm should be triggered, and the flames should be smothered out with a fire blanket or proper fire extinguisher.

If a fire is major, the alarm should be triggered, the lab should be evacuated, the doors to the lab should be closed, and emergency response should be notified. Others- If a biological spill occurs, all efforts to avoid contamination should be made and proper safety measures should be implemented during clean up. If any person comes in contact with any kind of spill, exposed area should be washed with water and clothing should be removed. They should seek medical attention if necessary. All incidents should be reported to an advisor. Waste Disposal and Clean Up: No hazardous chemicals should be disposed in a sink, drain or solid waste containers that go to a landfill like trash cans.

  All hazardous waste should be labeled as hazardous waste. https://ehs.stanford.edu/topic/chemical-safety/chemical-waste-disposal
