COURSE 503: EM385-1-1 Safety & Health - Sections 20-26

Safety guides and audits to make your job as a safety professional easier

Welcome!

Welcome to the course. This is the fourth course in the 40-Hour EM385-1-1 Construction Safety Hazard Awareness Course for Contractors series and is designed to help you understand EM 385-1-1, Safety and Health Requirements, Sections 20-26. Note: Completion of courses 500-504 is equivalent to the 40-Hour Construction Safety Hazard Awareness for Contractors Course.

The purpose of the training is to enhance the awareness of proposed and alternate Site Safety & Health Officers (SSHOs) performing awarded construction, service, and environmental contract work, and to provide all contractor on-site personnel an opportunity to obtain adequate knowledge to assess unsafe worksite conditions.

This course is designed primarily for contractors who work with federal government projects, but may be helpful for anyone. This basic training is designed to help those with little or no prior safety and health training.

Here's how it works:

  1. Study each course module. To start, click on the course "Modules" tab above. On average, it takes about 30 minutes to one hour to complete each module. The entire course will take about 40 Hours to read the material, answer quiz questions, and complete the final exam. The best strategy is to take your time and make sure you understand the course material.

  2. Answer the study questions. You can find the study questions within the "Study Questions" tab above or at the end of each study guide. Print the questions so that you can hunt for the answers as you read through the material.

  3. Complete and submit the course FINAL EXAM.

    • Final exams consist of 30 questions taken from the course.
    • The exam is OPEN BOOK. You can use your notes or the study guide to help answer questions you are unsure of.
    • You must pass the final exam with at least an 80% score.
    • If you do not pass the exam, you may retake the exam.
    • If you pass the exam, you may not retake the exam just to raise your score.

Introduction

EM 385-1-1, USACE SAFETY AND HEALTH REQUIREMENTS

EM385-1-1 prescribes the safety and health requirements for all Corps of Engineers activities and operations. The "EM" in the manual's title means Engineers Manual.

The Department of Defense has mandated that EM385-1-1 Safety & Health Requirements be the "primary document" for the safety parameters on all construction projects. Contractors working at military bases must comply with the requirements of USACE EM-385-1-1. All managers, supervisors, contractors, or construction personnel working on military contracts and any worker needing to be compliant with EM 385-1-1 regulations and compliance standards.

The manual applies to Headquarters, US Army Corps of Engineers (HQUSACE) elements, major subordinate commands, districts, centers, laboratories, and field operating activities (FOA), as well as USACE contracts and those administered on behalf of USACE. Applicability extends to occupational exposure for missions under the command of the Chief of Engineers, whether accomplished by military, civilian, or contractor personnel.

The information in this course references EM 385-1-1, dated 30 November 2014.

Course Objectives

This course will cover the topics in Sections 20-26 and will inform and help you understand the following information related to each of these Sections:

  • Contractor responsibilities for designing, developing, and deploying an effective safety and health program that complies with the requirements of the US Army Corps of Engineers (USACE)

  • The required plans, programs, policies, processes, and procedures that help to ensure hazard free work on USACE facilities and projects.

  • The needed knowledge and skills to manage programs, recognize hazards, prevent accidents, inspect and enforce regulatory requirements.

  • Identify the skills required to identify, prevent, and correct potential and actual safety and health hazards on construction worksites.

  • The basic knowledge and skills needed to effectively review, analyze and evaluate contractor Accident Prevention Plans (APP) and Activity Hazard Analysis (AHA)

  • The Skills required to perform effective incident and accident mishap investigations, properly document the facts, and implement safety and health requirements of EM385-1-1.
