Nl.� .w <br /> Dichlorodiphenyldichloroethylene <br /> DDE is a white crystalline solid used as an insecticide. Human systemic effects of <br /> exposure to DDE include eye, skin, and respiratory irritation,nausea or vomiting, and <br /> headache. DDE targets the liver and reproductive organs. DDE is listed as a probable <br /> human carcinogen. There are currently no CAL- or FED-OSHA PELs for DDE. <br /> Toxaphene <br /> Toxaphene is used as an insecticide and pesticide. Human systemic effects of exposure <br /> to toxaphene include eye, skin and respiratory irritation. Toxaphene targets the liver, <br /> respiratory system and reproductive system. The current CAL-OSHA PEL for toxaphene <br /> is 0.5 mg/m3. <br /> PHYSICAL HAZARDS <br /> Physical hazards associated with on site activities include slips,trips, falls, contact and <br /> crushing-type injuries,eye abrasions, contusions, lacerations, flammability and heat- <br /> stress concerns. The potential for such hazards necessitates the use of gloves and safety <br /> boots that meet American National Standards Institute (ANSI)Z41.1,eye protection <br /> meets ANSI Z87.1,and hard hats that meet ANSI Z89.1. Personnel engaged in strenuous <br /> physical labor are to wear sturdy work gloves. <br /> Additionally, experience indicates the noise level during use of a backhoe and other <br /> heavy equipment may exceed the CAL-OSHA action level of 85 dBA(decibels on A- <br /> weighted scale). Therefore, all personnel working in the exclusion zone during use of <br /> this equipment shall wear hearing protection in the form of plugs and/or earmuffs. <br /> See Table 2 for a list of potential physical hazards that may be present and the procedures <br /> that will be used to minimize these potential hazards. <br /> Use of Equipment <br /> Any equipment, including earth-moving equipment, drill rigs,cranes, or other heavy <br /> machinery, will be operated in strict compliance with the manufacturer's instructions, <br /> specifications, and limitations, as well as any applicable regulations. <br /> Any equipment or machinery that cannot be operated safely will be tagged and will not <br /> be operated until the unsafe condition has been removed or repaired. All repaired <br /> equipment will remain out of service until a designated qualified person has tested and <br /> inspected the equipment. <br /> The heavy equipment operator will clearly designate the zone(s)associated with each <br /> piece of heavy equipment where the potential for injuring workers exists.
