FOREWORD This technical guide was prepared in response to increasing concerns over the requirements for through-penetration firestopping as mandated by codes, specified by system designers, and required by code officials and/or other authorities having jurisdiction. The language in the model codes, the definitions used, and the expectations of local code authorities varies widely among the model codes and has caused confusion in the building construction industry. Contractors are often forced to bear the brunt of inadequate or confusing specifications, misunderstandings of code requirements, and lack of adequate plan review prior to construction. This guide contains descriptions, illustrations, definitions, recommendations on industry practices, designations of responsibility, references to other documents and guidance on plan and specification requirements. It is intended to be a generic educational tool for use by all parties to the construction process. Firestopping Guideline • Second Edition iii FIRE AND SMOKE CONTROL COMMITTEE Phillip E.

The BAPI sensor measures these VOCs and indicates when a space is occupied just as well as a CO2 sensor. The advantage of the VOC sensor is that it measures air contaminants from other sources besides respiration, such as building materials, cleaners, perfumes and furniture and carpet VOC Duct Sensor off-gassing. Using this sensor for Demand Controlled Ventilation then is a way of achieving true indoor air quality, rather than just CO2 dilution. A further benefit is that it requires no additional work on your part. That’s because the sensor converts the VOC reading to a CO2 equivalent level. This lets you use ASHRAE’s CO2- based VRP schedule to ventilate. (More information on the CO2 equivalent output is available on our website or in the Application Notes at the end of this section.) The Duct Sensor samples duct air using an aspiration tube, while the Rough Service unit features a ventilated BAPI-Box and is ideal for areas such as outdoor air plenums, equipment rooms, green houses and warehouses. The VOC level is indicated as “Good, Fair or Poor” by three discrete green, yellow and red LED’s on the front of the unit. If the output reaches 2,000 PPM, the red LED VOC Rough Service Sensor will begin to flash because it has hit its maximum output.

    Hazards / Problems Associated with Fiberglass Duct Liner and HVAC Insulation

    Hazards / Problems Associated with Fiberglass Duct Liner and HVAC Insulation Guidance for Insulating New HVAC/Ductwork DC Indoor Air Quality Work Group Background Fiberglass (fibrous glass or glass wool) internal duct liner has been used as acoustical and thermal insulation in many Heating, Ventilation and Air Conditioning (HVAC) systems. Indoor Air Quality (IAQ) complaints may arise when the fiberglass internal duct liner deteriorates over time. Deteriorating fiberglass duct liner, which is typically black in color, can migrate through supply diffusers. The liner can deposit in occupied spaces and onto flat surfaces, where it can cause complaints and adverse health effects. Due to ongoing concerns about exposure to deteriorating fiberglass duct liner, the Indoor Air Quality Work Group of the UC Industrial Hygienists/Safety Committee has decided to address the issue and develop this guidance for the UC campuses. Adverse Health Effects 1. Fiberglass carcinogenicity has been studied and classified by the following organizations: • International Agency for Research on Cancer (IARC) has classified it as a possible human carcinogen • National Toxicology Program (NTP) has classified it as an animal carcinogen • American Conference of Governmental Industrial Hygienists (ACGIH) has classified it as an animal carcinogen (A3) • Environmental Protection Agency (EPA) has classified it as an animal carcinogen. Fiberglass, at a minimum, is an acute physical irritant to the skin, eyes, and upper respiratory tract. The following are occupational exposure limits for fibrous glass or glass wool fibers, developed by US and international agencies: AGENCY / ORGANIZATION EXPOSURE UNIT Cal/OSHA PEL, 2001 (as an 8 hr TWA) 1.0 f/cc ACGIH, 2008 TL V 1.0 f/cc A3 Safety & Health Committee, Bldg.
