  2. 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!

  3. 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.

  4. 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.

  5. 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.

  7. 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.

  8. 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.
