Brownfield Site Visits An Assessment of Safety and Health Hazards Johanna Hollingsworth, MPH HCI-ATL, LLC. Germantown, MD May 7, 2008
2 Purpose of Brownfields Visits Identify the types of work operations performed at Brownfield sites Identify existing and potential safety and health hazards at the sites Provide compliance guidance and corrective actions to the sites
3 Background of Sites Visited Visited two sites that were previous industrial facility locations A manufacturing site for aluminum consumer and industrial products; later a car and materials storage location A manufacturing site for steel vehicle frames among other steel automotive products
4 Conditions and Considerations Site Operations and Hazardous Conditions Safety & Health Considerations for Forthcoming Site Operations Additional Considerations
Site Operations and Hazardous Conditions
6 Building Demolition Lack of an engineering survey prior to demolition Materials dropped outside of structure without chutes or alternative effective protection
7 Fall Protection During Building Demolition Wall openings unprotected Improperly constructed guardrails Floor holes not guarded or improperly guarded Falling object protection not provided Access stairways not maintained in safe condition
8 Improper Floor Cover No Fall Protection Site Visit Photographs
9 Material Handling – Heavy Equipment Noise exposure likely exceed permissible exposure limits Eye protection necessary for flying materials (site in compliance)
10 Electrical Equipment Cords frayed or worn
11 Hazardous Substances Heavy metals such as lead, chromium, and arsenic Volatile chemicals such as benzene and toluene Organic compounds such as PCBs in water pits and soil Asbestos in building materials and electrical components
Safety & Health Considerations Forthcoming Site Operations
13 Protection of Employee Entrances Sidewalk sheds/canopies to protect against falling objects during building demolition
14 Removal of Building Footers Support systems may be necessary during excavation to protect employees
15 Rock Crushing Operations (Crushing of demolished building materials) Guarding of mechanical hazards Implementation of lockout/tagout procedures Protection of employees from excessive noise and dust (silica/ nuisance) levels
16 Removal of In-ground Concrete Pits Potential excavation hazards and need for structural support to protect workers Potential confined space hazards
17 Removal of Concrete Slabs Protection of employees from excessive noise levels Protection of employees from flying objects resulting from excavation hammer and other heavy equipment operations
18 Underground Storage Tank Removal Protection of workers from excavation hazards (shielding, benching, sloping) Use and selection of proper rigging equipment Protection of nearby utility poles and railway lines
Additional Considerations
20 Protection of Public Streets and Pedestrians Building demolition potential impacts city street and sidewalks Consideration for traffic and pedestrian stoppage
21 Potential Bloodborne Pathogen Exposure Illicit drug use in buildings Exposure to blood or OPIM during trash removal and cleanup should be considered
22 Layout of Work Operations Size of the site is restrictive Consider layout of operations to enable safety of workers on foot To the extent possible, limit backing of heavy equipment to reduce operator blind spots Communicate locations of entrances and exits and flow of work operations to on-site workers
23 Workplace Violence Illicit drug use and trespassing Procedures for handling such instances should be addressed with site workers
24 First Aid Care If designated first aid provider onsite, then proper training of provider and supplies must be available Designated first aid providers must be protected from bloodborne pathogen hazards
