Final answer:
Spill clean-up supplies and PPE are usually found in designated safety stations or clearly marked cabinets within the lab. It's important to know their locations and how to properly dispose of waste under the teacher's guidance, using established safety protocols.
Step-by-step explanation:
In a laboratory setting, spill clean-up supplies and personal protective equipment (PPE) are typically located in easily accessible areas, known to all lab users. It's important to know the location of these items beforehand, which can often be found in designated safety stations or clearly marked cabinets.
In the case of an accident or chemical spill, it's imperative to call your teacher immediately for assistance. Moreover, PPE should be used to protect oneself while handling chemicals and cleaning up spills, following the established safety protocols.
Disposing of waste chemicals is also a critical process that should be performed under the guidance of your teacher. Proper disposal methods ensure that chemicals do not end up down the sink, which could harm the environment.
Safety equipment like fire extinguishers and eyewash stations should also be known to all who partake in lab activities, as they are integral in addressing various emergency situations.
