Welding and Hot Work, such as brazing or grinding present a significant opportunity for fire and injury. All precautions described in this program must be applied prior to commencing any welding or hot works by college employees and/ or contractors. Welding, cutting and use of torches shall comply with this section, NFPA 51B and OSHA 29 CFR 1910.252.

A designated area shall be a specific area designed or approved for such work, such as maintenance shop or a detached outside location that is of noncombustible or fire resistive construction, essentially free of combustible and flammable contents and suitable segregated from adjacent areas. All designated areas for welding will be inspected yearly and must display a copy of the permit in the approved area at all times as well as warning signs to alert others of the activities and dangers associated in these areas.
A permit required area shall be an area that is made fire safe by removing or protecting combustibles from ignition sources. Hot work permits shall not be allowed in the following areas: "Areas not authorized by Public Safety or Department Administration."

Hot Work Supervisor
A Hot Works Supervisor is needed to issue a hot works permit. The supervisor will inspect the area and receive a defined instruction on what the work will involve. Hot Works Supervisors must receive a Hot Works Training Program, which is offered on a yearly basis through the Safety Core Committee.
Hot Works Training Program
This program will be given yearly to all Hot Works Supervisors and is intended to be a yearly refresher course and review of the hot works policies. The Safety Core Committee will provide the instructor and scheduling for the program.
