4.8 REQUIRED LEAD-BASED PAINT MANAGEMENT PROCEDURES:

Appropriate OSHA worker protection is the responsibility of the employer. All projects will be monitored and inspected by BOS/CEV. The purpose of these instructions is to provide guidance to safely remove or encapsulate lead-based paint without causing a hazard. All work must be performed in accordance with OSHA, MDEQ and any local regulations for all work and disposal. The regulations are divided into two parts; a) lead-based paint on non-child occupied/non-target housing buildings and b) child occupied/target housing buildings.

4.8.1 Non-child occupied/ commercial buildings:

4.8.1.1 For non-child-occupied/commercial buildings, the minimum requirement for Contractors is to protect workers IAW OSHA requirements, use poly lay-down to collect paint chips, and turn into BOS/CEV for disposal. At minimum the supervisor of the project should be LBP trained and supply proof of certification before work begins. The Contractor shall notify BOS/CEV before start of any project. Contractor must place plastic on the ground sufficient to capture all loosened paint chips and control water run-off. Removal methods preferred at Keesler AFB are the use of an approved chemical stripper or wet sanding methods for better collection of LBP chips and waste. These processes minimize lead dust and allow for maximum collection of LBP chips.

4.8.1.2 The Contractor shall meet with BOS/CEV prior to beginning the project to discuss protective measures, best management practices (BMP’s), any landfill disposal, and maintenance of chips and their collection (until they are turned over to BOS/CEV).

4.8.1.3 Any buildings with LBP, if bead blasted to remove old paint, shall be supervised by a Contractor with proper training. Bead blasting upon prior approval only (see preferred method above).

4.8.1.4 The Contractor, under OSHA rules, must comply with the lead based paint rules (including notification to BOS/CEV, if the job is abatement), certify appropriate training, and maintain personal monitors on workers until it is demonstrated there is no airborne lead risk.

4.8.1.5 BOS/CEV will inspect all projects involving LBP removal and any required documentation must be provided to BOS/CEV prior to beginning work.

4.8.2 Child-occupied/target housing buildings:

4.8.2.1 Any child-occupied/target housing building older than 1978 must be painted using Lead Paint Protocol, including poly-lay-down, collection of paint chips, and the Contractor must always have a minimum of lead hazard training for all workers. The Contractor shall notify BOS/CEV before start of any project.

4.8.2.2 A paint Contractor must collect paint chips in their own clean buckets and have BOS/CEV dispose (if contract requires BOS/CEV dispose). Contractor must place plastic on the ground sufficient to capture all loosened paint chips and control water run-off.

4.8.2.3 For work on child-occupied/target housing buildings falling under the Lead Paint Protocol, the Contractor must use water or amended water when scraping or chipping. All members of the Contractor’s work force must wear protective clothing and comply with all OSHA rules and regulations. OSHA regulation compliance is the employer’s responsibility and is subject to inspection by OSHA and the Base. Suggested PPE include foot protection (ex. Rubber Boots) worn while on the poly. All PPE shall be stored on the protective plastic when not in use and shall be decontaminated or disposed of in an approved manner. Minimum respiratory protection for any OSHA “trigger task” such as scraping, manual sanding, demolition, heat gun and power tool cleaning is a half-mask air purifying respirator (APR) with HEPA filter that is at least 99.97 percent efficient (i.e., P100). APR fit tests evidence must be provided for inspection. Other circumstances may warrant higher protection. PPE determination is the responsibility of the Contractor.
