Some operatives were observed to be working with  a podium ladder behind the door that led to the North area tunnel of Level-0 of the site, without adequate signage and barrier to indicate the ongoing activity. There is a very  risk of collision with the door if suddenly opened by someone who's not aware of the ongoing chipping works behind the door. The activity was immediately discontinued and the supervisor and the safety officer in charge were informed about the SSOW.   ACTION: CMA advised TCA-JV to take immediate corrective action to ensure such does not reoccur in the future.
