LIUNA Training and Education Fund | Evaluated Learning Experience
Permit-Required Confined Space PRCS
LIUNA Pomfret, CT, and other LIUNA approved training centers
April 2011 – Present.
Upon successful completion of the course, students will be able to: describe at least three characteristics of a confined space; identify two factors that lead to fatal injuries in confined spaces; describe the four characteristics of a permit-required confined space; define and describe the three types of atmospheric hazards found in confined spaces; list the five types of airborne hazards; list and describe the six types of physical hazards found in confined spaces; list the four types of health effects from toxic chemicals; list three routes of entry for chemicals to enter the body; define and describe warning signs of acute and chronic exposure to toxic chemicals; list and describe the four types of heat stress; describe ways to prevent heat stress; explain and compare the differences, advantages, and disadvantages of direct-reading instruments (DRIs) versus laboratory analysis of workplace samples; identify two situations where atmospheric monitoring would typically be required during confined space entry operations; given the proper equipment, conduct the required workplace monitoring for permit-required confined space entry; given various sample chemicals and the proper equipment, demonstrate the use and interpret the readings of colorimetric detector tubes and a multi-gas meter; list and explain the appropriate responses if a personal monitoring device or sampling pump fails; list the components of a permit-required confined space entry program; explain the purposes of an entry permit; list at least five of the 15 required elements of an entry permit; list the required elements of pre-entry atmospheric testing; identify the members of a confined space entry team and describe the duties of each; describe at least two instances when training is required for confined space entry; define ventilation; list and describe at least three problems associated with ventilating a confined space; list at least four controllable atmospheric hazards and the methods to control them; explain supply and exhaust ventilation; explain the advantages and disadvantages of each; list at least five planning considerations to be given when ventilating confined spaces and explain why each is important; given a mock confined space, ventilation blower and manufacturers purge chart, calculate the amount of time to ventilate the confined space; evaluate a mock confined space for atmospheric hazards; plan and set up ventilation to remove hazards from the space in the time specified on a purge chart; define the following terms: affected employee, authorized employee, energy isolating device, energy source, lockout, lockout device, tagout, tagout device; identify the four categories of hazardous energy and the means for controlling each; define the roles of affected and authorized employees when working under an energy control program; given a scenario, identify potential sources of hazardous energy and a method for controlling each; explain the terms “assigned protection factor” (APF) and “maximum use concentration”; explain the differences between an air-purifying respirator (APR) and an atmosphere-supplying respirator; describe three types of APRs and give the APF for each; list and explain at least six limitations of APRs; list and explain the three filter series and three filter-efficiency levels for particulate filters; explain the terms “breakthrough” and “warning properties” and list four steps that should be taken if breakthrough occurs; explain the differences among three breathing air delivery systems for breathing air: continuous flow, demand, and pressure demand; explain how a supplied airline respirator (SAR) works; list three limitations of the SAR and the APFs for both the SAR and the SAR with escape; explain how a self-contained breathing apparatus (SCBA) works, its limitations, and APF; explain the difference between a qualitative and a quantitative fit test, and give two examples of each; demonstrate the proper procedures for inspecting and donning a full-face APR; explain and demonstrate the proper procedure for performing a positive and negative user seal check on an APR; demonstrate the proper procedure for inspecting and donning an SCBA.
Major topics include: hazard recognition, atmospheric monitoring, entry plans policy and procedures, personal protective equipment (PPE), and hazard mitigation. The course is designed to provide students with the knowledge and skills associated with working in and around confined spaces.
In the lower division baccalaureate /associate degree category, 1 semester hour in Construction Safety (4/16).
