HAZWOPER 40 -Lesson 13: Confined Spaces Questions
With All Correct Answers
Lesson Description correct answer -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: correct answer -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 correct answer -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.
,Lesson Focus

Cave-ins and Protective Support Systems
Safety Precautions
Installation and Removal of Protective Systems
Prior to Entering a Confined Space correct answer -Before entering a
confined space, a review of the specific guidelines for appropriate safe entry
and emergency exit is vital. Actual entry into a confined space should only be
allowed after the following has taken place:
All entrants and attendants have received proper training and equipment.
The designated authority on-site has issued the proper permit.
The appropriate PPE is in place and utilized.
OSHA's required procedures have been put into effect, especially the "buddy
system.
The procedures set forth in the following sections are based on OSHA
Standard in 29 CFR 1910.146. They are a means of protecting worker health
, and of avoiding accidental injury and death associated with entering, working
in, and exiting confined spaces. They are designed to make the confined space
safe, to make workers aware of related hazards, and to train in safe work
practices.
A preliminary evaluation of the site's characteristics must be performed prior
to site entry. A secondary more detailed evaluation must be conducted to
further identify existing hazards to aid in the selection of appropriate
engineering controls and personal protective equipment (PPE) for future site
activities. The evaluation must include all suspected conditions that are
immediately dangerous to life or health (IDLH) or that may cause serious
harm to employees (e.g., confined space entry, potentially explosive or
flammable situations, visible vapor clouds, etc.).
Permit-Required Confined Space Entry correct answer -As the name
implies, a work permit is required prior to entering a permit space. Common
types of spaces that would require permits include storage tanks, process
vessels, silos, vaults, storage bins, hoppers, ship compartments, exhaust ducts,
sewers, tunnels, and boilers. A space does not have to be enclosed to be
considered a permit-required confined space. Pits, trenches, and open-topped
vats also fit the OSHA description since they may have limited means of entry
and exit, and are not intended for habitation, and could possess hazardous
atmospheres.
OSHA has determined that individuals who enter permit-required confined
spaces are at a significant risk of death or injury. Therefore, all permit-
required confined spaces are to be considered dangerous until proven
otherwise
Permit System correct answer -To ensure the safety of the individual
entering the confined space, the permit system has been devised. In reality,
the permit is a mandatory checklist of the precautionary measures that need
to be taken before entry.
It is mandatory that an employer implement a functional permit program if a
permit-required confined space is on the premises. Before entry is authorized,
the employer must document:
