ENVIRONMENTAL IMPACT
BUILDING A BASIC SPILL RISK PICTURE
Before implementing specific controls, organizations should first understand their site-specific risks. They should begin by taking stock of any fuels, oils, chemicals, and waste materials stored or used on-site. Next, they should consider where spills could occur, paying particular attention to high-risk areas such as loading docks, outdoor storage areas, chemical mixing zones, and waste-handling areas. They should also assess where any spill runoff could travel, such as nearby drains, soil, or water sources.
Additionally, referring to the Safety Data Sheets of substances can help organizations identify the hazards associated with different concentrations and properties of pollutants, as well as the potential consequences of a spill.
PREVENTING POLLUTION AT THE SOURCE
Once spill risks are understood, organizations can begin addressing them through targeted prevention measures, including reducing hazards at the source. Specifically, employers should minimize the amount of hazardous materials used or generated during routine operations to reduce the likelihood of large-volume spills. Keeping fewer hazardous materials on-site also minimizes waste-disposal needs, reduces storage requirements, and lowers handling risks( e. g., fewer containers need to be opened or moved, reducing opportunities for spills).
Pollution can be reduced by several means, such as upgrading process equipment to minimize leaks, overflows, or mechanical failures; using higher-quality or more efficient raw materials that generate less waste; and working with suppliers to coordinate deliveries so large volumes of fuels or chemicals do not need to be stored at any one time.
Organizations should also limit the amount of hazardous material employees are allowed to handle at once and improve fluid-dispensing controls and tank and equipment filling procedures( e. g., by installing controlled-flow nozzles and adding shut-off valves or drip trays). Additionally, staff should be taught to dispense hazardous liquids carefully to conserve resources and lower the risk of pollution.
EVERYDAY SPILL PREVENTION PRACTICES
Alongside source-reduction efforts, a range of practical day-to-day measures can further reduce spill risk. Organizations should consider the following spill prevention practices:
• Good container management: Hazardous materials should be stored in suitable containers, clearly labeled with the type and quantity of the substance, and kept in a secure storage area away from sources of ignition. Employees should visually inspect storage containers for cracks, gaps, discoloration, drip marks, or other signs of wear. Worn containers should be replaced immediately.
• Housekeeping discipline: Good housekeeping practices, orderly work areas, and neatly stored tools and equipment can make it easier for employees to spot leaks, damaged
