Text For Citation: 01 Item/Group: 001 Hazard: CONFINED

Section 5(a)(1): The employer did not furnish employment and a place of employment which were free from recognized hazards that were causing or likely to cause death or serious physical harm to employees in that employees were exposed to the hazards of oxygen deficiency, flammable and/or toxic atmospheres inside vessels such as but not limited to rotorells. a. On or about November 18, 1992, and at times prior thereto, employees were exposed to the hazards associated with improper confined space entry while cleaning, servicing and/or inspecting the interior of rotocell extractor #2 in building 26 of the Crude Oil Unit. Prior to entry, a confined space program had been developed, however procedures for confined space entry were not fully implemented or enforced and the confined space program was inadequate. ie: appropriate atmospheric testing and monitoring equipment had not been provided nor had employees been provided training in the irritations and proper use of such equipment, an effective method to summon rescuers was not accessible to the attendants proper atmospheric testing procedures were not followed when re-entering a previously vacated confined space, confined space entry permits were not adequately completed and adequate respiratory protection was not available to all employees participating in confined space entry. Among other methods, one feasible and acceptable abatement method to correct these hazards is to implement and enforce an adequate plant confined space entry program such as that stipulated by ANSI Z117.1-1989 American National Standard Institute Safety Requirements for Confined Spaces. Such a program shall include, as a minimum, the following elements: 1). Written procedures covering a permit system, ventilation, atmospheric testing, rescue procedures and employee training. 2). The completion and posting of a confined space entry permit which requires authorization and approval in writing that specifies the location and type of work to be done and certifies that all existing and potential hazards have been evaluated by a qualified person and that necessary measures have been taken to ensure the safety of each worker. 3). Blinding, blocking, bleeding, purging, lockout or any other steps necessary to reduce and to ensure zero mechanical and thermal state of all mechanical, electrical, hydraulic, pneumatic liquid and gas systems relating to the confined space that may create a hazard to employees during entry or while working in the confined space should any of these systems be put in motion or otherwise activated. A worker individual lock is to be applied and in unique situation tag shall be attached to the lock and energizing or activating controls or devices. 4). Mechanical ventilation of the confined space prior to entry and continued ventilation to provide a safe atmosphere, when determined neccessary as described in (2) above. 5). Testing the atmosphere of the confined space prior to entry and on a regular basis for presence of sufficient oxygen (19.5) and absence of hazardous levels of toxic or combustible gases or vapors, when determined necessary as described in (2) above. 6). Emergency rescue procedures with requirement that trained personnel are available and are stationed outside the confined space with proper equipment to provide for the rescue of persons entering the space as determined necessary and as described in (2) above. Such equipment must include safety harness and life lines with provisions for hoisting employees from the confined space. If entry is required for a rescue, the rescuing employee must be equipped with approved air supplied respiratory equipment and other appropriate personal protective equipment. 7). Training of any and all employees required to enter the confined spaces and all employees required to standby for rescue. This training shall include procedures required prior to entry, during occupation of the confined space, procedures for safe rescue of employees in the confined space and the hazards associated with work in confined spaces.
