  4. Frozen Surfaces: Sub-freezing temperatures can cause water used for wetting surfaces (to prevent lead dust from becoming airborne) to freeze. It can complicate wet removal methods and increase the risk of lead dust generation.

Best Practices For Containing, Removing, & Disposing Of Lead-Contaminated Materials In Cold Weather

  1. Containment: Enclose the work area with plastic sheeting to prevent lead dust from spreading. Ensure that the containment is airtight and that negative air pressure is maintained to prevent the escape of lead dust.
  2. Personal Protective Equipment (PPE): Workers should wear appropriate PPE, including disposable coveralls, respirators with HEPA filters, gloves, and eye protection, to minimize exposure to lead dust and the cold.
  3. Wet Methods: Use wet removal methods to keep lead dust from becoming airborne, which involves wetting surfaces before, during, and after removal to suppress dust.
  4. Heating: Implement heating systems within containment areas to maintain adequate temperatures for lead paint abatement. It prevents freezing of water used for wetting surfaces and ensures worker comfort.
  5. Ventilation: While limited in winter, ventilation is essential to remove contaminated air. Utilize HEPA-filtered exhaust systems to maintain air quality within containment areas.
  6. Cleaning: Implement thorough cleaning procedures using HEPA-filtered vacuums and wet cleaning methods. Clean surfaces regularly to minimize the accumulation of lead dust.
  7. Waste Disposal: Lead-contaminated waste should be labelled, sealed, and disposed of following hazardous waste regulations. Transport it to licensed hazardous waste disposal facilities.

Cold & Mould: Addressing Winter Mold Growth

Mold growth is a persistent issue that doesn’t pause during the winter months, and in some cases, it can be exacerbated by cold and damp conditions. A hazardous materials assessment is crucial in identifying and addressing mould problems during winter construction projects. Here’s a detailed explanation of the relevant considerations:

Mould Growth In Winter

  1. Cold Surfaces: During winter, interior surfaces may become cold due to low outdoor temperatures. When warm, moist indoor air comes into contact with these cold surfaces, condensation can occur. It provides the moisture that mould needs to thrive.
  2. Reduced Ventilation: In winter, buildings are often sealed to retain heat, reducing ventilation. Stale indoor air with high humidity levels can encourage mould growth, especially in areas with poor airflow.

Strategies For Identifying Moisture Sources

  1. Thermal Imaging: Thermal imaging cameras can identify areas with temperature differentials, indicating potential moisture issues. Cold spots on walls or ceilings may suggest areas where condensation occurs.
  2. Humidity Monitoring: Continuously monitor indoor humidity levels. Elevated humidity readings in specific areas can indicate moisture problems that may lead to mould growth.
  3. Visual Inspection: Careful visual inspection can reveal water stains, leaks, or signs of condensation on surfaces. These are clues to potential moisture sources.

Winter Mold Remediation Methods

  1. Containment: Isolate the work area to prevent mould spores from spreading to unaffected parts of the building. Use plastic sheeting and negative air pressure machines to maintain containment.
  2. Heating: Maintain a suitable indoor temperature for mould remediation. It prevents further condensation and ensures that cleaning and disinfection processes are effective.
  3. HEPA Filtration: Use HEPA-filtered air scrubbers to capture and filter airborne mould spores and prevent them from spreading.

Preventive Measures

  1. Proper Insulation: Adequate insulation can help prevent condensation by keeping interior surfaces warmer. Insulate walls, ceilings, and windows to reduce the potential for moisture buildup.
  2. Ventilation: Encourage proper ventilation, even in winter. Introduce fresh outdoor air to reduce humidity levels indoors.
  3. Dehumidification: Dehumidifiers control indoor humidity levels, especially in areas prone to moisture buildup.
  4. Regular Inspection: Perform routine checks for leaks, water damage, and signs of mould growth, even in winter. Early detection allows for prompt remediation.
