Why Safety is Important!

Flinn Scientific's goal is to provide the necessary knowledge you need to successfully and safely teach science. We identify and discuss most common safety issues, providing logical and affordable solutions.


The Teacher's Duty of Care

Teachers are responsible for providing instruction, supervision, and a safe learning environment in their science classrooms.


Legal Foundation of Negligence

Negligence and liability are determined based on whether a teacher has followed the required duty of care.


Causes of Laboratory Accidents

Learn how to prevent accidents in the science lab by reviewing common causes of accidents and identifying responsible solutions to avoid these problems.


Legal Analysis—Teacher's Duty to Instruct and Warn

Teachers are responsible for demonstrating proper laboratory techniques and discussing potential safety hazards before laboratory activities.


Ideas to Demonstrate You Are a Responsible Science Teacher

Larry Flinn discusses how teachers can set the precedent that they have acted responsibly and proactively with respect to safety in the science lab.


Legal Analysis—Establishing the Teacher's Duty of Care

An in-depth look at specific case studies involving negligence.


Hazard Communication and the Laboratory Standard

Specific actions are required in order to properly follow both the Hazard Communication and the Laboratory Standards.


Laboratory Ventilation and Use of Fume Hoods

Laboratory ventilation must be well-designed, meet specific criteria, and be regularly tested for proper functionality.


Material Safety Data Sheets and Chemical Label Requirements

Material Safety Data Sheets require specific information, which can then be included on the chemical label.


Five-Minute Safety Inspection

This brief safety inspection ensures that the most crucial items in the science lab are in proper working condition.


Emergency Alert and First Aid

Emergency alerts and first aid procedures should be in place and practiced before the event of an accident.


Basic Principles of Toxicology

Toxicology depends on variables such as dosage and routes of exposure.


Relative Toxicity—Understanding and Assessing Risk

In order to understand toxicity it is important to understand the basic terminology and guidelines.


Reducing Exposure to Laboratory Chemicals

There are two main types of toxicity— acute and chronic. Avoid the effects of toxic chemicals by protecting yourself from exposure.


FAQ—Applying the Principles of Toxicology

Learn how to protect yourself against toxic chemicals and the steps regulatory agencies take to protect end users.


Goggle Safety

Proper eye protection that is suitable for a given activity should be worn in the laboratory at all times. This basic rule must be strictly enforced by the instructor.


Aprons, Gloves and other PPE

In addition to goggles, students and teachers must wear the necessary personal protective equipment in order to avoid exposure to laboratory chemicals.


FAQ—Proper Lab Attire

Tips on how to enforce the rule that proper lab attire is not optional, but required.


The Duty of Care to Provide and Maintain Safe Laboratory Facilities

The duty to provide a safe learning environment requires that teachers, administration, students, and parents work together.


Master Utility Controls

It is important to know how the water, electric, and gas shutoffs work in the laboratory.


Electrical Safety

Understand the safety precautions that apply to outlets, cords, and other electrical equipment.


Fire Blanket

Fire blankets have diverse applications that make them valuable for several safety problems in the science lab.


Fire Extinguisher

Choose a fire extinguisher based on your laboratory needs and learn how to properly operate the fire extinguisher.


Eyewash Requirements

An effective eyewash must provide a continuous flow of clean water to both eyes for 20 minutes.


Safety Showers

Essential safety equipment for the laboratory includes safety showers, which are offered in many forms.


FAQ—Lack of Proper Safety Equipment

A teacher may be found liable if the proper safety equipment is not provided for an activity in the laboratory or regular classroom.


The Duty to Supervise—Classroom Management Tips

These tips offer solutions for common classroom management issues so teachers can fulfill their duty of supervision.


How to Conduct a Safe Lab Activity

Teachers need to make sure students understand the common language of chemistry warnings. Teach this language using demonstrations.


Safety Guidelines for Chemical Demonstrations

Learn about the 12 safety guidelines for chemical demonstrations provided by the American Chemical Society.


Biology Lab Safety—Dissection and Microbiology

The biology lab can be hazardous too. Here are some proper procedures, instruments, and safe methods.


Glassware Safety

It's important to be aware of standard safety precautions that should be taken when using, heating, or handling glassware.


Chemical Purchasing Guidelines

Always ask yourself five simple questions before purchasing a chemical!


Procurement Procedures

Be informed and only select quality products from reliable suppliers.


Classroom Chemical Storage and Security

Chemicals must be stored under lock and key—there are no exceptions to this rule.


Dispensing Chemicals and Acid Safety

Chemicals should be bottled, dispensed, and stored properly.


Chemical Spill Control

Every science laboratory should be equipped with the proper materials to treat a chemical spill and the science instructor should be aware of proper cleanup techniques


Safety and Design of the Chemical Storeroom

Chemical storerooms should be properly designed and possess the necessary safety resources.


Chemical Storeroom Ventilation

Chemical storerooms should be vented to allow proper air exchange.


Chemical Storage—Storing Chemicals by Compatible Familes

Chemicals should be stored according to a logical and safe pattern known as compatible chemical families.


Chemical Treatment and Disposal Options

Promote methods to minimize hazardous waste by source reduction, reuse and recycling, and chemical treatment.


FAQ—Radioactive Waste

Learn about radioactive chemicals, how they can be properly stored, and options for disposal.


Licensed Hazardous Waste Disposal

Hazardous waste disposal companies should be EPA certified, provide reliable references, and give detailed and specific cost estimates ahead of time.


FAQ—Administration Won't Address Safety Concerns

The administration is more likely to address safety concerns when presented with well-organized, thoughtful facts.


How to Get Action—Developing a 3-Year Plan

Develop a detailed three-year plan that explains to the administration exactly what needs to be done to improve safety. It's not enough to identify problems—you must present solutions!
