Laboratory Safety is a very important aspect of science. Without it, experimentation could result in very serious injury, if not death. To reduce the risks involved with experimentation, there are certain procedures that we should all follow as individuals and as a member of a group. It is important that the correct procedures are used in various situations, when handling hazardous or biological materials, when preparing, executing or cleaning up an experiment. It is also essential that you understand how to identify and use emergency equipment and protective gear. Show
Many laboratory guidelines are written based on experience – notably when things have gone badly wrong. Remember, you could be dealing with extremely dangerous and hazardous materials, so caution is required at all times. Many laboratory accidents and problems are due to haste. In the lab however, it’s important to take your time - not only for safety reasons, but also to avoid wasting samples, money and time. This training module is provided to guide you through and develop your understanding of Laboratory Safety. It is important to take your time to understand the procedures, concepts and reasons to make your laboratory as safe as possible. Outline

Chemical SafetyThe chemical safety program provides guidance and protocols to prevent injury to personnel, loss or damage to property, and ensures compliance with environmental regulations. Adherence to the basic principles of chemical safety reduces the risk of injury or chemical exposure. Chemical Materials - Common Types
Chemical - Incompatibilities
(Click or tap image for expanded view of table.) Chemical - Storage
Chemicals of Special Concern - Peroxide FormingA wide variety of organic compounds can spontaneously form peroxides on exposure to air. Peroxides are sensitive to heat, friction, and shock.
Chemical - Engineering ControlsChemical Fume Hoods are an important tool used to minimize exposure.
Prior to Using a Fume Hood
Chemical - Waste Disposal
Chemical - Spill Response
Biological SafetyBiosafety is the application of combining laboratory practices, procedures, facilities, and safety equipment to protect human health and prevent release of biological materials into the environment. Biological materials are defined as any biologically-derived materials which, either by accident or design, contain biological agents. Biological Materials - Common Types
Biological Safety - Institutional Biosafety Committee
Biological - ExposureMost common types of exposures:
Biological - Engineering ControlsBiological Safety Cabinets (BSC) are an important tool used to control bioaerosols and minimize exposure.
Biological - Waste DisposalBiohazardous waste includes the following general categories:
Never place chemicals, chemical bottles, radioactive materials, or other trash in biowaste containers. Waste containers for:
Biological - Spill Response
Radiological SafetyRadiation Safety is the science of protecting people and the environment from the harmful effects of ionizing radiation, which includes both isotope particle radiation and high energy electromagnetic radiation. Ionizing radiation can only be used in approved licensed laboratories. Radiological Materials - Common Types
Radiological - Institutional Radiation Safety Committee
Radiological - Exposure
Radiological - Incompatibilities
Radiological - Engineering Controls
Radiological - Waste Disposal
Radiological - Spill Response
Personal Protective Equipment
Gloves
Splash Goggles and Face Shields
Respirators
Lab CoatsLab Coats must be worn when there is potential exposure to:
Storage MethodPersonal protective equipment should be stored in a manner that protects the equipment from:
Eyewash and Shower Stations
Compressed Gas Cylinders
Liquid Nitrogen/Cryogenic
