1.0 PURPOSE:
The City of Renton recognizes that there is a potential for injury to people and damage
to property that can result from fire or sparks that arise when hot work is performed
outside of a designated safe hot work area. This operating procedure establishes a
permit authorization system to ensure that all hazards are evaluated and that
appropriate safety measures and controls are taken prior to and during any operation
that uses an open-flame or spark-producing apparatus.
2.0 REFERENCE:
WAC 2 296-809-800
3.0 POLICY:
This policy, through the Hot Work Program and the authorizing Permit (see Attachment
A), establishes the means to assess the work area and the planned hot work activity to
ensure sufficient and necessary controls are in place to prevent a fire. Hot work will
only be performed in areas that are or have been made fire safe. Where fire prevention
precautions (such as a fire suppression system or a fire or smoke detection system) are
not sufficient, a fire watch person shall be assigned to monitor the area for fire, as
needed. Any work involving burning, welding, torch cutting, grinding where sparks are
produced, soldering, or brazing in construction, maintenance and fabrication activities
shall follow the City of Renton Hot Work Program. The City also has a written
authorization (Hot Work Permit; see Attachment A) which must be completed prior to
any hot work when operations will be performed in a confined space that can provide a
source of ignition, such as riveting, welding, cutting, burning, and heating. The City of
Renton Hot Work Program further explains the conditions where the Hot Work Permit
is required.

in suspension of competent person authority and possible disciplinary action.
