Activity 12 Using an Air Lock to rescue a
Survivor - Level 2

• Arrangements
• Arrange to use a a refuge chamber as the
  barricaded areas. (If you do not have a refuge
  chamber, a bulkhead with a man door could be used
  as the barricade.) Otherwise, you will have to
  have a barricade built in preparation for this
  activity.
• Arrange for someone to play the role of the
  uninjured survivor.
• Set up a simple fresh air base a distance from
  the barricaded area.
• Have someone stay at the fresh air base to handle
  communications from the team.
• Also, have someone at the fresh air base serve as
  the communication line, or cable attendant.
• Prepare copies of a map of the barricaded area.

Activity 12 Using an Air Lock to rescue a
Survivor - Level 2

• Description
• Have the team or benchman prepare the apparatus.
  When ready, the team should report to you with
  their apparatus and equipment.
• Give the teams mapman a map showing the
  barricade and the route of travel to it.
• Tell the team that the area has been explored.
  The teams job therefore is to go in, put in a
  airlock and bring out any survivors found behind
  the barricade.
• The captain should then lead the team to the
  fresh air base, have the team members check their
  equipment and get under oxygen.
• When the team is ready, let them begin their
  assignment. You should accompany them to observe
  and evaluate their performance. The individuals
  staying at the fresh air base should stand by
  ready to perform their duties.
• Debrief the team when they return.

Activity 13 Determining Hazards and Procedures
in a Recovery Operation Level 1

• Purpose The team will practice assessing post
  disaster conditions to determine the hazards
  present and the procedures that should be
  followed in carrying out the recovery work.
• Type Classroom discussion.

18
Activity 13 Determining Hazards and Procedures
in a Recovery Operation

• Materials
• Level or section map showing post disaster
  conditions (use the one provided or make your
  own.)

19
Activity 13 Determining Hazards and Procedures
in a Recovery Operation

• Arrangements
• Give team a copy of a level or section map
  showing past disaster conditions and, if
  possible, project the map as an overhead
  transparency or as a PowerPoint projection.

20
Activity 13 Determining Hazards and Procedures
in a Recovery Operation

• Description
• Describe the recovery situation to the team. (You
  can use the sample provided below as a guide.)
  Also, give the team a map depicting the
  situation.
• Ask the team to discuss the hazards of the
  situation and what procedures they would follow
  in carrying out their assignment.

21
Activity 13 Determining Hazards and Procedures
in a Recovery Operation

• Sample Recovery Situation (Single level mine)
• Because efforts to fight the fire directly have
  failed, an area of a mine has been sealed. The
  plan is now to reopen the sealed area by means of
  progressive ventilation. Recent air samples
  indicated no traces of CO in the sealed area and
  a low oxygen level.

22
Activity 13 Determining Hazards and Procedures
in a Recovery Operation

• Sample Recovery Situation (Single level mine)
• Look now at the map. Another rescue team has
  already put up a air lock in No. 4 Entry. Your
  teams assignment is to go in, explore, and
  assess conditions. Be sure to check all entries
  and crosscuts and tie-in as you go. Do not
  advance any farther than two break throughs.

23
Activity 13 Determining Hazards and Procedures
in a Recovery Operation

• Sample Recovery Situation (Single level mine)
• What hazards might you encounter as you explore
  the area?
• How would you advance and what tests should you
  make as you advance?
• What conditions should you be reporting on?
• How many bulkheads are needed to reseal the
  unexplored area and where should the bulkheads be
  placed?

24
Activity 13 Determining Hazards and Procedures
in a Recovery Operation

• Answers to Sample Recovery Situation
• The hazards the team might encounter are
• Toxic or explosive gases
• Weakened ground conditions (because of the heat
  from the fire).
• Hot spots or smoldering material (These could
  flare up into fires or cause a gas ignition).

25
Activity 13 Determining Hazards and Procedures
in a Recovery Operation

• Answers to Sample Recovery Situation
• The team should tie-in all entries and crosscuts
  and take temperature readings, test the back and
  sides and test for gases as they advance. You may
  wish to have the team describe in exactly what
  order they would explore the entries and
  crosscuts.

26
Activity 13 Determining Hazards and Procedures
in a Recovery Operation

• Answers to Sample Recovery Situation
• The team should report on
• Gas conditions
• Ground conditions
• The condition of all ventilation controls
• The condition of any power lines, communication
  lines, or air or water lines in the area.
• Eight bulkheads are needed to reseal the
  unexplored area. See the maps below for placement
  of bulkheads

Activity 14 Mock Disaster Training Session
Level 2

• Purpose To provide mine rescue training not only
  for the teams but for other mine personnel who
  would be involved in the event of an actual mine
  rescue situation.

33
Activity 14 Mock Disaster Training Session
Level 2

• Description and Arrangements
• A mock disaster is a simulation of an actual mine
  rescue operation. It requires setting up a
  command center, establishing a fresh air base,
  and deploying teams on a rotation schedule.
• The idea is not new. A number of companies
  already use a mock disaster training session as
  part of their total emergency preparedness
  training.

34
Activity 14 Mock Disaster Training Session
Level 2

• Description and Arrangements
• The preparation necessary for putting on a mock
  disaster training session include
• Preparing areas for a command center and fresh
  air base (both with necessary communications)
• An underground area the team will be working in
  (placards can be used to indicate various
  conditions).
• You will need to have maps of the underground
  area.
• A briefing and team assignments
• A team rotation schedule
• An area set aside for teams to prepare and clean
  their apparatus.

35
Activity 14 Mock Disaster Training Session
Level 2

• Description and Arrangements
• The personnel needed to carry out the mock
  disaster include
• Mine rescue teams (at least three, although four
  is probably the optimum number for a single days
  training session)
• Appropriate safety and management people to man
  the command center and fresh air base
• Its also important to involve the other surface
  personnel who should be called in on a real
  rescue situation.
• For instance, you can have guards checking people
  as they come on property, a supply clerk, lamp
  man, mine electrician, mechanical foreman, and so
  on.

36
Activity 14 Mock Disaster Training Session
Level 2

• Description and Arrangements
• Additionally, you may want to invite MSHA and
  (where applicable) state officials to observe or
  participate in the mock disaster. And, youll
  need equipment and food for all people.
• Obviously, a mock disaster training session
  requires the participation of quite a few people,
  particularly. Management-level people. While it
  can be a significant outlay of money and time, a
  mock disaster training session can also be an
  extremely valuable training experience. For the
  teams, its realistic training session, and for
  the people in charge, its an opportunity to
  practice coordinating and directing rescue work.
