HAZWOPER 40 -Lesson 13: Confined Spaces Already Graded A Lesson Description This lesson, Confined Spaces, focuses on OSHA Standard 29 CFR 1910.146, which regulates what the employer must do to make confined space entry work safe for workers. This lesson addresses both the employer's and the employee's confined space responsibilities. It reviews the types of hazards (i.e., soil, atmosphere, and gas) that must be identified and controlled. Specific details are provided pertaining to the use of proper engineering controls like positive- and negative-pressure ventilation systems, as well as the selection and use of PPE (such as appropriate respirators and body harness systems). Among the many issues addressed, the discussion of pre-entry training, rescue team responsibilities, and ensuring that all permit procedures are followed is of primary importance. Learning Objectives At the completion of this lesson, you will be able to: List OSHA guidelines for what should be documented on an entry permit. Name three main atmospheric hazards that cause concern in confined spaces. Discuss the two types of forced ventilation. Describe the two most common causes of asphyxia. Identify concerns associated with lacerations. Introduction The possibility of the occurrence of confined spaces at hazardous waste sites should not be overlooked. Entering a confined space can be deadly. It is important to recognize confined spaces and to distinguish confined spaces from permit-required confined spaces. Employees must be made aware of the existence of confined spaces at hazardous waste sites. NOTE: All individuals involved in confined space entry are required to have appropriate levels of confined space entry training.
