MACHINERY AND EQUIPMENT – DE-ENERGIZING OR PROVIDING EXTENSION TOOLS BEFORE CLEANING Cal. Code Regs, tit. 8, § 3314(c)(1) (2014) – While Employer’s method of cleaning a flanging machine without use of an extension tool may have been appropriate with proper training, it failed to demonstrate that it provided employees with “thorough training” in the alternative method. The Board reversed the ALJ’s dismissal of the citation.
