Title: Confined Space Entry


1
Confined Space Entry
  • Presented by the Office of Environmental Health
    and Safety

2
Safety Through Teamwork
  • Nothing is so important that it can not be done
    safely.

3
Training Outline
  • Introduction
  • OSHA Regulations
  • General Hazards
  • Permits
  • Atmospheric Testing
  • Safety Procedures
  • Training and Duties of the Confined Space Entry
    Team
  • Review and Quiz

4
Introduction
  • Confined space definition
  • Is large enough that an employee can enter and
    perform assigned work
  • Has limited or restricted means for entry or exit
  • Is not designed for continuous employee occupancy

5
Introduction
  • Examples of confined spaces
  • storage tanks
  • pits
  • silos
  • vats
  • tunnels
  • sewers
  • shafts
  • exhaust ducts

6
IntroductionRegulatory Requirements
  • OSHA- employee safety- permit confined spaces- 29
    CFR 1910.146
  • The employer must assess the workplace to
    determine if hazards are present that necessitate
    the use of PPE

7
Permit Space Hazards
  • Hazardous atmosphere (too little or too much
    oxygen, flammable or toxic air)
  • Engulfment
  • Danger from unexpected movement of machinery
  • Electrocution
  • Heat stress
  • Becoming wedged into a narrow space and
    suffocating

8
Reducing Risks of Hazards
  • Post signs to alert employees to the dangers of
    confined spaces
  • Use barriers to keep unauthorized employees out
    of permit spaces
  • Develop and use a written space entry program
  • Conduct air monitoring and other tests to
    identify and evaluate hazards in each permit
    space
  • Ventilate, eliminate, or control the spaces
    atmospheric hazards before entry into the space

9
Permits
  • Permit space
  • Purpose, date authorized length of entry
  • Authorized entrants and supervisor by name
  • Hazards of the identified space
  • Control and isolation methods
  • Acceptable entry conditions
  • Results of initial and periodic atmospheric
    testing
  • Rescue and emergency services to be summoned
  • Communication procedures
  • Equipment to be provided

11
Preparation of Permit Space
  • Notify all affected departments
  • Post signs and put up barriers to protect
    entrants from traffic and pedestrians
  • Blind or disconnect and cap all input lines so
    that no hazardous materials can enter the space
  • Empty space of any materials that may be
    hazardous
  • Verify breathing safety by air testing
  • Add emergency contact telephone numbers

12
Atmospheric Testing
  • Continuously test and monitor air in all areas
    before entry
  • Make sure that the oxygen content is between 19.5
    and 23.5 percent
  • List any toxic materials that could be present
    and their permissible exposure limits
  • Evaluate heat stress potential
  • Control any hazards present before entry
  • Evacuate the space and cancel the permit if air
    becomes hazardous

13
Monitors
14
Monitors
  • Simultaneously monitors up to four atmospheric
    hazards
  • carbon monoxide
  • flammables
  • hydrogen sulfide
  • variable oxygen levels

15
Safety Procedures
  • Authorized entrants can enter a permit space only
    after its been tested and found safe for entry
  • The assigned entrant has to know what equipment
    to use- and how to use it
  • Once prepared, you want to get in and do the
    assigned task as quickly and efficiently as
    possible
  • Alert the attendant immediately if you recognize
    a sign or symptom of exposure to a dangerous
    situation

16
Training and Duties of the Confined Space Entry
Team
  • Duties of the Entry Supervisor
  • Verifies that the permit is filled out completely
    and all safety steps listed are taken, then signs
    the form
  • Checks conditions to ensure they stay safe
    throughout the work
  • Sees that any unauthorized people are removed
  • When work is complete, cancels the permit and
    concludes the operation

17
Training and Duties of the Confined Space Entry
Team
  • Duties of the Attendant
  • Maintains an accurate count of whos in the
    space, monitors activities inside and outside of
    the space, and stays in touch with the entrants
  • Keeps unauthorized persons out of and away from
    an occupied permit space
  • Orders evacuation of the permit space, entrants
    show signs of behavioral effects of hazard
    exposure, or an outside situation that could
    endanger the workers in the space
  • Summons rescue and emergency services when needed

18
Training and Duties of the Confined Space Entry
Team
  • Duties of the Entrant
  • Knows the hazards of the space and signs of
    exposure
  • Follows personal protective equipment training
    carefully
  • Keeps in contact with the attendant, leaves space
    at once if instructed to do so
  • Is always ready to evacuate quickly
  • Leaves the space and tells the attendant if there
    is danger

19
Training and Duties of the Confined Space Entry
Team
  • Emergency and Rescue Procedures
  • Self rescue
  • An entrant evacuates the space with no help
  • Non-entry rescue
  • Only workers trained in rescue can enter the
    space for the purpose of rescue and only when
    there is another attendant present

20
