Flood protection, preparation, response and recovery
Flooding comes from many sources: heavy rains, melting snow, dam collapse and levee failures, ice jams and tidal storm surges. Floods can be sudden, but others can give days of warning. Being located within a flood zone certainly can put a business at risk, but being outside an established zone doesn’t guarantee safety. Prudent business owners will be familiar with the flood history and base flood elevations of the bodies of water nearby, coupled with an action plan should a flood occur. Recognize that just because a body of water hasn’t flooded before, does not mean that it never will. Ice jams, unusual heavy snows with rapid thaws, new construction, and new roads or bridges can all alter flood potential. Note that fires at damaged sites are not uncommon after a flood due to spilled hazardous materials, floating flammable gas cylinders, damaged electrical equipment, cutting and welding repairs, and other hazards.
Protection and preparation
- Alert employees, emergency response teams and management.
- Maintain a flood watch center.
- Place sand bags at low points and at doors, then follow planned placements to seal off buildings.
- Shut down processes, boilers and furnaces. Coat machinery with rust-preventive materials. Shut off electrical power except the power-operating sump pumps, fire pumps and other critical equipment.
- Move electronic equipment, critical tools and equipment, vital business records and other damageable materials to higher levels or other locations. Verify that stock, materials and equipment are skidded; remove critical equipment and tools from basements.
- Close gas and propane lines from outside site tanks. Close sewer and drainage line valves. Secure all hazardous materials and shut off their supply piping systems.
- Bring inside or tie down equipment, tools, cans, barrels and other containers, furniture and other unsecured items.
- Move trucks, cars and other mobile equipment to higher ground.
- Verify that fire protection equipment is operational.
- Prepare emergency equipment, check fuel levels in generators and pumps, conduct start tests, check flashlights and prepare other provisions.
- Evacuate the facility in a timely manner to safeguard all employees. Follow all orders from authorities.
Provide for safe shelter, escape boats, life jackets, non-perishable food, water, lighting, radios and other necessary items for any emergency personnel who will remain in the facility during the flood.
- Survey site for damage.
- Activate business continuity plan.
- Restore any damaged fire protection systems.
- Maintain pumps.
- Attend to hazardous material spills, floating cylinders, dislodged tanks and other dangerous items.
- Begin salvage efforts.
- Remove standing water. Begin dehumidification.
- Remove mud, silt and combustible debris.
- Have all electrical systems, process systems, and heating equipment inspected by experts before repowering. Replace submerged circuits.
- Have electronic equipment serviced by restoration vendors.
- Replace motors on submerged equipment and tools. Disassemble power trains, bearings and other components. Dry, remove silt and lubricate. Recoat with rust preventatives.
- Use hot work permit program for any welding and cutting.
