You have a choice of “SIGN UP” as an individual or you can “JOIN TEAM” if you want to join an existing organization or person.


The majority of people and or companies will use this option. You can sign up as an individual or a company. You can create a specific company name or the APP will assign your name as the company. Each person / company is assigned a unique access code. A company which is first using this service will want to use generic company data – with one primary manager


If you work for a company or wish to share the data of an existing user, you will log in using this option. The company or primary user will provide you with their Team / Company Access Code (found in their user account). The individual will start with their name and an E-mail address. Keep in mind that if you work for a company and you might also want to have your own personal account, you will be required to use two different email addresses. The manager of the company account can delete access to any individual. A deleted person will still have access to their account but will not have access to the company or team group inspection data.

If you have a company e-mail address, we recommend that you use the company E-mail address to join the company / team

The system tracks and follows the individual via E-mails. It assigns a unique identifier to each user. Sometimes a USER will relate to a group and they also wish to have their own personal inspection account. The user will need to use two different email accounts to accomplish this goal.

  • Keep in mind that you cannot combine e-mail accounts.


Must contain one Capital letter at least six digits in total. A combination of letters numbers and symbols may be used.

  • When the E-mail verification is sent – double check your e-mail spam folder
  • PASSWORDS – Must contain a Capital letter


The person who creates the initial company account has control of the data and users. Anyone supplied with the access code will have their inspections added to the team account. We recommend that the person who sets up a company / group account uses a general E-mail account and creates a password which might be shared with key staff members. The administrator of the team account will have the ability to delete the users (swipe the user and hit delete). Anyone with company access will have the ability to review all the inspections

  • Create a unique company or team name


Go to the UPPER LEFT-HAND hash marks (hamburger) Your name will appear on the top – tap it to enter. Hit PROFILE. Under profile you have several options:


If you are setting up a personal account, you may want your name associated. This is an option. If you are setting up a company or group account, create a unique name.

  • You can go to your account and edit the name or information at anytime

Phone number

Enter the phone number if you would like to provide this information on the inspection form and to the customer. For a company we recommend the general information line.

License or inspector number

This is where you set up your inspector number. If you are setting up a team account, there is no reason to add a number. For the individual inspector you would want to identify yourself. This is optional and not a requirement. If you enter the data, it will auto populate on the inspection form.

  • There are no restriction on the license number. We do recommend that if you have been formerly trained in cylinder inspections, use the number provided by the training agency. If you are a hydrostatic requalifier you can use your RIN.

license expiration date

Many governments require that an inspector get re-certified on a regular basis. If your certification were to expire on a given date, enter it in this information. It states on the inspection form when your license expires and reminds you to refresh your inspector status.


Brings you back to the main page


Lists your customers based on inspections. Customers can be located more easily via the search bar on the top of the page. The search function can be used with just partial knowledge of the customer’s name or spelling.


Change Team name. The name of your company or team can be edited from this section. The name chosen will be auto populated in the inspection forms provided to the customer or database.

Contact number / E-mail for team

Choose a contact phone number generic to the company or team. If you chose and individual number, ad that person leaves the team you will need to remember to update the number. The same holds true for the E-mail. Attempt to use a INFO@ address or something others can access to keep in communication with the customer. The address entered populates the forms. It is optional.


The access code provided to the company/Team cannot be changed, it is assigned by the server. The server uses the E-mail address to identify the primary account holder and assigns the unique code.

If you want someone to join your team, and input inspection data for the company/team, provide them with the unique access code. When that member signs up they use the button titles “JOIN TEAM/ Company” Provide this to anyone you wish to join your team.


Users are members of your team / group. Anyone who has been provided the code and joins team will be listed in your user section. If a suspected user does not appear, they likely have not verified their account using the e-mail verification system.

Once the user has been added to your account the inspections they perform will be added to the team or company data base. The company or team retains control of the inspections.

If someone leaves the company/team their access can be deleted. The administrator of the team/company account simply SWIPES the name to the left and hits DELETE. That user can no longer access the data, but any inspections they perform will no longer be added to the database.


The ABOUT US section gives you numerous links to social pages and websites telling you about Cylinder Training Services. We try to post relevant content on all our sites or share pictures of unique cylinders or damage to cylinders.


Inspector Information - (page 1 / 12)

If you have set up your user account during the initial setup – this section should auto populate. It will include your name and your inspector number. If you have not set up your account, you must manually enter the data before moving forward.

Serial Number (page 2 / 12)

This is the section where you enter the serial number of the cylinder. Once a serial number has been entered it becomes searchable. During future inspections the system will recognize the cylinder and auto-populate permanent cylinder data such as material, government authority owner information, material and pressure ratings.

Select customer (page 3 / 12)

You have the choice of selecting a known customer (from a previous inspection) or adding new customer data to the cylinder. For a new customer, use NEW CUSTOMER from the drop-down list. If the system auto-populates a name you have ability to override that information with new customer information. The system uses a drop list to scroll through your known customers. Any updates you provide will be auto-populated in the future.

Cylinder Information (page 4 / 12)

The cylinder information page is where you enter the data of that cylinder, specified by the serial number you entered. In the future this information will auto-populate.


what material was used to create the cylinder? Steel, aluminum or composite. A drop-down list is created once a material has been entered. If the cylinder has been assigned a SP or exemption number, to denote its specific material, enter the number in this section.

Government approval

Which country governs the rules and use of the cylinder. List your country if it regulates the cylinders design specifications. A drop-down list is created, and new countries can be added.

Primary Reference Point

This term is taught in the Cylinder Training Services inspection courses. In case you want to monitor one specific location on a cylinder (tap stop mark, corrosion, crack???) all parties inspecting the cylinder in the future need to know a general vicinity or where the original inspector started their documentation. The inspector will tell others what permanent mark they use on a cylinder to designate as the primary point or the 12 O’clock position/top of the cylinder. The primary point should be something permanently marked on the cylinder such as the Initial hydro mark or government approval mark. They then use this point as a “0” heading or “0” degree mark. The inspector can then state “180” degrees OR 6 o’clock position from their primary mark to identify a specific area of the cylinder.

Service pressure

State the service pressure marked on the cylinder in either BAR or PSI.

Owner Identifying Marks

This is optional. If a user or company numbers their cylinders are has a specific name applied, the inspector can place that data in this area. It is NOT a mandatory marking. It is a marking applied by the individual user to conform to their facilities tracking protocols. It might be a number, letter or combination of both.


Drop down list of company which manufactured this specific cylinder. You can use a manufacturer name or the M# assigned to that manufacturer. Be cautious not to use a distributor name or mark.

Initial Hydro date (Page 5 / 12)

When was the cylinder first manufactured? When is its birthdate? The cylinder will be marked the month and year it was first manufactured.  The cylinder will be marked with the month and year, but not the actual day.

Last Hydro date

when was the most recent hydrostatic requalification date? This will be the date that lists the month and year, with the RIN in the center of the numbers. If you don’t know how to identify the RIN, we recommend taking the formal inspection class. The date is then entered using a scrolling month and year – no date.

Within Hydro

Inspect the cylinder and determine if the cylinder is current with its hydrostatic test period. If you check YES, the system will display the forward area, indicating to proceed with the inspection.

If you look at the cylinder, and it is not within its requalification period, check NO. This will stop the formal inspection process. The APP will advise you to take the cylinder in for requalification. When the cylinder is returned from requalification, and you enter the serial number, the system will re-populate much of the previous data.

External (page 6/12)

If nothing is noticed or seen, then no box needs to be checked and you can move to the next page. Or you can check yes on each section and make any necessary notes


if located – check the box and enter any description. List the depth and location based on your primary reference point. Corrosion is any loss of the metal or structure due to environmental conditions.


Cuts or gauges are generally caused by external sources. If paint is scraped, it is not recorded, that is general wear and tear. Loss of the cylinder material is considered cuts and gouges.

Chemicals / Fire Damage

If there are any signs of charring or burns or blistering or peeling, it is listed under this section. Place a description and or location of the damage.

Other concerns

This is a catch all note section for the inspector. If there is anything of concern, or something needs documentation, this is the area to list that information.

Threads (page 7 / 12)

If you find something during the thread inspection, make appropriate notes. If nothing is found or seen, you can move on to the next page without entering any data


if you locate a damaged thread note its location based on your primary reference point and note if it poses a safety risk or needs to be monitored.


Note any corrosion concerns within the threads or at the base of the threads, under the crown region.

Eddy Current test

If an eddy current test was performed list the probe number used and the date the test was performed. If known, you can also identify the certified examiner.

Internal (page 8 / 12)

if you notice anything within the interior of the cylinder make your notations in this area. Remember to mark the locations based upon your primary reference point.


make a notation of any items located within the cylinder that normally do not belong. They could include odors, mark, stains or foreign objects.

Pitting / Corrosion

If noticed mark the location and depths of any damage greater than standard surface scrapes. Using a probe estimate the depth of the damage and the location.

Interior Cleaned

If you performed any cleaning functions list what you did and what you used to clean the interior of the cylinder. You can also mention if it is compatible with the use of oxygen.

Valve (page 9 / 12)

If you did not inspect the valve or it was not with the cylinder – you can move to the next page

Valve inspected

check / activate if you performed an inspection or service

Threads inspected

making any notations. If you marked yes, you must make some type of note or you cannot move forward

Valve working

if you checked the valve function – mark this and make any notes

Dip Tube

Drop down list of yes / no or N/A for industrial cylinders.

Valve (page 10/12)

continuation of what inspection you conducted on the valve

Burst disk checked

Mandatory response required to move through the inspection process. Mark either yes or no

If YES – then you must enter the burst disc pressure you identified. Ensure it is the proper rating for the cylinder. 5/3 the cylinder working pressure or multiply the working pressure by 1.66


if you cleaned the valve, what method and steps did you use. If you don’t enter anything you can’t move forward. Methods might be vinegar bath or the use of an ultrasonic device.

Lubricant applied

what type of lubricant did you use within the cylinder and / or valve threads? Be as specific as possible.

O-ring replaced

Enter the correct O-Ring composition you used for the cylinder.

Cylinder Information (11/12) – Final Grade

Did the cylinder Pass / Fail / rejected / or returned to the owner without any documentation? Any Notes you make are optional.

Inspector Information (12/12)

If you updated your profile during the initial setup, this data should be automatically entered by the APP

Next Inspection

enter the due date for the next inspection


If everything was done correctly the APP will present a CHECK BOX on the bottom right corner. Hitting that button saves the data. If successful it will show GOOD WORK. The inspection is then in your data base.


This is the area where all the inspections are stored. There is also a handy search function at the top of the page. The search can be full name or numbers. Or partial information.

If you hit a specific inspection record the app will show you what was done / completed.

PRINTING the report

In the upper right-hand corner of the inspection’s history page is a DOWNLOAD ARROW. Hit the download button to create a PDF record of the inspection. The App will give you several options including printing, E-mail or texting the report. You can then choose where to send the data.
