Subpart Q—Welding, Cutting, and Brazing

In this section, we discuss an important procedure applicable to ensuring that confined space operations are conducted safely hot work permit procedures. In addition to ensuring that any type of hot work to be performed in confined spaces is accomplished in a safe manner by utilizing hot work permit requirements, other workplace operations might require the use of hot work permit procedures. 

In the performance of hot work in the workplace, OSHA 29 CFR 1910.119, Process Safety Management of Highly Hazardous Chemicals, requires the following The employer shall issue a hot work permit for hot work operations conducted on or near a covered process (including confined spaces). The permit should document that the fire prevention and protection requirements in 29 CFR 1910.252(a), Fire Prevention and Protection, have been implemented prior to beginning the hot work operations it should indicate the dates authorized for the hot work and it should identify the object on which hot work is to be performed. The permit must be kept on file until completion of the hot work operations. 

Typically, the organizational safety official is responsible for implementing and managing the hot work permitting procedure. The primary elements required to be incorporated into a viable hot work permit system include a standard operating procedure consisting of (1) a written procedure, (2) a permit, (3) worker training, and (4) fire watch provisions. 

Combustible floors are wetted down and covered with damp sand, metal, or other shields. 

No combustible material or flammable liquids are within 35 feet of the work. 

Arc welding and its unique precautions are covered by this regulation. This includes grounding, care of cables, and care of electrode holders. As with all welding and cutting operations, appropriate PPE and safety are addressed in this subpart. 

Fire prevention is an important part of welding and cutting and such work is not to be performed near flammable vapors, fumes, or heavy dust concentrations. Fnefighting equipment must be readily 

Subpart R deals with industries singled out by OSHA that need to be addressed in industry-specific standards. These industries include pulp, paper and paperboard mills, textile mills, bakeries, laundries, and sawmills. It also includes industries such as pulpwood logging, telecommunications, electric-power generation, transmission, and distribution and grain-handling facilities.
