Fumigation and thermal insecticidal fogging operations within buildings, structures and spaces shall comply with this chapter.
Permits shall be required as set forth in Section 105.6.
The following words and terms shall, for the purposes of this chapter and as used elsewhere in this code, have the meanings shown herein.
FUMIGANT. A substance which by itself or in combination with any other substance emits or liberates a gas, fume or vapor utilized for the destruction or control of insects, fungi, vermin, germs, rats or other pests, and shall be distinguished from insecticides and disinfectants which are essentially effective in the solid or liquid phases. Examples are methyl bromide, ethylene dibromide, hydrogen cyanide, carbon disulfide and sulfuryl fluoride.
FUMIGATION. The utilization within an enclosed space of a fumigant in concentrations that are hazardous or acutely toxic to humans.
THERMAL INSECTICIDAL FOGGING. The utilization of insecticidal liquids passed through thermal fog-generating units where, by means of heat, pressure and turbulence, with or without the application of heat, such liquids are transformed and discharged in the form of fog or mist blown into an area to be treated.
Buildings, structures
and spaces in which fumigation and
thermal insecticidal fogging operations are conducted shall comply with the fire protection and safety requirements of Sections 1703.2 through 1703.7.
Fires, open flames and similar sources of ignition shall be eliminated from the space under fumigation or
thermal insecticidal fogging. Heating, where needed, shall be of an approved type.
Electricity shall be shut off.
Electricity in any part of the building, structure or space where operation of switches or electrical devices, equipment or systems could serve as a source of ignition shall be shut off.Exception: Circulating fans that have been specifically designed for utilization in hazardous atmospheres and installed in accordance with NFPA 70.
Electronic devices, including
portable equipment and cellular phones, shall be shut off.
Telephone lines shall be disconnected from telephones.
Sources of ignition shall be shut off
during the fumigation activity and remain shut off until the
ventilation required in Section 1703.6 is completed.
The fire code official and fire chief shall be notified in writing
at least 24not less than 48 hours before the building, structure or space is to be closed in connection with the utilization of any toxic or flammable fumigant. Notification shall give the location of the enclosed space to be fumigated or fogged, the occupancy, the fumigants or insecticides to be utilized, the person or persons responsible for the operation, and the date and time at which the operation will begin. Written notice of any fumigation or
thermal insecticidal fogging operation shall be
served with sufficient advance notice to the occupants of the enclosed space involved to enable the occupants to evacuate the premises.
given
to all affected occupants of the building, structure or space in
which such operations are to be conducted with sufficient
advance notice to allowthe occupants to evacuate the building,
structure or space. Such notice shall inform the occupants as to
the purposes, anticipated duration and hazards associated with
the fumigation or insecticidal fogging operation
Approved warning signs indicating the danger, type of chemical involved and necessary precautions shall be posted on all doors and entrances to the
premisesaffected building, structure or space and upon all gangplanks and ladders from the deck, pier or land to
thea ship. Such notices shall be printed in red ink on a white background. Letters in the headlines shall be
at leastnot less than 2 inches (51 mm) in height and shall state the date and time of the operation, the name and address of the person, the name of the operator in charge, and a warning stating that the
occupied premisesaffected building, structure or space shall be vacated
at leastnot less than 1 hour before the operation begins and shall not be reentered until the danger signs have been removed by the proper authorities.
Persons engaged in the business of fumigation or
thermal insecticidal fogging shall maintain and have available approved protective breathing apparatus.
During the period fumigation is in progress, except
whenwhere fumigation is conducted in a gas-tight vault or tank,
a capable, alert watcherresponsible watchperson shall remain on duty at the entrance or entrances to the enclosed fumigated space until after the fumigation is completed and the
premisesbuilding, structure or space is properly ventilated and safe for occupancy. Sufficient watchers shall be provided to prevent persons from entering the enclosed space under fumigation without being observed.
Occupants of the
building, structure or space to be fumigated, except the personnel
conducting the fumigation, shall be evacuated from such building, structure or space prior to commencing fumigation
operations.
Occupants in the building, structure or space to be
fogged, except the personnel conducting the insecticidal
fogging operations, shall be evacuated from such building,
structure or space prior to commencing fogging operations.
Thermal insecticidal fogging liquids with a flash point below 100°F (38°C) shall not be utilized.
Paper and other similar materials that do not meet the flame propagation performance criteria
of Test Method 1 or Test Method 2, as appropriate, of NFPA 701 shall not be used to wrap or cover a
building, structure or space in excess of that required for the sealing of cracks, casements and similar openings.
All openings to the
building, structure or space to be fumigated or fogged shall
be kept securely closed during such operation.
At the end of the exposure period, fumigators shall safely and properly ventilate the premises and contents; properly dispose of fumigant containers, residues, debris and other materials used for such fumigation; and clear obstructions from gas-fired appliance vents.
The use of carbon disulfide and hydrogen cyanide shall be restricted to agricultural fumigation.
