Are you a competent confined space entry planner?
Will your team escape safely? Will a casualty run out of air during the rescue?
Constant Flow Emergency Escape Breathing Apparatus (EEBA) are commonly specified for confined spaces, like the CF15 illustrated. A simple, robust system, it’s common on training courses, hire fleets and confined space jobs.
Advantages: Simple to use, no quantitative face fit required, low skills maintenance, affordable, readily available on hire fleets.
However, as the competent person planning the job, you need to consider if this is a safe system of work.
Will your entrants breath above the supply rate? If the wearer is working hard, climbing a long ladder or anxious they can create negative pressure inside the hood and contaminate themselves during the escape. Have you risk assessed the work rate and confidence (experience) of the entry team to escape at low breathing rates? Is the route out a short walk or more demanding?
Are the EEBAs fully charged? Often you get a pressure drop, especially on cold days with hire sets on site for multiple days. A CF15 dropped from 200 to180 bar means your CF15 will only last 13 minutes!
Have you factored in “waiting time” for multiple entrants at a ladder or winch? How long will it take to get all your team out . Are you dispatching rescuers into the confined space via the same route?
Have you considered that your entrants will probably be escaping in a state of anxiety, their helmets on (head injury risk) and may have lost their lighting too. Confusion, noise, restricted visibility all add to the stress of the escape. Are your team practiced or was their last wear, in a training centre two years ago? Are they competent? Its your decision…
How about the casualty left behind in the confined space? Even if wearing an EEBA. Will they survive long enough for the rescue team to mobilize, access the confined space, pass the exiting entrants, reach the casualty… package and extract back and out of the system? Have you assessed if this is viable and likely, if not you haven’t done your job as the competent planner.
Safety starts with planning....
