Health and Safety Code §341.0357

(a) The owner of any device having the appearance of a fire hydrant that is located in a place that an entity responsible for providing fire suppression services in a fire emergency would expect a fire hydrant to typically be located shall paint the device black if the device is nonfunctioning or otherwise unavailable for use by the entity providing fire suppression services in a fire emergency. The owner may place a black tarp over the device instead of painting the device black as required under this section if the device is temporarily nonfunctioning, or temporarily unavailable for use in a fire emergency, for a period not to exceed seven days. (b) For purposes of this section, a device is considered to be nonfunctioning if the device pumps less than 250 gallons of water per minute. (c) This section does not apply within the jurisdiction of a governmental entity that maintains its own system for labeling a device having the appearance of a fire hydrant that is nonfunctioning or otherwise unavailable for use in a fire emergency. (d) This section does not apply within the jurisdiction of a governmental entity described by Section 341.03571 (b).
