4. Safety Management 4

5. Control Measures (in order of preference) Use a less risky material Use a safer form of that material (e.g. solution instead of powder) 5

6. Control Measures (in order of preference) Totally enclose the process ( e.g a glove-box) Partially enclose the process (e.g. with a fume cupboard) Ensure good general ventilation 6

7. Control Measures (in order of preference) Safe systems of work Reduce exposure times, increase distance, reduce volumes Personal protective equipment 7

8. 8 Personal Protective Equipment (PPE) is any safety equipment workers wear to prevent injury in the workplace when engineering and administrative controls fail to eliminate the hazard.

9. 9 Why head protection is important… face Hair Teeth

10. Common Types of PPE Head Eyes Face Hands Feet Body Hearing Respiratory

11. 11 PPE controls : Requires worker to wear something Examples

12. Head PPE Needed when employees are exposed to hazards that have potential to cause a head injury. Examples of hazards: Flying objects. Falling objects or materials. Working near exposed energized electrical equipment. Working around or on scaffolds. Working at construction sites. Working around overhead tools or machinery.

13. 13 Scaffolds

14. 14 Head protection: Frequent causes of head injuries Falling objects from above striking on the head; Bump head against fixed objects, such as exposed pipes or beams; or Accidental head contact with electrical hazards.

16. Source: OSHA CLASS E (Electrical) Designed for electrical/utility work Protect against falling objects, impact E lectrical protection against high-voltage (proof-tested to 20,000 volts) Types of PPE

17. Source: OSHA CLASS C (Conductive) Designed for comfort; offers limited protection Protects heads that may bump against fixed objects Does not protect against falling objects or electrical hazards Types of PPE

18. Selecting eye and face protection – elements to consider: Ability to protect against workplace hazards Should fit properly Should provide unrestricted vision and movement Durable and cleanable Allow unrestricted functioning of other PPE Types of PPE

19. Promoting Safety Awareness The most effective way to eliminate accidents? Develop and maintain safety and health awareness among all students and staff Recognize and promote safe work practices and reinforce positive attitudes towards safety General and specific safety rules

21. Protect Yourself Eye Safety Wear safety goggles when working with chemicals, flames, or heating devices. or if possibility of scattered pieces. If you wear contact lenses let your teacher know 21

22. Safety First You will be doing many lab activities , which require the use of hazardous chemicals and expensive lab equipment. Safety in the lab is the #1 priority . To ensure a safe science classroom, a list of rules has been developed. These rules must be followed at all times. A signed lab safety contract is required to participate in labs. 22

23. What are the general hazards in a lab? Fire Breakage of glassware Sharps Pressure equipment & gas cylinders Extremes of heat & cold Chemical hazards Radiation And many more! 23 Elimination/substitution or Engineering controls Eliminate toxic material or substitute a less toxic material Enclose or confine operation General or local exhaust ventilation
