Cleaning a pre-1978 rental property in Maryland to make it lead-safe requires specific precautions and procedures to minimize lead exposure. Here are the general steps you can follow:
Initial Inspection: Hire a certified lead inspector to assess the property for lead-based paint hazards. This inspection will help identify areas of concern and guide your cleaning efforts.
Containment: Before starting any cleaning activities, establish proper containment measures to prevent lead dust from spreading to other areas of the property. This may involve sealing off the work area with plastic sheeting and using temporary barriers.
Personal Protective Equipment (PPE): Wear appropriate personal protective equipment, including disposable coveralls, gloves, and respirators with a HEPA filter, to protect yourself from lead dust exposure.
Wet Cleaning: Use wet cleaning techniques to minimize the generation of lead dust. Avoid dry sweeping, sanding, or using abrasive methods that can release lead particles into the air. Instead, use damp mops, wet cloths, or HEPA-filtered vacuum cleaners to clean surfaces.
Surfaces and Objects: Focus on cleaning surfaces and objects that are frequently touched or chewed on by occupants, such as windowsills, door frames, floors, and toys. Pay extra attention to areas with deteriorated or peeling paint.
Cleaning Solutions: Use mild, phosphate-free detergents and cleaning solutions to clean surfaces. Avoid using abrasive cleaners that can release lead dust or damage the paint.
Dust Removal: Regularly clean up any visible dust or debris using wet methods, such as wet wiping or mopping, rather than dry dusting.
Filters and Ventilation: Clean or replace filters in HVAC systems regularly to prevent lead dust circulation. Maintain proper ventilation to minimize the concentration of lead dust in the air.
Proper Waste Disposal: Dispose of cleaning materials, dust, and debris as hazardous waste according to local regulations. Seal them in heavy-duty plastic bags and label them appropriately.
Post-Cleaning Verification: After completing the cleaning process, consider hiring a certified lead inspector for a clearance examination to ensure that lead hazards have been adequately addressed.
Remember, these are general guidelines, and it's crucial to consult the official regulations and guidelines provided by the Maryland Department of the Environment for specific cleaning procedures and any updates or changes to the requirements.
