Operator shelters

Similar undocumented stories have been shared at inter-plant safety meetings. There was a story about an individual in a small enclosed operators shelter who became suspicious about his surroundings when his cigarette would not stay lit. Some months before, an... 

The pre-op crew steamed out the B Unit first and vented it through the 8-inch steam vent piping. The failure occurred about four days later. An eyewitness in the operators shelter heard what sounded like a muffled explosion and ran out the back door to see if he could locate fire or smoke. Fortunately, no fire could be seen, but the collapsed coke drum was very visible. 

Apart from building that house equipment (e.g., compressor houses), it is often necessary to position control houses, substations, analyzer houses, and operator shelters within the process unit battery limits. Administration buildings and warehouses are generally located away from process unit areas. Control houses and substations are usually located at the edge of the unit adjacent to a plant road, 50 ft (15,000 mm) from the operating equipment. As seen in Exhibit 3-24, analyzer houses and operator shelters should be located next to the equipment that they service. 

Operator shelters should be located at least 15 meters from the nearest process-unit equipment containing flammable liquids or vapors and 15 meters from fired heaters. 

Landfill-operation plan. The layout of the site and the development of a workable operating schedule are the main features of a landfill-operation plan. In planning the layout of a landfill site, the location of the following must be determined (1) access roads (2) equipment shelters (3) scales, if used (4) storage sites for special wastes (5) topsoil-stockpile sites (6) landfill areas and (7) plantings. 

The compressor or blower installation in a typical refinery or chemical process unit is not out-of-doors completely. Some form of shelter often is provided, ranging from only a roof to a completely closed building. When process equipment such as a centrifugal gas compressor, which is not hazardous in normal operation, is present in the shelter, the hazard classification depends on the extent to that which the shelter restricts ventilation. The extent of the shelter provided determines the area classification and the type of motor enclosure that should be applied. 

It is generally agreed that a shelter with a roof having ridge ventilation and with curtain walls not extending lower than 8 feet above the operating platform would be freely ventilated. Because a gas compressor would not be a source of hazard, except under abnormal conditions such as an equipment failure, this type of compressor shelter is usually classified as a Division 2 area.

A fire-resistant building is located in the facility, 75 ft (23 m) from the nearest tank, and 25 ft (7.5 m) from the nearest edge of the dike wall. The building contains tank field monitoring and control equipment, provides shelter to the operators, and also houses administrative support activities. The building is equipped with multiple means of egress. 

Strength Rescue, curfew and evacuation operations were initially planned for a 7-day period. Issues identified and addressed included food/hydration/shelter/sanitation bar-ricades/shift rotation. ADPS and ACSO provided hurricane stock of bottled water for responders. 

Improvement Item EOC did not have press releases prior to distribution at CP. Hard copies of press releases were not initially distributed at press conferences. Unmanned radio stations limited ability for local alerts to be made. Initial notification did not go out through NOAA Weather Radio, although it was utilized later in the day. EOC (Emergency Operation Center) PIO (Public Information Officer) could not get response from PIOs at CP (Command Post) to coordinate messages for media at EOC. Citizens in shelters had no official information source. 

This should provide direction as to how operations staff, emergency responders, and the public should respond to a potential toxic release (e.g., chemical plumes released), including facility evacuation, personnel accountability, proper personal protective equipment (PPE) as dictated by the Risk Management Program and Process Safety Management Plan, and whether the nearby public should be in-place sheltered or evacuated. 

Functional drill The purpose of a functional drill is to test an individual component of the emergency response plan. The drill could test the communication system, emergency operations center, evacuation, or the shelter-in-place plan. 12 months... 

Shelters for the workers should be set up in the vicinity of each building. These are huts covered with earth at the side of the operating building. If the buildings have three stout walls the shelter may be located behind one of them. Doors and windows should be large to give plenty of light, and closed from outside with a wooden... 

A fast chemical sensor that operates at a reduced pressure of 50 torr (6700 Pa) and with a flow of 1 standard liter per minute must be maintained in an instrument shelter. Considerations of flow distortion require that 10 m separate the sensor from its intake on the tower near the sonic anemometer. Three ducting arrangements can be considered. The first would involve drawing air along 10 m of 1/4-inch tubing (0.2 cm internal radius) and controlling the flow and pressure at the sensor itself. The second option would place the pressure-flow controller at the inlet and allow the inlet intake to flow at the reduced pressure. The third course would be to use a...
