MSDS Hazard Diagram Health Flammability Reactivity Special Concerns

 Category One - Health (Blue)  4 - Can cause death or major injury despite medical treatment.  3 - Can cause serious injury despite medical treatment.  2 - Can cause injury. Requires prompt treatment.  1 - Can cause irritation if not treated.  0 - No hazard.Category  Two ­ Fire (Red)  4 - Very flammable gases or very volatile flammable liquids.3 - Can be ignited at all normal temperatures.  2 - Ignites if moderately heated.  1 - Ignites after considerable preheating.  0 - Will not burn.

Special Category Three ­ Reactivity (Stability) (Yellow) 4 - Readily detonates or explodes. 3 - Can detonate or explode but requires strong initiating force or heating under confinement. 2 - Normally unstable but will not detonate. 1 - Normally stable. Unstable at high temperature and pressure. Reacts with water. 0 - Normally stable. Not reactive with water. Key to Hazard (Special) Comments C - may be carcinogenic upon chronic exposure Cor ­ corrosive Exp - risk of explosion Oxy ­ oxidizing agent SC ­ suspected carcinogen T ­ toxic W­ water reactive Pol ­ polymerizes under normal conditions

Our School Safety Policy Our school is committed to provide, maintain, and improve safe working conditions in its laboratories and classrooms. In all instances RHHS will strive to eliminate at the source, dangers to the health, safety and physical well-being of students and teachers. It is expected that each student and teacher act responsibly in matters of safety and health that promotes a safe working environment.

Who Is responsible for Safety? 4 General – All students are responsible for a safe working environment – Teachers are responsible for providing: Safe working conditions Safe equipment Training

Students 4 Students are responsible for reviewing all pertinent safety programs 4 Complying with all safe work practices, rules and regulations 4 Recognizing hazards in the classroom 4 Reporting unsafe conditions to their teacher immediately

Safe Work Practices 4 Maintain a clean, uncluttered work area 4 Know the location of the nearest emergency exit and safety equipment (shower, eye wash, fire extinguisher) 4 Report all accidents your teacher

Good Laboratory Practices 4 No food or beverages in the labs 4 Required PPE must be worn while in the lab 4 Aisles & exits are free from obstruction 4 Lab benches must be cleaned, disinfected or decontaminated after work is completed

Good Laboratory Practices (continued) 4 Do not use hoods for storage 4 Work surface is protected from contamination 4 Heavy objects are confined to lower shelves 4 Glassware is free from cracks, breaks or chips 4 Broken glass containers are available & in use

Personal Protective Equipment 4 PPE must be worn when in the laboratory – Eye protection – Protective Clothing – Gloves When using chemicals or heat – Shoes No open-toed shoes allowed in laboratories

Hazard Communication 4 Primary & secondary containers are labeled with identity of material, expiration date & hazard warning 4 Signs on storage areas are consistent with hazards within (I.e. biohazard, flammable) 4 MSDS are available online

Chemical Storage 4 Incompatible materials must be segregated 4 Corrosives & flammables must be stored below eye level 4 Unused & outdated materials must be disposed of properly 4 Safety carriers must be used to transport all chemicals 4 Lab carts must have side rails

Waste Disposal 4 Dispose of liquid waste as instructed by teacher 4 Separate waste streams by type (biological, chemical), if necessary 4 Use approved containers for each waste stream 4 Label all containers with approved labels 4 Do not allow waste to accumulate on floors, in corners or under shelves

Safety Equipment 4 Know the location of safety equipment – Safety showers, eye wash stations & fire extinguishers 4 Make sure safety equipment & exits are not blocked 4 Spill team list and emergency numbers must be posted in labs next to phone

Emergency Evacuation 4 Know your exit route 4 Know the location of fire alarm pull-stations 4 Notify your teacher of any unsafe conditions

Safety Symbols

Safety Features of the Room 4 Draw a map of the room listing the following safety features: –Fire extinguishers (2) –Fire blankets (2) –Vent hood –Shower –Eyewash –Exits –Glass disposal container –Goggle Case
