There are three basic routes of disposal of laboratory chemical waste:
Sanitary sewer or trash disposal of non-hazardous materials;
Acid-base neutralization, followed by sewer disposal.
IUEHS management for offsite treatment or recycling – Campus-specific waste management procedures are found in Sections 5-7.
What are the types of laboratory waste?
Laboratory Waste
Recycling. Empty glass containers and bottles, aluminum cans, most plastic containers and bottles, and paper can be recycled.
Trash.
Laboratory Glassware Disposal Boxes.
Sharps Boxes.
Regulated Medical Waste Box.
What is the most effective method to treat solid lab waste?
Steam autoclaving
Where does lab waste go?
On college campuses, the waste generally gets transported to a central waste-handling location, where it is packed or combined for transport to a hazardous-waste incinerator.
Should lab windows be open Why?
Doors, Windows, and Walls. Doors should open in the direction of egress. Laboratories should not have operable windows, particularly if there are chemical hoods or other local ventilation systems in the lab.
What is the minimum distance from the front of the fume hood should you work?
4. The user’s unobstructed personal work area should extend at least 4′ 6” from the face of the fume hood. 5. The distance between the sash and an opposing wall or other obstruction likely to affect the air flow should be at least 6′ feet.
Why laboratory doors open outward?
Safety Reasons Many believe that doors which open outwards are safer as it allows for easier escape access. Anyone caught up in an emergency or fire, rushing to get away, would naturally push a door rather than pull it. They became crushed in the chaos as they fled for the exit doors and struggled to open them.
How do I know if my fume hood is working?
Check that the fume-hood is operating correctly before you start work. To check the air flow a strip of paper, tissue, or ribbon can be taped to fume-hood sash. Avoid cross drafts and disruptive air currents in front of the fume hood. Ensure that windows and doors near the fume-hoods are CLOSED.
