Health&Safety Plan �..i Page 3 of 17 Certified 40 Hour OSHA,29 CFR 1910. 120 Hazardous Waste Operations: Bryan Musca Duarte Silva 2.0 RISK ANALYSIS This section assesses the chemical and physical hazards that are known to exist at the site and those that may be created by the remediation efforts. Table 2 summarizes the hazards associated with each of these tasks. The hazard analysis has been divided into three critical areas: • Exposure: Expected frequency of exposure to a hazard; • Probability: Likelihood of an injury upon exposure to a hazard; • Consequence: Probable degree of injury or effect an injury will have on the effectiveness of a team member. An explanation of the letters denoting the degrees of exposure,and consequence is provided at the end of the table. Contaminants most likely to become encountered during field operations at the site are the Petroleum Hydrocarbons and Metals listed in Table 1. A list of the occupational exposure limits and signs and symptoms of exposure is also listed in Table 1. Most work required in this project might potentially expose personnel to materials that may contain any or all of these contaminants.Any personnel entering the site shall be informed of all hazards associated with these contaminants. The physical hazards expected to be present during site investigation activities include: • Saw Cutting • Snapping Cables,Slings and Rope • Drilling Equipment • Moving Equipment • Heavy Equipment • Sharp Objects • Loose Foundations • Open Pits or Ditches • Excessive Noise • Fire/Explosions • Buried Utility Lines • Energized Overhead and Underground Power Lines • Heat Stress 3.0 PROCEDURES TO MITIGATE HAZARDS This section describes those procedures to be followed in order to ensure the avoidance of operational hazards, as discussed previously. These hazards include mechanical, electrical, chemical, acoustical, biological, and temperature hazards.Those hazards associated with confined spaces are not anticipated to occur,and are not discussed. 3.1 Mechanical Hazards The following procedures shall be followed during all phases of the operation to reduce those risks associated with mechanical equipment: • Stay well clear of drill rods and augers while they are rotating and being hoisted. Extreme care is to be exercised when steel cables are being used to lift the drilling apparatus from the ground. • Stand clear of the operating circle of excavators,backhoes,etc. • Equipment maintenance schedules are the responsibility of each individual contractor. Equipment is to be checked daily. Any equipment deemed by a Musco Excavators, Inc. employee to be in an unsafe state of repairs, or operated in an unsafe manner shall be shut down until corrective action is taken. Equipment
