4.1 JOB ANALYSIS
The first step in the hot Lapping work process is establishing What needs to be accomplished, how the associated work is to be done, and whether hot Lapping is appropriate. 11w general review process is shown in Figure I. It is important to recognize that hot Lapping “by definition” involves hot work on equipment in service. A work scope analysis should be performed to determine if alternates to hot tapping exist within reasonable engineering and economic bounds, and whether hot tapping is appropriate (see 4.2).
lt after review, hot lapping is indeed required, the following approach confonns to good practice and regulatory requirements:
a. Since the work cannot be moved, a review shall determine whether fire hazards in the vicinity can be moved to a safe place.
h. Essentially the decision of who is a “competent person” becomes a performance oriented management decision, evaluating varied skills and knowledge for each category.
c. All precautions used for hot work should be followed.
Since hot tapping work can not be done except by performing hot work in place, the work area and each activity should be closely analyzed for hazards, such as the potential hazards discussed in this publication or on the MSDSS relevant to the materials involved (see Section 5). Along with the safeguards in step “c” above this should minimize the risk that hot work may provide a source of personnel exposure or ignition hazards which could lead to a fire or explosion. The consequences of each hazard should be carefully weighed along with unexpected conditions that might occur during hot work.
Contingenc plans should 1w put into place for tire lighting. personnel evacuation. anclor alternate methods (such as changes in plant operations) to finish the hot work without incident. Appendix D provides an example of a hot tap eipncy action contingency plan.
4.2 REVIEWING WHETHER HOTTAPPING IS APPROPRIATE
4.2.1 Determining Whether Hot Tapping is Appropriate
The esample flow chart in Figure 2 shows some of the thought required in making the decision that use of hot tapping is appropriate. OSI-IA 1910.147 “Control of Hazardous Energy” LockouuTagouu provides a specific eseinpiton for performing hot tapping. with several criteria which must be met to satisfy that this is both needed and safe. These criteria are:
a. continuity of service is essential;
h. shutdown of the system is impractical;
c. documented procedures are followed:
d. special equipment is used which will provide proven
effective protection for employees.
As indicated in Figure 2, if all four of these criteria cannot be met then hot lapping should not be done and the work Iflust he performed in confonnance with the requirements of the OSHA LockoutiTagoui regulation. For work on equipment subject to other regulations (federal or state OSHA Process Safety or DOTI there may well be other regulatory requirements.
4.3 JOB-SPECIFIC HOT TAPPING REVIEW FOR WORK AUTHORIZATION
4.3.1 Decision Process for Authorizing Hot Tapping
The analysis associated with Figure 2 covers both good practice and addresses the OSHA regulatory aspects relative to LockoutiTagout. Figure 3 einphasites the facility decision- making pnwess. First, as a special subset of work on equipment in service, the immediate safety coasldcrati(ms must 1w considered for accomplishing the work. Potential emergency response needs can 1w reviewed (sec Appendix D). Then, since this process enphasitcs communication among knowledgeable decision makers, the potential immediate and longer 1cm-rn impact on other parts of the organitation can be judged. For instance, this review prior to authoriiing the hot tap work provides opportunity for review of “change” which might be subject to “management of change” requirements or whether the equipment change waImmlts a Process Haiards Analysis (PHA).
