The three major OSHA standards most frequently cited to employers regarding contractor safety are Process Safety Management of Highly Hazardous Chemical (29 CFR 1910.110), Control of Hazardous Energy (Lockout/Tagout) (29 CFR 1910.147), and Hazard Communication Standard (29 CFR 1910.1200). These regulations pertain to the hiring of outside contractors and subcontractors to perform repair work, plant modification, equipment maintenance, etc. Many countries around the world have their comparable standards.

OSHA s 29 CFR 1910.147 states that employers are required to develop, document, and utilize an energy control procedures program to control potentially hazardous energy. The energy control procedures must specifically outline the scope, purpose, authorization, rules, and techniques to be utilized for the control of hazardous energy and the means to enforce compliance including, but not limited to, the following ... 

In Appendix A of 29 CFR 1910.1450, OSHA recommends inclusion of a section on protective apparel and equipment in any chemical safety plan. This might be handled in other portions of the plan, but this section could be a place to incorporate a formal analysis for the required personal protective equipment (PPE). The formal analysis could be handled in the same format as the job hazard analysis. Instead of critical steps for job duties, chemical and energy sources could be identified, along with the protection needs and requirements, and then the list of specific PPE to mitigate the hazard. 

The Occupational Safety and Health Administration (OSHA) regulates lockout/tagout through the Control of Hazardous Energy standard, found at 29 CFR 1910.147. This standard mandates training, audits, and recordkeeping to ensure that workers will not be in-jvu ed by unintentionally energized equipment. 

Thank you for your March 9, 2006, letter to the Occupational Safety and Health Administration s (OSHA) Directorate of Enforcement Programs. You stated that you represent a company in the baking industry with production facilities in different states and have questions regarding Federal OSHA s Control of hazardous energy (lockout/tagout or LOTOjand Bakery equipment standards, 29 CFR 1910.147 and 1910.263, respectively. Your scenarios, paraphrased questions and our replies follow. 

Reply The adjustment of a machine component s timing mechanisms constitutes machine servicing activity, which is covered by the LOTO standard if an employee(s) is exposed to hazardous energy. See 1910.147(a)(2)(ii)(A) and (B). As described in the previous reply, there is an exception for minor servicing activities which take place during normal production operations, provided that the work is performed using alternative measures which provide effective protection. See the 29 CFR 1910.147(a)(2)(ii) note.
