Smoke, Carbon Monoxide Detectors, and Fire Extinguishers
Action / Allowability: Installation of smoke/CO detectors is allowed where detectors are not present or are inoperable. Replacement of operable smoke/CO detectors is not an allowable cost. Providing fire extinguishers is allowed only when solid fuel is present.
Testing: Check for operation.
Client Education: Provide client with verbal and written information on use of smoke/CO detectors and fire extinguishers where allowed.
Training: Where to install detectors. Local code compliance.
Solid Fuel Heating
Action / Allowability: Maintenance, repair, and replacement of primary heating unit is allowed where occupant health and safety is a concern. Maintenance and repair of secondary heating units is allowed.
Testing: Required inspection of chimney and flue and combustion appliance zone depressurization.
Client Education: Provide safety information including recognizing depressurization.
Training: How to perform CAZ depressurization test and proper inspection.
Space Heaters, Stand Alone Electric
Action / Allowability: Repair, replacement, or installation is not allowed. Removal is recommended.
Testing: Check circuitry to ensure adequate power supply for existing space heaters.
Client Education: Inform client of hazards and collect a signed waiver removal is not allowed.
Training:Awareness of Guidance.
Space Heaters, Unvented Combustion
Action / Allowability: Removal is required except as secondary heating source where the unit conforms to ANSI Z21.11.2. Units that do not meet ANSI Z21.11.2 must be removed prior to weatherization but may remain until a replacement heating system is in place.
Testing: Testing for air-free carbon monoxide (CO) is allowed. Check units for ANSI Z21.11.2 label.
Client Education: Inform client of dangers of unvented space heaters; CO, moisture, NO2, CO can be dangerous even if CO alarm does not sound.
Training: How to perform air-free CO testing. Understanding the dangers of unvented space heaters.
Space Heaters, Vented Combustion
Action / Allowability: Should be treated as furnaces.
Testing: Venting should be tested.
Client Education: Not applicable.
Training: Proper testing methods for safe operation (draft and CO) should be conducted and for steady state efficiency if possible.
Spray Polyurethane Foam (SPF)
Action / Allowability
when working within the conditioned space or when SPF fumes become evident within the conditioned space. When working outside the building envelope, isolate the area where foam will be applied, take precautions so that fumes will not transfer to inside conditioned space, and exhaust fumes outside the home.
Testing: Check for penetrations in the building envelope. Sensory inspection inside the home for fumes during foam application.
Client Education: Provide notification to the client of plans to use two-part foam and the precautions that may be necessary.
Training: Training on the use of various products with specifications for each application type. MSDS Sheets. Temperature sensitivity.
Action / Allowability: 2010 (or most current) ASHRAE 62.2 is required to be met to the fullest extent possible when performing weatherization activities (must be implemented by January 1, 2012). Implementing ASHRAE 62.2 is not required where acceptable indoor air quality already exists as defined by ASHRAE 62.2. Existing fans and blower systems should be updated if not adequate.
Testing: ASHRAE 62.2 evaluation, fan flow, and follow up testing are required to ensure compliance.
Client Education: Provide client with information on function, use, and maintenance of ventilation system and components. Include disclaimer that ASHRAE 62.2 does not account for high polluting sources or guarantee indoor air quality.
: ASHRAE 62.2 training required including proper sizing, evaluation of existing and new systems, depressurization tightness limits, critical air zones, etc. To see ASHRAE FAQs, click here
Window and Door Replacement, Window Guards
Action / Allowability: Replacement, repair, or installation is not an allowable health and safety cost but may be allowed as an incidental repair or an efficiency measure if cost justified.
Testing: Not Applicable.
Client Education: Provide information on lead risks.
Training: Awareness of guidance.
