Energy Savings Plus Health | INDOOR AIR QUALITY GUIDELINES FOR MULTIFAMILY BUILDING UPGRADES 65 LEAD Assessments Actions Determine whether building upgrade activities will expose workers to lead dust (for example, from lead paint used in buildings constructed before 1978), according to the Assessment Protocols outlined in Priority Issue 3.0 Lead. • If the facility was built before 1978, the existing paint is assumed to contain lead, unless EPA-approved testing methods show otherwise, and building upgrade activities must comply with EPA's RRP Program Rule requirements at 40 CFR Part 745 and the OSHA rule at 29 CFR Part 1926.62. • See OSHA's publication Lead in Construction for information on OSHA requirements to protect construction workers from lead hazards. MOLD Assessments Actions Determine whether workers will be exposed to mold. • All suspected moldy areas should be remediated by properly trained individuals. Moisture problems need to be identified and fixed or mold will return. If mold is expected to be disturbed during activities, immediately bring this to the attention of the site manager. Refer to OSHA's A Brief Guide to Mold in the Workplace; NIOSH's Recommendations for the Cleaning and Remediation of Flood-Contaminated HVAC Systems; EPA's Mold Remediation in Schools and Commercial Buildings; the American Conference of Government Industrial Hygienists' Bioaerosols: Assessment and Control; the American Industrial Hygiene Association's Recognition, Evaluation, and Control of Indoor Mold; or the Institute of Inspection, Cleaning and Restoration Certification's S520 Standard and Reference Guide for Professional Mold Remediation. • See EPA's Molds and Moisture website for additional information on mold remediation. POLYCHLORINATED BIPHENYLS (PCBs) Assessments Actions Determine whether workers may be handling PCB-containing or PCB-contaminated building materials, including fluorescent light ballasts and caulk. • See EPA's PCB-Containing Fluorescent Light Ballasts Web page for information on proper maintenance, removal and disposal of PCB-containing fluorescent light ballasts. If leaking ballasts are discovered, wear protective clothing including chemical-resistant (nitrile) gloves, boots and disposable overalls. • See EPA's Steps to Safe Renovation and Abatement of Buildings That Have PCB Containing Caulk website for information on this topic. Work practices to help ensure worker and occupant safety include employing protective measures (both interior and exterior), complying with occupational protective regulations, communicating with building occupants/third parties, setting up the work area to prevent the spread of dust, using appropriate tools that minimize the generation of dust/heat, and leaving the work area clean. SPRAY POLYURETHANE FOAM (SPF) Assessments Actions Determine whether workers will be using SPF, which may contain chemicals such as isocyanates (e.g., methylene diphenyl diisocyanate), amines, flame retardants and other additives. There are three main types of SPF products (two-component high pressure, two-component low pressure and one-component foam), each of which has different applications. Determine which of the three main types of SPF products will be used. • Applicators, crews and building occupants in the work area are required to use protective equipment to prevent exposure to isocyanates and other SPF chemicals. Protective equipment requirements vary depending on the type of SPF product. • Review label and product information for ingredients, hazards, directions, safe work practices and precautions. • Ensure health and safety training is completed and safe work practices are followed to prevent eye, skin and inhalation exposures during and after SPF installation. • Exercise caution when determining a safe re-entry time for unprotected occupants and workers based on the manufacturer's printed recommendation. If occupants or workers experience breathing problems or other adverse health effects from SPF application, seek immediate medical attention. • See OSHA's Green Job Hazards website for additional information on the hazards associated with SPF. • See EPA's Spray Polyurethane Foam (SPF) home website for additional information. • See the American Chemistry Council's Spray Polyurethane Foam Health and Safety website for additional information.
