Directions: Read the passage below to answer questions 34 to 43.

Confined Spaces

Rescue operations carried out by firefighters inside locations that are below ground and restricted from natural ventilation are known as confined space incidents. Examples of confined spaces are water tunnels, utility trenches, ship holds, and storage tanks. The safety of the rescue workers is the most important factor in these situations. Recognizing the inherent hazards of the confined space prior to entry is paramount to a safe and successful operation.

Atmospheric condition hazards that must be addressed by rescue workers include oxygen deficiency, combustible and flammable gas vapors, and toxic gases. Physical hazards may also be present inside the confined space. Limited access and egress, unstable structural conditions, liquids in depth, and open gas lines or live electric lines are just a few of the physical hazards encountered.

No firefighter should enter a confined space location alone. The wearing of all personal protective equipment (PPE) and the use of positive pressure breathing apparatus (SCBA) is mandatory for firefighters working inside confined spaces. Long air supply hoses may be utilized and attached to the SCBA to allow firefighters to work for longer periods of time inside the space. Each firefighter entering the confined space must be attached to a lifeline (rope) and constantly monitored by a safety officer. The safety officer must keep a log of all members inside the confined space, how long each member has been operating, and how much oxygen each rescuer has remaining to ensure a safe return. A standby team must be assembled by the safety officer equal in number to the rescuers working inside the confined space. This reserve team must have the tools and equipment necessary to safely enter, medically treat, transport, and remove any and all rescue workers inside the confined space should the need arise.

A communications system must be established between the rescue workers and the safety officer. Portable radios may not be the method of choice if rescue workers are inside a combustible or flammable atmosphere for fear of an explosion as a result of radio transmissions. One way of communicating is via the OATH method. Each letter represents a single tug from the lifeline. One pull (O) on the rope by both exterior and interior members in reply stands for the verification that the members inside the confined space are OK and not in any danger. Two tugs (A) from each group represent the advancement of air supply line. Conversely, three pulls (T) from each end of the rope calls for the taking up of air supply line. Four tugs (H) is a distress signal and a call for help from the members inside the confined space with confirmation (four tugs) from members outside the confined space that help is on the way.

The establishment of a command post and staging area is also critical at confined space operations. A command post is required for the incident commander (ranking chief officer) to coordinate manpower and equipment resources. From the command post, the incident commander will also meet with other agency leaders who will be needed for assistance that is essential to a successful operation. The staging area should also be formed in an adequate space far enough away from the incident as not to interfere but close enough for resources to arrive at the command post in a timely fashion. A staging area chief officer should be designated in charge to ensure resources are recorded and properly managed both to and from the incident. Confined space operations are inherently dangerous to both trapped victims and firefighters. No firefighter should enter a confined space without these safety procedures being implemented. It is the responsibility of all supervisors to ensure that these rules are adhered to by all firefighters under their command. The special precautions listed in this article will not guarantee a successful operation but will enhance the safety of all firefighters.

34. Which of the following is NOT a true statement about the OATH method used to communicate with firefighters inside a confined space?

(A) One pull at each end verifies that firefighters inside the space are OK.

(B) Two pulls at each end represents the stretching of a hose line.

(C) Three pulls at each end calls for taking up the air supply line.

(D) Four pulls is a distress signal.
