c. A certificate must be filled out prior to entry stating the hazards have either been controlled or
eliminated
d. The entry must follow procedures documented on a completed permit
a. The hazard making it a PRCS must be non-atmospheric and must be eliminated prior to entry
Which one of the following statements is a requirement of both General Industry and Construction PRCS standards?
a. Employers must document that they have conducted the initial evaluation of their workplace to determine if any spaces are PRCS
b. If employers decide that their employees will enter permit spaces, they shall develop and implement a written permit space program
c. Employers need not comply with any part of the standards if they have identified the permit spaces and have taken effective measures to prevent their employees from entering those spaces

c. Identify hazards and have authority to correct the hazards
d. Demonstrate subject matter expertise and problem solving ability on PRCS issues
c. Identify hazards and have authority to correct the hazards
Which of the following statements is incorrect?
a. Once all the hazards associated with a permit space are eliminated, it may be reclassified as a non-permit space
b. Once a hazard is reintroduced into a space that has been reclassified from a permit space to a non-permit space, the reclassified space again becomes a permit space
c. Providing ventilation to keep air contaminants below the PEL is considered to be elimination of the hazard
d. A hazard is eliminated if no ongoing measures are required to keep the space hazard-free
c. Providing ventilation to keep air contaminants below the PEL is considered to be elimination of the hazard

a. Verify that the means of summoning rescue personnel are operable
b. Monitor activities inside and outside of the space to maintain safe entry conditions

Both General Industry and Construction PRCS standards require initial training of all employees
whose work is regulated by the standards. According to OSHA, additional training also is required:
a. On an annual basis thereafter
b. When the employer believes that the employee’s PRCS knowledge is inadequate
c. After a change in assigned duties within the employer’s PRCS program
d. After a near miss or fatality occurs during a confined space entry
b. When the employer believes that the employee’s PRCS knowledge is inadequate
An employer attempts to eliminate an engulfment hazard (3-foot deep sediment water) in a 20-foot deep open top tank that is currently classified as a PRCS. (The tank is only filled manually with a hose, no piped supply lines). Engulfment is the only hazard in the space. The tank is drained by opening a drainage valve from outside the tank. In order to verify that the engulfment hazard has been eliminated, and that no new hazards (e.g. slips) are present, a worker must enter to visually inspect the tank. Such an entry:
a. May be performed as a reclassification entry, all hazards are eliminated
b. Must be performed as a full permit entry, hazard abatement not yet verified
c. May be performed as an alternate procedures entry, with signed certification
d. Requires no permit, no certification, and no special procedures, since there are no hazards at the time of entry
b. Must be performed as a full permit entry, hazard abatement not yet verified
If the only hazard in a confined space is airborne asbestos fibers what should the space be classified as?
a. Non-permit confined space
b. Permit-required
c. Non-permit under alternate procedures
d. Non-permit under reclassification
a. Non-permit confined space

c. Barriers and shields
d. Engulfment monitoring system
d. Engulfment monitoring system
