SafetyQuestion 376 of 1632

A crew encounters a buried drum of unknown liquid material while excavating. The safest course of action is to:

a.Stop work, restrict access, and have it identified
b.Photograph it, and continue working around it
c.Move it to the laydown yard for later disposal
d.Sample the contents, using gloves and a respirator

Explanation

An unknown buried container is treated as hazardous until it is shown not to be: stop work in the area, keep people out, and have qualified personnel identify the contents. Section 1541(g)(1) already requires the atmosphere to be tested before employees enter an excavation more than four feet deep where a hazardous atmosphere could reasonably be expected, and a buried drum is exactly that kind of reason. Each wrong answer moves something before anyone knows what the contents are. Photographing it and carrying on (b) leaves the crew exposed and risks puncturing the shell with a bucket. Moving it (c) can breach a corroded drum and makes the contractor a transporter of unidentified waste. And sampling it (d) presumes the protection needed: the right cartridge cannot be chosen for an unknown vapour, and gloves are selected by chemical.

Law Reference: 8 CCR §1541(g)(1); §5194(b); §5192
