1. The SSO will verbally notify onsite personnel of the emergency and direct personnel. 2. If the emergency cannot be readily contained, extinguished, or controlled by onsite personnel, the SSO will call 911 and inform them of the location and details of the emergency situation. 3. The SSO will notify the Project Manager and Principal, if necessary. 4. The SSO, with the assistance of the Project Manager, will decide when to resume operations after an incident has been controlled. 13.1 Flammable Atmosphere In the event that CGI or OVM readings in work areas (outside tanks) exceed 10 percent LEL, work will be suspended, monitoring will be continued as necessary to isolate the area, and some or all of the following engineering controls will be implemented: 1. Contaminated soils will be sprayed down, if necessary, with deodorizing Chemicals to reduce vaporization of volatile organic compounds(VOCs) or permeation of other gases. 2. Vapors from pooled petroleum product will be suppressed, if necessary, by spraying with foam or an appropriate chemical suppressant. 3. Portions of the stockpiled soil will be covered with plastic sheeting. 4. Air movers will be used to ventilate areas of concentration to below 10 percent LEL. 5. Wells emitting excessive chemical concentrations will be ventilated, capped or shut in, as necessary. s 13.2 Toxic Atmosphere In the event that airborne concentrations of the chemicals of concern exceed the TLV, the above engineering control measures will be implemented to reduce concentrations to or below the TLVs, if practical. If such reduction is not possible, PPE will be used to limit worker exposure during operations. In the event that airborne concentrations of the chemicals exceed twice the TLV, work will be suspended and appropriate engineering controls will be implemented to reduce concentrations to or below twice the TLV.
