Valves
The leak definition of a valve
What is 500ppm VOC?
The leak definition of a pump
What is 1,000ppm VOC?
The mixing of different refinery products to make petroleum fuels
Most common injury that can be mitigated by wearing proper PPE such as Kevlar sleeves
What are burns?
VOC
What is a volatile organic compound?
The number of passing readings a valve needs for it's leaker tag to be removed
What is 3 passing readings?
The amount of passing readings a pump needs to have to have it's leaker tag removed
What is 1 passing reading?
Breaks down large, heavy hydrocarbons from crude oil into smaller, lighter products using heat, pressure, and catalysts
What is cracking?
Gas that is heavier than air and is odorless at high concentrations
What is H2S?
AVO
A valve with it's handle in line with the direction of flow or it's stem is fully exposed to allow passage of process
What is an open valve?
Allows passage of process in one direction and prevent backflow to protect pumps and equipment, maintaining pressure and efficiency
What is the purpose of a check valve?
Molecular structure of low-quality gasoline is rearranged to improve combustion characteristics
What is reforming?
Historically used for insulation and poses long-term health risks such as mesothelioma
What is asbestos?
DOR
What is delay of repair?
The size and type of valves techs are allowed to do repairs on
What are gate/globe valves 8in and under?
Part of a pump with rotating parts. If not careful could lead to entanglement
What is a pump seal?
Separates process by boiling point into gasoline, naptha, kerosene, diesel, and heavy oil.
Anything that can provide enough energy to start a fire/explosion such as welding sparks, electrical equipment, internal combustion engines, and open flame
What is an ignition source?
Conditions such as rusty packing, uneven packing, built up process, high-risk area, and no-first attempt areas, valve over 8 in.
What are conditions that would cause you to skip tightening valve packing?
Pump that has two actuating bladders to generate flow
What is a diaphragm pump?
Produces cleaner gasoline by removing contaminates like sulfur with catalysts
What is treating?
Known carcinogen that is found naturally in crude oil and emitted during refining
What is benzene?
MOC
what is management of change?
