Assuming a corridor with a door entering it from one side, then the door being opened into the corridor would be considered a hazard in the event of an H&S risk assessment. To reduce the risk would involve taking action and, were I doing the assessment, my recommendation would be to reverse the opening of the door so it opens inwards rather than outwards into the corridor. If this is not feasible for whatever reason, them the next best would be to fit a viewing panel or a complete glass door so anyone coming out through the door would be able to see anyone walking along the corridor. Unless you can prove that the company have not given consideration to the possibility of someone being injured by the door being opened into them, then you cannot claim against the company. However, you haven't been injured so I doubt you would be able to claim.
