11 WHY? Private Agencies/Businesses/Industry are held accountable for providing a safe working environment for their employees. Private Agencies/Businesses/Industry are held accountable for providing a safe working environment for their employees. 1.(Law suits cut into profits.) 2.Company is less productive when employees are lost or disabled. 3.Keeping experienced employees safe is more productive and profitable than constantly training replacements. 1.(Law suits cut into profits.) 2.Company is less productive when employees are lost or disabled. 3.Keeping experienced employees safe is more productive and profitable than constantly training replacements.

12 WHY? Manufacturers of tools and machines want to avoid lawsuits or recalls from defective products. Thats bad P.R. and will hurt sales. They also want you to come back and buy their products again. Manufacturers of tools and machines want to avoid lawsuits or recalls from defective products. Thats bad P.R. and will hurt sales.

15 Where Do Most Accidents Happen?

16 At Home We Think Were Safe and Drop Our Guard …and that false sense of security can lead to an Accident!

17 Recognizing Hazards

18 What is a Hazard? A hazard is a dangerous situation that could cause an accident. A hazard is a dangerous situation that could cause an accident.

19 Three Types of Hazards Immediate Hazard – A situation that is visible and presents an immediate danger. Immediate Hazard – A situation that is visible and presents an immediate danger. Potential Hazard – A situation that is visible but could become dangerous if combined with other situations or events. Potential Hazard – A situation that is visible but could become dangerous if combined with other situations or events. Hidden Hazard – An existing dangerous situation that is hidden from obvious view. Hidden Hazard – An existing dangerous situation that is hidden from obvious view.

20 Recognizing Hazards

21 Immediate Hazards

22 Potential Hazard

23 Hidden Hazard

24 Accident Prevention

25 Accidents can be prevented by… Identifying and correcting hazardous situations or conditions

26 Accidents can be prevented by… Keeping tools, machines and the work environment in the best possible condition

27 Accidents can be prevented by… Follow ALL Safety Rules Follow ALL Safety Rules Stay Alert Stay Alert Dont Take Chances Dont Take Chances IF IN DOUBT….ASK! IF IN DOUBT….ASK!

28 Overconfidence is Hazardous

29 Know your limitations. Get help when necessary.

30 School Lab Safety The only law affecting work in school labs is: The only law affecting work in school labs is: Georgia Code This law mandates the wearing of safety goggles by every student, teacher, and visitor participating in or observing chemical, physical, or combined chemical physical activities involving caustic or explosive materials, hot liquids or solids, injurious radiation or other hazards.

31 Protective Safety Devices

32 Optional Safety Devices Protective equipment that is available but the individual must choose to use. It does not work automatically. Protective equipment that is available but the individual must choose to use. It does not work automatically.

33 Eye Protection Safety Glasses Safety Glasses Eye Glass Side Shields Eye Glass Side Shields Goggles Goggles Full Face Shields Full Face Shields ALWAYS WEAR EYE PROTECTION WHEN WORKING IN THE LABORATORY!

34 Safety Glasses are stored in sterilizing cabinet

35 Optional Safety Devices Earphones protect against permanent hearing loss. Earphones protect against permanent hearing loss.

36 Non-Optional Safety Devices Protective equipment that is operating whether or not we decide to use them. Protective equipment that is operating whether or not we decide to use them.

37 CAUSES OF ACCIDENTS 80% of accidents are caused by human error. 80% of accidents are caused by human error. 20% of accidents are caused by unsafe conditions in the surroundings. 20% of accidents are caused by unsafe conditions in the surroundings.

38 Accident Statistics (Dont Be One)

39 What Body Parts Are At Risk

40 What Causes Most Accidents?

41 Accidents Take Their Toll Businesses spend $170 BILLION a year on costs associated with occupational injuries and illnesses – expenditures that come straight out of company profits. In addition Lost productivity from injuries and illnesses costs companies $60 BILLION each year. – O.S.H.A Businesses spend $170 BILLION a year on costs associated with occupational injuries and illnesses – expenditures that come straight out of company profits. In addition Lost productivity from injuries and illnesses costs companies $60 BILLION each year. – O.S.H.A Auto/Home owners insurance companies rates are higher in some places These factors determine the rates you pay: Where you live (apartments vs home) or drive the most, your sex, age group, your accident record etc. Auto/Home owners insurance companies rates are higher in some places These factors determine the rates you pay: Where you live (apartments vs home) or drive the most, your sex, age group, your accident record etc. The higher the risk that theyll have to pay, the higher your rates will be. The higher the risk that theyll have to pay, the higher your rates will be.

43 Fire Safety

44 Three Elements of a Fire

45 Classifications of Common Fires

46 Extinguishers are placed in easy-to- see & reach positions. Extinguishers receive regular inspections

47 Our Fire Extinguishers

48 IF THE FIRE CANT BE PUT OUT IN 15 SECONDS… Smoke kills more people than the fire itself.

49 NEVER USE WATER TO EXTINGUISH: Flame floats on water / Water conducts Electricity Both could cause serious injury or death.

50 Electrical Safety

51 Safety Around Electricity

52 Never Overload Circuits Wires could get hot enough to melt the insulation and cause a short circuit inside the wall.

53 What is a Short Circuit? Electrons are forced to move through the device when the circuit is working properly But Electrons will ALWAYS look for the shortest path back to where they came from…even if that means jumping (arcing) between two conductors which could electrocute or start fires.

54 Safety Around Electricity Capacitors inside the back of your TV store over 10,000 volts and can electrocute you EVEN WHEN ITS UNPLUGGED!!

DO NOT OPEN. DO NOT CLOSE. DO NOT ENERGIZE. DO NOT OPERATE

66 An unplanned event that may or may not result in an injury An unplanned event that may or may not result in an injury What is an Accident?

67 Clean Up ALWAYS CLEAN UP THE LABORATORY BEFORE YOU LEAVE!!!!

68 Whether at work or play one goal to say dont let safety be a stranger to thee. From hazards you cant tame you may not look the same.
