Emergency arrangements are a specific requirement of Confined Spaces Regulations 1997 - Regulation 5 - Emergency arrangements. In accordance with these regulations and ACoP paragraph 147, you cannot reply on the emergency services.
Each confined space identified should have a rescue plan specific to that confined space and the task or activity being undertaken in it to be able to sustain any casualty at the scene and during the evacuation, to a place where the emergency services can take over.
There must be suitable arrangements for emergency rescue to be able to sustain any casualty at the scene and during the evacuation, to a place where the emergency services can take over.
Self-rescue involves an entrant leaving the space under their own capacity, either because they have identified a hazard (e.g. gas monitor alarm indicating a potentially dangerous condition) or are feeling ill. Equipment may be provided to enable self-escape from the confined space in an emergency. Examples of these include constant rate descenders for escape in a fire or escape breathing apparatus where the oxygen level is suddenly depleted or increased concentration of another gas situation.
Escape equipment may only be appropriate for use in situations where there will be time to react to an anticipated emergency and the entrant is conscious and not incapacitated in any way. Due to nature of the confined space and potential risks, self-rescue alone may not be sufficient, assisted rescue will also need to be considered.
Assisted rescue could require one or more people dedicated to the rescue role and rescue could be either undertaken by non-entry (external) rescue e.g., entrant is permanently attached to a recovery line, or will involve additional people entering the confined space to perform the rescue.
Some confined spaces on the turbine could have reduced horizontal and vertical space and restricted manoeuvrability (basement/transition piece, yaw section, transformer room or between canopy and generator of a Direct Drive WTG) which may require evacuation of an injured person from this area to a location were first aid can be administered.
All personnel on site should be competent to respond to emergency situations. Training needs will vary according to any designated role. There are recognised occupational standards available for confined space rescue personnel.
