SMONFOUR Site Nazard Analysis <br /> The hazards associated with the activities described in this section have been separated into three groups: <br /> physical, chemical, and biological.The characteristics of each of these groups and potential employee <br /> exposure to these hazards as they relate to the field investigation activities are discussed in this section. <br /> URS has a Health and Safety Management System(Appendix A)that was developed to provide a safe <br /> work environment for employees,meet client health and safety requirements,comply with occupational <br /> health and safety regulations,and to minimize injury related liability. This HASP is augmented by the <br /> URS Health and Safety Program's relevant Safety Management Standards (SMSs)that were developed <br /> ' under the Health and Safety Management System and are required to be available on-site during all <br /> activities. <br /> 4.1 PHYSICAL HAZARDS <br /> Project physical hazards include potential for accidents or physical injury(e.g.,heat/cold stress); exposure <br /> to excessive noise levels; machinery and mechanized equipment(e.g.,pumps,trucks,loaders,hand and <br /> power tools)hazards; elevated work platforms (e.g.,ladders); aboveground utilities; slip-trip-fall hazards; <br /> and,muscle strains. These hazards are discussed further in the following paragraphs.The SSO will ensure <br /> that safe work practices are followed at the project work site(s)and make any changes necessary to ensure <br /> the safety of the public, and site personnel.The project field personnel are required to be fully informed <br /> of these hazards,to implement appropriate safety precautions,and to follow prescribed safety procedures <br /> and protocol. The project field personnel will have access to all the Safety Management Standard(SMSs) <br /> identified in this HASP.The typical physical hazards anticipated present on this site,and the methods for <br /> preventing injury due to these hazards are described below. <br /> Hazards from confined space entry and poor illumination(night work)are not anticipated to be <br /> encountered on site and so are not addressed in this HASP. <br /> 4.1.1 Temperature Extremes (SMS 018) <br /> Heat Stress <br /> Personnel will be monitored and the work schedule adjusted as necessary during periods of elevated <br /> ambient temperatures above 85°F or humidity greater than 50%.Activities requiring strenuous labor will, <br /> whenever feasible,be scheduled during morning hours during hot weather.To control heat stress, <br /> personnel will follow the specific heat-related health and safety procedures described in SMS 018 (Heat <br /> Stress). <br /> Working in elevated temperatures while wearing impermeable PPE may lead to heat stress in the form of <br /> heat exhaustion and/or heat stroke. Symptoms of heat exhaustion include dizziness,light-headedness, <br /> nausea,slurred speech,fatigue,copious perspiration, cool clammy skin,and an increased resting heart <br /> rate (I 10 beats per minute). Symptoms of heat stroke include delirium,fainting,and hot,dry,flushed <br /> IT 1 -N V-11\\4-1 <br /> H:\WPROCESS\25532\WORLDENTERPRISE\WELL DESTRUCTIONWTTACHMENT C WORLD ENTERPRISES HSP TG ED S.DOC\8 O <br />
