OHMRemediationServices Corp. HEALTH AND SAFETY PLANsize of the spill and the materials involved. If the spill is large (greater than 55 gallons) andinvolves a tank or a pipeline rupture, an initial isolation of at least 100 ft. in all directions willbe used. Small spills (less than or equal to 55 gallons) or leaks from a tank or pipe will requireevacuation of at least 50 ft. in all directions to allow cleanup and repair and to preventexposure. When any spill occurs, only those persons involved in overseeing or performingemergency operations will be allowed within the designated hazard area. If possible the areawill be roped or otherwise blocked off.If the spill results in the formation of a toxic vapor cloud (by reaction with surroundingmaterials or by outbreak of fire) and its release (due to high vapor pressures under ambientconditions), further evacuation will be enforced. In general an area at least 500 feet wide and1,000 feet long will be evacuated downwind if volatile materials are spilled. (Consult the DOTEmergency Response Guide for isolation distances for listed hazardous materials.)If an incident may threaten the health or safety of the surrounding community, the public willbe informed and possibly evacuated from the area. The on-site emergency coordinator wilIinform the proper agencies in the event this is necessary. (Refer to Table 8.1)As called for in regulations developed under the Comprehensive Environmental ResponseCompensation Liability Act of 1980 (Super-fund), OHM’s practice is to report a spill of apound or more of any hazardous material for which a reportable quantity has not beenestablished and which is listed under the Solid Waste Disposal Act, Clean Air Act, CleanWater Act, or TSCA. OHM also follows the same practice for any substances not listed in theActs noted above but which can be classified as a hazardous waste under RCRA.Clean up personnel will take the following measures:lMake sure all unnecessary persons are removed from the hazard area.lPut on protective clothing and equipment.lIf a flammable material is involved, remove all ignition sources, and use spark andexplosion proof equipment for recovery of material.lRemove all surrounding materials that could be especially reactive with materials in thewaste. Determine the major components in the waste at the time of the spill.lIf wastes reach a storm sewer, try to dam the outfall by using sand, earth, sandbags,etc. If this is done, pump this material out into a temporary holding tank or drums assoon as possible.OHM Project 16487SSHSP Health and Safay Plan July 1995Infoormation herein is pmprietary and confidential and to bc used or released to others only with explicit writtq permission of OHM RemediationServices Corp.8-11
