LAB SAFETY The important general safety rules that you need to know…
Safety Introduction • Safety and health rules and regulations should be understood and practiced by everyone. This is true whether you are at school, work, or home. • Safety is defined as action taken to prevent or reduce the possibility of personal injury. • Health is defined as freedom from physical disease or pain. • The roles of safety and health are the same no matter where you are. Safety and health rules protect you and those around you from injury. • Safety and health is the responsibility of EVERYONE!
Safety Laws • Safety is a serious matter. • There are state and federal laws to enforce safety standards. • The Occupational Safety and Health Act of 1970 is a law that governs federal safety standards. • This law created the Occupational Safety and Health Administration, or OSHA, to assure that every working person is in a safe and healthful working environment.
Safety Laws • Setting standards and inspecting workplaces are some of the functions of OSHA. • One important OSHA standard is the Hazard Communication Standard. • This is a set of rules for any business or school that uses chemicals or other substances that can be a safety risk.
Safety Laws • This standard requires that a school or company keep on file a Material Safety Data Sheet (MSDS) for each hazardous substance. • This form contains the name of the chemical, safe exposure levels, explosion and health hazard information, and precautions for safe use, disposal methods, and first aide treatment information. • Many state laws are similar to the OSHA standards.

Protecting Your Eyes… • Much of what you learn is by sight. • Since you only have one pair of eyes, take precautions to protect them. • One of the most common times when eyewear protection is necessary in a materials and processes lab is when you are operating tools and machines, and handling and mixing chemicals. • Safety glasses should be worn at ALL TIMESwhen you are involved in these activities. • In all cases of eye contact with chemicals, flood the eye with water immediately, continuously and gently for at least 15 minutes.
Protecting Your Eyes… • The American National Standards Institute (ANSI) has developed standards for safety eyewear. • The standard for safety eyewear is ANSI Z87 and safety eyewear that meets this standard is stamped Z87.

General Safety Practices • General safety practices involve using common sense. Safety practices can be broken down into several sub-areas. • Conduct • Personal Attire • Equipment and Tool Use • Using Electricity • Handling Chemicals and Other Liquids • Maintenance
Conduct • Refers to the correct behavior in the appropriate place and at the appropriate time. • The way you conduct yourself in various situations involves using common sense and good judgment. • Unsafe conduct can endanger everyone and will result in dismissal from the lab.
Rules For Proper Conduct • Know the safety rules and follow them. • The lab and its equipment should be used only when the teacher is present. • Disruptive behavior will not be tolerated in the classroom. • Report unsafe conditions immediately. • Unsafe actions such as running or throwing objects will not be permitted. • Chairs or stools should never be leaned back or tilted back while sitting in them. Falls can result in serious head or back injuries.
Personal Attire • Refers to the clothing and protective devices that should be worn for the activity you are doing. • Accidents can result when clothing becomes caught in machinery or when chemicals splash.
Rules For Personal Attire • Use approved safety glasses or goggles when needed. • When staining or painting, wear a lab coat or apron to protect clothing. • Secure loose clothing and hair. • Open toed shoes should NOT be worn in the Lab.

Equipment and Tool Use • Refers to how you should handle and use tools. • Tools and equipment make our task easier, but you must understand how to use them
Rules For Equipment and Tool Use • Use tools and equipment only after a demonstration and or safety check. • Never use equipment that is out of order. If a machine does not seem to be working properly, tell the teacher. • Be careful when using sharp tools. Keep the points turned away from you and others.
Using Electricity • Many of the tools and equipment that we use are powered by electricity. • Electrical shock can be fatal.
Rules for Working Around Electricity • Do not use equipment with damaged or exposed electrical wires. Should you see this report it IMMEDIATELY. • Equipment should be grounded. • Never use electrical equipment on a wet surface. • Do not touch electrical switches or equipment with wet hands.
Handling Chemicals and Other Liquids • Chemicals are necessary in many school and work environments. • Treat chemicals with respect. Tech. Ed.
Rules for Working With & Around Chemicals • Spilled liquids should be wiped up immediately to avoid slipping. • Keep your hands away from your eyes when using chemicals. Wash your hands after using chemicals. • Know the procedures for washing your eyes in case they are exposed to a chemical. • Identify the contents of bottles and containers by label. • Know the formula and mixing procedure before handling chemicals.
Maintenance • Improves the appearance of the working area, but more importantly, it makes it safer. • Accidents often occur in areas that are dirty, cluttered, and unsanitary.
Rules for Maintenance • Thoroughly clean your work area at the end of each class. • Tables, counters, and sinks should be clean. • Store materials, projects, and equipment in approved locations. • Floors must be kept free of objects or materials that might cause falls. • Aisles should be kept clear at all times.
Fire Safety • You should be familiar with the procedures to follow in case of a fire. • Your teacher or another adult should be notified immediately. • Know how to exit the building.
Fire Classifications • Type A fires involve combustible materials such as wood, paper, or cloth. • Type B fires involve flammable liquids such as solvents and oil. • Type C fires involve electrical equipment.
Fire Extinguishers • Fire extinguishers are labeled to show what type of fire they can extinguish. • Fire extinguishers in schools are a type ABC. This allows them to be used on any type of fire.
How to Use Fire Extinguishers • If you must use a portable fire extinguisher, use the PASS method • Pull the pin • Aim low • Squeeze the handle. • Sweep from side to side.
In Case Of an Accident • Make sure you are familiar with steps that must be followed in case of an accident. • All accidents, no matter how slight, should be reported to the instructor immediately. • The school nurse or another qualified person should treat any injuries as soon as possible.
If the Teacher is Hurt… • Stop and turn off all tools and machines IMMEDIATELY • Listen for guidance from the teacher and follow all directions that are given.
