OSHA has cited a container cleaning business for exposing employees to confined space hazards after two employees were fatally overcome by fumes while cleaning a tank trailer. The company faces $497,920 in penalties. OSHA investigators determined that one employee became unresponsive after entering the trailer’s confined space.
