30
T/F - The CSE supervisor and authorized entrant can be the same person.
True
When employees are working in a PRCS, how often should the atmosphere be monitored
Continuously as long as entrants are in the space
What safety procedure can be performed to eliminate exposure to live electrical parts in a confined space
LOTO
When is ok to hook a rope to an entrant to manually pull them out without a tripod or fixed point pulley
Never
This is the Number 1 cause of death in confined spaces
Asphyxiation or low oxygen
This is how long canceled/closed CSE Permits are required to be kept in the employer's file.
1-year
Four criteria that make a confined space a PRCS are:
1. Contains or has potential for hazardous atmosphere
2. Contains material that is an engulfment hazard
3. Has an internal configuration that could trap EE
4. ?
Contains any other recognized serious safety or health hazard (i.e. exposed live electrical parts, unguarded moving machinery, steam/temp, etc)
To prevent liquids from entering our confined space thru a pipe, we can plug the pipe, insert a blank between flanges, shut off and LOTO an upstream valve or ___________________
Disconnect the pipe from the CSE
What is the purpose of bump testing an air monitor before first use in a shift
To exercise the sensors and verify alarms
