The London P&I Club has warned of the potential dangers faced by seafarers on entering enclosed onboard spaces, in the event that proper safety procedures are not followed. IMO recommends that a competent person should undertake a preliminary assessment of the risk that the atmosphere might be toxic, flammable or oxygen-deficient. And, writing in the latest issue of its StopLoss Bulletin, the Club says, “The need for such measures has again been underlined by a recent case in which the responsible officer undertook a risk assessment prior to entry into a large chain locker, and concluded that there was no significant risk involving toxic or flammable vapours or gases.
