3 Can This Be You?

4 Why do we do this type of training? Injuries Death 89% of fatalities occurred with jobs authorized by supervisors. 80% of fatalities happened in locations that had been previously entered by the same person who later died. In 40% of fatal atmospheric accidents, the hazard was not present at the time of initial entry. accidents.

5 More Whys? 35% of those who died were supervisors. Only 7% of locations had warning signs indicating that they were confined spaces. 65 percent of confined space fatalities are due to atmospheric hazards. The remaining 35% are due to factors such as electrical shock or electrocution, being caught in or crushed by machinery, engulfment, falls inside the confined space, and ingress or egress

7 ASK YOURSELF… What is a confined space? What is difference between permitted and non-permitted confined spaces? List 3 examples of permitted confined spaces. When do I need PPE? When should I test the atmosphere? What is the safe oxygen level?

8 CLASS OBJECTIVES Help you understand the criteria of a confined space Motivate you to evaluate your workplace and written programs Implement changes where necessary

9

10 CLASS GOAL Prevent personal injuries/fatalities relating to a confined space entry

11 Class Will ADDRESS… Definitions of terms, with examples The basic entry procedure The components of a written program Specifics of a Good Program

12

13 1. CONFINED SPACE: Is large enough to enter into and work Has a limited means of entry/exit Is NOT designed for continuous periods of occupancy

14 CLASSES OF CONFINED SPACE Class A – IDLH atmosphere. May contain oxygen deficiency, explosive or flammable atmospheres, and /or concentrations of toxic substances.

15 CLASSES OF CONFINED SPACES cont’d Class B – space has potential for causing injury if proper safety steps are not followed

16 CLASSES OF CONFINED SPACES Class C – space has potential hazards, but would not require any special modification of the work procedures.

17 TYPES OF CONFINED SPACE… Non-Permitted … does NOT contain physical, chemical or atmospheric hazards capable of causing death or serious physical harm Permitted … DOES contain physical, chemical or atmospheric hazards capable of causing death or serious physical harm

18 NOTE: The classification of ANY confined space SHALL be determined ONLY BY Trained AND Authorized persons

19

20 2. ENGULFMENT A liquid or a “flowable” solid like sand or grain that can surround and bury, smother, strangle, or crush a person.

21 EGULFMENT cont’d Trenches deeper than 4ft Engulfment hazard: cave-in Preventive measure: shoring & evacuation route

22 3. IDLH Continued Immediately Dangerous to Life and Health Poses an immediate or delayed threat to life, OR… Causes irreversible adverse health effects, OR… Interferes with ability to escape unaided from a permit space

23 3. IDLH, cont’d May be used to determine need for PPE MSDS’s List of IDLH values If conditions meet or exceed IDLH values, implement IDLH Level PPE

24 4. QUALIFIED PERSON Designated by the employer in writing, as CAPABLE (by education, training, or both) of: Anticipating, recognizing, and evaluating employee exposure to hazardous substances or other unsafe conditions in a confined space; AND of Specifying necessary control and/or protective action to ensure employee safety

25 5. ATTENDANT An observant, competent/experienced person stationed outside of a confined space to assist the entrant

26 6. AUTHORIZED ENTRANT A worker authorized to enter a confined space

27 7. ENTRY SUPERVISOR The employee responsible for overseeing the Confined Space entry operations; permit signing; and safety compliance

28

29 GENERAL CS ENTRY PROCEDURE 1.Conduct an assessment 2. Post signage; Barricade 3.Write the Permit 4.Perform pre-entry tests 5.Follow all other safety procedures PPE LO/TO Ventilation

30 GENERAL CS ENTRY PROCEDURE, cont’d 6. Pre-entry briefing 7. Perform entry & work 8. Perform continuous atmospheric tests 9. Exit the confined space 10. Debrief employees/contractors 11. Verify completion

31

32 ASSESSMENTS MUST INCLUDE: 1. Pre-entry testing and monitoring of/for: Atmospheric conditions Potential hazards in and around the area

33 POTENTIAL HAZARDS Deficient or enriched oxygen Safe level: 19.5% - 23.5% Combustible, flammable, and explosive atmospheres Toxic gases and vapors Corrosive chemicals or biological agents

34 POTENTIAL HAZARDS cont’d Physical hazards– Falling,tripping,moving parts,engulfment,heat extremes,etc… Electrical hazards— Shock hazard, static electricity, sparks, etc… Rodents,snakes, and insects

35 ASSESSMENTS MUST ALSO INCLUDE: 2.Written procedures to remove or control hazards including ventilation, LOTO, PPE and communication 3.Written emergency response

36

37 POSTED SIGNAGE MUST be in the immediate area MUST identify the Confined Space Restricts unauthorized personnel E.G.: “DANGER—PERMIT REQUIRED CONFINED SPACE, DO NOT ENTER”

38 BARRICADES MUST prevent unwanted access to the work area MUST ensure clear workspace for attendant and emergency rescue (if needed)

39

40 PERMITS Are written authorization and approval specifying the location and type of work Certify that all existing hazards have been assessed Ensure the safety of each worker Specify the date & length of time it applies

41 Confined Space Permit

42 NOTE: PERMITS ARE ALWAYS POSTED IN THE WORKPLACE DURING ENTRY

43

44 TESTING STANDARDS Duration—Recommend continuous Sample priority—Oxygen; Flammable/combustible chemicals; Toxic chemicals

45 TESTING METHODS Sample in layers Every four feet in direction of travel Different chemicals stratify Do not get equipment wet!!

46 CHEMICAL STRATIFICATION *Chemicals will stratify according to their vapor density * Strata changes with environmental conditions (ex. Temperature and pressure)

47 REMEMBER TO DOCUMENT ALL ATMOSPHERIC TESTING RESULTS!!

48

49 OTHER SAFETY PRECAUTIONS PPE Lockout/Tag out Verify emergency response Remove sources of hazardous materials outside of confined space Ventilation

50 VENTILATION Exhaust Negative pressure Local - for specific sources General - for non-specific sources Purging Positive pressure Using inert gases in flammable/combustible environment Causes need for additional PPE

51

52 PRE-ENTRY BRIEFING Conduct meeting Include all affected persons Document topics discussed at the briefing.

53

54 Entry documentation Each entrant should sign an entry log Posted in immediate area

55 Follow work procedures and safety rules for job task!!!

56

57 CONTINUOUS MONITORING REMEMBER the mentioned sampling methods!

58

59 EXITING THE CONFINED SPACE When work is complete, when replacement arrives, or if an alarm sounds In the event of an emergency, utilize emergency rescue Remember to update the entry log!!

60 ON-SITE RESCUE Employer determined if on/off-site rescue will be used On-site, usually comprised of in-house personnel— Motivated team Extensive training Practical exercises (min. once/12 months) Regular reinforcement of training

61 OFF-SITE RESCUE Assessment necessary Determine the practicality of off-site rescue If used: Close proximity Extensive pre-coordination Must understand the hazards to be faced Must have access to all spaces for pre- planning

62

63 DEBRIEFING Discuss the success of the work Identify concerns that occurred Verify completion of all documentation Document meeting, if possible

64

65 VERIFY COMPLETION The entry supervisor should remain for at least 30 minutes after the entry to ensure the security of the site and that no hazards remain (ex. Fires)

66

67 PROGRAM ELEMENTS: Identification and location of ALL recognized confined spaces Hazard evaluation procedures Warning procedures Ex: Signs at entrance

68 MORE ELEMENTS… Written procedures for pre-entry and entry Written procedures for permitting

69 MORE ELEMENTS… Assignment of responsibilities Entrant Attendant Entry supervisor

80 SUPERVISOR cont’d Perform non-entry rescue in accordance with policy Perform no duties that interfere with supervisor duties

81 Hopefully we never need……

82 Emergency Response Attendant alerts the rescue services Close off the area Get authorized entrants out of the space Perform first aid if needed. Chest or body harnesses are worn by authorized entrant to allow for safe rescue.

83

84 EXAMPLES…

85

86 TRAINING REQUIREMENTS New employees At time of employment, if affected…or… When delegated affected responsibility Existing employees Refresher training Rescue drills at least annually

87 TRAINING CONTENT All aspects of the written program Emergency procedures Document all training activities

88 RECORD KEEPING REQUIREMENTS Written program Training records Atmospheric testing records Permitted and non-permitted entries into confined spaces

89

90 Let’s review… What is a confined space? What is difference between permitted and non-permitted confined spaces? List 3 examples of permitted confined spaces. When do I need PPE? When should I test the atmosphere?

91 Let’s review… What is the safe oxygen level? Where should the permit be maintained during entry? When should an entrant exit the confined space?

92 Regulations February 1994 CAL-OSHA enacted their final rule for confined space relations Title 8, California Code of Regulations (CCR), General Industry Safety Orders (GISO), Sections 5156, 5157, 5158 Outside California FED-OSHA has a near identical document American National Science Institute (A.N.S.I.) and National Institute for Occupational Safety and health (N.I.O.S.H.) guidelines are also used.*

93 An Preventable Accident

94 Fatality Statistics Studies reveal that every year approximately 67 preventable deaths occur in confined spaces As many as 60% of the deaths to occur would be rescuers* Research reveals interesting facts regarding the causes of deaths in confined spaces 65% hazardous atmospheres * 13% engulfment 7% struck by falling objects 6% heat stress/exposure 4% others

95 Not all will be labeled!

96 Some will be!

97 Injury and Illness Prevention Safety responsibility Compliance/recognition Employee-employer communication Workplace inspections/evaluation Correction of hazards Injury/illness investigation Training Recordkeeping

98 Definitions of Confined Space Confined spaces are subdivided into two groups 1. Confined Space a) Is large enough and so configured that an employee can bodily enter and perform assigned work; and b) Has limited or restricted means for entry or exit; and c) Is not designed for continuous employee occupancy

99 A permit required space must meet the definition of a confined space plus one of the following:* Contains or has the potential to contain a hazardous atmosphere Contains a material that has the potential for engulfing an entrant Has an internal configuration such that an entrant could be trapped or asphyxiated by inwardly converging walls, or a floor which slopes and tapers to a smaller cross section or Contains any other recognized serious safety or health hazard Permit Required Confined Space

100 Typical Permit Required Confined Spaces Storage tanks/bins Pump wet wells Degreasers Digesters Sewers Person holes Tunnels Underground vaults Boilers Hoppers, pump stations, scale pits, crawl spaces Silos Vaults Vessels Grain elevators Mixers Open topped water tanks Water towers Enclosures with bottom access Rail car tanks

113 Dangers of Confined Spaces Oxygen deficiency By-products of previously stored materials Storage tanks retain residue Product is absorbed into tank walls Accidental leaks or spills Leaks of substances give off vapors or cause reactions Slip, trip or fall hazard Chemical Reactions Accidental mixing of chemicals Drying paint Multiple use tanks

114

115 Dangers of Confined Spaces Oxidation Rusting of metals Rotting or decomposing organic materials Mechanical Operations Welding Painting Cleaning Scraping or sandblasting Missing/stirring operations Recharging of batteries Inerting Activities Carbon dioxide (CO 2 ) Helium (HE) Nitrogen (N 2 )

116 Types of Confined Space Hazards Confined space hazards are basically grouped into six groups Atmospheric hazards Physical hazards Engulfment hazards Corrosive hazards Biological hazards Other hazards

117 Effects of Hazardous Atmospheres Suffocation* 65% of fatalities occurring in confined spaces are a result of hazardous atmospheres * Poisoning * Explosion/Fire *

118 Hazardous Atmosphere An atmosphere which exposes employees to a risk or death, incapacitation, injury or acute illness from one or more of the following causes O2 level below 19.5% or above 23.5% Flammable gas or vapor in excess of 10% of L.E.L. Airborne combustible dust at a concentration that obscures vision at 5 feet or less Any immediately dangerous to life or health (IDLH) atmosphere

119 Target Gases and Effects Oxygen* Must be between 19.5% and 23.5% by volume for atmosphere to be considered safe* Above 23.5% by volume the environment becomes unstable and prone to flash fires or explosion Below 16% physical effects will become apparent Methane Colorless Odorless Non-toxic Asphyxiate (displaces O2) Lighter than air* Explosive range (5% to 15%)

120 Target Gases and Effects Carbon Monoxide* Colorless Odorless Toxic Asphyxiant (displaces O 2 ) Vapor density = to air Explosive range (12.5% to 74.2%)

121 Target Gases and Effects Hydrogen Sulfide* Colorless Smell like rotten eggs Toxic Vapor density is 1.89 Explosive range (4% to 44%) Common in sewage facilities Diminishes your sensitivity to smell Sulfur dioxide Pungent Irritating gas 1-10 ppm exposure causes respiratory and pulse rate increase and decrease in depth of respiration Vapor density is 2.26 Non-flammable

122 Target Gases and Effects Carbon dioxide Colorless Odorless Non-combustible gas Toxic Exposure symptoms Headache Dizziness Restlessness Vapor density is 1.53

123 Target Gases and Effects Ammonia Colorless unless High Levels Odor Potentially combustible gas Toxic Exposure symptoms Burning Breathing Impact Vapor density is 0.769 g/L

124 Atmospheric Monitors Types of air monitors/alarms Single gas monitors a) Will monitor only one preset gas Multiple gas monitors a) Will monitor multiple preset gases 1) Monitors that sense four (4) gases at once are commonly used in confined space operations referred to as four (4) in one (1) monitors

125 Monitoring Operations Monitoring should be done in the following order every time Oxygen content (first)* Flammable gases/vapors (second)* Potential toxic contaminants (third)* Testing should be done prior to lifting person hole covers To get the most accurate reading To eliminate potential explosions Testing should be done at all levels of the confined space Stratification of gases may occur due to vapor density of gases vary Testing must continue periodically Results of monitoring must be logged An entry permit as well as data log of monitor if equipped

126 Physical Hazards Grinding equipment* Agitators Mulching equipment* Drive shafts Gears and other moving equipment Steam or steam fittings Electrocution Falling objects*

127 Engulfment Hazards Material involved in engulfment incidents* Grains Sand Gravel Cement Clay Sawdust Liquids Causes of engulfment incidents Walking on unstable material that has void spaces below Bridging* Improper or lack of use of safety/retrieval lines Overhead flow of particulate matter or liquids activated inadvertently

128 Case Study On June 6, 1998, a 56 year-old worker died when he was engulfed by sand in a hopper at a concrete pipe manufacturing company. His job as a "material man" was to direct the flow of sand and gravel from storage bins to hoppers housed in a shed on top of the plant. Since there was only one conveyor that moved sand and gravel from storage bins to the shed, the material man had to enter the shed and manually operate a lever that controlled the flow of sand or gravel into the correct hopper. He entered the 17 foot deep hopper filled with sand, perhaps by falling, was engulfed, and suffocated.

129 Case Study A 23-year-old mill operator and a 20-year-old maintenance technician were killed when they were engulfed in corn in a 6,000 bushel cone bottom gravity feed bin at a feedlot. The two individuals had been "knocking down" soy bean meal in a gravity feed bin next to the corn bin prior to the incident. For some reason, after their work in the soy bean meal bin they went to the corn bin and both individuals became engulfed in cracked corn. Both of these bins were active, flowing soy bean meal and cracked corn into a "clam" approximately once every five to ten minutes. The "clam" was then emptied into feed trucks. When the corn flowed from the bin, this pulled the victims under the corn. When others at the feedlot realized the two were trapped in the corn, they cut openings in the bottom of the bin to release the corn and rescue the victims. Both individuals died from suffocation.

130 Target Industries Physical and engulfment hazards Industry with mechanized assembly equipment Spaces with electrical, hydraulic or pneumatic equipment supplied to it, or within it Grain or particulate matter production or processing Industries that have spaces with top load applications Industries that have spaces with bottom dump applications

131 Lock-Out/Tag-Out Procedures Procedures performed to isolate any potential energy source to the space Electricity Hydraulic Steam Drive mechanisms Pneumatic Gravity flow of product Must be Performed by an authorized employee* Printed tags and locks are used to warn other employees of isolated energy source

132 Lock-Out/Tag-Out Procedures Examples of lock-out/tag-out* Electrical switches locked-out Hydraulic lines blocked and bled Steam line blind flanged Drive mechanisms disconnected Drive belts removed Liquid valves locked-out Overhead dumps locked-out

133 Lock Out Tag Out

134 Entry Permits A form or tactical worksheet required by CAL-OSHA that must be completed for confined space entries Components of an entry permit Location Purpose of entry Date of entry and authorized duration List of authorized entrants List of attendants Entry supervisor signature List of necessary tools and equipment List of special hazards Results of initial and periodic atmosphere tests Measures to isolate the space and control hazards prior to entry Lock-put/tag-out Listing of rescue and emergency services Communications procedures Additional

135 Lock Out Tag Out

136 Entry Permits Prior to entry to entry supervisor must Approve the permit * Upon completion of entry Permit must be signed and cancelled by the entry supervisor * Permit must be filed and retained at least one (1) year *

137 OSHA Exemptions to Permit Regulations Selected construction operations Defined by section 1502 Selected agriculture operations Defined by Section 3437 Marine terminal operations Defined by Section 3460 Shipyard operations Regulated by Section 8437 Telecommunications people holes and vaults Regulated by Section 8616 Grain handling facilities Defined by Section 5158 Electric utility operations within underground vaults

138 OSHA Exemptions to Permit Regulations Exemptions based on employer proof of atmospheric hazard only Must not contain any other hazards except atmospheric condition only Hazard can be eliminated by ventilation alone When exemptions are granted components of the normal entry program may or may not be present Entry permit may not be provided Attendant my not be present Entrant lowering and retrieval equipment may not be present Exemptions are only valid when entry is for the prescribed purpose To evacuate an injured worker out of an exempted space would nullify the exemption, and Sections 5156, 5157 and 5158 would prevail.
