SafetyQuestion 93 of 100
What is required before a worker enters a permit-required confined space, such as a tank being coated?
a.Atmospheric testing, ventilation, and a permit/entry procedure with an attendant
b.Only a flashlight
c.Nothing special is needed
d.Just a quick look inside
Explanation
Permit-required confined spaces can contain toxic or oxygen-deficient atmospheres, especially when solvent coatings are applied, so Cal/OSHA requires air monitoring, ventilation, a written permit, and an attendant outside. Entry without these controls has caused fatalities. A rescue plan must also be in place before entry.
