We had this question from a reader and wanted to post for all to read.
Would a proper tailboard briefing conducted before a confined space entry be sufficient for identifying hazards that may be encountered by the entrants or the rescue team?
It’s true that a tailboard briefing should be an integral part of the larger overall preplanning for a confined space entry. However, well in advance of the entry, a detailed “hazard analysis” of the space should be performed.
A hazard analysis is used to identify the types of hazards, lock-out/tag-out needs, PPE required for entry, method of entry and important rescue considerations. In fact, OSHA requires these written assessments to be completed prior to an entry being made and the confined space permit acts as a secondary written assessment performed at the time of the entry. Here are some OSHA references concerning this topic…
The employer shall verify that the space is safe for entry and that the pre-entry measures required by paragraph (c)(5)(ii) of this section have been taken, through a written certification that contains the date, the location of the space, and the signature of the person providing the certification. The certification shall be made before entry and shall be made available to each employee entering the space or to that employee’s authorized representative.
Identify and evaluate the hazards of permit spaces before employees enter them;
Develop and implement the means, procedures, and practices necessary for safe permit space entry operations;
The tailboard briefing should be used to confirm or reinforce the information already gathered in the hazard analysis. Because it deals with an individual space at the time of entry, the tailboard briefing is also a very useful tool in finding out if conditions have changed since the hazard analysis was completed.
So, the bottom line… having a detailed hazard analysis for each space that includes a detailed rescue preplan allows a rescue team to review and prepare for potential problems well in advance. Reviewing this information at a tailboard briefing just prior to the entry helps to remind everyone of the possible hazards, the proper precautions, and the potential solutions should an emergency occur.
