Oxygen Clean Worker
Course Overview
Course Introduction
The course begins with a brief presentation of the instructors experience working with oxygen systems, oxygen cleaning, and design of oxygen systems and components. The classroom atmosphere is casual and comfortable where questions about the subject matter are encouraged at any time during the class.
Historical Problems Associated With Oxygen Systems
The need for oxygen cleanliness is all about personnel and equipment safety. Examples are given of failures in Naval oxygen systems, on an international scale, that could have been avoided with better procedures and/or training.
Video regarding concerns and shipboard practices while working on oxygen systems
The US Navy has released a training video that shows some of the concerns with handling shipboard handling of oxygen components and systems during maintenance operations. The video is pertinent to all oxygen maintenance operations but especially if shipboard work is employed.
Why training is necessary
A brief discussion on why it is important to have a properly trained workforce when handling oxygen components.
Hydrocarbons
Examples of common hydrocarbons and how they can be inadvertently introduced into an oxygen system
Why we are concerned with hydrocarbons
Discussions on how insignificant amounts of hydrocarbon material can start an incident that results in catastrophic failure
How hydrocarbons are found
Methods of inspecting and testing for hydrocarbon contamination
Particulate
What constitutes particulate matter that is considered contamination?
Why we have to be concerned with particulate
A discussion of how particles in an oxygen system can result in fire or explosion.
How we test for particulate
Methods of finding particulate contamination
What is oxygen clean?
Oxygen clean is defined. It is stressed that a component or system cannot truly be considered clean unless there is traceable evidence of the cleaning process.
Materials for oxygen service
Suitable and non-suitable metallic and non-metallic materials for oxygen system design and maintenance.
Cleaning of Components
Methods of pre-cleaning, a discussion of methods, materials and chemicals.
Is rough cleaning required? Sometimes it is necessary to have three levels of cleaning.
Methods of final cleaning
Final cleaning methods materials and chemicals
Testing for cleanliness
NVR Analysis
Non Volatile Residue is the term used for non-particulate species left in the cleaning solution. The measurement of NVR is discussed.
Particulate Rinse
The methods of easy determination of rejectable and acceptable particulate matter after cleaning.
pH test
White light inspection
Methods and equipment
Black light inspection
Methods and equipment
Drying and Preservation
Drying and preservation of cleanliness is a requirement. This section discusses acceptable methods of drying and packaging.
Cleaning of Installed Oxygen Piping Systems
Cleaning installed ship’s systems require flushing rigs and have requirements differing from components cleaning. This section covers systems flushing, systems testing, systems rinse and drying and preservation
Garments for oxygen workers
What garments are required when working in a clean environment? There are minimum acceptable requirements.
Clean room entry procedures
What are the recognized procedures for entering the clean room in order to preserve the integrity of the area?
Prohibited materials
Discussions about the materials that should never be brought into a clean area. What the safeguards are if you must use a prohibited material.
Work methods and efficiency
Inefficiency can cause contamination in the clean area.
In-process packaging
Protecting in-process components during down times.
Long term packaging and labeling
Packaging and protecting for storage and shipout.
Clean room Maintenance
What is required to keep a clean room clean
Assembly procedure clean room
Work procedures when handling clean components in the clean room
Assembly procedures shop floor
Work procedures for oxygen clean systems
Storage considerations
Storage of oxygen clean parts in the stock room and work area.
Maintaining oxygen cleanliness during maintenance operations
What are the requirements and procedures for keeping systems and components clean during repair or maintenance operations
Length of course
For most companies and applications the training takes one and a half days. Some specialized applications could take longer. You will be asked about your work after your inquiry.
Cost basis
Costs for training is based on a fee of $850 per day flat rate for the group. This includes all training materials, and training certification at completion. Travel expenses are additional and will be quoted for your location.
