Facilities Hotwork Procedures

Contact information

Hot Work is any work activity that generates a flame, heat or sparks such as soldering, brazing, welding, torch cutting or grinding.

An authorized FO&M employee is an employee that can perform assigned specific hot work tasks safely and be able to coordinate with FO&M Customer Support Center and the Alarm Shop. The authorized employee shall obtain necessary hot work permits from the UC Davis Fire Department, conduct fire watches and, for interior work, is knowledgeable in the installation and removal of smoke detector covers.

Scope:

This hot work procedure shall be followed by FO&M employees and on FO&M and A/E contracted projects that include any hot work activity inside or within 100 feet of campus buildings.

Non emergency hot work:

All non-emergency hot work must be scheduled at least 72 hours in advance with the FO&M Customer Support Center, the Alarm Shop and the UC Davis Fire Department. 

Advanced coordination and approval is needed with the FO&M Customer Support Center, the Alarm Shop and the UC Davis Fire Department to have any fire protection system remain de-activated overnight.

Fire Watch:

A fire watch must be conducted by the person performing the hot work or qualified designee for 30 minutes following the completion of any hot work under this procedure on campus.

Hot Work being performed by Authorized FO&M Employees:

•Responsibilities for Welding, Torch Cutting, Grinding

All FO&M employees must first call the Customer Support Center (752-1655) prior to scheduling any welding, torch cutting or grinding activity. The Customer Support Center will provide the requestor with additional hot work procedure information.

FO&M employees will coordinate with the FO&M Customer Support Center, the Alarm Shop and have a valid Hot Work Permit from the UCD Fire Department prior to starting any welding, torch cutting or grinding activity.

The FO&M Alarm Shop is responsible to determine the type of fire protection system present and whether an alarm technician is needed for zone de-activation.  In the case of a smoke detector type system, a trained FO&M employee may be authorized to use the “bag” method on smoke detector(s). If the “bag” method is used, it is critical to remove the bag from the smoke detector(s) as soon as the hot work activity is complete.

The UC Davis Fire Department shall be notified at the completion of hot work and fire watch activities.

 

•Responsibilities for Soldering and Brazing Activities:

FO&M employees performing soldering and brazing activities will follow the procedure for welding, torch cutting and grinding but a Hot Work Permit from the UCD Fire Department is not required.

•Hot Work in Confined Spaces:

All Hot Work in confined spaces are considered Permit Required Confined Space entries; they shall have a Hot Work Permit issued by the UCD Fire Department plus inform the FO&M Customer Support Center of the hot work activity.

•Other FO&M Activities That Could Affect Fire Protection Systems:

FO&M employees performing painting, demolition, ceiling tile removal/installation or any other activity that could negatively affect a fire protection system or device must consult and coordinate with the FO&M Customer Support Center and the Alarm Shop prior to starting the activity.

Smoke detectors systems: Only after review and proper approval, a trained and authorized FO&M employee can install/remove the protective cover(s) or bag(s) from smoke detectors.

Contract Work:

  • Responsibilities

For contract work on campus, FO&M and A/E Project Managers are responsible to ensure that they or their designees first call the FO&M Customer Support Center (752-1655) prior to scheduling any hot work. The Project Managers  are also responsible for initiating, either directly or through FO&M Customer Support Center, a Maximo Work/Sub Work Order(s) and coordinate with the FO&M Alarm Shop to identify the fire protection system in operation and to coordinate with the UC Davis Fire Department to request a Hot Work Permit.

Contractors are prohibited from altering, disabling or modifying any fire protection system, device or related fire protection equipment on campus. Only trained and authorized FO&M employees may disable (for Hot Work purposes) a fire protection device, deactivate a zone or use the bag method.

It is critical that as soon as any Hot Work is complete (including a fire watch for 30 minutes) the UC Davis Fire Department shall be notified and the fire protection system shall be reactivated or if “bag” method is used the bag(s) must be removed by an FO&M employee.

•Other Contracted Activities That Could Affect Fire Protection Systems:

The project manager overseeing contractors performing painting, demolition, ceiling tile removal/installation or any other activity that could negatively affect a fire protection system or device shall consult and coordinate with the FO&M Customer Support Center and Alarm Shop prior to starting the activity. 

Only after review and proper approval can a trained and authorized FO&M employee install/remove the protective cover(s) or bag(s) from smoke detectors.
