Triangle Region Solid Waste Planners Committee Household Hazardous Waste October 28, 1993 AIR SAMPLING Air sampling will not generally be required at household hazardous waste pickup job sites because air concentrations of volatile substances will not be significant. Direct reading air sampling equipment such as detector Photovac-Microtip photoionization will be on site for use in case of spills or released of volatile organic compounds. If the scope of the project requires it. The Health & Safety Manager will make the determination to provide this determination and any other monitoring equipment the project would require. ACCESS CONTROL AND WORK ZONES Access to areas of chemical handling is controlled to prevent unnecessary public exposure to potentially harmful substances. Access control is done by clearly marking areas where chemical may be handled. Markings may include warning tape or barriers and caution signs. These sign may contain wording such as "NO SMOKING OR OPEN FLAMES, AUTHORIZED PERSONNEL ONLY" or similar warnings. In addition, Laidlaw personnel will be stationed in strategic locations and serve as checkpoint personnel to direct the flow of traffic and people. Prescribed operations will occur in work zones which are designed to prevent the migration of contaminants. Movement of personnel and automobile traffic between zones and into the chemical handling area will be limited by access control points. All traffic will be controlled so that the number of automobiles in the receiving area will be limited to a manageable number. The checkpoint (entry) area will be the principal focus for control of vehicle activity. The distance between these areas, and the size and shape of each have to be based on conditions specific to each location. The following criteria are used in establishing dimensions and boundaries. • Physical and topographical features of the work location • Weather conditions • Potential for release and exposure • Size of area needed to conduct operations • Decontamination procedures • Proximity to residential or industrial areas CONTINGENCY PLAN A contingency plan is necessary for the preplanning of potential emergencies that could occur. • TYPES OF INCIDENTS: It is not anticipated that an emergency situation will occur. However, preplanning is important to mitigate and minimize the effects of an emergency during the handling of hazardous materials. The more likely types if incidents possible are: Spills: A spill is an unintentional release of materials in a quantity that is sufficient to cause environmental or personal harm. Laidlaw will take steps to prevent a spill from affecting the environment by developing a Spill Response Plan. Laidlaw Environmental Services 36
