Lead-Containing Materials Guidelines

14 Lead-Containing Materials ¤ ¤ Mechanized sanding equipment with dedicated HEPA filtered exhaust systems Prohibited Methods The following work methods are prohibited and will not be allowed: • Use of a heat gun generating temperatures exceeding 700 degrees Fahrenheit • open flame torching • dry abrasive blasting using sand, grit or any other particulate • use of chemical strippers not approved by EH&S • mechanized sanding without HEPA filtered collection systems Interior Work When performing interior work follow these guidelines. • Notify the building supervisor and occupants where work involving lead will take place. • Conduct work involving lead-containing materials at times when the area is unoccupied. • Place 6-mil polyethylene sheeting a minimum of 6 feet horizontally out in all directions from the work area to cover any immovable objects. • Personal protective equipment (PPE) must be used, and at a minimum should include half face respirator with HEPA filters, disposable clothing and gloves. Shoe covers are necessary to avoid tracking lead dust and waste outside the immediate work area. • HEPA vacuums, disposable towels and wash-up facilities must be available to employees at the work site. Clean-up materials should be kept away from the immediate work area, but must be close enough to allow quick cleanup of employees and equipment. All reusable equipment (HEPA vacuums, scrapers, screw drivers, etc.) must be properly cleaned at the end of each day. • The work area itself must be demarcated and barricaded using disposable danger tape and “Lead Danger” warning signs bearing the following legend: • Use a HEPA vacuum to clean any accumulated dust from the work area prior to beginning the maintenance activity. Do not sweep or brush potential lead-containing dust. • Use care to minimize the production of dust from scraping or sanding. Use either wet sanding/scraping or HEPA-filtered
