Loto incident


Die-setter injury may still result from the sudden dropping of the upper die shoe when freed from the slide (due to poke generator online incomplete or inadequate shoe attachment to the slide) if an energized inch control is activated (e.g., due to human error; by dropping a part.
However, you question whether extra time required to isolate energy during die-changes yields greater worker safety.
) that the Control of hazardous energy (lockout/tagout) standard is not intended to replace other existing standard provisions for loto.Kincaid: Thank you for your December 1, 2004, letter to the Occupational Safety and Health Administration's (osha's) Directorate of Enforcement Programs.To keep apprised of such developments, you may consult osha's website at http www.Make it home safe every day.We hope you find this information helpful.This 1979 osha Instruction describes die-setting methods that safely position the slide utilizing point-of-operation safeguarding techniques; however, this directive does not detail the energy control ( loto ) requirements for other hazardous aspects involved in the die-setting procedure.Back to text 5 In order to further clarify this mechanical power press die-setter instruction, our directorate will up-date this osha Instruction (STD 1-12.24) and the Control of hazardous energy, STD 1-7.3-1990, directive to specifically address power press die-setting procedures and the applicable hazardous energy.Wednesday at World Media Group located at 6737.For example, the use of the inch mode on a particular manufacture's hydraulic power press may by-pass critical safety systems (e.g., safety interlocks, presence sensing devices) creating a false sense of employee security in the event the die-setter(s) incorrectly relies on the inch device for.
4 Prior to placing hands or other body parts in a potentially hazardous machine area (e.g., to install, remove, adjust, clean, or repair dies loto must be used to protect employees from hazardous motion of the slide and other related energy hazards.
With respect to your contention that the removal and re-installation of lockout devices may create more opportunities for error, osha has determined that, when an employer follows the procedure established in 1910.147(f 1 testing and positioning activities can be performed without significant risk to employees.
The loto standard specifically excludes such control circuits as Energy isolating devices, see 1910.147(b).
Accordingly, you indicated that you are advising clients to keep their machines locked-out except for the limited portions of the die-setting operation that requires temporary energization.This includes Master Lock safety padlocks and lockout devices as well as custom key systems that ensure one employees key cannot open another employee's personal padlock.Securing the machine in inch mode can be accomplished easily by using a key-switch to select the operating modes.However, Setting up activities, by definition, involve work that prepares a press to perform its intended normal production operation; therefore, this exception generally would not apply to hydraulic and mechanical power press die-setting because the servicing activity is not taking place poker glossary during NPOs.Although the chance for human error does exist, the success of an employer's program depends upon a commitment to the energy control program through, in part, the development and implementation of: Procedures to clearly and specifically outline the necessary energy control steps to be taken.This type of incident truly isn't unique.In a police report, the victim has been identified as 41-year-old Hugo Ramirez-Arreola.Reply: No, the use of a safety device, such as an inch mechanism, does not adequately control all hazardous energy exposures to die-setters when their body parts are in, on, or in close proximity to machines or equipment danger zone areas.In order to effectively and comprehensively address hazardous energy control situations, including those associated with mechanical power press die-setting operations, osha specifically addressed the supplemental nature of the loto standard, with respect to other standards containing Part 1910 loto provisions.g., use of blocks.5 Your contention that this directive permits dies to be changed in part-revolution mechanical power presses without locking out, as long as the machine is safely in the inch mode, is inaccurate.Question 1: Does the lockout/tagout lOTO ) standard require that machines, including hydraulic presses, be de-energized and locked out except for the portion of die-setting that involves testing and positioning?For example, the following hazardous situations, which are not all inclusive, can result when employees set or remove dies: Uncontrolled potential mechanical energy may be present due to the ram/slide position and associated gravitational force causing the sudden release of stored energy causing hazardous motion;.Question 2: Assuming that all other required safety provisions such as operator training, control reliability, etc.The use of an inch safety device, for example, provides employee protection during the press's operating cycle pursuant to the 1910.212(a 3 ii) point-of-operation guarding requirements.
