Study Notes
2 In / 2 Out Procedure
- The purpose of the 2 in / 2 out procedure is to meet the OSHA standard (29 CFR 1910.134(g)(4)) and ensure the safety of firefighters during interior structural fires.
- The objective is to have fully equipped firefighters in position to react in case of a Mayday situation.
OSHA Standard
- OSHA states that fire fighters begin the interior attack on an interior structural fire, the atmosphere is assumed to be Immediately Dangerous to Life or Health (IDLH) and the 2 in / 2 out procedure applies.
Exceptions to the 2 in / 2 out Requirement
- Reported or suspected life hazard where immediate action could prevent the loss of life.
- Fire is in an incipient stage (defined as a fire which can be controlled or extinguished by portable fire extinguishers, Class II standpipe or small hose systems without the need for protective clothing or breathing apparatus).
Operational 2 in / 2 out
- A temporary two-person tactical reserve assigned at the outset of an incident to allow teams to enter an IDLH, or potential IDLH atmosphere.
- One primary member of the 2 in / 2 out pair must be solely dedicated to tracking interior personnel.
- The second member of the 2 in / 2 out team may be engaged in other activities within the hazard zone.
Implementation of 2 in / 2 out for a Four-Person Crew
- The plug person assumes the primary 2 in / 2 out position and the engineer assumes the secondary 2 in / 2 out position.
- Rescue efforts should be initiated as a team (2 members) and well communicated prior to action.
- Mayday response should be managed with the Risk Management Plan by the incident commander and acted upon based on the capabilities of the 2 in / 2 out team.
